MCCLURG And Co, A.D. 1888 $ Museums PREFACE TO THE FIFTH EDITION. THIS book is designed to give to students and collectors a ready means of identifying the Vertebrate fauna of the region which it covers, and of recognizing the characters on which the families, genera, and species of these ani- mals are founded. To these ends, I have made use of a system of analyti- cal keys by which differential characters are brought into contrast. The usefulness of such keys has long been recognized by botanists, and in ornithology the recent works of Coues and Ridgway have proved their value to the student. That the book might not reach a size too large for field or class use, I have made all descriptions very concise, with as few repetitions as possible. I have confined the generic characters to the analytical keys, using as a rule only such characters as are distinctive as well as descrip- tive. The need of condensation has caused the omission of synonymy, and of references to authorities except in special cases. In the first four editions of this work (1876, 1878, 1880, 1884), large use was made of artificial characters in the analyses of the genera. The use of such characters is often a help to quick identification of species, but with the disadvantage of hiding from the student the real char- acters on which classification is based. In the present edition, these artificial keys have been chiefly set aside, ii PREFACE TO THE FIFTH EDITION. and I have tried, with more or less of success, to set be- fore the student the essential characters of each group. The present edition is wholly re-written and it is printed from new stereotype plates. The order of ar- rangement is reversed, the lowest forms being placed first. The region covered by the Manual has been extended in the present edition so as to include, in addition, Mis- souri, Iowa, Minnesota, the Provinces of Canada, and the sea-coast from Nova Scotia to Cape Hatteras. The deep- sea fishes of this region are, however, omitted, as well as the tropical and semi-tropical forms which occasionally. drift northward in the Gulf Stream, without gaining any permanent place in the northern fauna. Several species of birds which have been once or twice taken in our limits, but which are merely accidental wanderers from the West or South or from Europe, have also been omitted. I have wished to include only those animals which really form a part of the fauna of the region in question. I have made free use of every available source of infor- mation, and I believe that the present state of our knowl- edge in this field is fairly represented. The arrangement of the fishes is essentially that of Jordan and Gilbert's "Synopsis of the Fishes of North America" (1883), and, almost exactly that of Jordan's "Catalogue of the Fishes of North America" (1885). The manuscript of the fresh water fishes, in the present edition, has been carefully re- vised by Prof. Charles H. Gilbert. The arrangement of the Batrachians and Reptiles is essentially that set forth in the various papers of Prof. Edward D. Cope. I have made use of Boulenger's Cata- logues of the Reptiles in the British Museum, and of the "Catalogue of North American Batrachia and Reptilia" by N. S. Davis and Frank L. Rice. The manuscripts of the Reptiles and Batrachians have been revised by Prof. O. P. Hay. PREFACE TO THE FIFTH EDITION. iii In the nomenclature and classification of the Birds, I have followed exactly the "Check List of North Ameri- can Birds," published by the American Ornithologists' Union. In the preparation of analytical keys to the genera of Birds, I have made large use of Ridgway's "Manual of North American Birds," and of Coues' "Key to North American Birds." In the arrangement of the Mammals, I have been guided primarily by Professor Baird's "History of North American Mammals." In the Rodentia, I have made use of the elaborate monographs of Dr. Elliott Coues and Dr. J. A. Allen; and in the other groups reviewed by Dr. Coues, I have adopted most of his conclusions. In the Cetaceans, I have used chiefly the papers of Mr. Frederick W. True and Prof. E. D. Cope, and both these naturalists have kindly furnished me with unpublished catalogues of the species recognized by them. In the preparation of the present edition I am also personally indebted for aid in various ways to Prof. Ed- ward D. Cope, Mr. Leonhard Stejneger, Prof. Charles H. Gilbert, Prof. Oliver P. Hay, Mr. Frederick W. True, Mr. Robert Ridgway, Mr. Amos W. Butler, Dr. J. Sterling Kingsley, Mr. Charles H. Bollman, Dr. Stephen A. Forbes, Mr. Barton W. Evermann, and others. I may again refer to the obligations acknowledged in the earlier edition, - especially to my indebtedness to Dr. Elliott Coues, Dr. Theodore Gill, Dr. G. Brown Goode, Dr. Tarleton H. Bean, Prof. Herbert E. Copeland, and Mr. Edward W. Nelson. DAVID S. JORDAN. BLOOMINGTON, INDIANA, June, 1888. THE VERTEBRATE ANIMALS • OF THE NORTHERN UNITED STATES. VERTEBRATA. (THE VERTEBRATES.) THE Vertebrates are, in popular language, "animals with a back-bone." They are distinguished from all other animals, says Professor Huxley, "by the circumstance that a transverse and vertical section of the body exhibits two cavities, completely sep- arated from one another by a partition. The dorsal cavity contains the cerebro-spinal nervous system; the ventral, the alimentary canal, the heart, and, usually, a double chain of ganglia, which passes under the name of the 'sympathetic.' A vertebrated ani- mal may be devoid of articulated limbs, and it never possesses more than two pairs. These are always provided with an internal skeleton, to which the muscles moving the limbs are attached.' Modern researches have shown that, besides the ordinary "back- boned animals," certain other creatures, formerly considered as Mollusks or Worms, are really degenerate forms of Vertebrates, and must be considered as members, or at least as associates, of this group. The resemblance to the other Vertebrates on the part of the forms in question is seen in their early or larval develop- ment, and scarcely at all in the adult condition. "Many of the species start in life with the promise of reaching a point high in the scale, but after a while they turn around, and, as one might say, pursue a downward course, which results in an adult which dis- plays but few resemblances to the other vertebrates." (Kingsley.) These are the Tunicates or Ascidians, forming the Class or Prov- ince of "Urochordata." The essential character of the Vertebrata, in the broad sense of the term, is now understood to be this: "The 6 VERTEBRATA. possession of a cellular cord, the 'notochord,' — which runs un- derneath the central nervous system, and which in the higher forms is surrounded by the permanent vertebral column and skull, and is largely obliterated by the development of these structures. So the term CHORDATA is frequently employed as synonymous with VER- TEBRATA in its wide sense." (R. R. Wright.) Without further discussion of the VERTEBRATA or "CHOR- DATA" as a whole, we may proceed to the account of the several subordinate groups or classes. The existing forms may first be divided into about six primary groups, which have been called "provinces " by Professor Huxley. These are (I) the Urochor- data, including the class Tunicata; (II) the Hemichordata or En- teropneusta; (III) the Cephalochordata, corresponding to the class Leptocardii; (IV) the Ichthyopsida, including the classes of Cyclo- stomi, Pisces, and Batrachia; (V) the Sauropsida, including the Reptilia and Aves; and finally (VI) the Mammalia, correspond- ing to the single class of the same name. The relations of these provinces and classes are shown in the following analysis taken, in part, from Dr. Gill's "Arrangement of the Families of Fishes." Only the more obvious characters are here mentioned. Others may be found in the more elaborate works on Comparative Anatomy. Analysis of the Classes of Chordata. a. Anterior end of the central nervous axis not dilated into a brain, and not surrounded by a protective capsule or skull. b. Notochord confined to the tail and usually present only in the tadpole- like larval stage of the animal (UROCHORDATA): adult animal not fish-like nor worm-like, its body invested with a tough envelope or "tunic." TUNICATA, A. bb. Notochord not confined to the tail, but extending forward to the anterior end of the body; sides of body with numerous gill slits which are persistent through life. d. Notochord developed in anterior end of body only (HEMICHOR- DATA): adult animal worm-like, without trace of fins; a long proboscis before the mouth. ENTEROPNEUSTA, B. dd. Notochord perfect, continued forward to a point before the mouth (CEPHALOCHORDATA): body elongate, lanceolate, somewhat fish- like in form, not worm-like nor enveloped in a "tunic"; middle line of body with rudimentary fins; no proboscis; the mouth slit- like, fringed with cirri. LEPTOCARDII, C. • • aa. Anterior end of the nervous axis dilated into a "brain," which is con- tained within a protective capsule, the "skull"; notochord not continued forwards beyond the pituitary body; heart developed and divided into at least two parts, an auricle and a ventricle. (CRA- NIOTA.) e. Respiration during part or the whole of life performed by means of gills; blood cold. (ICHTHYOPSIDA.) VERTEBRATA. 7 f. Skull imperfectly developed and without jaws; paired fins un- developed, with no shoulder girdle or pelvic elements; a single median nostril; gills purse-shaped; skin naked; skeleton car- CYCLOSTOMI, D. tilaginous. ff. Skull well developed, and with jaws; shoulder girdle and pelvic elements developed; nostrils not median. g. Limbs developed as rayed fins (rarely abortive); rayed fins nor- mally present on the median line of the body; respiration throughout life by means of gills; lungs usually not developed. PISCES, E. gg. Limbs not developed as rayed fins, but, if present, having the same skeletal elements as in the higher vertebrates; respiration in the adult chiefly accomplished by means of lungs, the gills usually not persistent; skin usually naked. BATRACHIA, F. ee. Respiration performed throughout life by means of lungs, the gill slits disappearing before birth. h. Mammary glands not present; diaphragm incomplete; a single occipital condyle; oviparous (or sometimes ovoviviparous), the young hatched from a rather large egg. (SAUROPSIDA.) i. Exoskeleton developed as scales or bony plates; blood cold; heart with three (rarely four) cavities. REPTILIA, G. ii. Exoskeleton developed as feathers; blood warm; heart with four cavities. AVES, H. hh. Mammary glands present; the young developed within the body from a minute egg (except in the Monotremata), and nourished for a time after birth by milk secreted in the mammary glands; exoskeleton developed as hair; two occipital condyles; dia- phragm complete; heart with four cavities; blood warm. MAMMALIA, I. Of these classes, the Tunicata (A) and the Enteropneusta (B) are excluded from the plan of the present work. The Tunicata are all marine forms, of small size, the larger species being familiarly known as "Sea Squirts," "Sea Peaches," and "Sea Pears"; but the most of them are without common names. A considerable number of species, representing several families, are found on our Atlantic coast. The Enteropneusta consist of the single genus Balanoglossus, a worm-like creature, of which two or three species are found on our coasts. They reach a length of six to twelve inches. They have been considered as worms having possible affinities with the Echinoderms, but the recent studies of Mr. William Bateson seem to show conclusively that their place is among the Chordata. Leaving these groups aside, we take up 8 LEPTOCARDII: CIRROSTOMI. —— I. CLASS C. LEPTOCARDII. (THE LANCELETS.) Skeleton membrano-cartilaginous; no brain; no skull; the noto- chord persistent and extending to front of body; no heart, its place being taken by pulsating sinuses; blood colorless; respiratory cav- ity confluent with cavity of abdomen; gill slits in great number; the water expelled from an abdominal pore in front of vent; no jaws; the mouth inferior, slit-like, with cirri on each side. (Gr. λεπτός, thin ; καρδία, heart.) ORDER I. CIRROSTOMI. The single order of this class contains but a single family. (Lat., cirrus, hair; Gr. σrópa, mouth.) FAMILY I. BRANCHIOSTOMATIDÆ. (THE LANCELETS.) Body elongate-lanceolate, compressed, naked, colorless, the fins represented by a low fold which extends along the back around the tail, past the vent, to the abdominal pore; eye rudimentary; liver a blind sac of the simple intestine. One genus, with 5 or 6 species; small, translucent creatures found imbedded in the sand on warm coasts. These animals are highly interesting to the anatomist as showing the vertebrate type in its simplest condition. 1. BRANCHIOSTOMA Costa. (Amphioxus Yarrell.) (βράγχια, gills ; στόμα, mouth.) 1.

