Tne ScreNcE or GEoLoey rests upon the fossil contents of the rocks, and, therefore, there can be but little knowledge of the science without a knowledge of the fossils. Every one professes to take an interest in Geology, although the complaint against the technical names is quite general. This work may be regarded as a compilation of these technical names in alphabetical order, with the signification of each, and in this respect, it is a dictionary adapted to the use of evéry one, and designed to remove the objections against the hard words used in the science. The references to authors and publications are for the special benefit of the describers of fossils and the students of palaeontology, while the Groups of rocks are given for the convenience of collectors and students generally. The general plan of the work will be, at once, apparent to the reader; a few remarks, however, in regard thereto, may not be inappropriate. The state of the science, at this time, does not admit of a very great degree of certainty in the arrangement of Paleozoic Fossils into fami- lies; such arrangement must, therefore, be regarded as more or less pro- visional. And, in this work, where a class could not be arranged into families already limited and defined, with approximate correctness, the attempt has been omitted. No new families have been proposed, with the exception of three names, followed by the provisional interrogation point in the Class Echinodermata. The new family names in the Class Lamellibranchiata are used by Prof. James Hall in the fifth volume of the Paleontology of New York. Each generic name is followed by the name of the author, the date of the first publication, the title of the book in which it first appeared, which is generally abbreviated, and the etymology of the word, which is included within brackets. Walid names are printed in Roman letters. Generic names, preoccupied, never defined, and where the fossils are unknown in American palaeozoic rocks, or the names invalid for any other reason, are italicized. The generic name always begins with a capital letter, whether it is a valid or invalid name. Each specific name, or as it was formerly, called the ¢rivzaJ name, is followed with the name of the author, the date of the first. publication, the title of the book in which it appeared, which is generally abbreviated, the Group of rocks in which the fossil is found when the Group is known ; but otherwise the formation alone is given, and the signification of the iv PREFACE. name included within brackets. The name of the Group of rocks is generally abbreviated. Where the author, in the first instance, referred his species to the wrong genus, such generic and specific name is included within parenthesis immediately following the date of the publi- cation. For instance, Delthyris is a synonym for Spircfera, and many species have been erroneously referred to it; such are written in this manner : Spirifera arenosa, Conrad, 1838, (Delthyris arenosa), Ann. Rep. N. Y., Oriskany sandstone. [Sig. sandy.] Specific names never begin with capital letters. The author has endeavored to quote from the original publications, and for kindness and assistance in obtaining access to them, he expresses his - obligations to Prof. James Hall, of Albany, New York; Mr. C. D. Walcott, of Trenton Falls, New York; Prof. Leo. Lesquereux, of Columbus, Ohio, and to Mr. Thomas Vickers, the able and efficient librarian of the public library in the city of Cincinnati. A few of the works cited, how- ever, were not within reach, and the references to these are therefore second hand. In the attempt to make the catalogue of names complete, within the scope of the work, the author visited several libraries and otherwise used reasonable efforts for that purpose, but he has no doubt that a few names have been omitted. The number of names in the book is as follows: Generic names in Roman letters, 1,000 Generic names in Italic letters, > 200 Specific names in Roman letters, 8,000 Specific names in Italic letters, - - 2,000 Total number of génera and species, including synonyms, etc. - - - 11,200 Some of the authors of generic and specific names have not been familiar with the Latin and Greek languages, others have been careless in the exercise of their knowledge when forming the new words, and many names have been misprinted for want of careful proof-reading. For these and probably other reasons, the specific names under a single genus have been found with masculine, feminine, and neuter termina- tions; no uniformity has existed in the terminations added to proper names, and words have been otherwise incorrectly formed. So univer- sally have these errors prevailed, that the author found in some Classes, twenty-five per cent. of the names defective. In a conversation with Prof. EK. W. Claypole, of Antioch College, Yellow Springs, Ohio, (a gentle- man thoroughly learned in the Latin and Greek languages) shortly before commencing the publication, with regard to the etymology of words, and the importance of following the laws of language in making the genders of the adjective specific names correspond with those of the generic terms, he very kindly proffered his assistance, for the purpose of making all proper corrections in this regard. Publication was commenced in February, and the proofs were sent to Prof. Claypole as rapidly as the PREFACE. v matter was put in type for his inspection and correction, but the matter was published so rapidly that it frequently went to press before the return by mail, of his proof. The greater part of the work, therefore, did not have the benefit of his revision. As an illustration, the genus Macrochetlus has been considered masculine by all the authors, and consequently the specific names have been made masculine. As Prof. Claypole did not read the proof, the specific names are published here in the masculine, as the authors made them; but on his authority the species under the genera Temnocheilus, Silenovhallua, etc., have been changed from the masculine to the neuter gender. It may be a question, however, whether usage has not made such genera masculine. No such doubt can arise in the case of the words ending in nema as, Cyclonema, Lowonema, Dictyonema, etc., which have been treated almost or quite uniformly by the authors as feminine; for nema is neuter, in both the Latin and the Greek languages, and there is no reason whatever, for using it as feminine. Where specific names have been formed in more genders than one under a single genus, there seems to be no responsibility in correcting the errors and making the specific names correspond in gender with the genus, and this has been done in several hundred instances in this work. Perfection, however, has not been reached in this publication, and for the purpose of rendering greater assistance in that regard, the ‘‘ Index of Genera” has been made to indicate the gender of each genus, so that any one with a little knowledge of Latin can make the species conform in gender with the genus. The reader will know that generic names are usually coined from Greek words, and specific names from Latin words or proper names with Latin terminations. In Latinizing specific proper names, no uniformity has ever existed, nor can the author claim to have accomplished it in this work. Some authors have used the terminations zanus, dana and canum, while others have used anus, ana and anum. The first impression was that the former endings were proper, and consequently they were used in part of this work; but the best authors use only the latter, and upon reflection we were of the opinion that the latter endings are the proper ones, and they were thereafter used in this work exclusively. The reader is directed, therefore, to correct the proper names ending in ianus, tana and ianum, which occur, in some instances, from the Polypi to the Brachiopoda, by striking out the letter ¢ and thus perfect this class of words. Again, no uniformity exists in specific proper names put in the geni- tive case by adding the Latin ending 7, where the proper names end in €, y, ete. There seems to be no difficulty where the proper name ends in a consonant, in accomplishing the desired purpose by adding a single 2, and petievilly where words of more than one syllable end in e, the same purpose may be accomplished by changing the e to ¢; but there are words where positive difficulty exists, for instance; Case, Casey, White, Whity, Moor, Moore, Hoy, etc. Some would change the e ‘into 2 in Moore vi PREFACE. and add 7 to Moor, so that in each case we would have the same specific name moorz, and so with White and Whity; but there are very strong reasons against such action. In this work, the words of one syllable ending in ¢ have sometimes been written with an ¢ added, and at other times made to end in zz, according to the rules of the British Associa- tion, as casei and casii. But the author is of the opinion that the single letter 7 in these words is to be preferred; thus casei, caseyi, whitei, whityi, moori, moorei, hoyi, ete., for the following reason. The use of such words is justified because the men have been in some way useful to the science, and the preservation of their names is part of the history of its growth, and can be defended with stronger reason than the use of mythological names, even within the limits warranted by the rules of the British Association, where a fanciful resemblance is made a test. A man may devote ten, twenty, or thirty years of his life to the collection of fossils, or he may devote as many years to the study and description of them. In either case his services may constitute the entire history of the fossils of a given locality, and in what way can the science be better subserved than by perpetuating his name among the fossils he discovered or defined’ If the reason for the use of his name is a good one, it is equally strong to use it so that it will not be misunderstood, and can not be made to represent an individual of a different name. The fact that the name does not readily assume a Latin form is of slight weight, in the opinion of the author, compared with the preservation of the history of the science in perpetuating the names of those who have devoted themselves to discover and systematize it. At the request of the author, Prof. Claypole has written an essay upon the rules of nomenclature, for this work, to which the reader is referred for further light in the construction of words. chat (Lee.

A., B. 8c, (London), Antioch College, Yellow Springs, Ohio, The Latin language is universally adopted in the scientific world for naming species, fossil and recent, in both the Animal and Vegetable Kingdoms. Linnaeus introduced the plan of limiting the name of a species to two words, the former of which was generic and the latter specific, and of making these terms in their formation comply with the rules of the Latin tongue. Since his time, this plan has become the rule. At first, terms were chosen expressing the character or characters which define the genus or species, and such names constitute the perfection of scientific nomenclature. But even Linnaeus soon found it impossible to maintain this standard, and himself resorted to Homer's iad to find names with which to christen the butterflies that thronged in upon him. Hence we have Troilus, Danaus, Philenor,&c. Such names are mere arbi- trary, meaningless counters attached to the objects and only tenable by an act of memory. They recall no character and are recalled by none. * Hence they are inferior to the former class of names. But if in Linnaeus’ day their necessity was evident, much more so is it to-day, when almost every language and lexicon have been ransacked to find unpreoccupied names for the hosts of natural objects for which they are required. In some large genera, such for instance as Orthoceras, Orthis and Rhynchonella, it has become exceedingly difficult to coin descriptive names which have not been already thrown into circulation by some other author. This will be evident to any reader in the number of specific names in the catalogue marked “ preoccupied,” and one object is to provide a remedy for the difficulty by enabling any one to see at a glance whether or not any proposed name has been previously published by any American, and to some extent, by any European author. The conventional Latin of the Sciences differs somewhat from the classical Latin of the schools. As a dead language, Latin is free from the changes to which all living languages are subject, and as the most widely studied of the dead languages, it forms an excellent means of communi- cation between men of science in different countries. Words and com- binations of letters have, however, been introduced alien to the genius of the language, and some of them most barbarous and unmusical. *NOTE.