In the body of this work I have endeavored to include all the species known to inhabit the State, and to exclude all that are not known to occur within our limits. Since, however, there are several species which are, judging from their geographical distribu- tion, likely hereafter to be taken within the State, I have added their names in an appendix. Of all the species mentioned in this paper I have given as accurate descriptions as I have been able to prepare; and I have endeayored to state also the most important facts known regarding their habits. It is to be hoped that this endeavor will incite others to study our lower vertebrates with respect to their manner of life, since too little is known about even the commonest species. I am indebted to many friends for aid in preparing this work, so many that I can not here mention all their names. Under each species I have tried to give due credit for specimens and notes. I must here, however, - acknowledge the liberality of Dr. Leonhard Stejneger, Curator of Rep- tiles in the National Museum, Washington, D. C., in giving me free ‘access to the large collections there; also the kindness of Prof. B. W. Evyermann, who allowed me to examine a considerable collection made by himself, mostly in the vicinity of Terre Haute. This collection is the property of the State Normal School. To Prof. S. S. Gorby I owe the op- portunity to examine the specimens in the State Museum. Some years ago I had occasion to study a collection made at New Harmony by the late Mr. James Sampson, of that place. For the opportunity of doing this I am indebted to Prof. John Collett. The writings of Agassiz, Cope and other naturalists have been consulted in the earnest desire to obtain a correct idea of our batrachian and reptilian fauna.

THe AUTHOR. TIrvincron, Inp., Sept. 1, 1892. THE BATRACHIANS AND THE REPTILES OF INDIANA. On the part of people who have not made a scientific study of animals no distinction is made between the group of creatures here called Batra- chians and that group called Reptiles. The amphiuma and the snakes, the salamanders and the lizards, the common toad and the turtles are all called ‘‘reptiles.’’ Nor is this strange when we consider how closely members of both groups resemble one another in outward form and in habits. If is indeed only recently that zodlogists, who endeavor to found their systems on more important differences than appear on the outside, have agreed to regard the frogs, salamanders, and newts, as fundament- ally different from the lizards, turtles, and snakes. In reality, the ba- trachians are more closely related to the fishes than to the reptiles, while the latter are more nearly akin to the birds. The batrachians form a class standing intermediate between the class of fishes and the class of reptiles. . Nevertheless, since zodlogists have almost universally associated the two classes in their works, and since people do not usually distinguish the one kind of animals from the other, they are here described together. The batrachians differ from the reptiles in several important respects. The skin of the former is usually smooth and moist, sometimes raised up into warts, as in the toads, but never disposed in overlapping scales or regular plates. Scales and plates, such as are seen in the lizards and snakes, and tortoises, are almost universal among the reptiles No In- diana reptile is without such a covering, except our soft-shelled turtles. The life-history of the members of the two groups is also widely different. The batrachians almost always lay their eggs in the water, and the young pass their early days there as tadpoles. They respire by means of gills until the time of their metamorphosis approaches, when lungs are de- veloped, the gills are absorbed, and the animal leaves the water and lives to a greater or less extent on the land. Reptiles, on the contrary, lay their eggs on Jand, the young are hatched with the form of the adults, and they never have gills. A few batrachians retain their gills life-long, breathing both by means of these and their lungs. Other dif- ferences exist, but since their determination would require dissections, they are not thought suitable for consideration in a work of this kind. ete * ‘ ee Oe tt Pye ee is ey. 236 5 Since the animals herein described are a source of discomfort and alarm to many people, it may be well to say here that of all the ba- trachians and reptiles known to inhabit Indiana, but four, the yellow- banded rattlesnake, the prairie rattlesnake, the coral snake, and the copperhead, are poisonous. It is possible that the poisonous southern moccasin, or cottonmouth, may yet be found in the southwestern part of the State: if so, we shall have five poisonous species, and five only. . Kry TO THE CLASSES. A. Skin usually smooth and soft, sometimes rough and warty, never forming scales that overlap or are arranged in regular rows; eggs usually laid in the water and giving origin to tadpoles. (Water-dogs, salamanders, frogs and toads. ) Batrachia, p. 5. AA. Skin usually having epidermal scales or large regular plates; these usually arranged in a regular manner, often overlap- ping. Eggs laid on land. Young with form of adults. (Snakes, lizards, turtles, alligators, etc.) Reptilia, p. 79. BATRACHIA. The Batrachia include a great variety of animals that are found living in all except the coldest parts of the earth and the salt water. As al- ready stated, they are, with rare exceptions, hatched in the water, where they spend at least a portion of their lives. A few forms retain their gills throughout life, and seldom or never leave the water. Ina few cases the eggs are laid on the land, under sticks and stones; the young from such eggs may have very rudimentary gills and consequently never enter the water. Such species closely approach, in their habits, the reptiles. The gills may be either internal or external; usually they are of the latter kind. The external gills are attached to processes of the skin, and not to the branchial arches. The internal gills of the tad- poles or frogs grow out from the branchial arches, as in fishes. The skin of the batrachians is richly provided with glands. These secrete a milky fluid, which is often acrid, and sometimes poisonous to the enemies of the species producing it. It thus serves as a means of defense to these animals, which are otherwise almost helpless, Often the glands are collected into groups, as in the ease of those on the back of the head of the common toad. In some species the skin forms a fin on the upper and lower sides of the tail; but in such fins there are no rays, such as are found in the fins of fishes. 6 When limbs are present they have the same skeletal elements as the limbs of reptiles and mammals. Some batrachians are devoid of limbs. All of our species have the anterior limbs present; most of them have also the posterior pair. The anterior limbs never have more than four fingers; the posterior may have five toes. Not much can be said here regarding the skeleton. The vertebre are usually either amphiccelous or opisthoccelous. Ribs are often absent; when present they do not connect with a sternum below. In the lower forms as many as four branchial arches may be present; in the higher species the number is reduced. There may be teeth on the maxillaries, premaxillaries, yomers, and dentaries; more rarely on the palatines, the pterygoids and the splenials. A band of teeth may be found in some cases supported by the parasphenoid. The teeth are almost al- ways very simple in structure, pointed, and grown fast to the support- ing bones. Breathing is effected in the adult by drawing the air into the mouth through the nostrils, then closing these, contracting the cavity of the mouth, and thus forcing the air into the lungs. Hence, a frog may be suffocated by holding its mouth open. For additional information on the anatomy of the Batrachia the student should consult Prof. Huxley’s article, ‘‘Amphibia,”’ in the En- eyclopedia Britanica; also for the Urodela, Dr. R. Wiedersheim’s work, ‘« Kopfskelet der Urodelen.”’ 4 The living species of Batrachia have been divided by Prof. E. D. Cope (51, 13) into four orders, viz: Proteida (Nectwrus), Urodela, Trachy- stomata (Siren), and Salientia. I prefer here to retain the genera Nee- turus, «roteus and Siren under the Urodela. Key TO THE ORDERS OF Batrachia A. Limbs present or absent; when present, the hinder pair not much more strongly developed than the anterior. Tail developed or not; present in all our species. Animals fitted for creeping on or burrowing in the earth or for swimming in the water. Urodela,-p. 6. AA All four limbs present and the hinder pair greatly developed. Tail wholly absent in the adult Aninaal, when on land, usu- ally progressing by leaping. Salientia, p. 48. Order URODELA Batrachia having a lizard-like, eel-like, or serpent-like form. All limbs, as well as the supporting girdles, absent in the extralimital Cecilide. At least the fore limbs and the shoulder girdle present in all our forms; and usually also the hinder limbs. Posterior limbs never conspicuously 7 larger than the anterior. Proximal elements of the tarsus not elongated. Vertebree numerous, at least 14 in front of the sacrum; these either am- phiceelous or opisthoccelous Ribs present, short. Maxilla present in all except Necturus and Siren. Teeth present on maxillaries, vomero-pal- atines, and on the*dentaries, except in Siren. No tympanic cavities or eustachian tubes. Cloaca opening externally by a longitudinal slit. The Urodela include about 133 species, distributed principally north ~ of the equator. North America furnishes 54 species, 18 of which, at least, are found in Indiana. The order as here defined contains 10 families. Of these, two, the Ceecilidse and the Thoriidee, are not natives of North America. Key ro toe N. A. Famiiies oF Urodela. A. Maxillary bone wanting.

Distribution from North Carolina west to Mexico, and up the Missis- sippi Valley to Alton, Ill., and Lafayette, Ind. ~Indiana localities: New Harmouy (Sampson’s coll.); Mt. Carmel, (Nat. Mus. eoll.); Terre Haute (B. W. Evermann); Lafayette (S. Coul- ter); Washington, Daviess County (C. H. Gilbert). Hasirs.—One of the earliest and best accounts that we have of the habits of this curious animal was given by Dr. B.S. Barton, of Phila- delphia, in a letter addressed to John Gottlob Schneider, the author of ‘‘ Historia Amphibiorum.” Schneider and some other authors supposed that the Siren was only the larva of some yet undiscovered salamander. Barton argues against this notion with ability. He states that the favor- ite resorts of the Stren are the rice ponds and the adjacent muddy grounds. It sometimes attains a length of 20, 30, or even 40 inches. Where it abounds it is, according to Barton, called ‘¢ Alligator” and _ ‘*Water-lizard.” He kept one for almost a year, and experimented with it. During this time, it underwent little or no change in either size or condition of its branchie. While in the water, the gills are incessantly in motion. The animal appears to depend only partially on its gills for oxygen, since various observers have noted its coming frequently to the surface for air. Barton says that in warm weather it comes to the surface every five minutes, while in colder weather it comes up about every fifteen minutes. It has the power to remain under water for more than an hour at least. It appears to spend a good portion of its time burrowing in the mud of swamps. Barton thinks that it sometimes travels overland, although its movements on Jand are slow. An earlier observer, Garden, who corresponded with Linnzeus, declares that the Siren may crawl up on the trunks and limbs of fallen trees, likewise that it sings with a querulous voice similar to that of a young duck. This idea gave origin to the name Siren. It possibly emits a shrill, somewhat hissing tone like that of the Amphiuma. Barton appears to think that the Siren can take water into the mouth through the nostrils; an interesting observation in view of the fact that some salamanders do the same as a means of breath- ing. Cope (57, 224) has recorded his observation that in small specimens _ the branchiz are rudimentary and apparently functionless, and that it is -are not “ strong. only in the adult individuals that the gills are fully developed. Linnzeus affirms that the Siren lives on serpents which it catches and holds with its strong teeth. Barton doubts this, but considering the great voracity of the Batrachia in general, and the large size reached by some of the Sirens, it appears quite reasonable. Their teeth, however, ” Barton fed his specimen on angleworms, pieces of 10 meat, etc. It takes its food with ‘‘inconceivable rapidity.” It can en- dure hunger for long periods. The one kept by Barton was exposed for several days in water at a temperature of 33° or 34° F., and for a few hours was ‘‘ locked up, as it were, in the ice.” Holbrook (54, v. 101) says that this animal lives chiefly in the mud, but this they sometimes leave and take to the water, in which they swim with great swiftness. He says too that they are sometimes found on the~ land, but he did not know why they go there. So far as I am aware, nothing is known concerning the breeding habits of this species. It is so rare in our State that few opportunities are likely to be offered to any observer to study such habits. This will have to be done in the South, where it abounds. I have not seen mention made of specimens having been found of less than three inches in length. Speci- mens of this size are very desirable. Family Il. PROTEIDZ.