The lampreys undergo a metamorphosis, the larva of all species being toothless and having the eyes rudimentary. The name Ammocœtes was formerly applied to the larval forms; originally, however, to that of A. branchialis. Genera 3 or 4, species about 15, chiefly of the fresh waters of temperate regions. They attach themselves to fishes, and feed by scraping off the flesh with their rasp-like teeth. a. Second dorsal joined to the caudal. b. Supraroral lamina (“maxillary tooth ") expanded laterally, forming a crescent-shaped plate, with a cusp at each end, and sometimes a median cusp; anterior lingual teeth serrate. AMMOCOTES, 3. • bb.

Color dark brown, usually mottled with blackish. L. 3 feet. N. Atlantic, S. to Va., ascending rivers to spawn, and permanently land-locked (var. uni- color, Dekay) in the lakes of W. and N. N. Y. The larva is blind, toothless, with a contracted mouth, in which the lower lip forms a lobe distinct from the upper. The eyes appear before the mouth is enlarged. (Eu.) In the spring the Lamprey ascends small brooks for the purpose of de- positing its spawn. They are then often found clinging to stones and clods of earth. Later in the season they disappear, and are seldom seen except when attached to some unlucky fish. They are rarely seen descending the stream, and "it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare's description of the sea floor." (Thoreau.) 12 PISCES. CLASS E. — PISCES. (THE FISHES.) A "fish" in the popular sense is a member of any one of the three classes of aquatic or fish-like vertebrates, the groups here designated as Leptocardii, Marsipobranchii, and Pisces. But the Lancelets and the Lampreys differ so widely from the other groups that we must exclude them from consideration as fishes. Many writers go still further and remove from the Pisces, the Sharks, Chimaras, and Dipnoans, but for our present purposes all these may be referred to the same class as the true fishes, or Teleosts. The Pisces or "Fishes " may then be defined as cold-blooded ver- tebrates adapted for life in the water, breathing by means of gills which are not purse-shaped, but attached to bony or cartilaginous gill arches; having the skull well developed and with a lower jaw; with the limbs present and developed as fins, or rarely wanting through atrophy; with shoulder girdle present, furcula-shaped, curved forward and with the sides connected below; with pelvic bones present; having the exoskeleton developed as scales or bony plates or horny appendages, sometimes obsolete, and with the me- dian line of body with one or more fins composed of cartilaginous rays connected by membrane. The existing representatives of the class Pisces may be conveniently divided into four subclasses: Selachii or Elasmobranchii, Holocephali, Teleostomi, and Dipnoi. The last group (Ceratodus, Lepidosiren) has well-developed lungs and the paired fins flipper-like. It forms a connecting link be- tween the Ganoidei and the Batrachia. As there are no North American species of Dipnoi, the group needs no further men- tion in this work. Subclasses of Pisces. a. Gills not free, being attached to the skin by the outer margin. Ova few and large, impregnated and sometimes developed internally: embryo with deciduous external gills; membrane bones of head undeveloped, except sometimes a rudimentary opercle; skeleton cartilaginous; skull without sutures; tail heterocercal; ventral fins abdominal; male with large intromittent organs or claspers attached to ventral fins; skin naked or covered with minute rough scales, sometimes with spines; no air-bladder; arterial bulb with three series of valves; intestine with a spiral valve; optic nerves united by a chiasma; cerebral hemispheres united. b. Gill openings slit-like, 5 to 7 in number; jaws distinct from the skull, joined to it by suspensory bones; no membrane bones; teeth distinct. (Sharks and Skates.). SELACHII, page 14. PISCES. 13 • bb. Gill opening single, leading to four gill clefts; jaws coalescent with the skull; a rudimentary opercle; teeth coalescent forming bony plates. (Chimæras.) HOLOCEPHALI, page 24. aa. Gills free, attached at base only to the gill arches; gill opening single on each side; eggs comparatively small and numerous; no claspers; mem- brane bones present on head; cerebral hemispheres not united. (True Fishes.). TELEOSTOMI, page 25. 14 SELACHII: SQUALI. — IV. SUBCLASS SELACHII. (THE SELACHIANS.) This group, sufficiently defined above, includes two orders, the Sharks and the Rays, marine fishes of large size, abundant in most seas. (Gr. σéλaxos, shark.) a. Gill openings lateral. aa. Gill openings ventral. • Orders of Selachii. ORDER IV. SQUALI. (THE SHARKS.) SQUALI, 4. RAIE, 5. The typical sharks are elongate in form, quite unlike the skates in appearance. Intermediate forms connect the two groups so closely that the position of the gill openings is the only constant character by which the two orders can be separated. (Lat., a shark, from Gr. yaλeós, allied to yaλéŋ, a weasel.) NOTE. - The Sharks are mostly fishes of the high seas, and any of the larger Atlantic species may stray to our coasts. Besides those here described, the following have been at least once taken within our limits: Echinorhinus spinosus (Gmelin), Cape Cod; Centrocyllium fabricii (Rein- hardt), off Gloucester; Centroscymnus cœlolepis (Bocage & Capello), Glou- cester; Pseudotriacis microdon (Capello), Long Island; Aprionodon isodon (Müller & Henle); Isogomphodon limbatus (Müller & Henle), Wood's Holl.

Ova small; no claspers. Heart developed, divided into an auricle, ventricle, and arterial bulb. Lungs imperfectly developed, or modi- fied to form a swim-bladder, or entirely absent. We here include under one head the Ganoids and the Teleosts. The former type is chiefly composed of extinct forms. While many of its representatives are extremely dissimilar to the bony fishes, there is a gradual series of transitions, and between the Halecomorphi of the Ganoids and the Isospondyli of the true Teleosts, the resemblance is much greater than that between the Halecomorphi and many other Ganoids The Ganoids are, in fact, the most generalized of the true fishes, those nearest the stock from which the Teleosts on the one hand, and the Dipnoi and Batrachia on the other, have sprung. The real value or rank of some of the current orders or suborders is still doubtful. (réλeos, perfect; στóμа, mouth.)

Pectoral fins pediculate, the basal bones reduced in number and elongate, the gills in their axils. PEDICULATI, XXIII. More than two hundred families are now recognized among the true fishes. The characters on which family divisions are based are usually internal, and often difficult for the beginner to ascer- tain. The boundaries and definitions of many families are also still uncertain. Instead, therefore, of giving a natural analysis under each order of the families included within it, I have thought it best to give instead an Artificial Key by which the student can recognize any of the families of True Fishes included in this work. For analytical keys showing, in some degree, the natural charac- ters, the student is referred to Jordan and Gilbert's Synopsis of the Fishes of North America. A repetition of these analytical tables would consume considerable space, and would not be of much aid to any but advanced students.

(THE GANOID FISHES.) The name Ganoidei was first used by Agassiz for those fishes which are armed with bony plates, instead of regular cycloid or ctenoid scales. Later, Johannes Müller, one of the greatest of systematic zoologists, restricted the group to those fishes which show more or less distinct reptilian or batrachian affinities, and especially affinities with the mailed fishes of the Devonian and Carboniferous ages. The group is a heterogeneous one, and one practically scarcely susceptible of definition. Some of the Ganoids are closely allied to the Teleosts; some approach the Dipnoi, and some again resemble the Holocephali. The existence of the solid optic chiasma, the presence of several valves in the arterial bulb, and of a more or less developed spiral valve in the rectum, distin- POLYODONTIDÆ. 33 XX. guish the living Ganoids from all Teleosts, but none of these char- acters can be verified in the extinct forms. It seems to us better not to regard the Ganoids as a separate class or subclass, but to unite them with the Teleosts. (yávos, splendor, from the enam- elled scales.) ORDER VII. SELACHOSTOMI.

SERIES TELEOSTEI. We now take up the series of Teleostei proper, or true Bony- fishes, a group comprising the great majority of existing fishes. It is apparently descended from the Ganoid type, the Nemato- gnathi being apparently allies or descendants of the Glaniostomi, and the Isospondyli of the Halecomorphi. As a whole, the Tele- ostei differ from the Ganoids in the more perfectly ossified skeleton, the less heterocercal tail, the degradation of the air-bladder and the arterial bulb, and in the simplicity of the optic chiasma. The Teleostei are divisible into two great groups, with rather ill-defined boundaries,—the Physostomi, or soft-rayed fishes, and the Physoclysti, or spiny-rayed. The members of the former group have throughout life a slender duct, by which the air-bladder is joined to the alimentary canal. In most cases the fin-rays are soft, the ventrals abdominal, the pectorals placed low, and the scales cycloid. Although the typical Physostomi differ in many ways from the more specialized Physoclysti, yet as we approach the junction of the two groups the subordinate differences disap- pear, leaving finally the presence of the air-duct in Physostomi as the only differential character. In view of this close relation of the two groups, several writers, following Professor Gill, have re- moved as separate orders various aberrant forms, leaving the bulk of both groups in one large order, Teleocephali, with numerous suborders. We prefer to regard most of these suborders as dis- tinct orders rather than to treat the heterogeneous group of Teleocephali as an "order." (Téλeos, perfect; dσréov, bone.) ORDER XI. NEMATOGNATHI. This order contains several families, which agree in having the subopercle wanting, the anterior vertebræ coalesced, and the max- illary reduced to the bony core of a long barbel. None of the order have scales. (vua, thread; yváłos, jaw.) 38 TELEOSTEI: NEMATOGNATHI. XI. FAMILY XXIV. SILURIDÆ. (THE CAT-FISHES.)

Air-bladder present, large. A vast family of more than 100 genera and 900 species, mostly of the rivers and swamps of warm regions, especially of South America and Africa. A few species are marine.

They stay near the bottom, moving slowly about with their barbels widely spread, watching for anything eat- able. They will take any kind of bait, from an angle-worm to a piece of a tin tomato- can, without coquetry, and they seldom fail to swallow the hook. They are very tenacious of life, "opening and shutting their mouths for half an hour after their heads have been cut off." They spawn in spring, and the old fishes lead the young in great schools near the shore, seemingly caring for them as the hen for her chickens.