—This paper has been prepared at the request of Mr.S. A. MILLER, the author of the AMERICAN PAL.Z0ZOIC FossILs, and With the view of giving some assistance to paleontological students and workers, in avoiding errors and improving the nomenclature of science, HE, W.C, viii CONSTRUCTION OF SYSTEMATIC NAMES IN PALAONTOLOGY. Indeed their introduction cannot well be opposed, as they often offer useful characters. But the laws of Latin should nevertheless control their formation. They should be made, as nearly as possible, what the Roman would have made them had they been introduced from outside into the language while yet living. In this way no violence is done to it, and in all countries words will be formed in a similar manner. In the year 1862, a committee of the British Association for the Advancement of Science, published a set of rules and recommendations on the subject of Scientific nomenclature, the former of which may be said to be a summary of the practice of the best scientific writers in all lands, and therefore binding, and the latter have been, with a few ex- ceptions, almost universally adopted. Thus, alluding to the point above mentioned, the committee in its “ Recommendations ” says: b. Barbarous names.—Some authors protest strongly against the introduction of exotic words into our Latin nomenclature; others defend the practice with equal warmth. We may remark, first, that the practice is not contrary to classical usage, for the Greeks and Romans did occasionally, though with reluctance, introduce barbarous words in a modified form into their respective languages. Secondly, the preservation of the trivial names which animals bear in their native countries is often of great use to the traveler, in aiding him to discover and identify species. We do not, therefore, consider, if such words have a Latin termination given to them, that the occasional and judicious use of them as scientific terms can be justly objected to. In addition to drawing up a mere list of the North American Paleo- zoic Fossils, an attempt has been made to give some help to the many workers in the paleontological field towards rightly naming their fossils at the outset. A mistake once in print is very difficult to eradicate. It reappears, it crops out in some unexpected place and with every reappearance has a new lease of life. Few who have not made some study of the subject have any conception of the confusion now existing in the nomenclature of science. The errors are of two kinds— scientific and grammatical. To such alength has synonymy or the giving of different names to the same species now arrived, that it not unfre- quently happens that the common English name is more definite and vivid, and therefore more useful than the Scientific. Read, for instance, the twelve different names which have been given to the common Chain Coral, from Fougt, in 1765, to Bronn, in 1835. This, in many cases, arises from mistaken identification, which with all care must sometimes hap- pen, but it arises in a still greater degree from the impossibility of learn- ing what species have been found and what names have been given, when they were given and by whom. Another source of confusion is the erroneous nomenclature often adopted. All whose duty calls them to the study of paleontology are not, and cannot be, classical scholars, and consequently not a few names are formed in violation of the recognised rules of janguage. Some errors of this kind have been corrected and afew rules are appended to aid in preventing others. 0. Corrupted words.—In the construction of compound Latin words, there are certain grammatical rules which haye been known, and acted on for two thousand years, and CONSTRUCTION OF SYSTEMATIC NAMES IN PALAZONTOLOGY. ix which a naturalist is bound to acquaint himself with before he tries his skill in coining zoological terms. One of the chief of these rules is, that in compounding words, all the radical or essential parts of the constituent members must be retained, and no; change made except in the variable terminations. But several generic names have been lately introduced which run counter to this rule, and form most unsightly objects to all who are conversant with the spirit of the Latin language. A name made up of the first half of one word, and the last half of another, is as deformed a monster in nomenclature as a mermaid or a centaur would be in zoology; yet we find examples in the names Corcoraz, (from Corvus and Pyrrhocorax), Cypsnagra (from Cypselus and Tanagra), Merulaxis (Merula and Lynallaxis), Loxigilla (from Loxia and Fringilla), etc. In other cases, when the com- mencement of both the simple words is retained in the compound, a fault is still committed by cutting off too much of the radical and vital portions, as is the case in Bucorvus (from Buceros and Corvus), Ninox (Nisus and Noctua), etc. 1. Adjective generic names.—The names of genera are, in all cases, essentially substan- tive, and hence adjective terms can not be employed for them without doing violence to grammar. The generic names of Hians, Criniger, Cursorius, Nitidula, etc., are examples of this incorrect usage.— Recommendations. If a writer is unable to coin such a generic term without falling into these or other errors, it would be wise to abandon the attempt and form one in another manner. RULES FOR THE FORMATION OF NEW NAMES IN PALEONTOLOGY. a. Gender of generic terms—A generic name should always be of that gender which the laws of the language from which it is taken demand. Definite rules cannot well be laid down, because the practice of various languages differs on this point. In general, where no change is made in the termination of the word which forms the end of a new name, the gender of that word will determine that of the name. Thus, the words, stoma, a mouth, and ceras, a horn, are both, in Greek, of the neuter gender; and, consequently, all the many compounds ending with these words, such as Orthoceras, Platystoma, etc., must be of that gender also, and have corresponding specific adjective terms. If the first founder of a genus were to take the pains to ascertain the right gender of his new name, and make his adjective terms accordingly, many errors would be avoided, for subsequent authors, apparently without a thought, in establishing a new species, coin a specific name of the same gender as that originally published, and thus perpetuate and increase error. For example, the word desma, a bond, like almost all Greek words ending in ma, is of the neuter gender; and yet, in a work standing so high as Woodward’s Mollusca, we find Lyrodesma plana, followed shortly after- wards by Cochlodesma practenue. b. Gender of specific terms.—Every specific name must agree in gender with that of the genus to which it belongs; and yet, owing to the above and several other causes, this rule is incessantly overlooked or violated, even by writers whose classical attainments are beyond doubt. In few, if any, large genera do we fail to find two, if not all, the three genders among the specific names. For instance, in the genus Recepta- culites we have Receptaculites fungosum, K.globulare, Rh. formosus, R. x CONSTRUCTION OF SYSTEMATIC NAMES IN PALZONTOLOGY. reticulata. Such terms, being mere errors, pure and simple, and involv- ing no disputed or debatable point, may be reduced to accord without difficulty. ce. Latin and Greek terminations.—The addition of these termina-. tions to old words often requires a previous change in those words the following rules are offered as some assistance to those whose time does not allow the consultation of authorities, scientific and linguistic. It is not always easy for even a classical scholar to determine off-hand how the Greeks or Romans would have made a word, had it been coined by them while their languages were still living. Much examination and collection of examples is necessary before certainty can be reached, and in a few cases some doubt may then remain. These cases are, however, very few, especially as the terminations employed in paleontology are not numerous. The following rules will probably suffice to enable any one with an elementary knowledge of the classic tongues to form cor- rectly a new specific term, but nothing can give full immunity from risk of error where some such knowledge is not possessed. —alis. This Latin termination, implying resemblance, is seldom used, except in words already compounded in Greek and Latin, and when otherwise, it must be annexed to the stem of the word, as rectilateralis, quadrilateralis. —anus. This Latin termination implies resemblance or association, and may be added to proper names, personal or local; though in science its use is almost confined to the former. If the word be capable of tak- ing a classic form, the termination should be simply annexed to the stem as Linnaeus, linnaeanus; Lesquereux, (lescuria) lescurianus; in con- formity with classic usage; pagus, paganus; Claudius, claudianus; Neapolis, neapolitanus. In other cases, the addition of this termination must follow the same rule as those for ensis, as America, americanus; Geonitz, gernrtzanus; Meek, meekanus; Erie, erianus; Italy, (ta) ttalianus. —atus. This Latin termination strictly implies the possession of the thing to the name of which it is added. It is, therefore, affixed to the stem of common names only, as costa, costatus; galea, galeatus; fornia, fornicatus; sinus, sinuatus; stria, striatus, lobus, lobatus; rostrum, rostratus. It is worthy of remark here that this termination sometimes loses its at, to shorten the word. The practice is not commendable from a linguistic standpoint, but some of the terms so made have become fixed in the nomenclature, as Orthis biloba. —formis. This Latin termination implies resemblance of shape, and should be confined to Latin words, to the stem of which it should be joined by the connecting vowel 7, as laterna, laterniformis; pistillum, pistelliformis. In forming terms, such as the first given above from Latin words ending in a, the error of using ae as the connecting vowel should be avoided; being inconsistent with classic usage, as well as more awkward and lengthy, thus we have from terra, terrecola; gemma, gem- miter; squama, sguameger; tuba, tubtformis; ete, CONSTRUCTION OF SYSTEMATIC NAMES IN PALEONTOLOGY. xi —ensis. This is a Latin termination, expressive of locality, and can- not, therefore, be correctly employed except as an affix to the name of a place. This rule has been traversed in few real, but in many apparent instances. Lingula morsensie is an illustration of the former. In accord- ance with law this has been changed to Z. morsi, being given in honor of Mr. Morse. Zygospira cincinnatiensis, Pupa vermilionensis, Car- dium napoleonense, Athyris hannibalensis are apparent exceptions; but these terms are formed from words, which, though originally personal or trivial, have now become local names, and consequently no valid objection can be raised against them. In using this termination the following rules have been generally followed, and are therefore adopted here. The exceptions are very few, and have been reduced into conformity : 1st. If the name of the place ends in a consonant the termination is annexed to the word, as Clinton, clintonensis. 2d. If the name ends in a or e, these letters are dropped and the termination then annexed, as Canada, canadensis; Nebraska, nebrascensis; Minnesota, minnesotensis,; Towa, towensis; Indiana, indianensis; Lasalle, lasallensis; Erte, ert- ensis. 8rd. If the name ends in 7, 0 or uw, that vowel is retained, as Mississippi, mississippiensis; Missouri, missouriensis; Chicago, chi- cagoensis; Colorado, coloradoensis; Chouteau, chouteauensis. 4th. If the name ends in y, that letter becomes ¢ upon the addition of the termi- nation, as Kentucky, kentuckiensis; Alleghany, alleghaniensis; in accord- ance with classic usage, as Stcily, siciliensis. —i, The termination zis to be considered a mere indication of the Latin genitive case, and custom, rather than correctness, has, in some sense, legalized its addition to any name. In practice, however, it is almost restricted to proper names. Thus we have Anighti, Littoni, Flemingi, Ivesi. The Rule of the British Association on this matter runs thus: “In Latinizing proper names, the simplest rule seems to be to use the termination ws, genitive 7, when the name ends with a conso- nant, and ius, gen. 22, when it ends with a vowel.” —icus. This Greek termination implies resemblance and may be added to common names, under the same rules as those given for—ensis, except that in forming the word, a vowel is suppressed if it would pre- cede the termination; thus, Macedon, macedonicus; Italy (ta), ttalicus. It is little used, except in words already existing, as ellzpticus, and, therefore, needs no further notice. —eus. This Latin termination has been occasionally employed, but as it implies “made of,” it is evidently seldom, if ever, admissible in palee- ontology. The term eboraceus, from eboracum, the Latin name for York, is a misnomer and should have been eboracensis. —idae. This Greek patronymic has come into general use as a con- venient termination to express the resemblance running through a family. B. It is recommended that the assemblages of genera, termed families, should be uni- formly named, by adding the termination idx to the name of the earliest known, or most typically characterized genus in them; and that their subdivisions, termed subfamilies, xii CONSTRUCTION OF SYSTEMATIC NAMES IN PALHONTOLOGY. should be similarly constructed, with the termination inw. These words are formed by changing the last syllable of the genitive case into ide or ine, as stric, Striyis, Strigicte, Buceros, Buecrotis, Buccrotidi, not Strivite, Bucwide,—{ Recommendations. It should be borne in mind that in the termination —idae, the @ is short, but in—7nae it is long. —inus. This Latin termination is of wider application and classic usage sanctions its application to both common and proper names, though less commonly to the names of persons. Latin usage, however, restricted its application more than modern scientific practice has done, and applied it mainly to proper names, local terms and living beings; as caninus, alpinus. Hence, such words as rugatinus, sulcatinus, secalinus, taxinus and velutinus are at best suspicious if not illegitimate. This termination, however employed, is subject to the laws given under—ensis. —ites. This termination was early adopted by naturalists to express the fossil nature of the specimen and so prevent confusion, while at the same time expressing resemblance to some existing genus or species. It is a contraction of the Greek word lithos, a stone. In most instances, however, it coalesces with the last vowel of the root and becomes long in compensation. This and long usage in many words, such as Ammo- nites, Belemnites, Pyrites, have completely established the long z, while the gender is determined by that of the Greek word to be masculine. All specific terms in the genus must, therefore, be of this gender. —otdes. This Greek termination, signifying “ like,” should be added only to the stems of words of Greek origin. No connecting vowel is necessary, as one already exists in it. Thus we have dactylos, dacty- loides; discos, discoides. A Lutin form is often used, —ocdews, which, however, obeys the same laws; except that the Greek termination is alike in all genders, while the Latin is inflected as Latin adjectives of similar termination. d. Compound terms.