Young specimens with a lateral dark band from the snout to the tail. Gills bushy, and in life bright red. Prof. Cope (51, 26) mentions specimens from Ontario which were en- tirely black. This species reaches a length of 24 inches or more. This is a widely distributed animal in Eastern North America, and in places it is very abundant. It is recorded from the territory extending from Montreal to Alabama, west to Wisconsin, Kansas, W. Arkansas, and Louisiana. ; It will no doubt be found in all parts of Indiana, but it is very common in the numerous lakes of the northern portion of the State. I have record of it from Lafayette (S. Coulter); Mt. Carmel, Ill. (National Museum) ; New Harmony (Sampson’s coll.) ; Monroe County (Ind. Unv. coll.); Franklin County (Hughes). I have found it common at Lake Maxinkuckee, Marshall County. Prof. Blatchley reports it as very com- mon at Terre Haute. Of 19 specimens sent me by Prof Evermann more than half had the gills very short or almost wholly gone. Hasits.—This species appears to be wholly aquatic, although it does not depend on its gills entirely for the oxygen that it consumes. It has been observed to come to the surface for air; and its gills are sometimes missing, as though nibbled off. In such cases breathing must be accom- plished by other means. They have quite well developed lungs, which some observers have artificially inflated. The animal has seldom been observed to goon land. (54, loc. cit.) In the water they progress either by creeping along on the bottom or by swimming. The swimming is ac- complished mainly by strokes of the large flat tail, and their progress is -rapid. They are, for the most part, nocturnal in their habits. The food of the Water-dog consists of insects, crustaceans, worms and mollusks. They are frequently taken on the hooks of fishermen. They will, no doubt, be found to be willing to eat almost anything that can serve as food. They are not acceptable game to the fishermen, since the latter regard them as very poisonous, and dislike to handle the creatures. _ This notion is an erroneous one ; but a nip by their sharp and strong teeth would no doubt be somewhat painful. Drs. Wilder and Barnard (22, 8, Bre 12» , 438) cooked and ate one, and reported if'as excellent. The animal | might, therefore, possibly be made useful, if people could overcome their } prejudices. ; The Water-dog has the power of enduring long periods of cold and hunger. Kneeland reports having specimens for three months in water that froze more or less every night. Dr. C. O. Whitman states that the egg of Nectwrus is about the size of _ a pea, and, unlike the eggs of most batrachians, it has no pigment to obscure the processes of deyelopment. It forms an admirable object for the study of batrachian development. Large numbers of the Necturus are found in the streams emptying into Lake Michigan and along the shores of the lake. At Ecorse, Michigan, 2,000 were taken in a minnow seine at one haul. It is stated that some of these were so gorged with white fish spawn that when they were thrown on shore the spawn flew out of their mouths. Another man, according to Professor J. W. Milner (Report of the United States Fish Commission, 1872-3, p. 62), had out, at Evanston, Dlinois, 900 fish- — hooks, and from these, in one day, he took 400 of the ‘lizards.’ _ Milner states that they make no more attempt to bite than does a frog. A full series was collected from the Detroit River of specimens ranging from an inch and a half to full grown. About the middle of July eggs ~were taken. 4 “a Family HI. AMPHIUMIDZE.

Color dark slaty or reddish brown, paler below. Lower jaw and edge of upper lip yellowish. The amphiuma may reach a length of three feet. It is found from the Carolinas west to Louisiana. The author has taken it at Little Rock, Arkansas, and has seen a specimen in the National Museum at Washington which was taken at Jeffersonville, Indiana, by Mr. George Spangler. The specimen is fifteen inches long and was received at the Museum Mareh 25, 1880. Careful observations along the Ohio and Wabash Rivers will no doubt result in bringing additional specimens of this interesting animal to light. This, like the Siren, appears to be a mud-loving species. Its whole structure appears to adapt it to burrowing about in the mud at the bottoms of creeks and rivers and ditches.. Its head is long and pointed, and the bones of the skull firmly bound together, as if to render the head the point of a drill. The first instinct of the animal, when put into any vessel, seems to be to burrow ont of sight. This habit of burrowing in mud has been observed ever since the discovery of the creature. Har- lan (39, 86) speaks of them as ‘‘ burrowing in the mud in swamps, or in the vicinity of streams, where it searches for its food and hibernates, occasionally visiting the dry land.” Other specimens are spoken of as having been found several feet beneath the recent alluvial deposit, under the decayed trunk of a tree. The same author (39, 188) states that he ‘had been informed that ‘‘ they are sometimes discovered two or three feet under mud of the consistency of mortar, in which they burrow like worms, as was instanced in digging near a street in Pensacola, when great numbers were thrown up during the winter season.” The food of this animal consists of a variety of aquatic animals. Har- lan says that in the stomach of some were found small fishes and beetles. Holbrook adds to their diet small mollusks. 14 Both Harlan and Holbrook note the habit possessed by this animal of leaying the water occasionally, but the purpose of so doing was not known. No doubt it passes from one water to another in this way, since in can creep readily and does not depend on the water for respiration. The writer has had the opportunity of studying the breeding habits of the Amphiuma. At Little Rock, Ark., on the first of September, a female was found lying in a small excavation underneath a fallen tree trunk in a cypress swamp. The tree was at a considerable distance from any water. Her body was disposed in a coil, in the midst of which was a mass of eggs. In these eggs were young so far advanced that they would soon doubtless have been excluded. The young, which constituted the whole contents of the eggs, were surrounded by a transparent capsule about as thick as writing paper. The eggs were a little more than a third of an inch in diameter, and were connected by a cord of substance simi- lar to that of the capsule itself. This cord varied in length from a fifth to a half inch. ‘There appeared to be two strings in the mass, but of this I was not certain. The whole mass of eggs resembled closely a string of large beads. Of the eggs there were probably about 150. Within the eggs the young were coiled in a spiral. Their length is something less than two inches. Each had three pairs of conspicuous gills, and, since they were evidently nearly ready to hatch, it is probable that they would retain the gills for awhile after entering the water. The gills consisted of a main stem, from which were given off eight or ten branches. Three gill-slits remained open. The eyes appeared to better advantage than they do in the adults. Though the gill slits are probably: present in the just hatched animal, they certainly do not remain long, since Harlan mentions (39, 189) having received specimens of only three inches in length that did not exhibit the least appearance of gills. Not only does the amphiuma exhibit to a remarkable degree, for so low a creature, the maternal instinct, but it is an animal of a good measure of spirit. Dr. Shufeldt (50, 2, 163,) experimented somewhat with the living animal. Into the vessel containing the amphiuma he threw a dead snake. This the amphiuma seized quickly with its jaws and extend- ing itself, began to whirl around rapidly in the water. After the snake had been released, it was again thrown to the amphiuma, and the movements were repeated. When the dead ophidian was presented to the amphiuma the third time no attention was given it. While the female that I captured was still alive, I placed her on a floor and poked her a little with a stick. This she seized, and springing from the floor, she whirled round and round in a spiral form and turned the stick in my hand unless I held it tightly. These animals are remarkable for the size of their blood corpuscles, the largest furnished by any vertebrated animal, since they can be seen eo 4 15 _ by the naked eye. The number of their vertebre is also worthy of re- _ mark, there being altogether about 110, of which sixty-five lie in front of the sacrum. Family IV. CRYPTOBRANCHID. | Form salamandrine.

A total length of two feet may be reached, though usually smaller. Known to occur from Pennsylvania west to Iowa, south to South Car- olina and Louisiana. Not yet known from Florida or Texas. Indiana localities are: Evansville (Nat. Mus.); Whitewater R. at Brookville (E. R. Quick); Ohio R. at Vevay and Madison (Hay.);. New Harmony (Max. von Wied, 103, xxii. 136). It appears strange that the occurrence of this animal has not yet been reported from any part of the State except immediately along the Ohio River, since its extra Jimital distribution indicates plainly that it must be found in all the larger lakes and streams of the State. The ‘‘ Hellbender” is a great coarse, sprawling, repulsive looking creature. In the Ohio and its tributaries it is a common animal, and is cordially despised by the fishermen, whose hooks are too often burdened with it instead of: fish, and who regard it as also poisonous. The latter idea is erroneous; nevertheless, its bite might be painful. They appear to be exclusively aquatic, and yet are capable of living for a long time out of the water. Mr. Charles H. Townsend (22, 16, 139), says that in Loyal- hana Creek, Westmoreland County, Pa., shoals of them may be seen in early spring moving sluggishly over the bottom. In August they appear to hide away under rocks, but will come out after a bait of dead fish. They are very tenacious of life. Mr. Townsend carried some of them in a bag, on horseback, for five miles through a blazing sun, then put them into a tub of water for five weeks without food, and they survived and were vigorous. Mr. Wm. Frear, of Lewisburg University, in corrob- orating Mr. Townsend’s account of their tenacity of life, states that a specimen eighteen inches long had lain in the sun forty-eight hours, then in a museum a day longer, before it was placed in alcohol. After being submerged in this twenty-four hours it was taken out and was alive and vigorous. On making cuts, in the attempt to sever the cervical vertebra, it showed no anger or discomfort; but if only the tip of the tail was touched, the animal would viciously snap its jaws and strike with its tail. Two females of Mr. Townsend’s specimens spawned while in the tub where he put them. The spawn is reported as similar to that of frogs, but without the dark colors of the latter. The ova were exuded in strings, and were farther apart than the eggs of frogs. The eggs were of a yellowish color and surrounded with gelatinous matter, which swelled greatly on coming in contact with the water. Professor Cope states that the eggs are rather large and are attached by two strong suspensors at opposite poles. They must resemble somewhat the eggs of the Amphi- uma, but with soft gelatinous covering. 17 The very young have not yet been seen, so that it is not known whether or not they possess gills. If gills are present on hatching, they must be very transient, at most. Maximillian, Prinz von Wied (103 xxii, 136), states that he found the young of this species at New Harmony. They were about three inches long, had two gill-slits yet open, and remains of external gills. These gills were afterward gradually absorbed. It is possible, however, that these were the young of some Ambystoma, as Professor Cope has suggested to me. ; The Hellbender is said to eat worms, crustaceans and fishes. It will probably eat almost anything that presents itself. Grote states that he has seen these animals with the shed skin rolled up in their mouths, as if in the act of swallowing it. They were observed during July and August to have a swaying motion of the body, but the purpose of this was not discovered. The statement is also made that during the time of pairing of the sexes the tail becomes broader and the lateral folds undergo some changes. The eggs seem to be deposited in the water during the month of August. Professor 8. P. Gage and wife have made the observation that this animal at times draws in water by pharyngeal movements and expels it through the gill-slits. Family IV. AMBYSTOMATIDZ. No persistent gills or gill-slits. Limbs four; digits four to five. Vomers broad, with the teeth on the posterior edge, the yvomero- palatine teeth forming a nearly straight row across the roof of the mouth, in a line just behind the choane. No parasphenoidal teeth. Tongue large, with a narrow anterior and lateral free edge. Carpus and tarsus ossified. Of the Ambystomatide, as here defined, all the species belong to North America, except a single one, and that occurs in Siam. Of the N. A. forms Professor Cope recognizes four genera. Since these genera are founded on peculiarities of structure of the hyoid apparatus, and these require minute dissections, and since all known Indiana species belong to the genus Ambystoma, the others are not defined. The genera recognized by Professor Cope are Amblystoma, Chondrotus, Lingwelapsus and Dicamp- todon. Genus AMBYSLOMA, Tschudi. Figure 1, Plate 1.

Vomero-palatine teeth in a nearly straight, epaieines interrupted, row behind the choanze, Tongue broad, free margin narrow, the upper surface with numerous narrow folds. Tail usually somewhat compressed. As formerly defined, this genus would comprise about eighteen species. As defined by Professor Cope, it will contain still about thirteen species. Of these we certainly have in Indiana six, and possibly more. The Ambystomas are familiarly known as ‘‘ Mud-puppies,”’ and are frequently met with in the operations of plowing, digging ditches and cleaning out cellars. They are often not distinguished from lizards, but the latter are very active, while the former are extremely slow in most of their movements. The Ambystomas, like all similar animals, are — regarded as venomous and are usually destroyed on sight. On the con- trary, they are the most innocent animals imaginable. They can not be provoked to bite; and if they should do so, they have no poison glands connected with their teeth, and the teeth are.so very short that they “could scarcely penetrate the skin. : The species appear to be mostly nocturnal in their habits. Their food in the adult stage consists of insects, small mollusks, and more especially of earthworms. Their winters seem to be spent near the borders of ponds, and in these, as soon as the ice is broken up in the spring, their eggs are deposited. These are surrounded by a mass of gelatine, by means of which they cling to one another and to grass and sticks. The tadpoles are slenderer than are those of toads and frogs, and they have branching external gills. They look a good deal like small catfishes. In due time these tadpoles lose their gills and betake themselves to the land. The larve of some of the species attain a large size before undergoing their metamorphosis, and one ees has been known to breed while still possessing gills. Key ro tHe N. A.