Head naked, body usually scaly; margin of upper jaw formed by premaxillaries only; mouth toothless; barbels 2 to 4 (absent in most of our genera and not large in any); lower pharyngeal bones well developed, falciform, nearly parallel with the gill arches, each provided with one to three series of teeth in small number, rarely more than seven on each side; belly usually rounded, rarely com- pressed, never serrated; gill openings moderate, the membranes joined to the isthmus; no adipose fin; dorsal fin (in American species) short, with less than ten rays; air-bladder usually large, commonly divided into an anterior and a posterior lobe, rarely wanting; stomach without appendages, appearing as a simple en- largement of the intestines. Fishes of moderate or small size, inhabiting the fresh waters of the Old World and of North America. Genera about 200, species nearly 1,000; excessively abundant where found, both in individ- uals and in species, and from their great uniformity in size, form, and coloration constituting one of the most difficult groups in zoology in which to distinguish species. Ours are mostly of smaller size than those of the Old World, several of the larger European types being represented in America by Catostomoid forms. Our largest eastern species, Semotilus bullaris, rarely attains a weight of three or four pounds, and a length of nearly eighteen inches. The smallest species of Notropis scarcely reach a length of two inches. The spring or breeding dress of the male fishes is often peculiar. The top of the head, and often the fins, snout, or other portions of the body, are covered with small tubercles, outgrowths from the 4 50 XII. TELEOSTEI: EVENTOGNATHI. epidermis. The fins and other parts are often charged with pig- ment, the usual color being red, but sometimes satin-white, yellow- ish, or black. NOTE. -Young Cyprinidæ are usually more slender than adults of the same species, and the eye is always much larger; they also frequently show a black lateral stripe and caudal spot, which the adults may not possess. In the following descriptions, the rudimentary rays of dorsal and anal are not counted. The fins and scales are often, especially in specimens living in small brooks, covered with round black specks, parasitic plants. These should not be mistaken for true color-markings. No progress can be made in the study of these fish without careful attention to the teeth, as the genera are largely based on dental characters. The pharyngeal bones in the smaller species can be removed by inserting a pin (or, better, a small hook) through the gill opening, under the shoulder girdle. The teeth should be carefully cleaned with a tooth-brush, or, better, a jet of water, and when dry may be examined by any small lens. In most cases a principal row of four or five larger teeth will be found, in front of which is a set of one or two smaller ones. The two sides are usually, but not always, symmetrical. Thus, "teeth 2, 4-5, 1," indicate two rows of teeth on each side, on the one side four in the principal row and two in the lesser, on the other side five in the main row and one in the other. "Teeth 4-4" indi- cates a single row of four on each pharyngeal bone, and so on. In the Leuciscine genera, these teeth, or the principal ones, are "rapta- torial," that is, hooked inward at the tips. A grinding or masticatory surface is an excavated space or groove, usually at the base of the hook. Sometimes the grinding surface is very narrow and confined to one or two teeth. Some- times a bevelled or flattened edge looks so much like a grinding surface as to mislead a superficial observer. In some cases, the edge of the tooth is crenate or serrate. Besides the native species here mentioned, representatives of two other genera have been introduced from Europe, and have become inhabitants of some eastern streams. These are Cyprinus Linnæus, and Carassius Nilsson. The first is distinguished by the very long dorsal, which, like the anal, is pre- ceded by a strong spine, serrated behind. About the mouth are four long barbels, and the teeth are molar, 1, 3–3, 1. This genus is represented by the Carp (Cyprinus carpio L.). The carp is normally covered with large scales. In domestication, however, variations have arisen, prominent ones being the "Leather Carp," naked, and the "Mirror Carp," with a few series of very large scales. Carassius Nilsson differs from Cyprinus, chiefly in the absence of barbels, and in having the teeth compressed, 4-4. The Gold-fish (Carassius auratus L.) is originally olivaceous, but only the orange-red variety is valued for aquaria. Both Carassius and Cyprinus are native in China. a.

(Hybopsis tuditanus Cope; Alburnops taurocephalus Hay.) (Lat., watchful.) 56. NOTROPIS Rafinesque. (AMERICAN MINNOWS.) (MINNILUS Rafinesque, etc., etc.) (As now understood, this genus contains upwards of a hundred species of small Cyprinoids, all of them confined to the waters of E. N. A. They are feeble fishes, of rather low organization, none of them of any value as food to man, but of great importance as food for the larger predatory fishes. The species are highly vari- able, readily affected by surrounding conditions, while the per- manently distinctive characters are few. The identification of species in this group is therefore very difficult, and in the case of young specimens often impossible. The following analysis must be used with caution, as all characters are subject to occasional or individual variations.) (vŵтos, back; тρómis, keel; but the back is not keeled. Rafinesque's types had been shrivelled by drying.) a. Teeth 4, 4, or 1, 4-4, 0, or 1, 4-4, 1 (sometimes 1, 4-4, 2 in N. hudsonius). b.

They will be hatched by machinery and raised in ponds and fattened on chopped liver, and grow flabby and lose their spots. The trout of the restaurant will not cease to be. He is no more like the trout of the wild river than the fat and songless reed-bird is like the bobolink. Gross feeding and easy pond life enervates and depraves him. The trout that the children will know only by legend is the gold-sprinkled living arrow of the White-water, able to zigzag up the cataract, able to loiter in the rapids, whose dainty meat is the glancing butterfly."

HAPLOMI. (THE PIKE-LIKE FISHES.) This order differs from the other soft-rayed fishes, chiefly in the simpler structure of the shoulder girdle, which lacks the præcoracoid arch. There is never an adipose dorsal; the dorsal is posterior in position and the head is depressed and usually more or less scaly. The pseudobranchiæ are wanting or glandular. The group is made up chiefly of fresh-water species. (árλóos, simple; wμos, shoulder.) FAMILY XXXVI. AMBLYOPSIDÆ FISHES.)

"If the Amblyopses be not alarmed, they come to the surface to feed, and swim in full sight, like white aquatic ghosts. They are then easily taken by the hand or net if perfect silence be preserved, for they are unconscious of the presence of an enemy except through the sense of hearing. This sense is however very acute; for at any noise, they turn suddenly and hide beneath stones at the bottom. They take much of their food near the surface, as the life of the depths is apparently very sparse. This habit is rendered very easy by the structure of the fish, for the mouth is directed upwards, and the head is very flat above, thus allowing the mouth to be at the surface." (Cope.) 86.

One genus, with 5 species, one in the fresh waters of both continents, the rest all American. All are noted for their voracity, “mere machines for the assimilation of other organisms." The flesh is white, flaky, and excellent. The Pike is "a solemn stately ruminant fish, lurking under the shadow of a lily-pad at noon, with still, circumspect, voracious eye, motionless as a jewel set in water, or moving slowly along to take up its position; darting from time to time at such unlucky fish or frog or insect as comes within its range, and swallowing it at a gulp. Sometimes a striped snake, bound for greener meadows across the stream, ends its undulatory progress in the same receptacle." (Thoreau.) 94. ESOX (Artedi) Linnæus. (An old name of the Pike). a.

A magni- ficent fish, one of the largest in fresh waters. Great Lake region and N. W.; occasional in the Ohio valley. "A long, slim, strong, and swift fish, in every way fitted for the life it leads, that of a dauntless marauder." (Hallock.) (The Indian name.) ORDER XV. APODES. (THE EELS.) Scapular arch free from the cranium; no præcoracoid arch; body much elongate, with many vertebræ; no ventral fins; maxil- laries and premaxillaries united with other bones or else wanting; pharyngeal and opercular bones more or less deficient; no fin spines; gill openings narrow; no pseudobranchiæ; scales minute or wanting. A large group, as yet of uncertain boundaries, com- posed of degenerate Physostomi, its origin and relationship as yet, however, uncertain. Most of the Eels are tropical and marine, and many belong to the deep seas. Numerous genera and species not here included occur in the deep waters off our coast. (a, privative; ToÚs, foot.) FAMILY XL. ANGUILLIDE. (THE TRUE EELS.)

Sexual organs in- conspicuous. One genus with four or more species, crawling in the mud and ooze of brackish and fresh waters of most regions, absent on the Pacific coast of America. They are among the most vora- cious of fishes. “On their hunting excursions, they overturn alike huge and small stones, beneath which they find species of shrimp and cray-fish, of which they are excessively fond. Their noses are poked into every imaginable hole in their search for food, to the terror of innumerable small fishes." (W. H. Ballou.) The eels often move for a considerable distance on land, in damp grass. High waterfalls, dams, and other obstructions are often passed in this way. It is thought that eels spawn only in the sea, and that the female spawns once and then dies. The females are larger than the males, paler in color, with smaller eyes and higher fins. 95. ANGUILLA Thunberg. 218. A. anguilla (L.). EEL. Brown, more or less tinged with yellowish. Head 81. L. 40. N. Atlantic, from Maine to Brazil, ascending all streams; found throughout Mississippi valley, never in the open sea. The American Eel (var. rostrata Le Sueur) has the distance from front of D. to front of A. a little less than head; in the European form this is a little greater, the D. being a little farther back in the former.

Eels closely related to the Anguillidæ, but without scales, and with the ovaries in the female evident, and with comparatively large eggs similar to those of fishes generally. D. commencing not far behind head. Genera 3 or 4; species about 10, all strictly marine. Leptocephalus morrisi Gmelin, a translucent, ribbon-shaped creature, with very small head, and no generative organs, is occa- sionally taken on our coasts. This is thought to be a stage of ar- rested development of the young of Echelus, a larval form which goes on increasing in size without ever reaching the characters of the perfect animal. a.

EXOCETIDÆ. 91 XLII. 219. E. conger (L.). CONGER EEL. Cleft of mouth reaching beyond middle of the large eye; dark brown above, paler below. D. and A. usually pale, with broad, black margin; P. dusky, pale- edged; pores of lateral line whitish; body sometimes wholly black. L. 6 feet. Open sea, not rare on our coast. (Eu.) (yóyypos, Conger, the ancient name.) SERIES PHYSOCLYSTI. We now begin the division of fishes in which the air-bladder in the adult loses all connection with the alimentary canal. This character in itself is of slight importance, but it is associated with gradual modifications in other respects, of such character that the typical Physoclyst is quite unlike the average Physostome. Most of the Physoclysts have spines in some of the fins; the ven- tral fins are normally thoracic, each with a spine and five rays, while the pectorals are inserted high. But there are many excep- tions to each of these characters. We commence the series with the forms most closely related to the Haplomi and other soft-rayed forms. (puoa, bladder; Kλelorós, closed.) ORDER XVI. SYNENTOGNATHI. (THE SYNENTOGNA- THOUS FISHES.) Physoclistous fishes without spines in the fins, with the ventrals abdominal and the lower pharyngeals fully united. This peculiar transitional group contains a single family divided by osteological characters into two strongly marked groups, called families by Dr. Gill. These are the Belonida and the true Exocœtidæ or Scom- beresocida. (oúv, together; evrós, within; yválos, jaw.) FAMILY XLII. EXOCETIDÆ. (THE NEEDLE-FISHES. FLYING-FISHES.)

TELEOSTEI: SYNENTOGNATHI. eighth of a mile, rarely rising more than 3 or 4 feet. Their move- ments in the water are extremely rapid; the sole source of motive power is the action of the strong tail while in the water. No force is acquired while the fish is in the air. On rising from the water, the movements of the tail are continued until the whole body is out of the water. While the tail is in motion, the pectorals seem to be in a state of rapid vibration, but this is apparent only, due to the resistance of the air to the motions of the animal. While the tail is in the water, the ventrals are folded. When the action of the tail ceases, the pectorals and ventrals are spread and held at rest. They are not used as wings, but act rather as parachutes to hold the body in the air. When the fish begins to fall, the tail touches the water, when its motion again begins, and with it the apparent motion of the pectorals. It is thus enabled to resume its flight, which it finishes finally with a splash. While in the air it resem- bles a large dragon-fly. The motion is very swift, at first in a straight line, but later deflected into a curve. The motion has no relation to the direction of the wind. When a vessel is passing. through a school of these fishes, they spring up before it, moving in all directions, as grasshoppers in a meadow.¹ The young of different species often have long fleshy barbels at tip of the lower jaw. These are lost with age. They were formerly placed in a separate "genus," Cypselurus Swainson.

The Perch-like fishes have usually larger and rougher scales than the Scombroids, and the development of the spinous armature of the fins is in general more pronounced. We begin with one of the most aberrant forms, the small FAMILY LX. APHREDODERIDÆ. (THE PIRATE PERCHES.)

This group comprises a great variety of forms, and it has been usually divided into 10 to 16 genera. It is, however, impossible to maintain most of these subordinate groups as genera on account of intergradations of all sorts. There is no considerable variation in the osteology ¹ of the species, except in regard to the numbers of the vertebræ. The group is apparently one of comparatively recent origin, and the differential characters do not seem to have become very firmly fixed. On the other hand, the extremes of the group (as E. pellucidum or E. microperca) have diverged very far from their perch-like ancestors. The relations of the Darters to the Perches have been aptly ex- pressed by Dr. Stephen A. Forbes: "Given a supply of certain kinds of food nearly inaccessible to the ordinary fish, it is to be ex- pected that some fishes will become especially fitted for its utiliza- 1 For an account of the osteology of this group, see Jordan & Eigenmann, Proc.