—In forming compound terms as generic or spe- cific names, care should be taken to connect themrightly. If an adjective of three terminations or a noun of the second Latin declension composes the former part of the word, either 7 or 9 may be employed as a connect- ing vowel, the choice being largely determined by the ear. Thus sudco- marginatus is better than sulez-marginatus, and ecrassicaulis than eras- socaulis. If, however, the adjective has but one or two terminations, or the noun be of the first, third or fourth Latin declension, the connecting vowel a should always be employed as tenwistriutus, pinniformis, ilict- folius, retitormis, corniter. The connecting vowel 0 is admissible by Greek usage in all declensions, as Wlodendron, Cycloconcha, Syringo- dendron, Alethopteris, Dictyoncma, Metyopteris, except that where the first part of the word is an adjective ending in—ys, it is shorter and at the same time consonant with classic usage to employ no connecting vowel at all; thus, pachyderma, euryteines, oxeynotus, Platystoma, etc., are better than pachyoderma, euryoteines, oxyonotus, Platyostoma, ete. e. Spelling of new names.— In writing zoological names, the rules of Latin orthography must be adhered to. CONSTRUCTION OF SYSTEMATIC NAMES IN PALAEONTOLOGY. xiii In Latinizing Greek words, there are certain rules of orthography known to classical scholars which must never be departed from. For instance, the names which modern authors have written Aipuknemia, Zenophasia, poiocephala, must, according to the laws of etymology, be spelt pycnemia, Xenophasia, and pecephala. In Latinizing modern words, the rules of classic usage do not apply, and all that we can do is to give to such terms as classical an appearance as we can, consistently with the preservation of their etymology. In the case of European words, whose orthography is fixed, it is best to re- tain the original form, even though it may include letters and combinations unknown in Latin, Such words for instance as Woodwardi, Knighti, Bullocki, Eschscholtzi, would be quite unintelligible, if they were Latinized into Vudvardi, Cnichti, Bullocci, Essolzi, ete. But words of barbarous origin, having no fixed orthography, are more pliable, and hence, when adopted into the Latin, they should be rendered as classical in appearance as is consistent with the preservation of their original sound. Thus, the words Tockus, awsuree, argoondat, kundoo, ete., should, when Latinized, have been written Toccus, ansure, argunda, cundu, etc. Such words ought, in all practicable cases, to have a Latin termina- tion given them, especially if they are used generically. This rule, with its limitations and exceptions has been not seldom departed from in naming fossils. Many names have gained currency, which are needlessly unclassical. At the same time, we meet with marked examples of compliance. Such names as the following stand out prominently—sancti ludovict, cestriensis, are far more correct and pleasing than louzs? and chesterensis, lescuriae or lescurt than lesquer- euri, while Lepidophloios, of Sternberg, should be spelled Lepido- phloeus, in accordance with Latin rather than Greek custom. It is almost unnecessary to add that when a new term is derived from sources purely classical, care should be taken to spell it accurately, and not to disguise or conceal its origin by any attempts to eliminate a letter or two. This, however, has been sometimes done, as for instance, in the name Stenoctsma, Conrad, (in which the etymology is masked by the misspelling) and which will be found written Stenoschisma. f. Mythological names.—In regard to the numerous mythological names, especially those given by the late palaeontologist, to the Canadian Survey, Mr. E. Billings, the following recommendations of the British Association deserve notice: d. Mythological or historical names.— When these have no perceptible reference or allu- sion to the characters of the object on which they are conferred, they may be properly regarded as unmeaning and in bad taste. Thus, the generic names Lesbia, Leilus, Remus, Corydon, Pasiphex, have been applied toa humming-bird, a butterfly, a beetle, a parrot, and a crab, respectively, without any perceptible association of ideas. But mythological names may sometimes be used as generic, with the same propriety as technical ones, in cases where a direct allusion can be traced between the narrated actions of a personage and the observed habits or structure of an animal. Thus, when the name Progne is given to a swallow, Clotho to a spider, Hydra to a polyp, Athene to an owl, Nestor to a grey- headed parrot, etc., a pleasing and beneficial connection is established between classical literature and physical science.— Recommendations, Mr. Billings was, probably, led to adopt the practice by the increas- ing difficulty of finding unpreoccupied names and an unwillingness to encumber the science with more synonyms. xiv CONSTRUCTION OF SYSTEMATIC NAMES IN PALAONTOLGY. g. Personal names.— g. Specific names derived from persons.—So long as these complimentary designations are used with moderation, and are restricted to persons of eminence as scientific zoologists, they may be employed with propriety in cases where expressive or characteristic words are not to be found. But we fully concur with those who censure the practice of naming species after persons of no scientific reputation, as curiosity dealers (e. g. Caniveti Boisson- eauti), Peruvian priestesses (Cora amnazilia), or Hottentots (Klass). h. Generic names derived from persons.— Words of this class have been very extensively used in botany, and therefore it would have been well to exclude them wholly from zoology, for the sake of obtaining a memoria technica by which the name of a genus would at once tell us to which of the kingdoms of nature it belonged. Some few personal generic names have, however, crept into zoology, as Cuvieria, Mulleria, Rossia, Lessonia, etc., but they are very rare in comparison with those of botany, and it is, perhaps, desirable not to add to their number.— Recommendations. Another objection to this kind of name, so many of which have crept into palzontological nomenclature of late years, is that they yield with difficulty, in many instances, to the plastic hand of the classical linguist. The collector or student who stands godfather to a newly discovered fossil, and seeks immortality for some friend or acquaintance by making it his namesake, naturally wishes to keep the name as little changed as possible, lest his purpose should in part fail. On the other hand the classical scholar would rather see the name reduced in some degree to Latin form so that it may offend the eye and ear as little as possible. Between these two a contest arises, and hence we have various forms for words which should be alike, as Barrandi, barrandei; Moort, moorei. Perhaps in this respect it would be wisest to adopt the recommendations of the British Association Committee, quoted on page xi, with a slight modification, and add z for a genitive case where the name ends in a consonant, in a, 0 or w, and 22 when it ends in e, 7 or y, omitting in the latter case the final vowel of the name. h. Nouns as specitic terms.—In those cases, and they are numerous, where a noun is used as a specific name, no change can be made in its termination. Hence, however, inconsistent it may appear to some to see Orthis biloba and Orthis circulus, Productus cora and Productus costatus, side by side, such combinations are accurate. It may, however, be added that adjective terms are preferable, whenever possible. i. Inelegant names.—With the following extract we leave this part of our subject: Names of harsh and inelegant pronunciation.—These words are grating to the ear, either from inelegance of form, as Huhua, Yuhina, Craxirer, Eschscholizia; or, from too great length, as chirostrongylostinus, Opetiorhynchus, brachypodioides, thecodontosaurus, not to mention the Eualiolimnosaurus crocodilocephaloides of a German naturalist. It is needless to enlarge on the advantage of consulting euphony in the construction of our language. Asa gen- eral rule it may be recommended to avoid introducing words of more than five syllables. We have now pointed out the principal rocks and shoals which lie in the path of the nomenclator, and it will be seen that the navigation through them is by no means easy. The task of constructing a language which shall supply the demands of scientific accuracy on the one hand, and of literary elegance on the other, is not to be inconsiderately undertaken by unqualified persons. Our nomenclature presents but too many flaws and CONSTRUCTION OF SYSTEMATIC NAMES IN PALAONTOLGY. xV inelegancies already, and as the stern law of priority forbids their removal, it follows that they must remain as monuments of the bad taste or bad scholarship of their authors to the latest ages in which zoology shall be studied. Etymologies and types of new genera to be stated.—It is obvious that the names of genera would, in general, be far more carefully constructed, and their definitions would be rendered more exact, if authors would adopt the following suggestion: It is recommended that in defining new genera, the etymology of the name should be always stated, and that one species should be invariably selected as a type or standard of reference. The following extract, from the same code, also- bears on the point in question: Nonsense names.—Some authors having found difficulty in selecting generic names which have not been used before, have adopted the plan of coining words at random, without any derivation or meaning whatever. The following are examples: Viralva, Xema, Azeca, Assiminia, Quedius, Spisula. To the same class we may refer anagrams of other generic names, Dacleo and Cedola of Alcedo, Zapornia of Dorzana, etc. Such verbal trifling as this is in very bad taste, and is especially calculated to bring the science into contempt. It finds no precedent in the Augustan age of Latin, but can be compared only to the puerile quibblings of the Middle Ages. It is contrary to the genius of all languages, which appear never to produce new words by spontaneous generation, but always to derive them from some other source, however distant or obscure. And it is peculiarly annoying to the etymologist, who, after seeking in vain through the vast store- house of human language for the parentage of such words, discovers at last that he has been pursuing an ignis fatuus. Besides having often to follow such will-o’-the-wisps, any student who undertakes the task, will soon find it no easy one to ferret out the origin and meaning of veritable scientific names, often made up without distinct allusion to any conspicuous character of the fossil in question, and, occasionally, by men whose acquaintance with the languages is of the slightest kind. After all, care and pains, not a few malformed words and barbarous terms too long current to be now withdrawn from circulation, must ever remain, as corresponding words survive in our common English tongue; marking some age of folly or ignorance in by-gone days of the language. Such terms will serve as memorials, fossil relics, to show to future times the freaks of linguistic development in the early days of Paleontology. INTRODUCTION. % The most ancient rocks known to man had their immediate origin in sedi- mentary deposition at the bottom of an ocean. At this point commences Ge- ology; for previous to this period nothing has been ascertained as to the condition of the Earth. It commences at the base of the lowest rocks