Limbs short and weak, failing much of meeting when laid along the side. Skin smooth and slippery, and with numerous minute mucous pores. The color above is a dark brown or black, paler below. In alcohol there is sometimes a tinge of red. All over the body, but especially along the sides, there are numerous mildew-like specks of gray. The extreme length may become as much as six inches. This species has been found inhabiting the country from Ohio to. South Carolina, and west to E. Kansas and Louisiana. It has also been brought from about Hudson Bay. In some parts of Indiana it is an extremely abundant species. It is the commonest species of Urodele about Irvington. I saw it in Mr. Sampson’s collection at New Harmony. Dr. Ridgway collected it in numbers at Wheatland. It has been taken at Terre Haute by Profs. Evermann and Blatchley, and at Brookville by Mr. A. W. Butler. One specimen in the Terre Haute Normal School collection from How- ard County. I have been enabled to study this species with some care, aid T shall detail its habits somewhat, since they will illustrate the habits of other species of the genus. The Small-mouthed Salamander spends the winter months in and about the borders of stagnant ponds. I have had it taken in midwinter from under ice over which boys were skating. It was captured under such circumstances on January 6, 1886, and again February 6, 1889. These winters were rather mild, and the ice not thick. As soon as the ice is melted they begin to lay their eggs, and it is no unusual thing to have the ponds frozen solidly again after some eggs have been deposited. Some specimens in captivity laid their eggs in the middle of January. Ovoposition more commonly occurs during the month of March. It may continue for a space of at least three weeks. The eges proper are quite small, being about one-twelfth of an inch in diameter. Each egg is surrounded with a capsule of gelatine, which on coming in contact with the water swells up and becomes about as large as a hazel-nut. By means of this gelatinous mass the eggs are cemented to one another and to leaves of grass, sticks, and other objects in the water. The eggs may be deposited singly, but more commonly 4 21 they occur in masses of from two to a dozen, and even more. This gelatine no doubt serves to protect the eggs and the young. I do not be- lieve that any animal will eat the gelatine. Segmentation of the eggs begins immediately, and soon the young salamander may be seen within the gelatine looking like a dark worm. The development of some of the eggs appears to progress more rapidly than that of others. The young escape into the water from the first of April to the tenth. They are then about two-fifths of an inch long, are of a bright olive color, with some squarish blotches along the back. Three little gills stand out on each side of the neck, and on these may be seen rudiments of lateral filaments. The fore-legs are seen as the merest rudiments. I do not think that at this stage they have any mouth. The body is covered with cilia. From the time of hatching there is a club-shaped organ attached just behind each corner of the mouth. These are the ‘‘balancers.’’ By means of these the little animal manages to hang fast to the sides of the vessel, or to objects in the water. They are lost before the tadpole becomes an inch long. When the larva has become a half inch long, its gills have developed two rows of filaments on each stalk. Through these the blood may be seen circulating. Water enters the mouth through the nostrils and passes out through the gill-slits, thus bathing the gills. Larve two-thirds of an inch in length had their intestines filled with the remains of small animals. These consisted principally of entomos- tracous crustaceans. The stagnant waters where the salamanders lay their eggs swarm with minute animal life, and the tadpoles have sharp appetites and the ability to provide for themselves. Later on they seize on small mollusks and insects. When they have become an inch long, they may be seen to come to . the surface after air. This happens more and more frequently as the size increases. When they have attained a size of nearly two inches, the gills begin to show signs of undergoing absorption. They seek the surface oftener, and are inclined to float on the water. They will even leave the water if allowed to do so. The time of completing their change into the adult form is about the first of June. The gills are lost ; the tail loses its fin-like border; the legs have become well devel- oped ; and soon the only difference between the animal and its parents is in size. They betake themselves to the banks, where they are soon concealed among grass roots and earth. About the ponds the adults may often be found concealing themselves under sticks and pieces of wood which lie partly in and partly out of the water. Here they can get an abundance of their favorite food, the earthworms. After their eggs have been disposed of, they appear to leave the vicinity of the water, and scatter out, so that they are only oc- casionally found under logs and in the soil. At this period they do not 29 seem to be able to remain a great length of time in the water, and when left there they have sometimes drowned. I have often been surprised at the ability for climbing shown by these — animals. I have seen them climb up the corners of a zine box six inches high, and make their escape. Indeed, it is extremely difficult to keep them imprisoned. ; The salamander will soon learn to take food when it is offered. They seize and swallow earthworms with great greediness. A worm several inches long will be swallowed by installments. This species of Ambystoma, even in its adult stage, enjoys a sort of aquatic respiration. I have observed them, while under the water, to draw in streams of water through the nostrils and to expel it at intervals through the mouth. These expulsions of water by the mouth occur every eight to twelve seconds. The animal will remain under the water breathing thus for perhaps fifteen minutes. It will then appear to become uneasy, bubbles of air escape from its mouth, and soon it comes to the surface after air. In all probability oxygen is absorbed from the water by the lining of the mouth, and thus the blood is partially purified. In this way we may account for the long time that these animals can remain in water under the ice. This salamander appears to enjoy having its back tickled with a straw. It will often lift its tail high in the air and wave it to and fro in a ludicrous way. It seems at times to make a low piping sound, and at other times produces a clucking noise. : It is of interest to us that this species was first described by Dr. E. Hallowell (7, 1856, 8) as Ambystoma porphyriticum from specimens sent him from Indiana. Ambystoma jeffersonianum, (Green.) Jefferson’ s Salamander. Salamandra jeffersoniana, Green, 1827, 102, 4; Holbrook, 1842, 54, 5, 51, pl. 14; Ambystoma jeffersoniana, Baird, 1849, 2, 283; Amblystoma jeffersonianum, Cope, 1867, 7, 195; Boulenger, 1882, 28, 46, pl. II, fig. 2; Cope, 1889, 57, 101, with figures. A species with an elongated body and head. The distance from the snout to the axilla considerably less than the distance from axilla to groin. Tail equal to distance from snout to vent. There are twelve costal grooves and a dorsal furrow. Skin smooth, but under the lens showing numerous mucous pores. A line of these internal to the orbits. Head rather broad and depressed; its width contained in length to groin from four to five times. Cleft of mouth extending back more than half way to gular fold. Eyes large and set far back. Gular fold prominent, but not = es 25 meeting above. ‘Tongue large and with the papillary folds radiating from behind. Choanz apart same distance as the nostrils. Series of palatine teeth interrupted in the median line and behind each choana, thus making four patches. Limbs long and slender; in some specimens overlapping when laid along the side; in others not quite meeting. ‘Toes long and slender. Tail compressed, narrower above, but without a crest. The tarsal tuber- cles are lacking, or there may be one indistinct. The body varies above from Jead color to brown and black, paler below. On the sides of body and tail, sometimes also on belly, there may be dis- tinct or faint blotches of bluish, but often these are wholly wanting. A length of five to six inches may be reached by full grown adults. Of this species Prof. Cope recognizes three varieties, or subspecies, viz. : Head broad ; its width in length to groin 4 to 4.5 times; lead colored to brown, sometimes with whitish spots. jeffersonianum. Head (as above) 5 times; black, with numerous white spots on sides, belly and tail. laterale. Head (as above) 5 times; uniform lead color. platineum, A widely distributed species, but most common toward the north. Hudson’s Bay south to Virginia and Southern Illinois. Indiana localities : Hanover (Hallowell) ; Irvington (Hay); Franklin County (A. W. But- ler); Wabash County (A. B. Ulrey); Monroe County (Ind. Univ. coll.) ; Terre Haute (Blatchley) ; Lake Maxincuckee, Marshall County (the va- riety laterale). The latter variety with black skin, relieved by numerous © bluish white spots on sides of body and tail and on the belly, and with narrow head, may be expected throughout northern Indiana. It may be distinguished from Plethodon glutinosus by the lack of parasphenoidal teeth. The special habits of this species have not, so far as I know, been studied. These, however, we may be sure, resemble much those of the other Ambystomas; but we may be as certain that they will present some interesting peculiarities. Ambystoma tigrinum, (Green.) Tiger Salamander. ~ Salamandra tigrina, Green, 1825, 2, v, 116; Triton tigrinus, Holbrook, 1842, 54, v, 79, pl. 26; Ambystoma tigrina, Baird, 1849, 2, 284; Ambys- toma mavortia, Baird, 1849, 2, 284; Amblystoma tigrinum, Cope, 4867, 7, 179; 1889, 51, 68, with figures; Boulenger, 1882, 28, 43. This species, as now recognized, is one of the most widely distributed of North American urodeles, being known from Maine to Florida, west to California, and southwest to Mexica. In this wide extent of territory the species has been subjected to a great variety of conditions, and the 24 result has been the production of numerous forms, which differ so much that they have been described as distinct species under many names. The discovery of intermediate specimens has resulted in bringing all the forms under the earliest name, tigrinum. I describe the species as rep- resented in Indiana. . A large, heavily built species, with long tail, stout limbs gud a dark color, varied with numerous yellow spots. Head about as wide as the body, or somewhat narrower in large indi- viduals; the width in the length to the groin about four times. Paratoid region much swollen. Gular fold prominent, overlapping, rising on the sides of the neck. A groove running back from the orbit to the gular fold. Mouth large, reaching back half way or more to the gular fold. Tongue large, with the papillary folds radiating from behind. Vomero- palatine teeth in a straight or slightly curving series across the roof of the mouth, just behind the choanze; occasionally the series projects forward in an angle between the choanz. The body is usually thick and depressed, and looks as if swollen. The distance from the snout to the axilla is contained in the distance from snout to groin two and a half times. There are twelve well marked cos- tal furrows. The tail is commonly equal to the distance from snout to the groin, but specimens are often found in which it is considerably longer. It is flattened and the extremity has sharp edges above and below. — The limbs are stout. There are two distinct tubercles on the sole of the hind foot. The ground color is a livid blue-black, brown, or black on the upper side. Scattered over the body, limbs and tail are numerous spots of bright yellow, which vary greatly in size, shape and arrangement. The spots may enlarge and become confluent, so as almost to cover the upper surface, or they may be almost obsolete. They are not limited to the upper part of the back, as they are in A. punctatum. The belly is of the same color as the upper surface, but it is usually wholly overlaid with sulphur yellow, so as to obscure the ground color. Through this wash of yellow may be seen the still brighter yellow of the spots. The chin and throat are often almost wholly yellow, yet this does not conceal the. still brighter yellow spots. Prof. W.S. Blatchley has shown me a very large specimen from Terre Haute which is mostly yellow, but has on body and tail rather broad anastomosing dark bands. It suggests Cope’s A. ziphias, but lacks the projecting lower jaw and the very long tail. This species is the largest of the genus, individuals sometimes reaching a length of a foot. It is not uncommon to find them from six to nine inches long. Distribution from Maine to Florida, California and Mexico. Indiana localities: Irvington and Indianapolis, rather common; Terre Haute = 25 (Evermann, Blatchley), Crawfordsville (Beachler), Lafayette, very com- mon (F. C. Test); in vicinity of Lake Maxincuckee; Wabash County (Ulrey). Probably to be found throughout the State. The specimens that I have seen from the northern portion of the State have the upper surface less spotted with yellow than usual. This species has probably been more extensively studied than any other of the genus, and this especially on account of the fact that the gills and other larval structures are sometimes retained until the animal has reached the full adult size and even is capable of breeding. Dr. Elliott Coues (9, 4, 290), in speaking of specimens taken in North Dakota, says: ‘‘In all the specimens observed, the metamorphosis from the Siredon stage was completed at a length of four to five inches. In other regions I have procured the same species, still in the Siredon stage, but nearly twice as large.’’ Some interesting observations have been made on the larve of this species by Dr. R. W. Shufeldt (50, 1885, 265 ; 51, 453.) ‘ Dr. P. R Hoy (22, v. 578) states that the Tiger Salamander, early in spring, about April 1,in Wisconsin, repairs to the water for the purpose of depositing its eggs. These are laid in packets of from twenty to fifty, on blades of grass. The eggs, including the gelatine, are a half inch in diameter, the yelk one-eighth. The tadpole emerges in twenty-five days, and has at that time a length of one-half inch. On each side of the mouth is a short ‘‘holder.’? By May 5 the ‘‘holders”’ are lost, the fore legs have made their appearance, and the larva feeds voraciously on aquatic insects. By the middle of August the gills have been absorbed. Thus about 100 days are occupied in attaining the adult condition. Dr. Hoy further says that when the feet and legs have been amputated, as they may be by water insects, they are reproduced, and the digits in the same order as originally. Though I have frequently taken this species about Indianapolis, I have never been able to obtain its eggs nor to recognize the very young. In Indiana the metamorphosis is undergone when the tadpole is about four inches in length. I have seen many specimens taken at Irvington, and these will illustrate the peculiarities of the young at a time just preceding the metamorphosis. The entire length is 4.37 inches. There are present three external gills, each with numerous flat filaments arranged in two rows along the main axis. Three gill-slits are yet open, - and these are guarded by gill-rakers similar to those of fishes. The teeth of the vomers and those of the palatines form separate patches, — and in a series parallel with those of the maxillaries and premaxillaries. The tongue as yet shows no folds. The limbs are well developed. The tail has a broad, fin-like membrane above and below. The upper mem- brane extends forward well toward the head. The upper surface is extensively mottled and blotched with dusky. The color below is white. : 26 On the back are three or four faint cross-bands of dusky. No indica- tions are present of the future yellow spots so conspicuous in the adult. In Indiana this species appears to pass the winter hiding about the margins of ponds, or, in some cases, away from the water, under logs and such places. I have received specimens taken under the ice, in company with A. microstomum, in January and February. Like the latter species, it mostly leaves the water as soon as ovoposition is com- — pleted. They may then be found burrowing in the earth, when they can be found at all. However, this species, unlike A. microstomum, appears to be capable of remaining indefinitely in the water during the summer months and of enjoying its existence there. On the other hand, I haye been told of a specimen that was taken in a dry corn-field on a hot day in August. with figures. A species with broad head, stout body, black ground-color, and yellow spots. Head depressed ; widest at the swollen paratoid region. The greatest width is contained in the distance to the groin from 4 to 4.6 times. From the snout to the gular fold in distance from snout to groin 3.5 to 4times. Gular fold not prominent, but rising high on the neck. Another fold from the angle of jaw running back to gular fold. Eyes of mod- erate size. Mouth large. Tongue moderate, with the papillary folds radiating from behind. Teeth of vomero-palatines in three portions, the extremities of the series being separated from the median portion by in- _ terruptions just behind the choane. The latter openings considerably further apart than the external nostrils. Body plump, with a dorsal groove and 11 (occasionally 10) costal fur- rows. The distance from the snout to the axilla in distance from snout to groin 2.5 times. Limbs moderately developed; when placed along the side, just meeting or not quite. Toes rather short and depressed ; 28 the plantar tubercles indistinct. Tail thick at the base, becoming com- pressed toward the tip, not high, and without a keel; a well-marked depression along each side; usually shorter than remainder of the ani- mal. Skin smooth, but well furnished with mucous pores. A row of enlarged pores along the upper jaw, another inside the orbit, and another on each side of the upper edge of the tail. The general color varies from slate-blue to deep black. There is an irregular row of spots along each side of the back and tail. Similar spots are found also on the head. From head to tail there may be from 10 to 20 of these spots. In alcoholic specimens these spots are white, but in life they are bright yellow. Those on the head are often bright orange, at least in spring. The spots are usually the size of the orbit. Under side of animal paler than above. May attain a length of seven or eight inches. It is distributed from Halifax, N.S., to Wisconsin and south to Geor- gia and West Texas. Indiana localities: Wabash County (Ulrey) ; New Harmony (Samp- son’s coll.); Wheatland (Ridgway); Franklin County (Hughes) ; Wayne County (Butler); Shelby County (G. H. Clark); Monroe County (Ind. Univ. coll.); Irvington; Terre Haute (Evermann and Blatchley). No doubt, exists throughout the State. This species differs from A. tigrinum in haying but eleven costal grooves, but a single series of yellow spots on the upper surface, in the fading of these spots to white in alcohol and in having no plantar tuber- cles, or but a single indistinct one. Like its kindred, this species resorts in early spring to stagnant ponds for the purpose of depositing its spawn. They have been found about Irvington about the middle of March, hiding under pieces of fallen wood, which lie partly in the water. Later they disperse and may occa- sionally be found under logs. Dr. 8S. F. Clarke (122, 1880, No. 2) has studied the development of this species. The’ eggs are laid in masses of from 300 to 400. Each egg is covered with a thin coat of jelly, which swells up when brought in contact with the water. This is supposed to protect the eggs from fishes, but it probably protects them from many other enemies, animal and vegetable. This mass of jelly is much more solid than that of any other species of Ambystoma that Iam acquainted with. While depositing her eggs, the female lies with her fore limbs extended laterally and her hind limbs curved around the opening of the cloaca, as if to assist in holding the eggs together. The male deposits the sperm on the eggs and thus fertilizes them. The egg has a light and a dark colored pole of equal size. Segmentation is most rapid in the light-colored pole. In due time the balancers appear, and are again lost on the thirtieth day. The larva has three pairs of gills, a tail with a —— 29 _ fin-like membrane, and soon develops fore and hind limbs. Its trans- formation to the adult form occurs when a length of about two inches. has been reached. (Cope, 51, 49.) Like the related species, this salamander swims readily by vigorous. strokes of its flat tail, while the limbs are held appressed to the sides. They are often found floating on the water of the aquarium. When disturbed they immediately plunge to the bottom and seek to hide. Their food-habits are closely like those of A. tigrinum. They devour with great greediness the angleworms that one offers them. The worms are swallowed by a succession of gulps. One was observed to swallow three inches of worm in five minutes. Prof. S..W. Garman has observed that the tail is prehensile and employed to prevent the animal from fall- ing. I have observed the same thing. This species, like A. tigrinwm and F z . t 41 The tongue is free all round, as is the case with all of the genus, and can be thrust far out of the mouth. The vomero-palatine teeth consists of two short, curved series, which backwardly approach each other without meeting, and which do not reach the parasphenoidal patches. The latter are separated from each other by a narrow space. The body is elongated and slightly depressed. The distance from the snout to the axilla in distance to the groin nearly three times. There are nearly always fourteen costal furrows, occasionally but thirteen, rarely fifteen. There is a well-defined dorsal furrow. The limbs are rather feebly developed, the outstretched hind limbs are contained in the distance from the snout to the groin about 1.5 times The tail may be a little shorter than the head and body, or a little longer. It is com- pressed, keeled above, rounded below, and ends in a sharp point. The color above is clear yellow, or yellowish-brown, sometimes merely yellowish-gray ; below pale yellow, without spots Along the middle of the back there is a row of small dark spots, and these may even become confluent into a narrow line. Beginning at the eye, there is a dark- brown line which runs backward on the body and tail. The lower barder of this line may be continued down on the side, gradually fading out, however, so that the whole side may appear to be occupied by a broad dusky band. Just below the darkest upper edge of the band, in the intercostal spaces, there may be spots of the ground color. Size, usually about 3.5 inches, although a length of 4 inches may be attained. This species is very widely distributed, being known from Maine to Florida, and west to Wisconsin, and possibly Louisiana. Indiana localities are: Brookville ( Hughes and Butler); Monroe County (Ind. Univ. coll.); Waveland, Montgomery County ( Butler) ; Marion County, abundant at places along Fall Creek, (W. P. Hay); Terre Haute ( Blatchley) ; Vigo County (Nor. Sch. coll.). Some speci- mens from Vigo County have the ground-color, above, a gray merely tinged with yellowish. The snouts of these specimens were also unusu- ally blunt. Similar specimens have been taken in Marion County. Mr. C. 8. Beachler reports the species from Waldron, Shelby County. Like a number of other species, this seems to delight in living in close proximity to the water without spending the whole of its time in that element It is found hiding away under sticks and stones and among dead leaves about shallow streams and rivulets issuing from springs. It is very active and very slippery, so that when it starts away it is ex- tremely difficult to eatch it. A number of adults and larvee were taken June 1, by W. P. Hay, near Fall Creek, in Marion County. The adults were concealed among the dead leaves on the borders of a spring, while the larvee were found in a little pool not far away. The adults were ex- tremely active, and ran rapidly by a kind of combination of wriggling 42 and jumping. The young, which had attained a length of one inch and a half, had all the markings of the adults, except that the color was less yellow. The limbs were developed as in the adults. There were three pairs of gills, which the little animals held erect in the water. The tail also had a broad membranous fin. When the young were disturbed, they would dart through the water with a velocity that was surprising. I was not able to determine what they eat. One of the adults, when captured, had in its mouth the white larva of some dipterous insect. The young show a decided disposition to leave the water long before the gills are lost Both old and young have the ability to climb up perpen- dicular surfaces, Some young were kept in a fruit jar in some water, and it was found that they were dying. All the water was poured out, except a very little, after which they fared better. One was found to have crawled half-way up the side of the jar, and was resting there in apparent content. I have not been able to ascertain the character of the eggs of this sal- amander, nor how they are disposed of. They must be laid in the early spring. Subfamily DESMOGNATHINE. Vertebree opisthoccelian. Carpus and tarsus cartilaginous. This subfamily contains only a single genus, Desmognathus, belonging to which there are three species, only one of which is likely to be found in Indiana. Genus DESMOGNATHUS, Baird. Desmognathus, Baird, 1849, 2, 285; Boulenger, 1882, 28, 77; Cope, 1889, 51, 194. Vemero-palatine teeth in a short curved series behind the choanz;. feebly developed or entirely wanting. Parasphenoidal patches present. Premaxillaries ankylosed. Tongue extensively free laterally and behind, little free in front. Digits 4-5. Vertebree opisthoccelian.* Externally this genus has the characters of Plethodon. It is, however, distinguished from the latter by its vertebree being convex in front, and by the coalescence of the premaxillaries into one piece. A. With 14 costal grooves. «.