Thus Etheostoma is to be explained by the hypothesis of the progressive adaptation of the young of certain Percina to a peculiar place of refuge and a peculiarly situated food supply. These are the mountaineers among fishes. Forced from the popu- lous and fertile valleys of the river beds and lake bottoms, they have taken refuge from their enemies in the rocky highlands, where the free waters play in ceaseless torrents, and there they have wrested from stubborn nature a meagre living. Although diminished in size by their constant struggle with the elements, they have de- veloped an activity and hardihood, a vigor of life and a glow of high color, almost unknown among the easier livers of the lower lands. Notwithstanding their trivial size, they do not seem to be dwarfed so much as concentrated fishes." Their colors are often very brilliant, the males of some species being among the most brilliant fishes known. The sexes are usually unlike; the females being generally dull and speckled. They usually prefer clear running water, where they lie on the bottom concealed under stones, darting, when frightened or hungry, with great velocity for a short distance, by a movement of the large pec- torals, then stopping as suddenly. They rarely leave the bottom, and are never seen suspended in the water. A few species prefer a sandy bottom, where they lie buried in the sand, with only the eyes visible. The Darters feed chiefly on the larva of Diptera. The largest reach a length of 8 inches, but the average is about 2 inches. (The name Etheostoma is said by Rafinesque to mean "various mouths" (repos, various; σróμa, mouth?), the three species known to him caprodes, blennioides, and flabellare, differing much in this respect.) a.

(Lat., throat, the fish being called "Petite-Gueule” in W. I.) PHARYNGOGNATHI. This family closes the series of fishes hav- ing Percoid affinities. We now pass to the group or suborder PHARYNGOGNATHI, those forms allied to the Lubroids, and distin- guished especially by the complete union of the lower pharyngeal bones. Of these, the typical forms, Labridæ, Pomacentrida have the gills reduced, 3 in number; the last gill slit wanting or nearly So. Some of them (Pomacentrida, Cichlida) differ from other spiny-rayed fishes in having but one nostril on each side; still others (Embiotocida) are viviparous. The Pharyngognathi being chiefly tropical are scantily represented within our limits. FAMILY LXX. LABRIDE. (THE WRASSES.) Body oblong, covered with cycloid scales; lateral line usually in- terrupted or angularly bent. Mouth terminal, protractile; the teeth of the jaws generally strong; no teeth on vomer or palatines; maxillaries simple, slipping under membranous edge of preorbital; lower pharyngeals solidly united, with blunt teeth; D. continuous, with 8 to 20 spines, the number greatest in Northern forms, which, as usual among fishes, have also an increased number of vertebræ ; anal spines 2 to 6, usually 3. V. normal. Pseudobranchiæ present. Gills 3½, usually no slit behind the last; nostrils double; air-bladder present. Genera 65; species 450, chiefly of the tropical seas. Many of them are brilliantly colored and some are valued as food. The teeth are adapted for the crushing of shells. (Labrus, an old name from labrum, lip.) a. Vertebræ in increased number, 30 to 38; dorsal spines 16 to 20; teeth in jaws distinct, the anterior canine; no posterior canines; lateral line con- tinuous; lips thick. (Labrinæ.) b. Preopercle serrate; cheeks and opercles scaly; teeth in more than two series, the outer enlarged. CTENOLABRUS, 182. bb.

The rest of the Pharyngognathi are beyond our limits, as are also the great bulk of the next group, or suborder, the Squamipennes, or Epelasmia (Cope). Of these only a single species comes N. of Va. In this group the post-temporal is simple, and the upper pharyngeals reduced to thin laminæ. The group includes the Chaetodontidæ, Acanthuridæ, Teuthididæ, and the small FAMILY LXXI. EPHIPPIDÆ. (THE ANGEL-FISHES.) Body compressed and elevated; scales ctenoid densely covering the body and the soft parts of the vertical fins; lateral line present. Mouth small, terminal, with bands of setiform (tooth-brush-like) teeth; premaxillary protractile; maxillary simple, partly slipping under preorbital; gill membranes broadly attached to the isthmus; gill rakers very short; pseudobranchiæ present. Dorsal deeply notched, with 8 to 11 spines, the soft part very high, as is also the soft anal; A. spines 3 or 4; C. subtruncate; P. short; V. normal. Air-bladder large.

Y.; a good food-fish. (An old name, meaning blacksmith.) CATAPHRACTI. We next pass to the group of Cataphracti or Cottoid fishes, an assemblage of families, characterized as a whole by the development of a "suborbital stay,” a bony process extend- ing from the suborbital ring backward across the cheeks to or to- wards the preopercle. In the extreme forms (Agonidæ, etc.), the SCORPÆNIDÆ. 147 - LXXII. cheek is wholly mailed. In others, as Cyclopterus, this stay is little conspicuous. The Cataphracti agree with the Scyphobranchii in having the third upper pharyngeal large, basin-shaped, but they differ much among themselves, the Hexagrammide and Scorpœnidæ resembling the Perciform fishes, while some of the others are widely aberrant. FAMILY LXXII. SCORPÆNIDÆ. (THE ROCK-FISHES.) Body oblong, robust, usually covered with ctenoid scales; lateral line present. Head large, with spinous ridges above; opercle with two spinous processes; preopercle with five. Mouth large, the jaws with villiform teeth; premaxillaries protractile; maxillaries broad, simple, not sheathed by preorbital; bony suborbital stay present, usually covered by skin and usually not reaching preopercle. Gill membranes free and separate. Gills 33, with no slit behind the last. V. normal, I, ō. D. continuous, with 8 to 16 strong spines. Arctic species have more spines and more vertebræ than tropical species. Vertebræ 24 to 32; A. short, with 3 spines; P. broad. Pseudo- branchiæ and air-bladder large. Genera 20; species 200. Carniv- orous fishes living about rocks in all seas, often at considerable depths, especially abundant about Cal. and Japan. Non-migratory; excellent as food, and usually red in color. Most are viviparous, the young inch long when born. (σкоρπíos, scorpion.) a. Dorsal spines 15; vertebræ 12+ 1931; palatine teeth present; head not very rough above. SEBASTES, 185. 185.

Its essen- tial feature is in the unsymmetrical character of the bones of the head. The head is twisted about, so that both eyes are on the same side. The body is compressed, and the side without eyes is habit- ually kept lowermost. The blind side is usually colorless. The very 164 XXI. TELEOSTEI: HETEROSOMATA. young are symmetrical, one eye on each side, the body is translu- cent and the fish is vertical in the water. The processes by which the eye of the lower side becomes transferred through or over the head to the other side are very curious and interesting. There is but one family.

No scales. This singular group is probably a modified off-shoot of the Haplo- doci (Batrachida) or of some similar form. It may fairly be placed at the end of the fish-series, as having gone farther in its diver- gence from the original fish-stock than any other of the groups called "orders" among fishes. It is not however in any proper sense the "highest" of the fishes, for some of its peculiarities may be due to degradation. Still less is it the order most closely related to the higher vertebrates. Most of the Pediculati belong to the tropics or to the deep sea. (Lat., pediculatus, provided with a little foot or peduncle.) FAMILY XCIV. MALTHIDE. (THE BAT-FISHES.)

With this monstrous creature, unexcelled for pure ugliness in the class to which it belongs, we may close the long series of fishes. LOPHIIDÆ. - XCVI. 173 Next come the Batrachians, animals bearing close relations to the "central stem" of the fishes, now represented by the Dipnoi. They are decidedly fish-like in their early conditions, but this stage is ultimately outgrown. "The undivided cartilaginous coracoid of Polyterus (a Dipnoan) has a tubercle articulating with diverging rods; in the one we have the rudiment of the humerus, in the other the representatives of the ulna and radius, while the undif- ferentiated cartilage between the diverging rods is material for the carpal bones, and in bones radiating from that cartilage are the homologues of the metacarpals. The attempts of a primitive ani- mal of such a type to travel on land might develop the fore-limb, and a hind one would follow in sympathy with the other. Then we would have the first of the quadruped vertebrates," the Batrachians. (Gill.) NOTE.- Page 47. The RED-HORSE or WHITE SUCKER of the Chesa- peake region has the anterior rays of the dorsal elevated, the outline of the fin decidedly concave. It is perhaps a distinct species from the common Red-Horse of the West and South described in the text. It may stand as 81. Moxostoma macrolepidotum (Le Sueur), and the Western form, N. Y. to Dak. and Ga., as 81 (b). M. duquesnei (Le Sueur). 174 BATRACHIA. CLASS F. BATRACHIA. (THE BATRACHIANS.) Cold-blooded vertebrates, intermediate between the fishes and the reptiles. They differ from the fishes chiefly in the absence of rayed fins, the limbs being usually developed and functional with the skeletal elements of the limbs of reptiles, and in the reduction or absence of the various bones of the branchial, opercular and sus- pensory systems. The Batrachians undergo a more or less complete metamorphosis; the young ("tadpoles ") being fish-like and more or less aquatic, breathing by means of external gills. These differ from the gills of fishes in standing on fleshy processes of the branchial bones and not on the bones themselves. In the tadpole, the tail is provided with a more or less distinct fin-like membrane, which usually dis- appears with age. Later in life, lungs are developed, and in most cases the gills disappear. Skin mostly naked and moist, used to some extent as an organ of respiration. Heart with two auricles and a single ventricle. Reproduction by means of eggs which are of comparatively small size, without hard shell. These are deposited in water or in damp places. In one salamander the young are born alive. Pro- fessor Cope recognizes nine orders of Batrachians, four of these being extinct. (Bárpaxos, frog.) Orders of Batrachia. a. Body lengthened, with a distinct tail throughout life; hind limbs, if present, not especially enlarged. b.

BATRACHIA: URODELA. This group is divided by Cope into 7 families, all but one of these (Salamandrida) being represented in our fauna. These families are based chiefly on technical characters, most of which can be ascertained only by a careful study of the osteology. "It may be stated as characteristic of the Batrachia in general that their char- acters cannot be determined without a study of the skeleton." (Cope.) (ovpá, tail; dîλos, visible.)