discovered, and from thence it investigates the overlying strata, the changes that have taken place, the lapse of time, and the development of animal life, down to the present moment. Were it possible to obtain a transverse section of these rocks at their maxi- mum thickness, at any particular locality, there would be presented to the view an exposure of more than thirty miles, representing the geological column, which is regarded as one continuous whole, from the base to the top. Geologists have adopted various divisions and subdivisions of this column, for the purpose of illustrating the different aspects of the science, But that which subdivides it into groups seems to be the most natural and systematic, and is the classification now generally preferred. In the infancy of geological science, the known strata were divided into for- mations, each of which was supposed to represent a geological period, during which no marked changes occurred in the condition of the Earth or in its or- ganic life. The commencement of each formation was supposed to mark a new epoch of creation, and its close to represent a great cataclysm that destroyed all vegetable and animal organisms. Modern geologists, however, have determined that the evidence of special creations and cataclysms is entirely wanting, and that the formations do not mark geological periods of repose, nor are they any more distinct in their character, from each other, than are the groups into which they have been subdivided. The palxozoic rocks, as understood by geologists, embrace the Permian group, and all that is below it. The subdivision into Archean, Silurian, Devo- nian and Carboniferous formations is retained as a matter of convenience, for the purpose of directing attention, in a general way, to a particular quarter of these rocks. The Archean (most ancient) are the metamorphic rocks. The Silurian is next in order. The Devonian, from Devonshire, England, is a much smaller formation, and is characterized by its fish remains. The Carboniferous forma- tion, so-called from the fact that it contains the great coal deposits of Europe, concludes the series of paleozoic rocks. Other formations contain coal deposits, but they are otherwise so distinct, that they are never in danger of being classed with this formation as originally defined. 2 STRATIGRAPHICAL GEOLOGY. The names used in American Geology, for the purpose of the classification of the strata into groups, have been derived, generally, from the localities at which the rocks have been studied and described. This method of nomenclature is preferred to any other, because the name itself can never mislead as to the mineral structure or relative position of the rocks, and the geologist may visit and study the locality with the certainty that he is investigating the typical group. Prof. Rogers conceived the idea of improving the nomenclature of the paleozoic rocks by dividing themsinto fifteen parts and giving them names sig- nificant of their relative ages. This he did by usi words suggesting meta- phorically different parts of a day, as follows: Primal, Auroral, Matinal, Le- vant, Surgent, Scalent, Premeridian, Meridian, Post Meridian, Cadent, Vergent, Ponent, Vespertine, Umbral and Seral, meaning respectively the formations of the Dawn, Daybreak, Morning, Sunrise, Mounting Day, Climbing Day, Forenoon, Noon, Afternoon, Declining Day, Descending Day, Sunset, Evening, Dusk and Nightfall. Unfortunately for his attempt to substitute another, for the geographi- cal nomenclature then quite well established and susceptible of indefinite ex- pansion, without the use of conflicting terms or words that could mislead the student, there were several extensive groups of rucks full of the remains of ani- mal life, as yet unexplored, and consequently quite unknown to his system. For obvious reasons the nomenclature suggested hy Mr. Rogers has not been adopted, and in all probability never will be. ’ The Archwan formation is divided into the Laurentian and Huronian groups. The Laurentian series of metamorphic rocks forms the base of the geological column, and has an estimated thickness in Canada of 32,750 feet. It takes its name from the Laurentian mountains of Canada. The Hozoun canadense, a fossil Rhizopod, is found at the base of the Grenville band of limestone, which is near the middle of this series. The estimated depth of the Laurentian series to the lowest place at which this fossil has been found is 16,500 feet. Sir W. E. Logan describes the Grenville band as follows: “The general character of the rock connected with the fossil produces the impression that it is a great foraminiferal reef, in which the pyroxene masses represent a more ancient portion, which having died, and become much broken up, and worn into cavities and deep recesses, afforded a seat for a new growth of foraminifera, represented by the calcareo serpentinous part. This in its turn be- came broken up, leaving, however, in some places, uninjured portions of the or- ganic structure. The main difference between this foraminiferal reef, and more recent coral reefs, seems to be, that while with the latter are usually associated many shells and other organic remains, in the more ancient one the only remains yet found are those of the animal which built the reef.” The next series of rocks overlying the Laurentian is called the Huronian, which, on the north shore of Lake Huron and to the eastward, consists of quartz- ites, chloritic slates, bands of limestone chert, jasper and slate conglomerates, not less than 18,000 feet in thickness. On Lake Superior, Sault Ste. Marie, Mamainse, and other places, it is exposed from 10,000 to 16,208 feet in thickness, An approximate estimate of the thickness of this series on Michipicoten Island, says Mr. McFarlane, is 18,500 feet. And if we compare the rocks of Michipicoten Island with those of STRATIGRAPHICAL GEOLOGY. 3 Mamainse, it would appear that the lower rocks of the latter series do not come to the surface at Michipicoten Island, and that the higher rocks of the Michipi- coten series have not been developed at Mamainse, or lie beneath the waters of the lake to the southwest of the promontory. It would, therefore, appear just in estimating the thickness of the upper copper-bearing rocks of the eastern part of Lake Superior (which are Huronian), to add to the Mamainse series the above- mentioned 4,000 feet of resinous traps, or porphyrites, which would ‘make the whole thickness at least 20,000 feet. (Geo. of Can., 1863, pp. 55, 67, 86; Geo. of Can., 1866, pp. 132, 141.) In addition to the Hozoon canadense, only a few fossil species have been described from the Huronian rocks, and these have been placed in genera of uncertain affinity, to wit: Aspidelia, Stenotheca, and Scenella. The metamorphic strata, equivalent to the Laurentian and Huronian series of Canada are described in Safford’s Geological Survey of Tennessee, as many thousand feet thick. Fossil remains of foraminifera have been found in them. They have also been found in the metamorphic rocks of Europe; so that these rocks are no longer called azoic. Next above the Archzean subdivision lies the great Silurian formation, first determined by Sir R. I. Murchison, and named in memory of the ancient Silures, who inhabited Wales, where he first studied the exposure of the rocks. He subdivi- ded it into the Lower Silurian and Upper Silurian formations, and these names have been adopted in this country. The Lower Silurian is much the most exten- sive, and is divided into groups or subdivisions, in ascending order as follows: 1, The St. John’s Group, consisting of black shales and sandstones, resting conformably upon older schistose rocks, at St. John’s, New Brunswick, 3,000 feet thick. (Geo. of Can., 1866, p. 235.) This Group of rocks contains the remains of Paradoxides, Conocephalites, Arionellus, Microdiscus, Agnostus, Orthis, and other fossil genera, The Para- doxides beds near Boston are supposed to belong to it. 2. The Potsdam Group, which takes its name from Potsdam in Northern New York, where it is well developed, and consists of a fine-grained, even-bedded sandstone, traversed by parallel joints. The Potsdam Group is sometimes divi- ded into Upper Potsdam and Lower Potsdam Groups. The sandstones and limestones on the north shore of Belle Isle, and the rocks which, in the State of Vermont are called the Georgia slates, and the red sand-rock, belong to the Lower Potsdam Group. The Upper Potsdam Group is displayed in Minnesota, Wisconsin, New York, Pennsylvania, and other States. In Tennessee the Pots- dam Group is divided into three great sub-groups, in ascending order as follows: 1. The Ocoee conglomerate and slates; 2. Chilhowee sandstone; 38. Knox Group. The Ocoee conglomerate and slates takes its name from Ocoee river, and is 10,000 feet thick, The Chilhowee sandstone takes its name from the Chilhowee Mountain, and is 2,000 feet thick. The Knox Group takes its name from Knox county, and is 7,000 feet thick; making the total thickness of the Potsdam in Tennessee 19,000 feet. Itis from 500 to 2,500 feet thick in Canada, 2,020 at Bonne Bay, Newfoundland, 1,147 feet at the Straits of Belle Isle, about 2,000 feet in Pennsylvania and West Virginia, and from 600 to 800 feet thick in Wisconsin and Minnesota, 4 STRATIGRAPHICAL GEOLOGY. The fossils which chiefly characterize the Potsdam Group belong to the genera Paleophycus, Scolithus, Archeocyathus; Obolella, Camarella, Dinobol- us, Lingulella, Salterella, Bathyurus, Conocephalites, Olencllus and Dicello- cephalus. Gasteropoda and Cephalopoda first make their appearance in the Upper Potsdam, Poor specimens of Cystidea and Crinoidea have been found in this Group. 3. The Calciferous Group, named from the calcareo-silicious character of the rocks. It was called the Calciferous sandrock and Transition rock by Eaton, and the Barnegat limestone, Newburgh limestone, Warwick limestone, Oolitic limestone, Fucoidal layers, and slaty limestone, in the early Geological Reports of New York. It is divided into the Lower and Upper Calciferous Groups. The Upper Calciferous is found in Newfoundland about 1,000 feet in thickness. The Lower Calciferous is the original Calciferous Group of New York. It is ex- posed in Minnesota, Wisconsin, Tennessee, Missouri, Pennsylvania, Virginia, Canada, and other places, usually less than 500 feet in thickness. It is found, however, in Missouri 1,315 feet thick, where it is subdivided into Ist, 2d, 3d and 4th Magnesian limestone, and in Newfoundland 1,839 feet thick. The St. Peter’s sandstone of the Northwest, named from its great development on the St. Peter’s river, belongs to this group. There is in Newfoundland an important series of strata, having a thickness of 2,061 feet, known as division N. of the Newfound- land rocks, which should probably be regarded as part of the Upper Calciferous Group. If so, it would give us a maximum thickness of about 4,000 feet for the Calciferous. Group. The Lamellibranchiata first make their appearance in this Group, while the Gasteropoda and Cephalopoda become numerous. Pleurotomariu canadensis is known to pass from the Potsdam into this Group. 4, The Quebec Group, which takes its name from the city of Quebec, in Canada, where it was first studied, and is subdivided: into the Levis, Lauzon, and Sillery Groups. The Levis division, which takes its name from Point Levis in Canada, comprehends the Philipsburgh rocks which are 4,860 feet thick, in addition to 1,385 feet of the Orleans section, making the whole division 6,145 feet thick. The Lauzon division, which takes its name from Lauzon, in Canada, is about 4,000 feet in thickness. And the Sillery division, which takes its name from Sillery Cove in Canada, is 2,000 feet in thickness, making the maximum depth of the three divisions of this Group 12,145 feet. The Levis division is highly fossiliferous, while only a few fossils are known from other divisions. Some of the fossils of this Group are found both in the Chazy and Calciterous Groups, and the Canadian geologists for a time supposed it to be the equivalent, in some way or other, of these rocks; but later investigations have shown that it has a fauna of its own, and that it itis beds of passage from the Potsdam to the Trenton fauna, in addition to those of the Chazy and Calciferous, 5. The Chazy Group, which takes its name from Chazy, Clinton county, New York, and has an extensive geographical range over New York and Canada, is seldom found over 300 feet in thickness. The upper part of the Ist Magne- sian limestone in Missouri may be the equivalent of this Group, or rather the dark bluish gray semi-crystalline limestones, interstratified with the grayish drab earthy magnesian varieties, destitute of chert, which crop out in some STRATIGRAPHICAL GEOLOGY. 5 places on top of the 1st Magnesian, and are usually classed with it. The Group has likewise been doubtfully identified in Wisconsin and other Northwestern localities. 6. The Birdseye Limestone, which is a well marked Group of rocks in New York, The rocks break with a conchoidal fracture, and the surface presents numerous crystalline spots due to calespar in the tubes of Tetradium jibratum, which it contains in abundance, and from which the Group takesits name. It is not, however, so distinct in its fossil remains as to be characterized and deter- mined elsewhere, and therefore some geologists treat the name as a synonym for the Black River Group. 