Body rather heat built and somewhat depressed. The distance from the snout to the axilla in distance from snout to groin three times, or nearly so. ‘There are usually 14, rarely 13 or 15, costal grooves. A dor- sal furrow commencing at the nape and ending over the vent. Head flat and the snout rounded. The gular fold prominent, rising on the sides of the neck and the turning forward towards the eyes. Another fold, starting on the under jaw, crosses the corner of the mouth and rises on the side of the head. This furrow is crossed by one which starts be- hind the eye and runs back to the gular.fold. The eyes are very promi- nent. Tongue moderate in size, free at sides and behind, little free in front. Vomero-palatine teeth not strongly developed, sometimes en- tirely missing. When present they form only a short series on each side, Parasphenoidal teeth in two patches which diverge backwardly. Lower mandible somewhat undulate, especially in the males; toothed to near the angle of the mouth. Width of head in distance to the groin about five times. The limbs are feebly developed, the fore and the hind limbs, when stretched along the side, not meeting by about four interspaces. Fingers 4, toes 5, jomed at the bases by a narrow membrane. Tail about as long asthe remainder of the animal, tapering gradually to a sharp point; its section at the base circular becoming flattened further back on the upper edge into a narrow fin. The color of this species is quite variable. ‘The adults of full size are usually dark above, with the belly paler, and with mottlings of brown. Along with the brown of the upper surface are shades of gray and pink; the young, and sometimes the half-grown, with ochreous spots along each side of the back, and these bordered more or less with black. In some specimens the whole middle line of the back is yellow or somewhat orange, brightest along the outer border, and divided along the middle line by a row of black spots. Such specimens resemble Plethodon cinereus erythyro- notus. These bright colors are sometimes retained by the full-grown specimens. A variety of this species, awriculata, which bas not been recognized in Indiana, is distinguished by having a series of small red spots along the sides, and often a red spot from the eye to the corner of the mouth. Has been taken near Cincinnati, Ohio. 4 The habitat of this salamander includes the territory extending from Maine to Indiana, Georgia, Mississippi, and southwestern Arkansas. In Indiana it has been taken, up to this time, only at Brookville (Hay- mond, Butler, Hughes), and in Monroe County (C. H. Bollman); Rich- mond (F. C. Test); Decatur County (W. P. Shannon). Where found at all, this species appears to be one of the commonest. It is to a very great extent aquatic. Prof. Cope says that ‘‘ it lives chiefly among the stones in the many shallow rivulets and springs of the hilly and mountainous regions of the country. It prefers the rapid and shallow streamlets. Here it may be found under every stone, or its delicate larvee may be observed darting rapidly from place to place, seeking con- cealment among mud and leaves.” My experience with them is that, while in confinement, they do not, at least during the summer months, remain wholly in the water, but prefer to lie hidden in their tunnels in moss, with the head sticking out, so as to observe what is goingon. When they are lying thus, if an insect is presented to them on the forceps they spring swiftly forward and seize and swallow it. I have had them to take flies and small spiders. One attempted to swallow a nearly whole red-legged grasshopper. They are extremely active and vigorous, and as slippery as eels, and it is with the greatest difficulty that they can be re- tained in the hands. When one is put on the floor, it escapes rapidly by a sort of combination of leaping and running. When held on the hand they will leap from it in the endeavor to escape. The tail is to some ex- tent prehensile, and may be employed to keep the animal from falling. Prof. Baird originally observed that this salamander lays its eggs in a string, and this is wrapped several times around the body of one of the pair, which then retires to a spot of concealment while the eggs develop. This curious habit, about which more needs to be known, has been con- firmed by Prof. Cope. How long the care for the eggs continues is not known. ‘The larve retain the gills for a varying period, but usually until the animal is half-grown. Family VI. SALAMANDRIDA, Body salamandrine in form. No persistent gills or gill-slits. Vertebre opisthocclous. Vomers each with a long palatine process reaching back- ward over the parasphenoid, bearing along its inner edge a single series of teeth. No parasphenoidal teeth. Carpus and tarsus ossified. Our single species red or olive above, with a series of red spots on each side of the back, As here defined, including Professor Cope’s families Salamandride and Pleurodelide. It embraces from six to nine genera, of which we have only the following : ———— — 45 Genus DIEMYCTYLUS, Raf. Diemyctylus, Rafinesque, 1820, 108, 5; Cope, 1889, 51, 202; Molge, Merrem, 1820, 96, 1885; Boulenger, 1882, 28, 6. Vomero-palatine teeth on inner margin of long backwardly projecting palatine processes of vomers. No parasphenoidal teeth. Tongue small, free only a little at the sides. An arch of bone connecting the squamosal and frontal bones. Digits 4-5. ; Diemyctylus viridescens, Rafinesque. Green Triton; Newt. Figure 6, Pl. 1. Triturus (D.) viridescens, Rafinesque, 1820, 108, No. 22; Salamandra symmetrica, Holbrook, 1842, 54, v, 57, pl. 17; Diemyctylus viridescens, Cope, 1889, 51, 207, with figures; Molge viridescens, Boulenger, 1882, 28, 21; D. viridescens, Gage, 1891, 22, 1103, with plate and complete syn- ‘onomy. Body usually rounded and full, without a dorsal crest, but with a dis- tinct sharp vertebral ridge. Distance from the snout to the axilla in distance to groin 25 times. Head longer than broad, its width in dis- tance to the groin about 3.5 times. Outlines of head converging in front of the eyes to the rounded snout. Skull flat above, with four ridges en- closing three grooves; the outer ridge formed by the fronto-squamosal arch, Sides of the head perpendicular. A row of three or four enlarged pores behind the eye; these sometimes wanting. No gular fold. Tongue small and fleshy, free a little at the sides Vomero-palatine teeth in two rows, which meet between the choanz; then, diverging gradually, run backward along the roof of the mouth to the back of the skull. Tail constituting about one-half the entire length of the animal, more or less. compressed, and tapering to a point; in the breeding season furnished above and below with a membrane-like fin. Anterior limbs slender, the inner finger rudimentary. Hinder limbs stout, the inner and the outer toes small. In the breeding season, black callosities appear, in the case of the mature males, on the inner side of the hinder limbs, on the bottoms of the feet, and at the tips of the toes, those above forming transverse ridges. The coloration of this species is so different at different periods of its. life that aspecimen seen while immature and again when full-grown would with difficulty be recognized as belonging to the same species. The gilled larvee are olive of various shades, with black specks above; below, the color is almost uniform whitish. The metamorphosed, but still im- mature specimens are, on the other hand, of an orange color, varying to: 46 vermillion. The belly is somewhat paler. There may or may not be small black specks on the upper surface; while there are on each side of the back about half a dozen crimson spots of the size of the pupil, each surrounded by a black ring. Such young specimens are terrestrial in their habits. The sexually mature individuals are generally of some shade of olive, often having a reddish or yellowish tinge. The lower surface is generally of a bright yellow. Both above and below are to be seen numerous dots of black. In the breeding males some of these spots, especially those on the tail, may enlarge and become more or less ocella- ted. On each side of the ack are the red spots surrounded by a black ring. The red, immature specimens are generally quite rough above and often below through the development, all over the skin, of small, pointed papillee. The distribution of this species is from Maine to Hudson’s Bay, Wiscon- sin, Texas, and Georgia. Indiana localities are as follows: New Har- mony (Sampzon’s Coll.), Brookville, where it is common (Hughes), Mt. Carmel (LL. M. Turner), Monroe County (Ind. Univ. Coll.), Terre Haute (Evermann, Blatchley), Rochester, Fulton County (Dr. Vernon Gould), Lake Maxinkuckee, Marshall County (Hay.) ; The habits of this beautiful and interesting creature have been studied by many naturalists, among them Dr. Hallowell, Prof. S. F. Baird, Prof, E. D. Cope, Dr. Howard Kelly, Sarah P. Monks, Col. Nicholas Pike, and Prof. 8. P. Gage. The red form is so different from the sexually mature, ‘‘ viridescent” form that it was originally described as a distinct species under the name miniatus, and indeed was put by Rafinesque in a different subgenus. Prof. Baird placed the forms in the same genus as distinct species, but he recognized the close similarity existing between the two. Prof. Cope as early as 1859 (1, 59, 122-128), expressed the opinion that miniatus is only a state of viridescens; yet in his check list of 1875 he gives the two forms as subspecies. Later (51, 207) he regards them as ‘‘seasonal forms, which may be by reason of the environment rendered permanent for a longer or shorter time.” Dr. Howard Kelly kept a number of the red miniatus in a dark box filled with wet moss and saw them transform into the olive state characteristic of viridescens. Sarah P. Monks observed the same change. Col. Nicholas Pike kept a number of the red ones where they could enter the water. After some time they did this, and after about three months they lost the bright red color, and in less than a year had the olive hue of viridescens. He, in common with many others, believed that the viridescens form might change back into the miniatus form. Prof. S. P. Gage and wife of Cornell University have studied the species most carefully. They have seen the eggs deposited, watched the hatching of the larvee, their transformation into the red, immature, mini- atus, and the change of other specimens of these into the viridescens. 47 ‘They believe that the terrestrial life continues until the autumn of the third or the spring of the fourth year after hatching, and that when they have once entered the water they do not again leave it unless the pool -dries up or there is a scarcity of food. The eggs are fertilized internally, and, when laid, are glued to the leaves of aquatic plants. Prof. Gage’s observations seem to show that -only about’ six or eight eggs are laid after each pairing of the sexes. After some days another batch may be laid. The time of deposition of the eggs extends from the first week of April until at least the middle of | June. Gage’s statements to the effect that the eggs are attached singly to the leaves of plants is confirmed by the observations of Cope and Monks. Prof. Verrill, of Yale College, and Col. Pike, on the other hand, state that the eggs are laid in masses containing from 25 to 150. ‘The larve are active and timid. Their heads are not so broad as those of the larvoe of the Ambystomas, with which they may be associated. Their food consists of minute crustaceans, larval insects, and small snails. In color and form they closely resemble the full-grown individuals, except that they have three plumose gills, and the broad tail-fin extends forward to the back of the head. The gills begin to be absorbed during the last half of the August after hatching, the tail-fin is absorbed, and the larvee then often comes to the surface to obtain air. About September 1 the now transformed young leave the water, hide away in the dirt and among leaves, and acquire the yellow or red color. During the metamorphosis the body appears to shrink considerably in size. I have seen, in the Na- tional Museum, a number of specimens, 2.25 and 2.75 inches long, with remains of gills, while red specimens, 1.75 inches long, entirely without any trace of gillsare common. Prof. Gage, however, finds that the larvee are usually only about an inch and a half long at the time of their change. Where found in abundance, the adult newts may be taken during all the warmer months of the year; and it is probable that they are active during the whole year, unless the cold is too intense. They have been seen swimming under ice an inch thick. They delight most in pools which are fed by perennial springs. Their habits are not so nocturnal as those of many of their kindred. They may be seen at all times of day swimming about, climbing on aquatic plants, floating on the surface of the water, and basking in the sunshine. The food of the adults consists of insects, tadpoles, worms and mollusks. In confinement they become quite tame, and will take pieces of beef or insects from a wire, opening the mouth slowly, protruding the tongue, and gently pulling off the mor- sel. One has been known to swallow a piece of earthworm twice its own length, and to use its hands in holding its prey. During the breeding season the colors are most intense, and the sexes are at their best. The spots along the sides become flame-color, the belly orange, while the male acquires a broad spotted crest along both edges of 48 the tail. At the same time the black callosities appear on the hind legs. In their courtship the males are very active and very ostentatious. When success is won, they seize the female around the body and remain thus for an hour or more. Prof. Gage finds that the sexes pair in the fall as well as in the spring. The outer skin is frequently shed. It is pushed back from the head by rubbing against objects; sometimes the hands are employed to effect this purpose. The process of moulting occupies about an hour and a half. Samuel Lookwood (22, x, 11) has seen it free itself of the cuticle while under the water; immediately the little thing turned around and swallowed the whole skin. Prof. Gage has seen the terrestrial form pull the exuvium off the end of the tail and swallow it. It is also interesting that the Newt can utter a faint shrill cry. The tail is extremely prehensile, and may be employed to suspend the animal for some time. It has been observed by Prof. Gage that during the aquatic stages the epithelium of the mouth is of the non-ciliated variety, while during the miniatus stage the epithelium is ciliated. Furthermore, the adults, while living in the water enjoy a form of aquatic respiration, water being regularly taken into the mouth and again expelled. Order SALIENTIA. Batrachia having a frog-like, or toad-like form. All four limbs present, the hinder greatly developed and fitted for leaping. Proximal elements. of tarsus elongated, so as to form an additional limb segment. Vertebree_ in front of the sacrum not exceeding nine. Ribs rarely present. No tail in the adult state. A tympanic cavity present. This order includes the frogs and toads. With rare exceptions, the eggs are laid, fertilized, and hatched in the water. The young are familiar to all as tadpoles. These breathe for a short period by means of external gills, and for a longer time by internal gills. The intestines are long, the mouth furnished with horny sheaths, and the lips with several rows of horny teeth. By means of these, the little tadpoles are enabled to sup- port themselves by scraping off the minute vegetable matter which covers. objects in the water. As growth progresses, the limbs develop; the fore- limbs, however, are for a long time concealed beneath the skin, and when they break through, they appear to be produced suddenly. As the period of metamorphosis approaches, the horny jaws and denticles are shed, the- mouth enlarges, the tongue appears, the intestine shortens, the tail is absorbed, respiration by the lungs prevails, the gills disappear, and the tadpole leaves the water and becomes a frog. All regions of the world, except the very coldest and the very driest, furnish representatives of this Order. Altogether there are about 800 49 species described. All our species come under Prof. Cope’s suborders Arcifera and Firmisternia. Of the first, we have representatives of two families; of the second, one family. Key To tHe Famiures or Salientia. A.