(THE REPTILES.) THE Reptiles are cold-blooded air-breathing vertebrates, usually scaly or covered with bony plates, never with feathers or hair. The limbs when present are usually adapted for walking, sometimes for swimming. There is an incomplete double circulation of the blood; the septum between the two ventricles being usually want- ing or imperfect. There is no metamorphosis after leaving the egg, and the eggs are large and mostly provided with a leathery skin. The skeleton is usually firm, and the nervous system is better developed than in the preceding groups. There are various other anatomical and embryological peculiarities of the Reptiles, too numerous to be noticed here. We may say however that the Reptiles are obviously distinguished from the Birds by the absence of feathers, and from the Batrachians by the presence of scales, and by the absence of gills after leaving the egg. The extinct forms of Reptiles are numerous, and their close relation with the earlier birds show the propriety of uniting the two classes in a single group, Sauropsida. The three orders represented in our fauna are well distinguished from each other. A fourth (Croco- DILIA) is represented by two species (Alligator mississippiensis Daudin, and the rare Crocodilus americanus Seba,) in the lowlands of the South. Orders of Reptilia. a. Body covered with imbricated scales; vent a cross-slit; bones of skull separate; jaws with teeth; dorsal vertebræ and ribs movable. → b. Mouth very dilatable; bones of mandible (and of head generally) united by ligaments; limbs wanting or represented by short spurs on sides of vent; no shoulder girdle; no eyelids; no tympanum. OPHIDIA, XXVIII. bb. Mouth not dilatable; bones of mandible united by a bony suture in front; limbs 4 (rarely obsolete); shoulder girdle present; eyelids and tympanum usually evident. LACERTILIA, XXIX. • • aa. Body short, depressed, enclosed between two bony or cartilaginous shields (carapace; plastron), from which the head, limbs, and tail may be pro- truded; jaws with a horny shield and no teeth; vent roundish or longi- tudinal, plaited. . TESTUDINATA, XXX. ORDER XXVIII. OPHIDIA. (THE SERPENTS.) Reptiles with elongate, terete bodies, obsolete limbs, and with an epidermal covering of imbricated scales, which is shed as a whole and replaced at regular intervals; the mouth very dilatable; the 188 XXVIII. REPTILIA: OPHIDIA. bones of both jaws and of the palato-pterygoid arch freely movable, united by ligaments only. Limbs wanting; the shoulder girdle wanting; the pelvic girdle usually so, rarely rudimentary, and with the hinder limbs represented by small spurs on the sides of the vent; vent a transverse slit; tongue forked, capable of protrusion ; no eyelids, nor external ears. Various anatomical characters dis- tinguish the snakes, but the elongated form and absence of limbs separate them at once from all our other vertebrates, excepting the lizard Ophiosaurus, and this is not in any other respect, snake-like. (opis, snake.) Families of Ophidia. a. Maxillary horizontal, not excavated; no trace of hinder limbs; no deep pit between eye and nostril; poison fangs wanting, or if present, per- manently erect. • b. Upper jaw with solid teeth only; no grooved nor perforated fangs. (Non- venomous.). COLUBRIDÆ, 110. bb. Upper jaw with a permanently erect perforated fang in front. (Somewhat venomous.) ELAPIDE, 111. aa. Maxillary vertical; upper jaws in front with large, erectile perforated fangs; fangs not grooved in front; a deep pit on each side behind nostril, partly occupying the excavated maxillary. (Venomous.) CROTALIDE, 112. FAMILY CX. COLUBRIDÆ. (THE COLUBRINE SNAKES.) Both jaws fully provided with teeth, which are conical and not grooved; head covered with shields; no poison fangs; no spur-like appendages to vent; belly covered with broad band-like plates (ventral plates or gastrosteges); tail conical, tapering; sub-caudal plates (urosteges) arranged in pairs. A very large family comprising 225 genera, and upwards of 700 species, found in nearly every part of the world, but most abundant in warm regions. They differ from the Elapida in the want of erect poison fangs; from the Crotalidæ, in having both jaws fully provided with teeth, and in the absence of erectile poison fangs; and from the Boida and their relatives in the want of the spur-like ru- dimentary posterior limbs. a. Head conic, not distinct from the body, which is cylindric and rather rigid. (Calamariinæ.) b. None of the teeth grooved; scales not keeled; anal plate bifid; inter- nasals 2. c. Prefrontals 2. d.

Dorsal scales all or part of them keeled; head rather long. 1 These three sub-families are so vaguely bounded that I cannot use their distinc- tive characters in the key. Professor Cope gives the following definitions :- Homalopsina. (Genera 273 to 278.) "Hypapophyses spinous to caudal region; an- terior teeth not enlarged; body not slender; head distinct." Colubrinæ. (Genera 279 to 283.) Head more distinct and elongate; body and tail longer; teeth entire, not longer in front. Coronellinæ. (Genera 284 to 288.)

Reptiles with the body enclosed between 2 more or less developed bony shields, which are usually covered by horny epidermal plates, but sometimes by a leathery skin. Upper shield (carapace) and lower shield (plastron) more or less united along the sides. Neck and tail the only flexible parts of the spinal column; these, together with the legs, usually retractile within the box made by the two shields. The bony part of the carapace is formed by the dorsal and sacral vertebræ, and the ribs co-ossified with a series of overlying bony plates, usually accompanied by a marginal row. The dorsal vertebræ have their ends flattened and immovably united by cartilage, and all of them, except the first and last, have their neural spines flattened horizontally so as to form the median line of plates. On either side of this series is a single row of ossi- fied dermal plates overlying the ribs and corresponding in number to the developed ribs, of which there are usually 8 pairs. No true sternum; plastron consisting of membrane bones, of which there are usually 9 pieces,-4 pairs and a single symmetrical median 204 XXX. REPTILIA: TESTUDINATA. piece. The osseous plates, both above and below, correspond neither in number nor position with the overlying dermal plates. The skull is more compact than that of the other reptiles. There are no teeth, but the jaws are encased in horny sheaths, usually with sharp cutting edges; the eye is furnished with two lids and a nictitating membrane as in the birds; the tympanic membrane is always present, although sometimes hidden by the skin. Respira- tion is effected by swallowing air. (Lat., testudo, tortoise.) Families of Testudinata. a.

Passing over the order CROCODILIA, the highest in development among the recent reptiles, an order having no representatives within our limits, we take up next a group originally an offshoot from the Reptilian series, but now, if only living forms were taken into consideration, one of the most sharply defined of the classes of Vertebrata, the Birds. 212 AVES. CLASS H.-AVES. (THE BIRDS.) A Bird may be defined as an air-breathing vertebrate with a covering of feathers; warm blood; a complete double circulation; the two anterior limbs (wings) adapted for flying or swimming, the two posterior limbs (legs) adapted for walking or swimming; respi- ration never effected by gills or branchiæ, but, after leaving the egg, by lungs, which are connected with air cavities in various parts of the body. Reproduction by eggs, which are fertilized within the body and hatched externally, either by incubation or exposure to the heat of the sun; the shell calcareous, hard and brittle. Much more might be added, but the obvious character is this: All Birds have feathers, and no other animal has feathers, or, as Stejneger puts it, “A bird is known by its feathers." There is probably no other character of importance which distinguishes birds living and extinct as a whole, from the Reptilia. The classification of this group, as of most others, is still in an unsettled condition. Strictly speaking, the existing members of the class are so closely related that they might, with propriety, be combined into one order, which, by Professor Gill, has been named EURHIPIDURÆ. At present, however, the term "order" may be applied to the groups so designated below, without thereby imply- ing any structural differences such as separate the "orders of Reptiles or even of Fishes. The Eurhipiduræ are made a sub- class by Stejneger, while Coues divides them into two "sub-classes,” the Ratitæ (Ostriches, etc.), and the Carinatæ. To the Carinatæ, characterized by the keeled sternum and more or less developed wings, all American birds belong. (Lat., avis, bird.) "" The "orders" of the Carinate Birds, as now adopted, are rather temporary, pending investigation of certain groups. They are also in a degree conventional, some of them being admittedly unnatural in their composition, while none of them represent any such struc- tural differences or differences of such long standing in time as those which characterize the orders of Mammals or Reptiles, or most of the orders of Fishes. For reasons which have been elsewhere given, I follow in this work without exception the classification, sequence, and nomenclature adopted by the American Ornitholo- gists' Union. A system in some respects more in accord with • AVES. 213 modern investigations is outlined by Stejneger in the Standard Natural History. The following largely artificial key to the Orders recognized by the Am. Orn. Assoc. is partly arranged from the key given by Ridgway (Man. N. Am. Birds). Orders of Aves. A. STERNUM KEELED: (CARINATÆ). a. Feet totipalmate, the hind toe well developed and all four toes full-webbed; palate desmognathous. STEGANOPODES, XXXIV. • aa. Feet not totipalmate, the hind toe, if present, not connected with the others. b. Feet palmate, the anterior toes full-webbed or nearly so (or lobate, with the claws broad, nail-like) (tarsus not specially elongate, and the tibia little if any naked below, in our species). c. Bill not lamellate, its cutting edge entire; schizognathous. (Cecomor- pha Huxley, Stejneger.) d. Legs inserted far behind the middle of the body, which in standing position is more or less erect. PYGOPODES, XXXI. dd. Legs not inserted far behind the middle of the body, which in a standing position has its axis nearly horizontal; wings usually very long. e. Nostrils not tubular. ee. Nostrils tubular. • • LONGIPENNES, XXXII. TUBINARES, XXXIII. cc. Bill lamellate, its cutting edges serrated or fringed. ANSERES, XXXV. bb.

Waders, tibia usually more or less naked below; the tarsus more or less elongate. g. Hind toes well developed and usually inserted on same level as anterior toes, the claws never excessively lengthened; loral or orbital regions or both naked; desmognathous. HERODIONES, XXXVI. gg.

MACROCHIRES, XLV. mm. Hind claw at least as long as middle claw; toes always 3 in front, 1 behind, cleft to the base or with the basal joints only immov- ably coherent; palate ægithognathous.. ORDER XXXI. PYGOPODES. PASSERES, XLVI. PYGOPODES. (THE DIVING BIRDS.) Feet palmate or lobate; tibia feathered, included in the skin nearly to the heel-joint, hence the legs set far back, so that the birds are scarcely able to walk at all on land; hind toe small and ele- vated, or wanting; nostrils developed; bill horny, not lamellate or serrate; no gular pouch; palate schizognathous; wings very short; tail very short or rudimentary. This is apparently not a natural order. Stejneger (following Huxley) unites the Pygopodes, Longipennes and Tubinares in one order, Cecomorpha. He remarks: "The fact is that not only are the gulls very nearly related to the auks, but their affinities with the Gralla through the plovers are unmistakable. On the other hand, the grebes seem to be only distantly related to the other 'Pygopodes' and the puffins and albatrosses similarly so to the Longipennes or gulls." The Pygopodes are water birds, expert divers, feeding chiefly on fishes. (vy, rump; Toús, foot.) Families of Pygopodes. a. Tail feathers wanting; anterior toes lobed, the claws very broad, flat, rounded at tip, resembling human nails. aa. Tail feathers developed, but short. b. Toes 4; the hind toe present. bb.

Desmognathous swimmers with the basipterygoids more or less. developed and the feet not totipalmate; bill lamellate; no gular pouch. Feet 4-toed, palmate; hind toe small, elevated. Legs short. This order (often called Lamellirostres, associated with the Flamingoes, etc., to form the Chenomorphæ of Huxley and Stejne- ger) "opens the series of desmognathous birds, which are char- acterized by having the palatal bones united across the middle either directly or by the intermediation of ossifications in the nasal septum." (Stejneger.) This familiar order contains nearly all the Water-fowl which are valued in domestication or as game birds. As here understood, the Anseres comprise but a single family, the Phoenicopteridæ or Flamingoes, wading birds with a duck's bill, being placed in a distinct order Odontoglossa, by the American Ornithologists' Union.

This division of the old order of Gralla includes the allies of the Plover and Snipe, as distinguished from the nearly related Cranes and Rails on the one hand and the remotely related Herons and Ibises on the other. Some of the external characters of the group are the following. Tibia more or less naked below; legs long; hind toe free and elevated, often wanting. Head glo- bose, abruptly sloping to the base of the bill; completely feathered (except in the male of Pavoncella); gape short; bill weak, flexible, more or less soft-skinned and sensitive at tip in most cases, adapted for probing in the mud; nostrils slit-like, surrounded by soft skin. Schizognathous; precocial. The Limicolæ are all birds of small size, abundant on sandy shores and in marshes. In spite of the difference in appearance and habits, these birds have much in common with the gulls, in their anatomy. (Lat., limus, mud; colo, I inhabit.) Families of Limicolæ. a.