7, The Black River Group (including the Birdseye limestone or its equiva- lent) which is found in New York, Pennsylvania, Canada and the Island of An- ticosti, and is supposed to underlie Ohio, Indiana and Illinois, for it is again found cropping out under the Trenton Group in Missouri and other places west of the Mississippi. It has a very wide geographical range, and in Pennsylvania attains the important thickness of 5,500 feet. The Orthoceratites, which commenced an existence in the Upper Potsdam, reach their greatest development in this Group of rocks. Some shells are found more than ten feet in length and exceeding a foot in diameter. Other Cephalo- poda are found in abundance, and several new genera commence an existence. The synonyms for the Black River Group in the early geological reports are Mohawk limestone, Base of the Trenton limestone, Blue limestone, Black marble of Isle La Motte, Bald Mountain limestone, sparry limerocks, Transi- tion chequered limestone, Seven foot Tier and Metalliferous limerock. 8. The Trenton Group, which takes its name from Trenton, Oneida county, New York, is found almost everywhere on the Continent, where the Lower Silu- rian rocks are exposed. In New York, Pennsylvania, Kentucky, Illinois, Mis- souri and Canada, its greatest thickness does not exceed 1,000 feet; while on the Island of Anticosti it reaches 1,700, and in Tennessee 2,500 feet. The Galena limestone of Illinois and Wisconsin, and the Cape Girardeau limestone of Mis- souri, belong to it. 3 The limestones of this Group are literally a mass of fossils, and withal so well preserved, that several hundred species and many genera have been defined. No Group of paleozoic strata has been studied with more interest, or has yielded more facts beneficial to science. It is a magnificent museum of well preserved shells, representing almost every character of the ancient population of the sea. 9. The Utica Slate Group, which takes its name from Utica, New York, and seems to be confined in its Geographical range to Pennsylvania, New York and Canada, and reaches its greatest thickness in Pennsylvania at 400 feet. Its syn- onyms are Black slate, Pulaski shales, Frankfort slate and Lorraine shales. 10. The Hudson River Group, which takes its name from the exposure on Hudson River, New York, has an extensive geographical range, and reaches its greatest thickness in Canada, at 2,000 feet. The fossils which characterize it are nearly the same as those which characterize the Trenton Group. The inter- vention of the Utica slate in New York and Canada furnishes the only excuse for separating the two groups. In the Western and Southern States, where the Utica slate is absent from the strata, the upper part of the Lower Silurian is 6 STRATIGRAPHICAL GEOLOGY. generally called the Cincinnati Group, though in Tennessee it is known as the Nashville Group, or more generally it is known as the Blue Limestone. The Cincinnati Group, as exposed in Ohio, Indiana and Kentucky, with which I am better acquainted than with any other Group of rocks, will receive more than a passing notice. The total thickness of the exposure will scarcely exceed 1,000 feet, the lower part of which is probably the equivalent of the upper part of the Trenton Group, and the remainder belongs to the Hudson River Group. The Cincinnati Group, therefore, is of value as a technical name only so far as it ex- presses the absence of the Utica slate, and points to the locality of its exposure. Some fossils, as Bellerophon bilobatus, Strophomena alternata, Zygospira modesta, Leptena sericea, Buthotrephis gracilis, Beyrichia chambersi, Calymene senaria, Isotelus gigas and Isofelus megistos pass entirely through the Group. Trinucleus concentricus, Triarthrus becki, Orthis multisecta, O. emacerata, Streptorhynchus hallia, Ambonychia bellistriata, Modiolopsis cincinnatiensts, Cycloconcha mediocardinalis, Lichenocrinus crateriformis and Chetetes (?) jamesi, are confined to the lower half of the group. G@lyptocrinus decadactylus, G. dyeri, G. nealli, @ fornshelli, Lichenocrinus tubercnutatus, Streptorhynchus filitexta, S. subtenta, S. sulenta, S. sinuata, S. nutans, Orthis insculpta, O. sub- quadrata, Rhynchonella capur, R. dentata, Cypricardites haynesi, Anomato- donta gigantea, A. alata, Anodontopsis millert, Fevistella stellata, Tetradium fibratum and Streptelasma curnicukum, are found only in the upper part of the Group. Some fossils occupy only a few feet in vertical range, as Orthis in- sculpta, Orthis retrorsa, O. emacerata, Glyptocrinus nealli and Streptorhynchus suleata. These facts teach us that during the deposition of the rocks, the fauna of the ocean was constantly changing. One form ceasing to exist at a given place at one time, and another at another time ; a new species appearing at one period, and another at another period. Not, however, indicating cither the ex- tinction or creation of a new species, because though the Orthis insculpia has a vertical range of only about three feet, it is found in the Trenton Group, in New York, in much earlier strata ; and substantially the same may be said of other forms. The Group of rocks, throughout its entire thickness, is composed of alter- nate layers of blue marl and limestone, of varying thickness. In some places the marl is 6 or 8 feet thick, without a layer of stone. At other places, one layer of stone, 4, 6 or 8 inches in thickness, follows another, with intervening layers of marl, of much less thickness, for 40 or 50 feet. It is rare to find a layer of limestone more than a foot in thickness. All the layers are broken into small, irregular pieces, sufficiently large, however, for cellar and other light stone work for which they are used. When the blue marl is exposed for a few years to the action of the weather, it gradually loses its color, and finally presents a dull gray appearance. Where the marl in the bed, only a few feet from the surface, has been changed to the dull gray color, crystals of the sulphate of lime are found on the layers of stone and in the marl. The silicious matter prevails over the carbonate of lime in the layers of marl, while the carbonate of lime is much in excess of the silicious matter in the layers of stone, due in part, at least, to the fact that the stones are almost literally a mass of more or less comminuted shells, corals and crinoids. There is nothing, therefore, in the general character STRATIGRAPHICAL GEOLOGY. 7 and appearance of the stones and marl to indicate the changing character of the fossil contents, to which I shall now call more particular attention. The Zygospira modesta is found throughout the group, varying in size from asmall pin-head toa pea. The largest size has been called Zygospira cincin- natiensis. The smaller specimens differ in their proportional length and breadth and in the proportional elevation of the middle of the ventral valve, and corres. ponding depression of the mesial sinus of the dorsal ‘valve. The larger speci- mens differ in the same respect; and as the number of plications is but little in- creased, they become larger and coarser. The same species from the Trenton Group, at Ottawa; Canada, is more elongated, and more finely plicated than the Cincinnati forms; while specimens from the Trenton Group of Southern Minne- sota are scarcely distinguishable from Cincinnati specimens of medium size. This species passes through the Trenton, Utica and Hudson River Groups, and is found in the Clinton Group. Strophomena alternata is found throughout the Group. Specimens secured within 200 feet of low water mark at Cincinnati, are large, thin, frail, and some- what flat, but in their markings resemble the more profound specimens from the Trenton Group of New York and Ottawa, Canada. Many specimens found from 350 to 450 feet above low water mark are peculiarly thick, firm and heavy. From 450 feet above low water mark to the top of the Group the specimens are, gener- ally, proportionately longer on the hinge line and more distinctly eared than they are below. and frequently much larger. One form of these long eared specimens has been called variety loxorhytis. The variety nasuta is most distinctly marked at an elevation from 400 to 450 feet above low water mark, where it is thicker and deeper than the same variety from the Trenton Group of New York and Canada. The variety alternistriata is most common in the middle and up- per part of the Group. The variety fracta is found only in a vertical range of a few feet about the middle of the Group. This species is widely distributed and ranges from the Chazy to the Clinton Groups, passing through a great many forms, which, if constant or characteristic of pence geological horizons, would be regarded as good species. Leptena sericea is found throughout the ee changing at times in size, length of the hinge line and comparative thickness. It is a common form in the Trenton, Hudson River and Clinton Groups. Strophomena tenuistriata is frail and rare in the lower part of the Group, but quite common and well preserved in the upper part. This, including its nearly related forms, under the names of rhomboidalis and depressa, is almost world wide in its distribution, and ranges from the Trenton Group to the Lower Carboniferous. One could not hesitate, however, in separating the Lower Silu- rian from the Upper Silurian forms, and these again from the Devonian and Lower Carboniferous forms, while remarking the somewhat general resemblance between them. Streptorhynchus hallia is found in the lower 200 feet of the Group, and is not known to occur elsewhere. &. planoconvexa occupies only a few feet in ver- tical range about the middle of the Group. S. nutans, S. planumbona, S. sub- tenta and S. filitexta are confined in their range to the upper part of the Group; though 8. swbtenta is found in the Hudson River Group at English Head, Anti- costi, and S. filitexta in the Trenton Group of New York. 8 STRATIGRAPHICAL GEOLOGY. Streptorhynchus sinuata has a vertical range of only a few feet below the middle of the Group, and 8. sulcata has a vertical range of only a few feet near the upper part of the Group. 7 Orthis bellula, O. plicatella, O. fissicosta, O. ella and Cythere eineinnatiensis are confined within a yertical range of about 100 feet, near the middle of the Group. 0. plicatella, O. (riplicatellu, O. fissicosta and O. jamesi vary much in size and proportional length and breadth and general appearance, and some- times run so close together that it is only by close observation that the species are separated. Orthis ella varies so much in size and number of plications that it could be separated into three forms sufficiently distinct to have specific names, if the forms were found only in distinct Groups of rocks. But, probably, no shell indicates the unceasing change and development of animal life during the deposition of the Group as much as the Orthis lynx. It is found of all dimen- sions, from 1-16 of an inch to 2 inches in length, breadth and thickness. The mesial sinus is usually occupied with three plications, and the mesial fold with four; but sometimes the mesial sinus has only two plications, and sometimes it has four and even five, while the mesial fold always contains one more than the sinus, if the specimen is regularly developed. The more profound the sinus, the fewer plications in it. Some specimens are much longer than they are wide; others much wider than long. Some specimens, with hinge-line shorter than the width of the shell, become globose and nearly as round as an apple, others have the hinge-line prolonged to double the width of the shell, and have nearly the form of Spirifera mucronata. Small specimens of the globose form are marked with about sixteen plications, while the long-eared forms have as many as forty on each valve. Some specimeas have thin shells; while others, no larger, have very thick ones. These extreme varieties do not occupy the same layers of rock, but different strata. Considerable variation exists, however, in specimens occu- pying the same layer; and so many intermediate forms are found in different layers, that the extremes in the Group are linked together. The maximum thickness of the lower Silurian, as shown by the Groups men- tioned, is 48,745 feet; and the fossiliferous part of the metamorphic rocks, 36,- 500 feet; making a total of 85,245 feet, or a little over sixteen miles from the top of the Hudson River Group to the base of the fossiliferous rocks. In other words, if all the Metamorphic and Lower Silurian Groups were fully represented, at their greatest thickness, on the Hudson River or at Cincinnati, we would ex- pect to find fossils by digging or boring at these places for sixteen miles. The fact is probable, however, that part of the earth was dry land, while another part was covered with an ocean; and that the dry land was worn away by the action of rain, and other causes, while the ocean bed, gradually filled up, as the Atlantic fills to-day, by sedimentary deposition. There is no evidence of dry land, during all this period; but the negative evidence to the contrary, in the total absence of land plants and animals. Dry land may have existed, however, in the shape of barren rocks and disintegrated matter,‘for mechanical deposition; but if it did not exist, it is presumed that deposition took place more rapidly at the bed of the ocean at one place than at another, and that the ocean currents removed what had been deposited at one place, and carried it to another; so that, in either case, the maximum thickness of each Group is the measure of the lapse of time STRATIGRAPHICAL GEOLOGY. 