Immediately behind the orbits each of these is met at right angles by a crest, the postorbital, which runs outward ‘and down- ward behind the eye. From the lower end of the postorbital, a ridge, the supra-tympanic, may pass backward over the tympanic disk. Snout short and blunt, the outline in front of the nostrils perpendicu- lar. Tympanic disk distinct, oval, smaller than the eye. Upper jaw notched in the middle line. Paratoids elliptical, about as long as the distance from-the nostril to the postorbital crest.

Skin on the upper surface everywhere provided with large and small pointed warts; below rough with crowded, pointed granulations. Color variable; usually olive to brown, with irregular blotches and spots of dark brown; middle of the back with a light streak; below dirty yellow. The upper surface is sometimes almost a uniform black ; at other times ash-gray, showing the dusky spots with great distinctness. Occasionally a specimen is found with the tubercles, and even considera- ble portions of the skin of a beautiful pink color. Other specimens may be of a uniform brick-color above, pink below. Males provided with a large vocal sac, which communicates with the mouth by a slit on each side of the tongue. The toad may reach a length of as much as five inches, including head and body. Females larger than the males. Four varieties, or subspecies, of this animal are recognized by Prof. Cope, three of which may be looked for within our borders. They may be distinguished as follows: Fronto-parietal crests lying closely together, parallel, posteriorily pass- ing little if any beyond the postorbitals. No supra-tympanic crest; a pre- ‘orbital ridge. Heel reaching beyond the muzzle. Size rather small. Color grayish-olive ; vertebral line yellow. fowleri. 51 Fronto-parietal crests diverging toward back of head, and passing some- what beyond the postorbitals. The latter crests short; preorbital not strong; no supra-tympanic. Heel reaching the front of the orbit. Our common form. americanus. Fronto-parietals diverging toward back of head, passing beyond the postorbitals and expanding into a pair of knobs; supra-tympanic well developed. Head from snout to ends of crests contained in length to vent 3.5 to 4 times. Southern. lentiginosus. The common toad in its various forms has an extremely wide distribu- tion, being known to occupy the whole of eastern North America, west to Montana, Arizona, and Mexico. In Indiana the variety americanus is everywhere distributed. The variety lentiginosus has not been reported from any locality within the State, but may be looked for in the extreme southern portion. The variety fowleri is known principally from speci- mens found at Danvers, Mass., but Prof. Cope reports a specimen from New Harmony. (See 51, 279.) The toad is with us an extremely common animal. It is almost a synonym for ugliness, but its mild and inoffensive disposition has gained for it some degree of toleration. Nevertheless, it still suffers much per- secution, chiefly at the hands of untaught and thoughtless or cruel boys. The toad appears in the spring when the warm days have fully come, and it is seen until the approach of the cool days of the autumn. Soon after emerging from its winter retreat, it repairs to the water for the pur- pose of depositing its eggs. These are laid, not as those of the common frog, in a shapeless mass, but in a long string, consisting of a double series of eggs enveloped in a tube of gelatinous materials. Mr. E. E. Crosby (22, vii, 574) says that the eggs of two specimens numbered re- spectively 8,840 and 2,200. Prof. Cope states that the young hatch early and are of a darker hue than is usual with other Salientia, but it is difficult to see how they can be blacker than the larve of Rana pipiens. The length of the young mature toads is about one-half inch; the color gray- ish, with small dark-colored spots. The metamorphosis occurs about July 10. The notes of the male toad are heard principally during the breeding season. They may be represented by the syllables ur-r-r-r-r, The habits of the toad are mostly noctural, although it is not uncom- mon to see a toad hopping about in the daylight. Usually, however, they hide away during the day in holes and obscure corners, and come forth at evening to seek their food. This consists mainly of insects, and of these enormous numbers are devoured. It is related (34, 73, 23) that one old toad ate at one time twenty-three squash bugs, and on the top of these, ninety-four caterpillars. On account of this propensity for devouring in- sects, intelligent gardeners and farmers seek to induce toads to take up their residence on their grounds. No boy should be permitted to destroy this harmless animal. The prey is taken by suddenly projecting the ay tongue from the mouth, and then withdrawing it with the insect sticking to it. Besides insects, toads will eat earthworms, and small crustaceans, while it is said that one attempted to swallow a wounded humming bird. When the prey is large and difficult to swallow, the toad is said sometimes to push it against the ground or a stone. One is described as pressing its hand against its stomach, in order to hold down an earth worm that. threatened to escape. The toad is stated never to make leaps after its prey, but to await until it has approached near enough to be reached by the tongue. The warty skin of the toad is full of large glands, which secrete a thick whitish fluid. This has very acrid properties, and doubtless serves to render the animal unpalatable to most of its enemies. It does not. seem, however, to protect it from snakes. It is said that this secretion will make the mouth of dogs sore, and even to cause some inflammation of the human skin. This last is doubtful. The skin of the frog is shed at intervals, and the statement has been made that this skin is immediately swallowed. During the winter the toad hibernates in holes and in the mud. Dr. J. A. Allen, of Cambridge, Mass., tells of some toads that were taken in a torpid condition from the mud at the bottom of an old well. Some of them were buried in the mud two feet deep, and he supposed that they had been there ten or fifteen years, and probably longer. On: ° being taken out, they soon revived and hopped away. Family VUI. HYLID&. Upper jaw with teeth. Fingers and toes furnished with disks; these supported by the claw-like, terminal phalangeal bone. Transverse pro- cess of sacrum expanded. Vertebrze proccelous. According to Prof. E. D. Cope, this family contains 183 species, and these he includes in 18 genera. They are distributed in all the great faunal regions. Of these genera, we have only three. Key To THE GENERA OF Hylide FouND IN INDIANA. Fingers without a web. Toes fully webbed. Digital disks small. Aeris, p. 53. Fingers webbed or not.