Between the Parrots and the Singing Birds comes the series or so-called order of Picaria, a highly diversified group including all the non-passerine land birds, except the pheasants, doves and birds with cered and hooked bill. In all, the hind toe is small (if present), and sometimes elevated; its claw is usually shorter than that of middle toe. The wing coverts are larger and in more numerous series than in the Passeres. The primarics are 1û in number, the first rarely short; tail usually of 10 feathers. Sternum non-passerine; musical apparatus imperfect; tarsus never presenting an undivided ridge behind. Nature altricial. Recent writers usually subdivide the Picaria into three groups, which are recognized as distinct orders by the American Ornithologists' Union, under the names of Coccyges, Pici and Macrochires. The last two are natural groups and well defined by anatomical characters. The Coccyges, however, are scarcely less varied than the Picaria, of which they form the greater part. Dr. Coues says: "I have no faith whatever in the integrity of any such grouping as Picaria implies, but if I should break up this conventional assemblage, I should not know what to do with the fragments." The so-called order Acanthopteri among fishes is a case somewhat parallel. CUCULIDE. CLVII. 265 ORDER XLIII. COCCYGES. (THE CUCKOO-LIKE BIRDS.) This order includes the majority of the Picarian birds, some 15 families, not having very much in common, except that they lack the special peculiarities of the Pici and the Macrochires. "The sternum is usually notched behind; the syringeal muscles are two pairs at most.” Feet generally short, the toes variously arranged. Palate desmognathous. The group is "a mixed lot requiring to be reconstructed by exclusion of some of the families entering into its composition." (Coues). (kókkuέ, cuckoo.) Families of Coccyges. a. Toes 2 in front, 2 behind; bill as long as head, compressed, the tomia en- tire; nostrils exposed; no rictal bristles; toes cleft to base. CUCULIDE, 157. aa.

(Lat., picus, woodpecker.) a. Nostrils covered by feathers; tail feathers rigid and acute. PICIDE, 159. FAMILY CLIX. PICIDE. (THE WOODPECKERS.) Bill stout, usually straight, with the tip truncate or acute, fitted for hammering or boring into wood. Tongue long, flattish, barbed, capable of great protrusion, adapted for securing insects (except in Sphyrapicus); hyoid apparatus peculiar, its horns generally quite long, curving around the skull behind and over forward again to the ear or beyond. Feet zygodactyle, the hind toe sometimes want- ing; claws compressed, sharp and strong. Tail feathers 12, rigid and acuminate, the outer pair short, concealed; tail never forked ; nasal tufts present. Chiefly arboreal; all (except Sphyrapicus, which is truly a “Sap- Sucker,") are pre-eminently insectivorous. For this reason these birds are of the greatest service to the farmer.

I prefer to use Hylatomus, Eremophila, Lagochila, Lucania, Icteria, Cestreus, Heterodontus, and similar names, notwithstanding their similarity to Hylotoma, Eremophilus, Lagocheilus, Lucanus, Icterus, Cestræus, and Heterodon.

Wings very long, thin and pointed; secondaries very short. Feet small, weak; hind toe often elevated or otherwise turned; toes com- pletely cleft; middle claw not pectinate; no rictal bristles; tail feathers 10; plumage compact. In most species the salivary glands are highly developed, and their secretion is used as a glue in the construction of the nest; species of Collocalia in China thus form the edible bird's nest. Small birds of the warmer parts of the world, bearing a superficial resemblance to Swallows, but struc- turally very different, being closely related to the Humming Birds, nearer to them even than to the Goatsuckers.

Toes always 4; feet fitted for perching; the hind toe always on the level of the rest, its claw at least as long as that of the mid- dle toe; joints of toes 2, 3, 4, 5, respectively, from first to fourth; none of the toes versatile, and none webbed; wing coverts few, chiefly in two series; tail feathers 12; primaries 10, but in most of the families the first one is reduced in size, and often rudimen- tary and displaced; musical apparatus more or less developed ; sternum of a uniform passerine pattern; palate ægithognathous. Nature altricial. This order includes about 6000 known species, or more than half of all the kinds of birds. They represent the "highest grade of development and the most complex organization of the class; their high physical irritability is co-ordinate with the rapidity of their respiration and circulation; they consume the most oxygen and live the fastest of all birds." (Coues.) A considerable number of anatomical characters (for which see Stejneger, "Standard Natural History,” p. 458, et seq.), are more or less perfectly distinctive of the Passeres. These cannot, how- ever, be discussed here. The group is divided, on anatomical charac- ters, into about 5 suborders. Two of these groups, the Clamatores and the Oscines, are represented in our fauna. The latter, charac- terized especially by the perfect musical apparatus, comprises the vast majority of the Passeres. (Lat., passer, sparrow.) Families of Passeres. a. Tarsus with its hinder edge rounded; encircled by a single horny envelope divided into scutella anteriorly and on outer side, this sometimes ex- tending all round (though separated by a seam along inner side), but often widely separated on inner side or behind or both, the intervening space occupied by granular scales, reticulations, or plain naked skin; musical apparatus imperfect; primaries 10, the first about as long as second. (Clamatores.) b. Inner toe free at base from middle toe; tarsus not reticulate behind; bill hooked at tip, with long rictal bristles. TYRANNIDÆ, 163. aa. Tarsus with its hinder edge compressed, forming a sharp, nearly undi- vided ridge (except in the Larks, which may be known by the long, nearly straight hind claw); musical apparatus highly developed; pri- maries properly ten, but the first short, or spurious, or sometimes rudi- mentary and misplaced, so that but nine are evident, in which case the first developed primary is about as long as second. (Oscines.) 272 XLVI. AVES: PASSERES. * c. Hinder edge of tarsus not compressed, rounded and scutellate like anterior edge; hind claw very long, straightish; developed pri- maries 9. ALAUDIDA, 164. cc. Hinder edge of tarsus compressed, forming a sharp ridge, for the most part undivided. d. Primaries apparently but 9 (the first minute and displaced); the first developed (i. e. second) primary about as long as the next; bill not hooked at tip. e. Bill not fissirostral, the gape little longer than the culmen; outer primary never twice as long as inner. f. Bill "conirostral," stout at base, with the commissure forming a more or less distinct angle at base of bill, "the corners of the mouth" drawn downward. g. Bill rather long, often longer than head, without notch at tip or bristles at the rictus. ICTERIDE, 166. gg. Bill shorter than head, often notched near tip, and usually with bristles at the rictus. FRINGILLIDE, 167. • • ff. Bill not truly conirostral (the corners of mouth not evidently drawn downward). h. Bill stout (conical in our species, the cutting edge with one or more lobes or nicks near its middle); nostrils placed high, exposed; (plumage chiefly red or yellow, in our species). TANAGRIDE, 168. hh. Bill rather slender, not conical; angle of gonys not be- fore nostril. i. Hind claw short and curved, mostly shorter than its toe; tertials not elongate, not nearly reaching tips of pri- maries. MNIOTILTIDE, 173. ii. Hind claw long and straightish, mostly longer than its toe; tertials much elongate, nearly reaching tips of primaries. MOTA CILLIDA, 174. ee. Bill fissirostral, the culmen very short, the gape very broad, its length more than twice the culmen; wings very acute, the outer primary more than twice length of innermost. HIRUNDINIDE, 169. dd. Primaries evidently ten, the first developed, but short, rarely half the length of the next; (first primary obsolete in some Vireos, known by the slightly hooked bill). j. Tarsus distinctly scutellate. k. Tarsus not longer than middle toe with claw; bill short, depressed; (head crested; tail tipped with yel- AMPELIDÆ, 170. low, in our species). kk. Tarsus longer than middle toe and claw (or if not, other characters not as above). 1. Bill strongly hooked and toothed at tip, somewhat like a hawk's bill. LANIIDE, 171. 1.

Primaries 10; the first more than & length of second, longer than in any other of our passerine birds; bill typically broad, triangular, depressed, abruptly hooked and notched at tip, with long rictal bristles; commissure nearly straight; nostrils small, usually partly concealed. Tarsus with its back and sides as well as the front covered with scutella, so that there is no undivided ridge behind, as in most other Passeres. Feet small. Mouth capacious; vocal apparatus mesomyodian, i. e. the "syrinx with fewer than 4 dis- tinct pairs of intrinsic muscles inserted at the middle of the upper bronchial half rings, constituting an uncomplicated and ineffective musical apparatus." (Coues.) Changes of plumage slight; ours mostly olivaceous. A large family of 80 genera, and more than 300 species; all American and mostly tropical. All are insectivorous, most of them pre-eminently so; they are, therefore, in our latitude, migratory. a. Bill of typical form, depressed, hooked at tip, with strong rictal bristles. b.

FRINGILLIDA.¹ (THE FINCHES.) Primaries 9, the first being obsolete. Bill "conirostral," mostly shorter than head, robust, of a conical form, with the commissure more or less abruptly angulated near its base; in other words, the corners of the mouth drawn down." This feature is usually strongly marked, and it is almost the only special character per- taining to all the members of the family. Even this is also shared by the Icterida, which, however, may generally be distinguished by the greater length and slenderness of the bill. Nostrils high up, exposed or (in northern species) partly covered by a ruff of small ■ Sundevall and Stejneger have placed the Fringillidæ at the end or head of the series of birds, for reasons which seem to me sufficient ones. "In order to find out the most specialized form of the Passeres, we must look for the bird which is most specialized in all directions, not only as to the coloration of its plumage, or the fusion of its tarsal covering. The ideally highest form . . . would have booted tarsi, 9 primaries, long nandibular symphysis, powerful bill for grain crushing, a digestive system adapted for grain-feeding, and the coloration of young and adult unspotted and similar. That this is the regular course and ultimate end of the evo- lution among the higher birds is evident from the fact that we can trace it in nearly all the groups, and in the individual development of the birds possessing these characters." (Stejneger.) Acting on this principle, Stejneger selects as the highest or most specialized bird the Evening Grosbeak. "The number of its primaries is reduced to 9, the inandibu- lar symphysis is well developed, the palatine and facial part of the skull is highly specialized, and so is the digestive canal. Furthermore the plumage of the young is essentially like that of the adults." It fails, then, in only one respect, -its tarsus is not booted. In most recent American systems, however, the Turdidae are placed at the head of the list; and as the A. O. U. has adopted this arrangement it is retained here, the "post of honor" being given to the beautiful Arctic Bluebird rather than to the Evening Grosbeak, although the latter has certainly the better claim. FRINGILLIDÆ. 281 CLXVII. feathers. Tarsus scutellate in front, with an undivided ridge behind. A very large family, the most extensive in Ornithology, com- prising about 100 genera and 500 species, found in nearly every part of the world, except Australia. They are especially abundan in North America, where about one seventh of all the birds are Fringillida. "Any one United States locality of average attract- iveness to birds, has a bird-fauna of over two hundred species, and if it be away from the sea-coast, and consequently uninhabited by marine birds, about one-fourth of the species are Mniotiltide and Fringillida together, the latter somewhat in excess of the former. It is not easy, therefore, to give undue prominence to these two families." (Coues.) All the Finches are granivorous, feeding chiefly on seeds, but not rejecting either berries or insects; nearly all sing, and some most delightfully; most of them are plainly clad, a streaky brown being the prevailing tint, but others are among the most brilliantly col- ored birds. Among these latter only are the changes in plumage strongly marked. (Lat., fringilla, finch.) A strictly natural analysis of the genera of Fringillide is prac- tically impossible, as they do not fall naturally into definable groups. The characters drawn from the development of the palate are not available for the ordinary purposes of the student. The following semi-artificial key is largely adapted from Ridgway's Manual. a.