9 that transpired during its deposition on the ocean-bed; and these, when placed together, in their order of deposition, constitute the true geological column. The Upper Silurian rocks are subdivided in ascending order, as follows: 1. Oneida Conglomerate, which takes its name from Oneida county, New York. 2. Medina sandstone, which takes its name from Medina, New York. 3. Clinton Group, which takes its name from Clinton, New York. 4. Niagara Group, which takes its name from its development at the Falls of Niagara. 5. Onon- daga Salt Group, which takes its name from Onondaga, New York, where the salt springs have been extensively wrought; and 6. Lower Helderberg Group, which takes its name from the Helderberg Mountains of New York. The Oneida Conglomerate has been called the Shawangunk Grit, the Shawan- gunk Conglomerate and the Millstone Grit. «The word Shawangunk, signify- ing, in the Indian language of the aborigines, White rock, has been regarded as quite appropriate, because it is expressive of the character of the rocks. The greatest thickness of this Group in New York and Pennsylvania is about 500 feet. The rocks are of such a character that they have not preserved the fossil remains with the exception of imperfect fucoidal impressions. The Medina sandstone is usually of a red color, with the exception of a gray band near the top. Between the mouth of the Niagara river and Lewiston, it is 350 feet thick, though at Barton, Canada, it is 618 feet thick. Its dimensions in Pennsylvania are much increased. In the latter State it is subdivided into three Groups on lithological grounds; the lower, a compact greenish gray sandstone about 400 feet thick, the next a soft argillaceous red and brown sandstone and shale 700 feet thick, and the higher a white or light gray sandstone and shales, 450 thick; making a total thickness of 1,1£0 feet. Like other sandstones, it usually contains but few fossils, but in some localities it is highly fossiliferous, especially in the upper part. The Clinton Group is only estimated, in Ohio and other Western localities, at 50 fect or less in thickness. In New York and Canada from 50 to 400 feet, and on the Island of Anticosti at 610 feet; but in Pennsylvania it reaches the great thickness of 1,620 feet. (Geo. of Penn., vol. i., p. 106. ) Prof. Hall says of this group: “In the Western portion of the State (N. Y.) the limit between the Medina sandstone and Clinton Group is well defined, and the materials very distinct; but, in the central part of the State, we find the same conditions which operated during the deposition of the Medina sandstone to have been continued into the Clinton Group. The latter commences by a shaly deposit, which is soon succeeded by alternations of sandstone, in character pre- cisely like the Medina sandstone. The general character of the marine vegeta- tion of the two periods is similar; and a peculiar type of plants commences its existence in the Medina sandstone, and terminates in the Clinton Group. When we examine the Clinton Group in the central part of the State, its analogies are chiefly with the Medina sandstone; and it is there a powerful and important formation, presenting, however, great variation in its successive beds and charac- ters, in every respect truly protean. In its Western extension, the Clinton Group assimilates in character to the Niagara Gruup, and in the Western district has nearly lost the character which it presents in Oneida county. At the same time that the Group assumes a more calcareous character in its Western extension, it 10 STRATIGRAPHICAL GEOLOGY. loses the fossils which were typical of it, and becomes charged with fossils pecu- liar to calcareous strata. Thus, while we find its lower beds, from Wayne county Westward to the Niagara river, characterized by peculiar fossils, we find the upper beds containing many species which pass upward into the Niagara Group. Indeed, there is no line which can be designated between these two Groups, which shall mark the limits of the organic products. It is true, nevertheless, that by far the greater part of the fossils of the two Groups are distinct; and the small number in the lower Group, of those which we regard as proper to the Niagara Group, are for the most part inconspicuous, and not so well developed as they are in the Niagara.” Again, he says: “Jn tracing the Clinton Group Westerly, we find its affinities more with the rocks below, or that the materiat and fossils recognized on the one side as the Clinton formation are not strongly separated from the upper beds of the Hudson River Group; and studied in these localities alone, they might be regarded as constituting part of the same. On the other hand, the Niagara becomes defined as a calcareous Group, and the line between it and the strata below is strongly drawn. The hase of this limestone would everywhere be recognized as the base of the Upper Silurian Rocks, while the strata below are marked by fossils which belony to the Lower Silurian fauna.” The Niagara Group consists of shales and limestones, and may, for the pur- poses of this introduction, include the lenticular mass of dolomitic limestones found in Canada, and bearing the name Guelph Group. The Guelph Group takes its name from the town of Guelph in Canada, where it is about 160 feet in thick- ness. At Lockport and at Niagara Falls, the Niagara Group consists of about 80 fect of shales, and 164 fect of limestones. The Group is found exposed in Ohio, Indiana, Ilinois and other Western States, rarely exceeding 400 feet in thickness; but in Tennessee it reaches 1,700 feet, and is subdivided as follows: ist, Clinch Mountain sandstone, consisting of shales and sandstones, 700 feet; 2d; White Oak Mountain sandstone, 500 tect; 3d, Dyestone Group of shales and sandstones, which takes its name from an iron ore, which is sometimes used asa dyestone, 300 feet; and ith, Meniscus Limestone, which takes its name from a lens or a mepiscus-shaped fossil sponge, named by Roemer, Astrwospongia meniscus, 200 feet. Prof. Hall says: “The rocks of this Group, where best developed in Western New York, consist of a mass of shale, succeeded by one of limestone, the passage from the former to the latter taking place by the gradual increase of calcareous matter, The upper or terminating limestone of the Clinton Group is succeeded ” by a soft argillo-calcareous shale, which maintains its character unchanged for a thickness of 80 to 100 fect. Throughout the greater part of this it abounds in fossils, nearly all of which are distinct from those in the beds of the Clinton Group. In the Western part of New York, the lithological characters of the Clinton and Niagara Groups are so similar, that they could well be united. The fossils also of the two Groups, though generally distinct, are nevertheless generic- ally similar, and several species pass from the lower to the higher Group. Still farther West, the assimilation becomes more perfect, and there appears to be no line of separation between the two Groups, At the same time the fossils appear to be commingled.” STRATIGRAPHICAL GEOLOGY. 11 The Onondaga Salt Group is sometimes called the Onondaga limestone or Gypsiferous series. Its outcrop in New York is traced, says Prof. Hall, trom Montgomery county, where the formation is represented by a thin band, West- ward into Wayne county, where it attains a thickness of 1,000 feet, and thinning out towards Canada, it crosses the Niagara river, at 300 feet in thickness, whence it is traced Northwestwardly to Lake Huron, and thence to Mackinac. It is also exposed in Pennsylvania, where it was called the Surgent red marl, and in West- ern and Southern localities. In its lower part, it is made up chiefly of marls and thin shaly limestones, which include the gypsum and salt. Its upper portion consists of magnesian limestones, often yielding hydraulic or water lime, and is hence sometimes distinguished as the Water Lime Group, where it really forms part of the Onondaga Group. The Lower Helderberg Group has a wide geographical range, but is not sus- ceptible of subdivision into many Groups, at any great distance from the Helder- berg Mountains, where Vanuxem separated it into ; 1st, Water Lime Group or Tentaculite limestone ; 2d, Pentamerus limestone; 3d, Delthyris shaly lime- stone ; 4th, Encrinal limestone ; and 5th, Upper Pentamerus limestone. The Water Lime Group was so called from its yielding hydraulic cement, and is about 200 feet thick in New York, and thins out in Canada in a Northwesterly direc- tion. Pentamerus limestone took its name from the Pentamerus galeatus found in it, in Cherry Valley, New York, where it is about 30 feet thick. The Delthy- ris shaly limestone was so named from the abundance of Spirifera macropleura, and S. pachoptera, formerly called Delthyris, found in it. It is about 70 feet thick. The Encrinal limestone is about 25 feet thick, and was so named from the quantity of broken encrinites it contains. It has also been called the Seu- tella limestone, from a shield-like pelvis of a crinoid found in it. The Upper Pentamerus limestone is about 75 feet thick, and was so named from the abund- ance of Pentamerus pseudogaleatus with which it is characterized. The Lower Helderberg attains the greatest thickness of 2,000 feet, at Gaspe, Canada. It is 1,720 feet in Pennsylvania, 400 to 500 in New York, and from 100 to 200 feet thick in the Western States. The fossils of this Group are quite similar to those of the Niagara, and mark a very gradual development from the former to the latter. The Water Lime Group is especially characterized by large crustaceans of the genera Lurypterus and Pterygotus, the highest forms of organized life, which, so far as we know, had, up to this period, appeared upon the earth. The rocks of the Upper Silurian formation, as shown by the preceding esti- mates, are about 8,000 feet in thickness. They contain the fossil remains of no vertebrate animal so faras yet known. They show the uninterrupted course of oceanic life from one Group of rocks to the next, and the gradual appearance of higher organisms, and yet they are without land plants, save perhaps a species of Psilophyton, and vertebrate animals, even of the lowest oceanic types. -The student of biology and the laws of evolution may pause here and reflect upon the fact, that from the geological horizon of the Hozoon canadense, we have passed upwards through nearly eighteen miles in thickness of oceanic deposits, which represent many millions of years as we understand the laws of deposition, and while the changes in the forms of life have been numerous and wonderful, and 12 STRATIGRAPHICAL GEOLOGY. the development into higher forms constant throughout the whole period, yet that life had found its most complete development in a lowly organized articu- late animal—the awkwardly constructed, loosely thrown together—flimsy Lurypterus. The Devonian formation was so named by Murchison from Devonshire, Eng- land. It is subdivided in ascending order into: Ist, Oriskany Sandstone; 2d, Upper Helderberg Group; 3d, Hamilton Group; 4th, Portage Group; 5th, Che- mung Group; and 6th, the Catskill Group. The Oriskany Sandstone takes its name trom Oriskany, in Oneida county, New York. It has a wide geographical range, being found in Canada, New York, Pennsylvania, Maryland, Illinois, and other States. Its: maximum thickness is placed at 300 feet. Prof. Hall says: “The line of demarkation between subordinate Groups, and the line of separation between systems, are equally strong, and that the whole series may be regarded as a succession of minor Groups; that the strong lines of division are almost always due to the absence of some formation, which if present, would show a gradation to the next; and these subdivisions into systems have been made dependent on the imperfection rather than the perfection of the se- quence. Thus the strong line of demarkation between the Silurian and Devonian which exists where the lower Helderberg Group is absent, is softened to a gentle gradation through the intervention of these strata and the Oriskany sandstone. Where these are present in all their members, the line of separation becomes less sharply defined, and we have some evidence that there may exist other intermedi- ate members, or a more full development of those now known between the two formations.” (Pal. of N. Y., vol. iii., p. 35.) In Southern Illinois, the Oriskany sandstone of the Devonian system is un- derlaid hy a Group of silicious limestones, that in their upper beds contain well marked Devonian fossils, and below those that seem to be characteristic, Upper Silurian forms; thus forming beds of passage from the Upper Silurian to the Devonian systems. This Group seems to hold about the same relation to these two systems that the Anticosti Group of Canada holds between the Upper and Lower Silurian of that country. This Group is called the “Clear creck lime- stone,” and is limited in its outcrop to the counties of Jackson, Union, and Alex- ander, first making its appearance in the bluffs of Mississippi, ut the lower end of the ridge known as the “Devil’s backbone,” in Jackson county, and continuing along the river bluffs to Clear creek, in Union county, where they are fully developed, and where they probably attain their maximum thickness of from 250 to 350 feet. (Geo. of Ill, vol. i., p. 125.) Subsequent investigations, and a more complete collection of the fossils which belonged to the upper and lower divisions of the mass, led to the conclusion that the upper division represented, at least in part, the Oriskany period, and the lower, the Delthyris shaly beds of the Lower Helderberg series. And in accordance with this view, without any well marked line of separation on lithological grounds, but supported hy an ex- amination of the same beds in Perry county, Missouri, the upper 260 feet, at the maximum thickness, is placed in the lower division of the Oriskany period, and the lower 200 feet, at the maximum thickness, is placed in the Lower Helderberg period. (Geo. of IL, vol. ii., p. 8; vol. iii, p. 24.) STRATIGRAPHICAL GEOLOGY. 