Length of head, measured to hinder edge of tym- panic disk, in the length of body to vent three times. Snout pointed, its length in length of body six times; projecting beyond the lower lip. Vomerine teeth in two patches between the choane. Tongue broad, ovate, with or without a notch behind. Males with a large gular sac, which opens beneath the tongue. Tympanic disk seen with difficulty, Skin of the back smooth, or with small or’ large tubercles. Belly and thighs granulated; throat smooth. Legs long, the heel passing near to or beyond the snout. Two large metatarsal tubercles. Subarticular tubercles well developed. Fingers without web; toes webbed to near the tips. Color variable and subject to rapid changes. Usually the upper sur- face is ashy-gray or brown. Occasionally green predominates, or there is considerable of reddish, especially along the middle of the back. Between the eyes there is a triangular spot of dusky, bordered with green in life. The middle line is usually pale. The upper lip is spot- ted with black. There is a blotch of dusky from the eye to the shoulder, and a stripe of the same above and behind the fore legs. Legs cross- barred Color below, white; under jaw often dusky. The length of large specimens is a little over one inch. * Foor-NotE.—This character may easily be observed by making a transverse incision in the skin of the back at the point where the iliac bones are connected with the vertebral column; that is, where the frog’s back bends abruptly. The transverse process cleaned of tissue, may then be compared with the same structure in the Common Tree-frog, Hyla versicolor. 54 Two varieties, or subspecies, of this frog are recognized, as follows: Skin of back nearly smooth; hind foot from metatarsal tubercles: longer than half the length of head and body. gryllus. Skin of back considerably tuberculated| Hind foot, from the meta- tarsel tubercles, shorter than one-half the length of head and body. erepitans. The habitat of this species extends from New York to Florida, and west to Nebraska and Texas. The variety gryllus is, for the most part, Southern in its range, while crepitans is more Northern. In Indiana the erepitans is found everywhere. The variety gryllus is in the National Museum from Mt. Carmel, on the Wabash, and I have specimens taken at Lake Maxinkuckee which correspond well to the descriptions of that variety. This little frog is one of our commonest batrachians. During the sum- mer season it may be seen in numbers along all of our streams. I doubt if it is often seen about the ponds or pools far from running water. It is not thoroughly aquatic, but delights to spend its time amid the vegeta- tion about the border of the water. When alarmed it will leap into the water, but it often appears to become alarmed at its rashness and hastens to reach the Jand again. When followed up, however, it will go to the bottom and seek to conceal itseif for awhile. Though belonging to the ‘‘tree-frogs” it never ascends trees, and probably climbs only the shorter . grasses.and water plants. It is a cheerful little creature, and on warm days may constantly be heard executing its noisy song. This resembles closely the striking together rapidly of two pebbles, and often, when their singing has been interrupted by the passer-by, it may be started again by clicking two stones sharply together. This little chatterer appears very early in the spring, and it is my ob- servation that it is to be found at all times during the summer. Numer- ous specimens were found at Irvington on the 8th of March. The eggs are probably laid about this time, although I do not know anything about them. On the 16th of August I found numerous specimens of the tad- poles of this species. They were found hiding in the vegetation at the bottom of a small stream. They were in very different stages of devel- opment, some with both the fore and the hind legs visible, others with only short hind legs. The arrangement of the horny denticles about the mouth of the larvee I found to be different from that of specimens of Chorophilus triservatus. In both species there are two rows of horny den- ticles on the upper lip. On the lower lip, there are in the Chorophilus three rows of denticles, but in Acris only two. Furthermore, in Choro- philus the denticles are finely serrated at their tips; in Acris this is not the case. The teeth of the latter genus are less numerous than in the former. The transformations occurred about September 1. Dr. Holbrook states that the Cricket frog feeds on various kinds of 5d insects, and makes immense leaps to secure its prey and to escape pur- suers. He says that it can be easily domesticated, and takes its food readily from the hand. He kept several of them for months in a glass globe on a few sprigs of purslane, feeding them occasionally with flies; their chirp was at times incessant, and sprinkling them with water never failed to render them more lively and noisy. Dr. C. C. Abbott (22, xvi, 707) has studied the habits of this species in New Jersey. He found them extremely abundant along ditches through meadows in the early spring, and very noisy. The eggs were deposited in little masses about May 1, and attached to blades of coarse grass. After the eggs were laid the number of frogs rapidly diminished, and by June 10 all were gone. Dr. Abbott believes that all die, and that those which appear later come from the transformation of the tad- poles. This occurs late in August. The frogs seem to be moderately abundant about the middle of September, but they are then found along rapidly flowing brooks. He also thinks that the frogs do not eat during the autumn, while in the early spring they are extremely voracious. In this region I have found them during the whole summer, notably in August before the tadpoles of the year have transformed. Genus HYLA, Laurenti.

The digits all provided with disks of larger or smaller size. Vomerine teeth present. Tongue entire or notched behind. Tympanum usually distinct, sometimes hidden.

Head considerably broader than long; the snout rounded; the space in front of the eye concave. Eyes Jarge and protruding. Tympanic disk about two-thirds the diameter of the eye. Tongue large, circular, notched behind. Vomerine teeth in two closely approximated patches lying between, or a little behind, the chone. Chest crossed by a broad fold of skin. Fingers and toes with disks nearly as large as the tympanum. Fingers with an evident membrane uniting them. Toes webbed to near the tips. The first finger opposed to the rest. On extending the hind leg along the side the heel attains the back of the orbit. Upper surface with numerous smooth warts; belly and under surface of thighs granulated. Males furnished with a large gular sac which opens on each side under the tongue. The color in life varies from olive to dark gray and green, varying with athe surroundings of the animal. Between the eyes there is a V pointing (backwards. On the back there is a large, somewhat cruciform blotch of dark color, and behind it another smaller blotch on each side. The limbs 57 are marked with broad bars of brown. The groin and the front and back of the thighs are bright yellow, over which is a network of brown lines. The gular sac of the males is often brown. The length of a large specimen, head and body, is sometimes two inches. This species occurs from Maine to Minnesota, and south to the Gulf and Texas. It is not necessary to specify localities in our own State. Prof. Cope has recorded a variety of this species from Mt. Carmel, Ill., under the name of phwocrypta. ‘‘ The color is a dark brown, with three rows of large approximated darker brown spots.” Thighs yellowish brown, with little darker brown. Hasirs.—This species is by far our commonest representative of the Hylide. Although not often seen, it is heard by all, especially during the early spring. The time of appearance in the spring varies with the lati- tude and the weather. About Indianapolis I have heard them as early as the middle of April, and they may come from their winter quarters even earlier. Their breeding habits have been described by Mary H. Hinckley, as they are displayed in Massachusetts (43, xxi, 104 and 309; 22, xvi, 636). The adults emerge from their places of concealment from May 1 to 10. The eggs begin to be deposited immediately, and this pro- ceeds until July 4. The eggs are attached singly or in small groups to the grasses growing in the water near the shores. These eggs have ex- tremely little gelatinous matter around them. The development of the tadpoles goes on with great rapidity, being accomplished within forty- eight hours. When hatched, the tadpoles are a quarter of an inch long, and of a pale yellow color, dotted on the head and sides with olive. Later the olive hue prevails, and there are markings of gold. The external gills appear and are resorbed during the first week. The ‘‘ holders” disappear within the first ten days. The tadpoles do not huddle together. The hind legs appear at the age of three weeks. At that time the belly is iridescent, the back metallic, and the tail may be of a bright red. Soon, however, the color changes to a greenish, aud by the time the met- amorphosis has been completed, the color is a bright green. The arms appear during the eighth week. At this time they eat little food. They abandon the water from the 19th to the 24th of July, and their size is small. They betake themselves immediately to shrubbery and ascend it. They were seen to catch small spiders and to eat plant-lice. Some that were kept in a fernery gave evidence that they are nocturnal. Their green color is retained for about three months, when the frogs become gray. The black markings are not developed until after the young have forsaken the water. The Tree-frog has a loud voice and may be heard during damp weather. It passes its time on trees, fences, and among vines, and it has the power of adapting its colors to the objects among which it lives. 58 The changes are said to occur slowly. These changes of color enable it. to escape the notice of its enemies. These frogs appear to hibernate sometimes in the earth and sometimes in crevices in trees. Hyla squirella, Bosc. Squirrel Tree-frog. Hyla squirella, Bosc, 1802, 57, ii, 181; Holbrook, 1842, 54, iv, 128, pl. 80; Boulenger, 1882, 27, 398; Cope, 1889, 57, 363, with figures. A species of small size, the length seldom exceeding an inch and a quarter. The body and limbs slenderer than in either H. versicolor or H. pickeringu. The snout is somewhat pointed; eyes prominent ; tympanum about one-half the diameter of the eye. Vomerine teeth between the choanz. Head broader than long. Fingers without web; toes half-webbed. Heel reaching in front of the eye. Skin of the upper surface smooth; of the belly, thighs, and sometimes of the chin and throat, granulated. Color above in life said to be green; below, white. In spirits, light. brown or purplish. There is a V-shaped mark joining the eyes and several scattered spots of the size of the tympanum on the back. A dark band from the snout to the eye, thence through the ear to the shoulder. Below this there is a narrow light line. Limbs indistinctly barred. The snout of this species is less projecting than in H. pickeringii; the tympanum larger and more distinct. Until recently this species has been known only from South Carolina and west to Louisiana. Recently, however, a specimen was sent to Professor Cope by Mr. Amos W. Butler, from Brookville, Indiana. This gives a remarkable extension to the range of the species. Of this frog Holbrook says that it is found on trees, often seeking shelter under the bark of such as are decayed. It frequently chooses old logs for the place of its hibernation. He had often seen them about old houses and under logs and boards. Hyla pickeringii, (Storer). Pickering s Tree-frog. Hylodes pickeringii.