A rather small family, comprising 5 genera and 60 to 70 species of small olivaceous birds, all American. They are allied to the VIREONIDE. 295 CLXXII. Laniidæ, being in fact small insectivorous Shrikes. The color- ation is usually blended, and varies little with age or sex. Many of them are remarkable as songsters. Concerning the "nine-primaried" species, Professor Baird re- marks: “In V. flavifrons, in which the outer primary is supposed to be wanting, its presence may be easily appreciated. One of the peculiar characters of this species consists in a narrow edging of white to all the primary quills, while the primary coverts (the small feathers covering their bases, as dis- tinguished from what are usually termed the wing coverts, which more properly belong to the forearm or secondaries) are without them. If these coverts are carefully pushed aside, two small feathers considerably shorter than the others will be disclosed, one overlying the other, which (the under one) springs from the base of the exposed portion of the long out- ermost primary, and lies immediately against its outer edge. This small feather is stiff, falcate, and edged with white like the other quills, and can be brought partly around on the inner edge of the large primary, when it will look like any spurious quill. The overlying feather is soft, and without light edge. In the other Vireos, with appreciable spurious or short outer primary, a similar examination will reveal only one small feather at the outer side of the base of the exterior large primary. In all the families of Passeres, where the existence of nine primaries is supposed to be characteristic, I have invariably found, as far as my ob- servations have extended, that there were two of the small feathers re- ferred to, while in those of ten primaries but one would be detected." a.

Primaries 9; inner secondaries not enlarged, nor the hind toe long and straight, as in Alaudida and Motacillida. Bill usually rather slender, notched or not; the commissure not angulated at base, as in Fringillidæ, nor toothed in the middle, as in some Tana- gridæ; the end not notched and abruptly hooked, as in Vireonidæ and Laniidæ; the gape not broad and reaching to the eyes, as in Hirundinidæ. The Warblers are small birds; all, except Icteria, are less than 6½ inches in length, and very many are less than 5. The colors are usually brilliant and variegated, but the sexes are unlike, and the variations due to age and season are great, so that the identification of immature birds is often very difficult. Many of MNIOTILTIDÆ. 297 CLXXIII. the Warblers are pleasing songsters, but none exhibit any remark- able powers in that line. The name " Warbler " comes from their resemblance to the warblers of Europe (Sylviidæ) and not from any distinguished musical quality of their own. All are insectivo- rous and migratory. This family consists of more than 100 species, all American. The Mniotiltidæ grade perfectly into the Carebida and Tanagridæ, and the last as perfectly into the Fringillida. Convenience is the only excuse for retaining any of these groups as distinct families. a. Bill not depressed and fly-catcher-like; rictal bristles if present scarcely reaching beyond nostrils. b.

Primaries 10, the first short, hardly spurious; wings moderate or long. Bill usually more or less slender, with or without a notch near the tip; nostrils not covered by bristles. Tarsus scutellate, the plates usually distinct. The Miminæ, now associated with the wrens by the A. O. U., are in many respects intermediate between wrens and thrushes. Their reference to either group is chiefly a matter of convenience. The wrens are sprightly, fearless and impudent little creatures, apt to show bad temper when they fancy themselves aggrieved by cats or people, or anything else that is big or unpleasant to them; they quarrel a good deal, and are particularly spiteful towards martins and swallows, whose homes they often invade and occupy. Their song is bright and hearty, and they are fond of their own music; when disturbed at it they make a great ado with noisy TROGLODYTIDÆ. 307 CLXXV. scolding. Part of them (Cistothorus) live in reedy swamps and marshes, where they hang astonishingly big globular nests, with a little hole on one side, on tufts of rushes, and lay six or eight dark- colored eggs; the others nest anywhere."

Rocky Mountains, E. to Missouri R.; the prettiest of thrushes and one of the most attractive of our birds. With this beautiful bird we close the long series of feathered Sauropsida. The next class, the Mammalia, is widely different from the birds, but its lowest forms, the Monotremes, approach the common rep- tilian stock from which both mammals and birds have probably sprung. 314 MAMMALIA. CLASS I. MAMMALIA. (THE MAMMALS.) A Mammal is a warm-blooded, air-breathing vertebrate, having the skin more or less hairy (or rarely naked); viviparous, the em- bryo developed from a minute egg destitute of food-yolk (except in the Monotremata, in which group the eggs are large, as in Rep- tiles, and are developed outside the body); the young nourished for a time after birth by milk, secreted in the mammary glands of the mother; respiration never by means of gills, but after birth by lungs, suspended freely in the thoracic cavity, which is completely separated from the abdominal cavity by a muscular septum (the diaphragm); heart with four cavities; a complete double circula- tion; blood warm. Skeleton more firm than in other Vertebrates, the bones containing a larger proportion of salts of lime. Skull articulating with the atlas by means of two occipital condyles; bones of face immovably joined by sutures; each half of lower jaw of a single bone, articulating directly with the skull, the quadrate bone becoming one of the bones of the ear (the malleus). Brain case comparatively large, corresponding with the increased devel- opment of the brain. The numerous other peculiarities of the skeleton and the viscera need not be noticed in this connection. The following analysis of the Orders of Mammals which occur within our limits is mostly taken from Professor Gill's "Arrange- ment of the Families of Mammals." Orders of Mammalia. a. Young developed within the uterus from a minute egg which is destitute of food-yolk; milk glands with nipples; no cloaca. (EUTHERIA.) b. Young born when of very small size and incomplete development, never connected by a placenta to the mother; brain small, its corpus callosum rudimentary. (Subclass DIDELPHIA.) MARSUPIALIA, XLVII. bb. Young not born until of considerable size and nearly perfect develop- ment, deriving its nourishment, before birth, from the mother through the intervention of a placenta; a well developed corpus callosum. (Subclass MONODELPHIA.) • c. Brain with a relatively small cerebrum, which does not cover the other ganglia, much of the cerebellum being exposed behind, and in front much of the optic lobes. (Ineducabilia.) d. Canine teeth none; incisors 3, rarely, chisel-shaped; limbs adapted for walking. GLIRES, XLVIII. • dd. Canine teeth present, in some form; incisors not nor . MAMMALIA. 315 e. Anterior limbs not adapted for flight; ulna and radius not united; hand normal; mammæ usually abdominal. INSECTIVORA, XLIX. ee. Anterior limbs adapted for flight; ulna and radius united; bones of hand and fingers much elongated, supporting a thin, leathery skin, extending along sides of body to the posterior limbs; mammæ pectoral. CHIROPTERA, L. cc. Brain with a relatively large cerebrum overlapping much, or all, of the cerebellum and optic lobes. (Educabilia.) f. Posterior limbs absent, the pelvis rudimentary; anterior limbs reduced to broad flattened paddles, without distinct fingers or claws; no clavicles; tail with a broad, horizontally placed caudal fin; cervical vertebræ more or less grown together; carnivorous. CETE, LI. ff. Posterior limbs and pelvis well developed; anterior limbs with hoofs, claws, or nails. • g. Femur and humerus not exserted beyond the common integu- ments of the body; clavicles more or less rudimentary; mammæ abdominal or inguinal. ous. • • h. Feet with hoofs; molars mostly with grinding surfaces; in- cisors various; no tusks; developed toes, 1 to 4; herbivor- UNGULATA, LII. hh. Feet with developed claws; canines specialized; molars, one or more, sectorial, adapted for cutting; incisors &; carnivorous. FERE, LIII. gg. Femur and humerus exserted; feet with distinct toes which are provided with nails; clavicles present; an inner digit of hand (thumb) opposable to the others; orbits encircled by bone and directed forwards; mammæ pectoral, two in number (rarely also an inguinal pair). PRIMATES, LIV. ORDER XLVII. MARSUPIALIA. (THE MARSUPIALS.) Young developed without a placenta, and born at a very early stage and incomplete condition of development. The young at birth are usually placed in an abdominal pouch formed by a fold of skin about the milk glands of the mother, where they remain for a considerable time. Reproductive organs in both sexes of peculiar structure, nearly all the parts being double in the female. Skele- ton showing numerous peculiarities, the teeth usually more numer- ous than in the higher Mammals. Brain small, the corpus callosum rudimentary. Heart with two vena cava. This large group is chiefly confined to Australia. It represents an early or primitive type of Mammalia, which has now become extinct in most parts of the world. The single non-Australian family approaches most nearly to ordinary Mammals. (Lat., marsupium, pouch.) Families of Marsupialia. a. Tail long, prehensile, nearly naked; feet plantigrade, 5-toed, the first toe thumb-like and without claw; teeth 50. DIDELPHIDIDE, 180. 316 MAMMALIA: GLIRES. - XLVIII. FAMILY CLXXX. DIDELPHIDIDÆ. (THE OPOSSUMS.) Marsupial mammals of small size, with the teeth i. §:½, c. 1:1, pm. §:8, m. 4:4. Feet five-toed, plantigrade, the claws 5-4. Tail usually very long, prehensile, nearly naked, covered by a scaly skin, with a few scattered hairs. Genera 2, species about 15; all Ameri- can and chiefly belonging to the tropics. The common opossum is one of the largest of the group. All are sluggish animals, arboreal (Didelphis) or aquatic (Chironectes), and becoming very fat. They feed on insects and other small animals. a. Arboreal; feet not webbed. DIDELPHIS, 536. 536. DIDELPHIS Linnæus. (dís, two; deλþús, womb.) 1029. D. virginiana Shaw. COMMON OPOSSUM. Soiled yel lowish, with some darker hairs; ears black, leathery; legs dark. L. 35. T. 15. N. Y. to Cal. and S.; common. ORDER XLVIII. GLIRES. (THE RODENTS or Gnawers.) Mammals with the incisor teeth or in number, chisel-shaped, adapted for gnawing; no canine teeth, a toothless space in the place of canines; molar teeth adapted for grinding; cerebrum small, little convoluted; intestinal canal elongate; ears and eyes usually well developed. Food chiefly vegetable. The Glires or Rodentia is the largest order of Mammals, and in individuals by far more numerous than any other. Most of the species are of small size, the Beaver being one of the very largest of the forms now living. "Though a feeble folk, comparatively insignificant in size and strength, they hold their own in legions against a host of natural enemies, rapacious beasts and birds, by their fecundity, their wari- ness and cunning, their timidity and agility, their secretiveness, each after the means by which it is provided for exercising its in- stinct of self-preservation, among which insignificance itself is no small factor."

(Lat., flying.) “But we have reached the end of the chain of rodent beings of the earth, the water, and almost of the air, a cycle of mammalian life which circumscribes extraordinary diversity of form and func- tion, revolving about a single central point of organization, namely, adze-like teeth, to gnaw wood with. The number of individuals which make a living in this way in a world of Malthusian strife is simply incalculable. Yet they have one obvious part to play, that of turning grass into flesh, in order that carnivorous Goths and Vandals may subsist also, and in their turn proclaim, ‘All flesh is grass.'"

Most of them are insectivorous, a few in tropical regions feeding on fruits. About 400 species are known, chiefly of small size. The order is very sharply defined, but it has probably sprung from the same stock as the Insectivora. (xeip, hand; πrepóv, fin.) a.