13 The Upper Helderberg Group, in its fullest development, consists of four members, the Caudagalli grit, the Schoharie grit, the Onondaga and Corniferous limestones. The first, when characteristic, is a dark, gritty slate, which has a cleav- age vertical to the line of deposition, and is generally destitute of fossils; but with surfaces, covered with curved, fucoid-like markings, which have given it its name. This rock constitutes beds of passage from the Oriskany sandstone, and graduates above into the Schoharie grit, which is an arenaceous limestone, weathering to a brownish color, and succeeded by the gray, subcrystalline, coral- line formation, which is known in New York as the Onondaga limestone, while the Corniferous limestone consists of the higher dark-colored chert beds of the Group. (Hall’s Pal., vol. iii., p. 43.) The Caudagalli grit was named from a fucoid having some resemblance in form to the tail of a chicken cock. It has a small geographical range, and its maximum thickness in New York is placed at 70 feet. The Schoharie grit, named from Schoharie, New York, has a small geo- graphical range and no considerable thickness. In Pennsylvania and New Jersey, where the Caudagalli and Schoharie grits have been called the Post Meri- dian grits, they have a thickness of 300 feet. This Group in New York consists of a fine grained calcareous sandstone, somewhat resembling the Oriskany, but bearing quite different fossils. No vertebrate animal has yet made its appearance. The Onondaga limestone is only from 20 to 50 feet thick in New York, and, though traced over a great extent of country, rarely exceeds that thickness. In Missouri it is said to vary from 10 inches to 75 feet in thickness, but there are few if any Western localities where this Group can be separated from the Cor- niferous. The Corniferous limestone was named from the chert found in it, which breaks with a corny fracture. It varies from 100 to 200 feet in thickness, in Ohio, Indiana, Hlinois, Pennsylvania and New York. ‘It is from 300 to 400 feet thick in Michigan, and reaches its maximum of 850 feet at Tilsonbury, Canada. At Louisville, Kentucky, this Group consists of a mass of fossil corals, in a bed of hard limestone. It has the appearance of having been a coral reef, and has been so designated, but the limestone is so firm that perfect specimens of the corals are not easily procured. This is the Group of rocks in which the first remains of vertebrate animals are found. These remains consist generally of the teeth of fish, but other hard parts are also found, Some strata are known which are literally a mass of fish teeth cemented together in a compact limestone. Land plants become more com- mon in this Group. The maximum of these subdivisions of the Upper Helderberg Group is there- fore 1,225 feet. Each subdivision in New York is characterized by distinct fos- sils, but in Canada several of the most characteristic species of the Oriskany sandstone ascend through each of the overlying Groups into the Corniferous. _ From this time forward, the five sub-kingdoms in animal life are represented ini every Group of rocks capable of their preservation, viz. : Protista, Radiates, Mollusks, Articulates, and Vertebrates. They all continue to change and de- velop, but the great field of evolution is well nigh surrendered to the Vertebrates, 14 STRATIGRAPHICAL GEOLOGY. which have commenced an existence in the lowest forms of marine fish, soon to appear in higher states of perfection, and to be followed by a number of Ba- trachian or Reptilian forms before the close of paleozoic time. The Hamilton Group was named by Vanuxem, from Hamilton, Madison county, New York. In its fullest development, it consists of the Marcellus shale, Ludlowville shale, Encrinal limestone, Moscow shale, Tully limestone, and Genessee slate. It is about 1,200 feet thick in Eastern New York, and 1,150 feet in Eastern Pennsylvania. It thins out Westerly and Southerly, but maintains a thickness of from 300 to 600 feet in Canada. Prof. Hall says: “The Hamilton Group consists, in Eastern New York, at base of the black Marcellus shale, including some bands of Goniatite limestone. Next succeeds a hard, compact, calcareo-arenaceous shale, which, under atmos- pheric influences, crumbles into angular fragments. This is followed by more arenaceous bands, and by bands of soft slaty shale, with arenaceous shale or ar- gillaceous sandstone, and with some thin bands of limestone, which are almost en- tirely composed of organic remains, Toward the Western part of New York the coarser materials gradually diminish, and we find an increasing proportion of soft shales, with a more general diffusion of the calvareous matter, and thé mass is terminated hy a limestone, Finally, from the Genessee river to the Western limits of the State, the entire Group, above the Marcellus shale, which is persis- tent, consists of dark, soft shales and bands of limestone. ‘Thus the lithological characters are at the East, an olive shale and sandstone; at the West, a grayish- blue, calcareous shale, with bands of limestone. (Pal., vol. iii., p. 46.) The Portage Group was named from Portage, New York. It is 1,400 feet thick in the Eastern part of the State, and 1,150 feet thick in Eastern Pennsylva- nia. It thins out Westerly and Northerly. The Black Slate or Huron Shale of Michigan and Ohio belongs to this Group, and is from 300 to 400 feet thick. It is from 100 to 200 feet thick at Louisville, Kentucky, and New Albany, Indiana, and 50 feet thick in Missouri. The Group ought not to be called the Huron Shale either in Ohio or elsewhere, because that name was appropriated by the early Canadian geologists, and applied to a Group of Metamorphic rocks. If one were to speak of the slate in the Huronian Group, it would be called the Huron Slate, and so would shale if found there, be properly designated as Huron Shale. The words Huron and Huronian have the same signification, and are too near alike to be used to designate widely separated Groups of rocks. The ‘‘ Huron Shale” is a synonym for the “ Portage Group,” with nothing to commend its use, because it has neither geographical nor local significance. The Chemung Group was named from Chemung, New York, and is about 2,000 feet thick in the Eastern part of that State, but at Huntington, Pennsylvania, it is 3,200 feet in thickness. It thins out to the West, and is estimated at only 400 feet in Ohio, where it is called the Erie Shale, and 200 feet in Missouri. While the Hamilton, Portage and Chemung Groups in New York are, combined, only about 4,000 feet thick, and in Pennsylvania do not much exceed 6,000, at Gaspe, Canada, they are 7,036 feet, though this estimate may include the Catskill Group. The passage from the Silurian formation to the Devonian at Gaspe, Canada, where the rocks are exposed 9,000 fect in thickness, is not evidenced by any STRATIGRAPHICAL GEOLOGY. 15 change in lithological character, and is hardly determinable from an examination of the fossils. The lower 2,000 feet is classed with the Helderberg Group in the Silurian, but it may include the Oriskany sandstone of the Devonian series. The upper 7,036 feet are supposed to represent all the other Groups in the Devonian formation of New York, but the divisions are not clearly defined as in New York, nor readily separable from an examination of either the fossils or the rocks. (Geo. of Canada, 1863, p. 396; do. 1866, p. 260; Hall’s Pal., vol. iii., p. 45.) A very interesting Group of rocks, because of the highly fossiliferous charac- ter and abundance of Goniatites, is exposed at Rockford, near Seymour, Indiana, which probably represents part of the Chemung Group; though Prof. Meck and the Illinois geologists have regarded it as the representative of the Kinderhook Group. The shales and sandstones of the Catskill Group form in their greatest ex- pansion at the Catskill Mountains, from which the Group takes its name, a mass of at least 3,000 fect in thickness. The Group is composed of red and greenish or olive shales and shaly sandstones, with some gray and mottled sandstones and conglomerates. In Pennsylvania this Group is divided into: 1st, Ponent Red Sandstone, which is 5,000 feet thick in its Southeastern outcrops; 2d, Vespertine, Conglom- erate and sandstone, 2,660 feet in thickness, near the Susquehanna, making a total thickness of 7,660 feet. The rocks of the Devonian age are therefore 15,235 feet, or nearly three miles in thickness, and are connected together by their interlocking fossil contents, and united with those of Silurian age, precisely as the Lower Silurian Groups are re- lated to each other. The Devonian rocks are followed bythe Carboniferous, which are divided into: 1st, Lower Carboniferous ; 2d, Carboniferous Conglomerate ; 3d, Coal Measures ; and 4th, Permian. The Lower Carboniferous Group, in Nova Scotia, consists of -reddish and gray sandstones and shales, conglomerates and thick beds of limestone, with ma- rine shells and gypsum, and is 7,636 feet in thickness. On the island of Bona- venture, itis about 2,000 feet in thickness, or with the Carboniferous conglomer- ate 2,766, and contains the Fatonia pecnliaris, which is found in the Oriskany sandstone of New York. In Illinois, the Lower Carboniferous is subdivided into Groups in ascending order as follows : 1st, Kinderhook Group, from 100 to 150 feet ; 2d, Burlington Group, from 25 to 200 feet ; 3d, Keokuk Group, from 100 to 150 feet ; 4th, St. Louis Group, from 50 to 200 feet ; and 5th, Chester Group, from 500 to 800 feet. In Missouri, it is subdivided in ascending order, into: Ist, Encrinital limestone ; 2d, Archimedes limestone; 3d, St. Louis limestone ; and 4th, Ferruginous sandstone ; the maximum thickness of which is only about 1,200 feet. The Burlington Group has been called the Encrinital limestone, and in Missouri it is 500 feet thick. The Keokuk limestone is the Archimedes lime- stone of Owen. The Warsaw limestone is sometimes called the second Archi- medes limestone. The St. Louis limestone was called the Concretionary lime- stone by Owen. The Chester Group has been called Kaskaskia limestone, Up- per Archimedes limestone, and Pentremital limestone. In Tennessee, the Lower Carboniferous is subdivided into the Mountain limestone and Siliceous Group. 16 STRATIGRAPHICAL GEOLOGY. The total thickness is about 1,200 feet. In Ohio the Group is subdivided into the Cleveland Shale, Bedford Shale, Berea Grit and Cuyahoga Shale, these to- gether constitute what isalso known as the Waverly Group, named from the quarries at Waverly, Ohio. In Michigan, Prof. Winchell subdivided the Group into the Marshall Group, Napoleon Group, Michigan Salt Group, and Carbon- iferous limestone, the total thickness of which is 550 feet. In the Anthracite Coal region of Pennsylvania this Group has a maximum thickness of 3,000 feet, and consists mainly of red shale; it thins out rapidly towards the Northwest, but maintains a great thickness Southwardly through Virginia and into Alabama, gradually changing its character, however, to a calcareous limestone. The Lower Carboniferous rocks present us with a greater number of species of Crinoids, and these in greater profusion than all the other subdivisions of the Paleozoic rocks. A single locality at Burlington, Iowa, in the Burlington Group, has furnished about 350 species. Another locality at Crawfordsville, Indiana, has almost a world-wide reputation for the great beauty, perfection and abun- dancy of its crinoids. It is in the Keokuk Group. The genus Nautilus among the Cephalopoda is clearly recognized and is quite abundant, while the genus Orthoceras, whose perfection represented an or- ganization akin to the embryonic form of the Nautilus has become correspond- ingly rare. The Carboniferous conglomerate is 1,400 feet in thickness in Pennsylvania, and entirely thins out before reaching the Mississippi river. It is only from 100 to 200 feet thick in Ohio. Prof. Hall says: “It was evidently formed from the fragments of older for- mations, drifted, water-worn, rounded and deposited with the larger pieces at the base, and the whole cemented together with’ smaller pebbles and sand. The depth of the formation in Pennsylvania, and its thinning out to the North and West, shows the current to have been from Southeast to Northwest, and probably indicates the close proximity of the source in a Southeasterly direction. In Michigan the thinning out is toward the South, or in a contrary direction. In Illinois the formation thins out from the West toward the East. The character of this formation, its manner of deposition, the currents which must have existed to distribute it, all indicate that this continent was an archipelago at the era of the Carboniferous conglomerate.” In some places the conglomerate is a quartzose grit used for millstones, and it is hence called the Millstone grit. The Coal Measures are 14,570 feet thick in Nova Scotia, 8,000 feet in Penn- sylvania, 2,500 feet in Tennessee, 2,000 feet in Ohio, 1,200 feet in Illinois, 640 feet in Missouri, 2,000 feet in Kansas, and a greater thickness in Nebraska, This Group is sometimes divided into Upper and Lower Coal Measures, a separation that seems to be founded upon the fossil contents in many places. Land Plants, which began their existence in the Devonian era, if we except Psilophyton princeps, became a)yundant in the Coal Measures. They are distri- buted through the rocks, the shales, and the coal. Marine Vegetation, the growth of the Marsh, and the Flora of dry land, existed in immense quantities, and was widely distributed, but the higher orders of plants and forest trees were yet un- known on the face of the earth. STRATIGRAPHICAL GEOLOGY. 