Head a little longer than broad; snout rather pointed; the canthus rostralis distinct; the loral region concave. Interorbital space wider than the eyelid. Tympanum distinct, about half the diameter of the 59 eye. Tongue free behind, rounded and slightly notched. Vomerine- teeth in two patches, a little behind the choane. Males furnished with a large gular sac, which opens into the mouth by a slit each side of the tongue. Fold of skin on the breast conspicuous or not. Fingers and. toes with well-developed discs. Fingers entirely without webs. Toes: half webbed. Hinder limb, when pressed to side, bringing the heel to the eye. Two distinct tubercles on the heel; subarticular tubercles present. Skin nearly smooth above, granulated on the chest, belly and the under surface of the thigh. Color above varying from ash to brown and reddish. On the back is an X of narrow dusky lines, these beginning at the eyes and terminating on the sides just before the insertion of the thighs. On each side of the body, opposite the intersection of the lines of the X, begins another dusky line, which runs parallel with the corresponding line of the X. Between the eyes is a very open V. A dusky band runs from the snout to the eye, and seems to be continued over the tympanum and the fore leg, and fades out along the side. Edge of the upper lip pale, but mottled with dusky. Some specks of brown on the breast and throat. Gular sac of male brown, at least in the spring. Fore legs of the color of the body, and with indistinct bars. Thighs mottled, tibie barred, feet mottled. The young frogs, with bodies three-fourths of an inch im length, are of a fine straw color, with the usual brown markings. Length a little over one inch. Known to occur from Maine (78, 707) to Manitoba and south to South: Carolina and Indiana. Specimens of this frog have been taken in the vicinity of Bloomington by the late Charles H. Bollman. Professor Blatchley reports having taken four specimens at Terre Haute, and there was a specimen from there in the Normal School collection. I have it also at the hands of Mr. A. B. Ulrey, from North Manchester, Wabash County. I have also received a specimen from Brookville, at the hands of Mr. Ed. Hughes. It will, no doubt, be found ultimately in all por- tions of the State. Prof. Cope states that this is our most abundant species of Hyla, but that it is more generally known by its voice than by its appearance’ “* After the rattling of the Acris gryllus in the marshes and river banks is fairly under way, during the first bright days of spring, the shrill ery or whistle of this little creature begins to enliven the colder swamps and meadows of the hill country. Different individuals answer each other with differently toned voices of a single note. This is exceedingly shrill and loud; the muscular force employed in expelling the air from the lungs seems to collapse the animal’s sides till they nearly meet, while the gular sac is distended with each expulsion to half the size of the head and body together. They are chiefly noisy in the end of the afternoon, but in shady situations or on dark days may be heard through the morning 60 and noon. When the breeding season is over they may still be found, but with difficulty, among fallen leaves in low places, where their color admirably adapts them for concealment, or in cellars, or on the ground in the woods. Not till the near approach of autumn do we have evidence of their ascent into the trees. Then, when the wind is casting the first ‘frosted leaves to the ground, a whistle, weaker than the spring cry, is heard, repeated at intervals during the day, from one part of the forest to another, bearing considerable resemblance to the note of the purple finch, uttered as it is while flying. These voices are heard during the same season, that of the Hyla being distinguishable as slightly coarser, or more like a squeak. Both are associated with the weak chirp of the late Den- _dreca coronata as it gleans its insect food on its southern flight. These are the latest sounds of autumn, and soon disappear before the steady advance of the ice king.” (Cope, 51, 354.) DeKay (30, 69) says that this species is abundant in the neighborhood of New York, and that they are often to be seen on Indian corn and grape vines, and in greenhouses, under the leaves of plants during the heat of summer. He says that they feed on small flies; but it is not probable that they restrict themselves to such small creatures. Mr. S. P. Fowler sent the editors of the American Naturalist a beautiful fawn-colored spec- imen, which he had found imbedded in a heap of grass in his garden on November 25. The eggs are laid in bunches of from 4 to 10, and are about one-twelfth of an inch in diameter. The eggs and larve in various stages of devel- opment are figured by Prof. Baird in Cope’s ‘‘ Batrachia of N. A.” He states that the eggs are laid May 15. Smith says (18, 707,) that in Maine the eggs are deposited in April. According to Prof. Baird’s state- ments, the young are able to swim within four days. For further details on breeding habits see Miss Hinckley’s paper in Mem. Bost. Loc. Nat. Hist., vol. v, pp. 311-318. Some larvee of pickeringii which I have examined in the National Museum, at Washington, and which had the tail of full size, were a little less than an inch in length. Other young which had just transformed were only seven-sixteenths inch long. Prof. Blatchley reports finding this frog at Terre Haute, April 8, at the margin of a pond, to which they had evidently resorted in order to deposit their eggs. Two were kept in captivity several weeks, and regularly at 8 p. M. they began their piping notes, and kept them up about an hour. After this they were silent until the next evening. The gular sac would be inflated until it was two-thirds _as large as the animal itself, when the air would be forced out, pr oduetng the notes. (94, 91, 27.) 61 Genus CHOROPHILUS, Baird.

Limbs of quite variable length, the heel reaching only to the tympanic disk, or to the nostril. Skin almost everywhere granulated, finely on the back, more coarsely on ‘the lower surface. General color, varying from light ash to fawn and purplish-brown ; below, cream color. On the back and sides there may, in nearly all specimens, be seen five dark stripes or rows of spots. One beginning on the head, runs along the back, often forking on the urostyle. On the head, this stripe may expand so as to involve the eyelids, or there may be spots on the lids distinct from the median stripe. On each side of this dorsal stripe is another, which begins behind the eye and ceases just in front of the thigh. Another stripe begins on the snout, runs through the eye, over the tympanic disk and the shoulder, and fades out along the side. A whitish line runs along the upper lip to the shoulder. Sometimes the median and the lateral bands next it may be broken up into distinct spots, or these bands may be obsolete. The limbs are more or less barred or spotted with dusky. _ Under the name nigritus I have included forms which are assigned by Prof. Cope to three distinct species, nigritus, feriarum, triseriatus. I do so because, at the present time, I do not think that the distinctions are sufficiently constant to characterize species. That the student may recognize the forms and accord them specific value, if he so desires, I state the differences. Snout acuminate; width of head in length of head and body 2.8 to 3 times; heel reaching in front of orbit; size larger; color leaden or fawn, with three rows of dark spots above; these sometimes united into con- tinuous bands.

Snout shorter; width of head in the length 3 to 3.25 times; heel reach- ing to front of orbit; length of body in total length of hind leg, from 1.40 to 1.70; color ash or brownish, eyelids involved in median stripe, ‘three parallel stripes above, seldom interrupted. Eastern United States to Illinois. feriarum. Snout drawn out; width of head in length 3.5 to 3.6 times; heel reaching only to tympanic disk; length of body in total length of hind leg, 1.24 to 1.50 times; color ash to brown, with three parallel dark stripes, the median often forking behind; a distinct spot on each eyelid. New Jersey to New Mexico and Idaho. triseriatus. C. nigritus is chiefly or wholly southern, feriarum eastern, and triseria- tus, the short-legzed and peaked-nosed form, mainly western, in distribu- tion. All that I know of from Indiana belong to the variety feriarum. These have been taken at Brookville (Ed. Hughes), Brooklyn, Morgan County (W. P. Hay), Wheatland (Nat. Mus. coll.); Irvington; Terre if 63 Haute (Blatchley), New Harmony and Mt. Vernon (Max. von Wied, 103, xxii, 118); Wabash and Kosciusko counties (A. B. Ulrey). This species appears to be rather rare in Indiana, but its rarity may be more apparent than real, since many of these animals have the faculty of effectually concealing themselves from the eye of the collector. In Indi- ana the variety feriarum lays its eggs about the 20th of March. The writer has described the life history of this little frog (22, xxiii, 770, with plate). Its eggs were found in a small pool on the 22d of March. They were attached to twigs in small and large bunches. Each egg was one- third inch in diameter, including the usual coating of jelly. In the egg the larva has a strong dorsal flexure, and has the tail thrown over the back. The tadpoles were set free on April 5. They are slenderer than the larvee of the Leopard Frog, and not so dark in color. They are dark gray, rather than black. The external gills are small and quickly ab- sorbed. They spend much of their time sticking to objects by means of their ‘‘ holders,” but very soon these organs disappear, and they then anchor themselves by means of their sucker-like mouths. The rudiments of the hinder limbs appear about the 20th of April. At the same time two rows of horny teeth appear on each lip, and a few days later an addi- tional row on the lower lip. These teeth are minutely deticulated at their tips, and they form an admirable apparatus for scraping off the layer of nutritious slime that covers all objects in the water. There are from 55 to 95 of these teeth in each row. : As the tadpoles grow older the body becomes broader and the tail acquires a broad fin. By April 20 the length has become one half inch, and by May 4 about three-quarters. The body is of a dark color, adorned with numerous blotches of gold. The belly is nearly covered with a shimmer of gold and coppery. When three-fourths inch long the young were observed to come to the surface and to take in air. By the 20th of May the young have attained the total length of a little over an inch. Many of them about this time succeed in releasing their forelegs from the skin which has held them down. Now the tadpoles grow smaller instead of larger. This is largely due to the shortening of the intestine at this period of transformation. These four-legged tad- poles are very lively and very timid. They show a great inclination to get out of the water and to hop about. They soon lose their skill in swimming, and if confined to the water too long will drown. The disks are seen on their fore feet as soon as these feet appear. The tails are rap- ddly absorbed, and by the 12th of June all have become little frogs like the adults, except in size. At the time of transformation the length of the head and body is less than one-half inch. This species, though called a tree-frog, probably never climbs trees. ‘They seem to live on the ground among the fallen forest leaves and in the grass. Prof. Oope states that it will leap into the water when alarmed, 64 but will not stay there long. He also describes the note of triseriatus,. which I have not heard. It is said to resemble that of the Cricket Frog, although not so loud. It may be imitated by drawing a point strongly across a coarse comb, holding them at the bottom of a jar and bringing them rapidly to the top.