(μακρός, large; ous, ear.) ORDER LI. CETE. (THE CETACEANS.) Mammals of the sea, more or less fish-like in form, and adapted for life in the open ocean. Bones of the neck short, more or less fused; posterior limbs wanting; pelvis rudimentary; anterior limbs developed as broad, flattened paddles, without distinct fingers and without nails. Nostrils developed as spiracles, and opening usually on top of head, thus enabling the animals to breathe with- out raising the head from the water; eyes small; no external ear; skin nearly or quite destitute of hair; tail ending in a broad hori- zontal fin or paddle; back sometimes with a dorsal fin. Skin thick and tough; beneath it a thick layer of fat (blubber), which pro- tects the animal from the cold. Species numerous; found in all seas, some of them being the largest of all animals. The nearest relationships of the whales are perhaps with the seals, among living forms, but the differentiation is now very wide. Of the numerous species occasionally straying to our coasts, the following seem prop- erly to belong to our fauna. The nomenclature and analysis of genera is chiefly taken from True's paper on "Collecting specimens of Cetaceans," in Rept. U. S. F. C. for 1883-1885. I have also made considerable use of MSS. lists of species, kindly given me by Mr. F. W. True, and by Professor Cope. (KĥTOS, whale.) Families of Cete. a.

'According to Professor Cope, this genus is a doubtful one, S. tectirostris being perhaps not really different from Balanoptera (Physalus) physalus. Probably Physalus and Sibbaldius should be united to Balanoptera. (True.) CERVIDÆ. CXCV. 335 ORDER LII. UNGULATA. (THE HOOfed Mammals.) Herbivorous mammals provided with 1 to 4 enlarged and thick- ened claws or hoofs on each foot; molar teeth adapted for grind- ing. The anatomical characters of this well-known and varied group are too numerous to be here summarized. The order is usually subdivided into the Perissodactyli, or odd-toed ungulates, and the Artiodactyli or even-toes. The former group is exempli- fied by the Horse (Equus caballus L.), the Ass (Asinus asinus L.), the Rhinoceros and the Tapir. The Artiodactyli are again sub- divided into the non-ruminating, omnivorous, hornless, naked or bristly allies of the Common Hog and Wild Boar (Sus scrofa), and the group of Pecora (Ruminants). To the latter belong all the living ungulates occurring within our limits. (Lat., ungulatus, hoofed.) Families of Ungulata. a. Feet bifid; first toe wanting; second and fourth rudimentary. (Artio- dactyli.) b. Stomach compound, of 3 or 4 compartments; horns usually present. (Pecora.) c. Upper jaw without incisors, in the adult. d. Horns solid, usually branching, deciduous. CERVIDA, 195. dd. Horns permanent, hollow, each enclosing a process of the frontal bone. BOVIDE, 196. FAMILY CXCV. CERVIDÆ. (THE DEER.) Horns deciduous, solid, developed from the frontal bone, more or less branched, covered at first by a soft, hairy integument, known as "velvet "; when the horns attain their full size, which they do in a very short time, there arises at the base of each a ring of tubercles known as the "burr;" this compresses and finally ob- literates the blood-vessels supplying the velvet, which dries up and is stripped off, leaving the bone hard and insensible; the horns or "antlers are shed annually, the separation of the "beam" from its "pedicel" taking place just below the burr; antlers are wanting in the female (excepting in the Reindeer) but they are present in the male of nearly all species. Stomach in four divisions, of the ordi- nary ruminant pattern. Dental formula, i. § §; c. (usually) { fi pm. §§; m. :. A widely distributed family of about 13 genera. a.

ORDER LIV. PRIMATES. (THE ANTHROPOID MAMMALS.) Both limbs nearly or quite outside of the common integument of the body; fingers and toes usually 5, the thumb sometimes wanting, when present opposable to the others; great toe with a depressed nail; teeth various, usually with distinct incisors, canines and mo- lars; clavicles completely developed; shoulders distinct, well-sep- arated; brain large, the cerebrum and cerebellum highly developed; parts of the brain well differentiated. Mammæ pectoral, except in some lemurs. A large and varied order, the highest among animals, comprising men, apes, baboons, monkeys, and lemurs. The lemurs diverge in many respects from the other primates, and should per- haps stand as a separate order (Prosimii). The structural pecu- liarities of man are not numerous, and are mostly correlated with the great development of the brain, the chief peculiarity character- istic of the Hominidæ. (Lat., primatus, the chief place.) Families of Primates. a. Hair on body little developed, except in certain specialized areas; body erect in locomotion; great toe not opposable; dentition i. ; c. 1; pm. 3; m. § on each side; no gaps between the teeth. HOMINIDÆ, 203. 344 LIV. MAMMALIA: PRIMATES. FAMILY CCIII. HOMINIDÆ. (THE MEN.) The most prominent characters of the Hominidæ are "derived from the distribution of hair on the body, which is subject to wide modification in the different races, from the fact that locomotion is easiest in the erect posture, owing to the relative shortness of the arms; from the greater length and mobility of the thumb and the comparative immobility of the great toe. Well-marked skeletal peculiarities are the possession of 12 rib-bearing vertebræ, the rounded skull in which the muscular ridges are little prominent, and the great capacity of the cranium. This is, of course, in adaptation to the relatively enormous development of the cerebral hemispheres, which much exceed in bulk those of other primates and to which man owes his specific name." It is apparent that dif- ferent races have arrived at different stages of evolution in the development of the brain, "as well as in the employment of articu- late speech, to which man owes the power of transmitting to others the results of his experience and his position as the 'highest ani- mal.' (R. Ramsay Wright.) As usually understood, this family contains but a single species, cosmopolitan, and highly variable. 607. HOMO Linnæus. (Lat., man.) i 1145. H. sapiens L. MAN. This species is now split up into many sub-species or races, the native man of this continent, or "American Indian," being var. americanus L. Other races now naturalized in America are the Caucasian race, var. europæus L., the Mongolian race, var. asiaticus L., and the Negro race, var. afer L. The first of these is an immigrant from Europe, the second from Asia, and the third was brought hither from Africa by repre- sentatives of var. europæus to be used as slaves. The wild man, or typical var. sapiens, as described by Linnæus ("Homo diurnus : varians cultura, loco. tetrapus, mutus, hirsutus "), seems to be now extinct. (Lat., knowing.)

Dorsal fin. Second dorsal fin. L. D. 2d D. = P. V. Ventral fins. A. Anal fin. C. Pectoral fins. Caudal fin. B.Branchiostegals. Vert. FO Vertebræ. The number is usually divided into abdominal and caudal vertebræ; the latter having the hæmapophyses united, forming hæmal spines. Thus Vert. 10+14, the usual number in typical fishes, means 10 abdominal and 14 caudal vertebræ. Male. ?=Female. Roman numerals used with abbreviations for the fins indicate the number of spines or inarticulate rays in a fin. Arabic numerals indicate the number of soft rays. In a fin containing both spines and soft rays, a comma (,) separating the numerals indicates that the two kinds of rays are continuous, or more or less connected. A dash (—) indicates GLOSSARY OF TECHNICAL TERMS. 357 their separation. Thus, “D. X, 12," describes a single dorsal fin with 10 spines and 12 soft rays; "D. X — 12," indicates two dorsal fins the first of 10 spines, the second of 12 soft rays; "D. X—I, 12,” would indicate the presence of a single spine in the second dorsal. The posterior soft ray of the dorsal and anal fins is usually split to the base. It should be counted as one ray and not as two. “Gill rakers 5+15," indicates 5 above and 15 below angle of gill- arch; rudiments not counted. When the number above the angle is uncertain or non-essential, it is indicated as "x." Lat. l. Lateral line, i. e., the number of scales contained in its course. When the lateral line is obsolete, "lat. 1." signifies the number of scales in a row from the head to the base of the caudal fin. Thus, "lat. 1. 36" means that there are 36 scales in a row along the sides from the head to the caudal. "Scales 5-36-10" indicates the presence of 36 scales in the lateral line itself; 5 scales in a vertical series between front of dorsal and lateral line, and 10 scales between lateral line and vent. In all cases the number of rays or scales, as given in the descrip- tions, is intended to represent a fair average, and a variation of one- sixth, or even more, in either direction need not surprise the student. Generally the spines and scales are more constant in their numbers than the soft rays, and the fewer of either, the less variable. Length, as used in proportionate measurements, is distance along the side from tip of snout to end of last vertebra. It does not include the caudal fin. Depth in length. The greatest depth of the body as contained in the distance along the side from the snout to the base of the caudal. Head in length. = The distance from the snout along the cheeks to the extremity of the opercle, as contained in the distance from the snout to the base of the caudal. Eye in head. Its longitudinal diameter as contained in the length of the side of the head. As above stated, these measurements, as given in the descriptions, are intended to be the average of living adults, and must be applied to young specimens or preserved ones with caution. Young fishes are usually but not always more elongate than adults, and the eye is proportionally much larger. A fin is said to be "long" when it has a long base, or is many-rayed. A "high" fin is one in which the individual rays are elongated. II. REPTILES. L.Length in inches of an adult example, from tip of snout to tip of tail. Sc. or Scales. Number of longitudinal rows of scales exclusive of the ventral series. 358 GLOSSARY OF TECHNICAL TERMS. V. P. Number of ventral plates, or gastrosteges, counted along the belly, from the throat to the vent. The figures given in the descriptions are intended to be average, the actual number being somewhat variable. S. C. P.― Number of pairs of sub-caudal plates, or urosteges, counted from the vent to the tip of the tail. III. BIRDS. L.=Length in inches (along back from tip of bill to end of longest tail feather); thus, "L. 7" means, length 7 inches. E. Extent (spread of wing) measured in inches. W.=Length of wing (from bend of closed wing-carpal joint-to tip of longest feather) in inches. T.=Length of tail in inches (i. e., actual length of the longest tail feather). B.=Length of bill in inches (measured along middle line of culmen to tip of bill). Hd. Length of head in inches (measured with dividers from base of bill to nape.) Ts. Tcl. = Length of Tarsus in inches (measured in front). Length of middle toe with its claw. The measurements given in the descriptions are understood to repre- sent a fair average adult male; a variation of one-sixth, or more, in absolute length is nothing unusual; relative lengths, as of wings and tail, are much more constant. To save space I have usually preferred to say "L. 6," to saying "L. 5 to 61.” 오 ​= Male. = Female. Yg. Young. >=More than, longer than, or more than equivalent to. <=Less than, in its various senses. Sign of equivalence. The toes are numbered 1, 2, 3, 4; 1 being the hind toe, or hallux; 2 the inner anterior toe; 3 the middle toe; and 4 the outer toe. IV. MAMMALS. L. Length in inches from tip of snout to tip of last vertebra of tail. T.=Length of tail in inches (exclusive of hairs). i. Incisor teeth. C. - Canines. рт. Premolars. m.=Molars. GLOSSARY OF TECHNICAL TERMS. 359 Thus, "i. " indicates two incisor teeth on each side in the upper jaw, and one on each side in the lower. "Toes 5-4" implies fore feet five-toed, hind feet four-toed. NOTE. As authority for names of species in this work, the original describer of the species is alone given. The name is written in full except in case of Linnæus, abbreviated as "L." In case the original combination of general and specific name is still retained, the name of the author is printed without parentheses. In case, however, the original describer placed the species in question in a genus different from the one here adopted, the author's name is enclosed in parentheses. Thus (page 277), “ Corvus corax L." means that Linnæus placed his species corax in Corvus, where it still remains. “Melanerpes erythrocephalus (L.)," indicates that the species (Picus erythrocephalus of Linnæus) is now placed in a genus different from the one in which it originally stood. Melanerpes is a modern subdi- vision of Picus, which formerly included all Woodpeckers. Eu." indicates that the species in question is also found in Europe. CORRECTIONS IN SIXTH EDITION.