17 Among the Cephalopoda, numereus genera and species had disappeared. - The Nautilus the highest form then developed, was common, and furnishes us with several subgeneric types, thus manifesting its prosperity,and pointing to its con- tinuance in succeeding strata; while the Orthoceras had become rare and diminu- tive, preparatory to interring the last of the family in this Group of rocks. Among the Gasteropoda there was a decided advancement from the marine forms, to the land snails of the genus Pupa. Among the Articulates the progress in animal life was still more clearly manifested, not only in the appearance of the marine forms of the genera Hu- proops, Acanthotelson, and Anthrapalemon, but in the appearance of terrestrial insects of the family Neuropteride; Myriapods of the genera Foscorpius, Ma- zonia and Architarbus; while the Trilobites that swarmed in frail hulksin earlier days gradually became extinct. ; The wheel of evolution rolled yet more rapidly among the Vertebrata. The fish became more diversified and more highly organized. Amphibian animals made their appearance in several families, some of them were protected by scales, others were not; some had long vertebral columns, others had short ones; some had limbs well developed, and in form were lizard-like, while others were desti- tute of limbs or possessed them weak and half developed. The Permian Group was so named by Murchison from Perm, a government in Russia. This Group is known only in the country West of the Mississippi, and is so intimately connected with the Coal Measures as to be hardly separable. Its maximum thickness does not exceed 500 feet. The maximum thickness, therefore, of the Carboniferous Groups may be placed at 24,100 feet. The Carboniferous rocks, as found in the Uinta Mountain Region, have been subdivided by Powell and others, into four Groups, viz.: Lodore Group, Red Wall Group, Lower Aubrey Group and Upper Aubrey Group. The maximum thickness of the Groups forming the Paleozoic rocks of North America, as here shown, is as follows: DaUPen tats. 2.. wcdancacen 26s Here e iie Ped nena dae 32,750 feet.

This is a little over 28 miles, all of which is known to be fossiliferous, except the three miles at the base. It may be, that the thickness of some of the Groups is overestimated, and it may be, that two Groups, which are estimated, were de- posited at the same time, and that only one of them should be counted; but on the other hand, it may be, that some Groups are entirely omitted, and that others have not been measured at the place of their greatest thickness. The probability is, therefore, that the maximum thickness of the Groups, when more certainly as- certained, as it will be by future explorations and measurements, will not fall much, if at all, below the present estimate. The limestones of the Paleozoic rocks were formed in clear ocean waters, from the remains of calcareous shells, Their formation must have been ex- 18 STRATIGRAPHICAL GEOLOGY. tremely slow, so slow, that a foot may represent a thousand years, or even more. The shales, clays and marls nay have been deposited with greater rapidity; but when we consider, that the change from one kind of rock-forming material to an- other indicates a brexk in the continuity of time, and that great lapse of time was necessary for the growth of the marine and land vegetation, which formed the coal found between beds of elay and shale, we are led to the conclusion, that the time which clapsed between two separate beds of clay and shale, or marl, added to the time necessary for the deposition of their materials, will, on the whole, make their formation as slow as that of the limestones. The sandstones and conglomerates, particularly those of the Coal Measures, seem to have been made up of trans- ported materials, und were therefore deposited much faster than the limestones, though but few of them appear to have been made with any rapidity. The even- ness of the strata, over a great extent of country, indicates slowness in trans- portation and deposit. The fact. that the materials must have been taken from pre-existing rocks, by the water, before transportation, tends again to convince us of the slowness of their formation. From these considerations, it would not be extravagant to say, that paleozoic time represents more than one hundred millions of years, and we would close our eves against the testimony of the rocks, were we to conclude that paleozoic time could be estimated by years less than many millions. The vegetable kingdom hegan with the lowest of its kind, the alge or sea weeds, and with the lowest forms of these. The development was as gradual as the deposition of the strata. It was not until the Devonian age, that Jand plants appeared of sufficient firmness for preservation, if we except Dawson's Ps/lophyton, which probably grew in a marsh. These were of the lowest classes. They be- came more diffuse and diversified with the lapse of time; but the paleozoic cra closed without the appearance of any of the higher orders or classes. The animal kingdom likewise began with the lowest of its kind, the Muzoon canadense. The learned Dr. Haeckel has established the fifth sub-kingdom in animal life to include forms below the /twd/atu, and therefore very nearly related to inorganic matter. This sub-kingdom he has called Prof/sta, The Lozoon cauadense, under this classification, belongs to the order Polythalaméa, sub-class Radiolaria, class Rh/zopoda, sub-kingdom Profista, Aves passed, about whieh we know very little, before the period of the St. John’s Group, which ushered in the lower Silurian. At this time we find the lowest forms of the Radiates, Mol- lusks and Articulates. The Articulates are represented by the lowest forms of theTrilobites, which, in their perfect state, represented the embryonic condition of the existing Limulus. Millions of years pass by again, before the appear- ance of Gasteropoda, and Cephalopoda, in the Upper Potsdam Group; meantime the system of life, which commenced with the lowest forms, as if by spontaneous generation, by evolution, increases specics and genera and reaches a higher and still higher grade of development. Later still, in the Calciferous Group, the Lamelli- branchiata commenced its existence; a class that has fought its way through all succeeding time, and is even now in the height of its prosperity and advancement. All classes of life, which existed in the ocean, up to the first appearance of the Lamellibranchiata, continued to live, develop, increase their species and genera, and improve, through millions of years, before the Vertebrates first made their ap- STRATIGRAPHICAL GEOLOGY. 19 pearance in the Devonian seas. During all this time, the earth was barren and lifeless. Mighty changes had taken place, mud had been deposited on the bed of the ocean many miles in thickness, and life had grown from its minéral origin in the ocean, until it had nearly the strength to maintain itself on land; but all this had been accomplished as silently as the earth moves in her orbit. The ‘same gradual development continued throughout each sub-kingdom to the close of the Carboniferous period. The evolution in animal forms was as slow as time, and quite as monotonous, except in the constant progress to a higher and more complicated existence. The Coal Measures furnish us with fish-like remains, having the limbs of a frog or the breathing capacity of a tailed batrachian. Several genera have been made from the fossil remains of this period, which bridge the chasm, from the Ganoid fish to the batrachian and the lacertian. The highest Paleozoic type of animal life, yet known, Prof Dawson has called Hylonomus lyelli. The distinguished principal of McGill College says, that it pre- sents characters partly allying it to the newts and other batrachians and partly to the true lizards. The structure of the skull and vertebre resembling a batrachian, and the well developed ribs, broad pelvis, and cutancous covering assimilating it to the true lizards. The following inferences are therefore to be drawn from the testimony af- forded by the Palseozoic rocks: First. That the maximum thickness of the Groups of strata is from twen- ty-five to thirty miles. Second. That it required many millions of years for the formation of these Groups. . Third. That both vegetable and animal life commenced an existence, in the lowest forms, such as might have been produced by a concentration of chemi- cal forces, or, by what has been called spontaneous generation. ‘Fourth. That, by processes of evolution, vegetable life developed from marine forms to land plants. Fifth. That animal life began in the sub-kingdom Protista; from this sub- kingdom, by processes of evolution and the survival of the fittest, there arose Radiates, Mollusks, Articulates and Vertebrates. Each of these sub-kingdoms is now in the highest state of its development, though many families and some orders in each sub-kingdom have had their day and become extinct, or have been on the decline for untold ages. WG Ee a ING IDG) M1 ee La Ee The genus Prototaxites was founded by Dawson upon fossil wood, supposed to resemble the genus Taxites. The sameauthor founded the genus Nematorylon, upon what he supposed to be nearly related fossil wood. Mr. Carruthers examined the same specimens and pro- nounced them both Alge, and founded the new genus Nematophycus. Seeds, stems, roots and other organs of uncertain affinity, have received generic and specific names. Some fossils are classed by some authors with the Algze, as Cruziand, Scolithus, etc., while others regard them as tracks of marine animals. Authors are notin accord, even on the arrange- ment of the fronds and branches of ferns into families. For these reasons, I have not’ undertaken to arrange the fossils of the vegetable kingdom, represented in the paleeozoic rocks, into families. AcantHoruyton, Dawson, 1862, Quar.

[Ety. proper name.] —NOTE.— The author has been informed that Mr. J. M. Clarke has described a new genus and three new species of Phillocaridw, which will probably appear in the Am. Jour. Sci. & Arts, for February, 1833, viz: Diptetocaris pescerve, D. pennidedali, and D. procne—all from the Chemung. Prof. E. W. Claypole says there is little or no classic ground for printing e in the beginning of the second part of a compound word, such as rugestriatus. It should be rugistriatus. An exception occurs when the first part of the word is merely a prefix, as in sube@qualis. That nebraskensis should be written instead of nebrascensis, as there is no ground for using the c instead of k. And that the generic name Chariocephalus should be written Charitocephalus. Mr. Henry Nettleroth has described, under the title of ‘‘ Fossil Mollusca of Kentucky,”’ for vol. 1 of that State, which is now in press, Aviculopecten cancellatus, A. concentricus, Paracyclas octerlonyi, Tellinomya striata, Modiomorpha charlestown- ensis, Millerella (n. gen.) jonesi, Spirifera euruteines, var. erecta, 5. euruteines, var. elongata, S. byrnesi, S. hobbsi, S. davisi, S. meconathyi, Rhynchonella gainesi, Eu- omphalus protteri, Cyclonema clarki, Cyrtoceras hydraulicum, Murchisonia tubereu- ata, Platyceras nodulosum, P. elongatum, P. compressum, and Orthis goodwini, from the Devonian formation; and Spirifera knotti, Pentamerella schwartzi, Rhynchonella compressa, Pentamerus foggi, P. trigonalis, P. louisvillensis, and Stricklandia louis- villensis, from the Niagara Group; and Cypricardites halli, from the Hudson River Group. INDEX OF GENERA. In addition to indexing the Genera in the whole work, the gender of each genus is designated—m, for masculine; f, feminine; n, neuter. typ eg. ts a PAGE. PAGE.