A very common, widely distributed and variable frog. Head varying in relative length, being contained in the length of head and body from 2.5 to 3.5 times. Vomerine teeth in two slightly oblique patches between the choanze. Tympanum about as large as the eye. Heel reaching to the muzzle or a little beyond. A pair of prominent dorso-lateral folds starting behind the eyes and running to the end of the body. Between these may be two or more thinner folds. None of these folds are as broad as those of R. palustris. Another glandular fold runs from the corner of the mouth to the shoulder. No, or an inconspicuous, branch meeting this from the dorsal-lateral fold behind the tympanum. Ground color ashy, olive or bright green above; below uniform white or yellowish. The upper surface with a number of rounded or oval brown spots of small to medium size, and these usually bordered with yellowish. The spots between the dorso-lateral folds are larger, and may be arranged in two or three rows, or may be irregularly placed. Outside these folds are two or three rows of smaller spots. The upper surfaces of the limbs are more or less conspicuously barred or spotted. Length of head and _ body of full grown specimens three to four inches. Most of the males of this species have vucal sacs, which open by # small slit near the angle of the mouth. These sacs appear to be pro- truded through the slits, and serve to render the voice more powerful. Of this species Prof. Cope recognizes four subspecies, three of which may occur in our region. It must, however, be understood that forms inter- mediate are likely to be found. Head long, contained in the length to vent 2.5 to 3 times; snout long and pointed ; males with external vocal vesicles; heel reaching be- yond tip of snout; web of foot leaving three phalanges of fourth toe 5 66 free; spots of small size, scarcely bordered with pale; no longitudinal band on the front of femur. Mostly in Southern States. sphenocephala. Head of medium length, contained in length 3 times; snout pointed ; males with vocal vesicles; heel reaching tip of snout; web of foot leaving two phalanges of fourth toe free; spots of medium size, bordered with pale color; femur with a longitudinal band; tibial bars divided into two rows of spots. Maine to Mexico, but mostly in E. U. S. pipiens. Head short, contained in the length 3.5 times; snout obtuse; vocal vesicles rudimentary ; web of foot leaving nearly three phalanges free; spots larger and widely bordered with yellow; cross bars of tibia com- plete; no longitudinal bar or femur. Maine to Oregon and Mexico, but mostly Western U. 5S. brachycephala. This species, as represented by its different varieties, is distributed all over the eastern portion of the United States and west to Oregon, Nevada and Mexico. The variety sphenocephala is chiefly southern in its range, pipiens (virescens of Cope) eastern and northern, and brachycephala west- ern. Neither is confined, however, to these limits. With us the common form is pipiens, and it is everywhere abundant. Sphenocephala is in the National Museum from Wheatland, Ind., and to this I refer one specimen from Lake Maxinkuckee, which I find in the collection of the State Nor- mal Schoo]. One specimen in the same collection and taken at Camden, Carroll County, had some of the characteristics of brachycephala. The head is contained nearly 3.5 times in the total length. Three specimens brought from Wabash County have the length of the head in length of head and body only 2.66 times. These might be referred to sphenocephala. The Leopard Frog is our commonest, best known, and most beautiful frog. It is likewise the one tliat first makes its appearance when in the early spring the ice has relaxed its hold on the waters of our ponds and streams. Its cry is one of the earliest of the vernal notes. Indeed, it is no unusual thing, during an open winter, to hear its croak during the warmer days of midwinter. Its notes are of a varied kind. Prof. Cope says that its voice may be imitated by the syllables chock, chock, chock ; but at times it has a cry that sounds like derisive laughter, and again, a sort of low, querrulous tone. Dr. Garnier (22, ’83, 949) speaks of its ‘‘lugubrious and dismal love notes.” Soon after it leaves its winter quarters, it proceeds to lay and fertilize the eggs. These are extremely numerous, and are laid in great masses, consisting of the small eggs en- veloped in a large quantity of jelly. One pole of the egg is white, the other black. I have record of the deposition of the eggs at Irvington on March 18, and of the escape of the larvee by April 1. The latter are five- sixteenths inch long; of this one-half is the broad tail. The numbers of these to be seen sometimes in ponds is astonishing. These tadpoles grow rapidly and transform during the first summer of their lives. 67 This frog is exceedingly active, and is capable of making leaps of 8 to 10 feet. They frequent ponds and streams, but they also leave these and ‘travel to considerable distances in the search of suitable food. When thus traveling about they are much exposed to the attacks of snakes. “Their intense green color must serve them well as a means of concealment from their enemies. Like other frogs they pass the winter buried in the ‘mud at the bottoms of ponds and streams. Rana palustris, LeConte. Swamp Frog. Rana palustris, LeConte, 1825, 62, i, 282; Holbrook, 1842, 54, iv, 95, pl. 23; Boulenger, 1882, 27, 42; Cope, 1889, 57, 406, with figures. This species is very closely related to Rana pipiens, and especially re- sembles the variety brachycephala The head is relatively longer than in the variety last named, being contained in the length of head and body 3 times. The snout is usually obtuse, although not always so. Vomerine teeth in two nearly transverse patches between the choane. The tym- panum is about two-thirds the diameter of the eye. The males have no external vocal vesicles, although Boulenger says that they have internal vesicles. The glandular folds of the back are especially well developed, being unusually broad. Of these the dorso-lateral are most conspicuous. They begin at the upper eyelid and run back to the hinder end of the body. Nearer the middle line and just behind the eyes two other folds begin, but appear to die out near the pelvic hump. Their places are there taken by two folds which lie close to the urostyle. All these folds are breader than in specimens of Rana pipiens. Above the tympanum the dorso-lateral fold gives off a branch which curves down behind the tym- panum and meets another fold starting at the mouth and terminating at the shoulder. The hind leg contains the length of the body 1.66 times. When the leg is pressed to the side the heel reaches the snout, or somewhat less. The web is deeply scalloped, and on the fourth toe leaves three phalanges free. ‘The tubercles of the palm and of the sole are greatly developed. The ground color is a pale brown or ashy above; below, yellowish white. Nearly the whole of the upper surface is covered with squarish spots of dark brown. The dorso-lateral folds are of the ground color. Within these there are two quite regular rows of the quadrate spots; the interspaces of these are much narrower than the diameter of the spots. Sometimes two or more of these spots coalesce so as to make a band. ‘There is a spot on the snout and another on each eyelid. Outside ot’ the dorso-lateral folds on each side is a row of spots like those of the back, but somewhat smaller. Lower down on the side is still another row of smaller and more irregular spots. On the upper jaw is a white streak 68 from the snout to the shoulder. Upper and lower lips are mottled. The arms are spotted. The hind limbs are conspicuously barred from the groin to the toes. The posterior surface of the thighs is bright yellow, spotted with brown. This species is found from New Brunswick west to Iowa, and south to: Louisiana. It has been reported to me as occurring at Brookville (Hughes), and at Bloomington (Bollman). I have not seen the speci- mens from either of these places. In the State Normal School collection are two specimens that were taken at Lake Maxinkuckee. I have two specimens taken at Irvington, which I refer to this species with some doubt. I have been able to learn little about the special habits of this frog. Prof. Cope tells us that it is a more solitary frog than R pipiens, that it prefers cold springs, and that it is seen in the grass more frequently than any others of our frogs. Its note is likewise said to be a low prolonged croak, somewhat resembling the sound of tearing some coarse material. Some authors tell us that it has a strong, disagreeable smell. Rana areolata circulosa, R. and D. Hoosier Frog. Rana circulosa, Rice and Davis, 1878, 67, ed. ii, 355; Cope, 1889, 51, 413, with figures. Rana areolata, as defined by Prof. Cope, is made up of four subspecies. Of these three belong to the Southern States, the fourth, circulosa, was. originally described from specimens taken in Benton County, Ind. The species is characterized by a large, broad head, a short leg, imperfect pal- mation, and its peculiar coloration. The length of the head is one- third or more of the length, and its breadth is equal to, or greater than,. its length. The leg, when pressed to the side, brings the heel only to the eye. The web is deeply scalloped and leaves three phalanges of the fourth toe free. Above, on each side, is a strong glandular fold, and be- tween these there are several thin folds. In circulosa the head is one-third of the length to the vent, and quite flat. The tympanic disk is oval or circular and only one-half the diameter of the eye. Between the dorso-lateral folds are six to eight narrow folds, and these may disappear in alcohol. The striking thing about these frogs is their coloration. The spots found on the upper surfaces of their relatives, R. pipiens and palustris, have here become so expanded that they cover nearly the whole area. The ground color of yellowish is reduced to a network of narrow lines, or circles. Posteriorly in large specimens the lines of the net-work are broader and browner, and have a border of a lighter color. The spots. themselves are of a reddish brown color. No light streaks about the 69 head. Upper lip marbled with brown and yellow. Fore limbs mottled. Hind leg, including thigh, tibia, and foot, with wide bars of dusky and very narrow interspaces. Below, the color is uniform yellowish. Found in northern portions of Indiana and Iliinois. Described origin- ally from a specimen which was found in Benton county, Indiana, by E. F. Shipman. About the size of R pipiens, but one specimen in the National Museum is nearly five inches long from snout to vent. Rana clamata, Daudin. Green Frog. Rana clamata, Daudin, 1803, 69, 104; Boulenger, 1882, 27, 36; Cope, 1889, 51, 419, with figures; Rana clamatans, Holbrook, 1842, 54, iv, 85, pl. 20. Head broad and flattened, contained in the length of head and body about three times. Snout rounded. Eyes large and _ protruding. Vomerine teeth in two patches, the posterior edges of which project behind the line joining the hinder borders of the choanz. Tympanic disk usually as large as the eye, sometimes larger; occasionally, especially in the females, somewhat smaller than the eye. A groove passes from the back of the eye over the tympanic disk and downward behind it, and terminates in front of the arm. There are present two dorso-lateral glandular folds. These start at the upper eyelids and run back to the pelvic region. Over the tympanic disk a branch is given off which passes down behind the disk and terminates over the arm. The groove described above lies between the disk and the branch. The skin of the back and sides is more or less rough.~ This roughness is produced by minute, sharp-pointed, wart-like elevations, those along the sides largest. Hind limb, when pressed to the side, bringing the heel between the eyeand snout. Third toe longer than the fifth. Toes webbed nearly to the tips. Subarticular and one metatarsal tubercles moderately devel- oped. Color above varying from greenish olive to brown; in life often bright green toward the head. On the back there are usually numerous small nearly circular blotches of dark brown, and larger ones on the sides. These are not spots, light bordered and definite, as those of R. pipiens, but look as if the color had run into the surrounding skin. The hind legs are crossed by narrow bars or rows of spots. The hinder surface of the thighs is granulated and of a yellow color, with spots and mottlings. of black. The lower jaw and throat are marbled with brown, otherwise 70 pale below. This species may be distinguished from R. catesbiana by the- presence of the two dorsal folds. The length of head and body may be: ° greater than three inches. Distributed over the Eastern United States at least to the plains. Found all over Indiana in abundance. This frog is thoroughly aquatic and lives along streams, in pools and in cold springs. It probably never leaves the water to travel any con-- siderable distance. It is rather solitary, never collecting in such numbers as do the individuals of R. pipiens. They are timid, and when surprised by the stroller they leap, with a cry, into the water. Its voice may be represented by the syllable ‘‘chung.’’ DeKay states that its- note is more sonorous and in a lower key than that of the Bull-frog. The tadpoles of this species require two years for their development. Before the tail has been absorbed this species may be distinguished from larvee of the Bull-frog by the presence of the dorsal glandular folds. When the fore limbs have appeared, the total length of the tadpole is about two. and a half inches. The larve are stated to live on soft vegetable sub- stances and never to be carnivorous. Rana catesbiana, Shaw. Bull-frog. Rana catesbiana, Shaw, 1802, 77, iti, 106, pl. 27; Boulenger, 1882, 27, 36; Cope, 1889, 51, 424, with figures; Rana pipiens, Harlan, 1825, 47, 62; Holbrook, 1842, 54, iv, 77, pl. 18 (not of Gmelin). Attaining the largest size of any of our frogs, the body becoming in. some cases 8 inches long, and the length of head, body and legs 18 inches. Head contained in the length 3 times or less; usually somewhat broader than long; sides of head sloping outward; snout rounded. Vomerine teeth projecting little behind the choanze. Tympanic disk the size of the eye or even larger. Skin of the back smooth or minutely rough. Heel reaching to the front of the eye. Fourth finger slightly longer than the first. Third toe longer than the fifth. Toes webbed to the tips. There are no dorso-lateral glandular folds. A glandular fold begins at the upper eyelid, runs over and behind the tympanic disk, and in front of the arm, ending on the breast. Between it and the tympanic disk is a sharp groove. The color of the upper surfaces in aicohol varies from reddish to olive and brown. In life the color may be pale yellow, green, brownish, or even deep brown. Below, the general color is white or yellowish. On the upper surface spots of brown may occasionally be almost entirely missing, but generally there are blotches of brown varying in size and number, sometimes running together. Their outlines are not well. a . 71 marked. The sides usually with distinct marblings of brown. The thighs may be spotted as well as the rest of the leg and foot. The lower surfaces may be almost devoid of any brown markings, or they may be conspicuously present on throat, breast, belly and legs. The hinder part of the thighs is usually mottled and blotched. Distribution, Eastern North America to the Rocky Mountains. Every- where in Indiana. This species lives in the waters of our brooks, rivers and lakes. It probably never strays away from the vicinity of the water in the search of food. Its loud voice has given it its popular name of ‘‘ Bull-frog.” Prof. Cope says that its notes may be imitated by utturing a bass ‘‘br’wum” several times in a hoarse voice in front of an empty cask. Dr. J. H. Gardnier (22, 1883, 954) says that he has heard the Bull-frog” at a distance of 5 or 8 miles. Authors tell us that when this frog is whipped it will cry much like a child; and Dr. Gardnier says that he has known the Bull-frog to hold its mouth open and scream for more than a minute, like a child in distress. These frogs are very voracious, and seem to catch and swallow almost any living thing that they can pos- sibly devour. They have been known to eat cray-fishes, small fish, insects, worms, snails, mice, and even their own species. One was observed to be trying to swallow another of about half its size. Prof. J. A. Allem tells us that one seized and swallowed a cedar bird which he had shot, although the wings and tail continued to protrude out of the frog’s mouth. Dr: Jos. Jones, of Georgia, reports having found in the stom- ach of one that he dissected a ‘‘ grass-snake” three feet long. Other cases of the latter kind are on record. The tadpoles of these frogs, like those of R. clamata, require two years for their complete development. It is possible that in some cases @ greater number of years is passed in the larval state. A larva of this species was found to have a total length of 4.5 inches, of which 2.8 was tail. The general color above was dark olive green, below yellowish white. This species is the one that is most relished as an article of diet. The frogs are often caught with hooks baited with red flannel. Rana sylvatica, LeConte. Wood Frog. Rana sylvatica, LeConte, 1825, 62, 282; Holbrook, 1842, 54, iv, 99, pl. 24; Boulenger, 1882, 27, 47; Cope, 1889, 51, 447, with figures. A rather slender and graceful frog, with a broad head and long legs. Length of head contained in the length of head and body from 3 to 3.5 times; its width greater than its length and contained in body and head 72 2.5 to 2.75 times. Snout rather pointed, the canthus rostrales distinct. Eyes prominent. Tympanic disk about two-thirds the diameter of the eye. A dorso-lateral glandular fold starts at the corner of the eye and continues along the side to near the vent. Over the tympanic disk it gives off a rather indistinct branch, which bends down behind the disk and terminates over the arm. There are no folds between the dorso-lat- erals. Another glandular fold begins at the corner of the mouth and stops just over the arm. The skin of the back, the sides, and upper sur- faces of the legs is provided with numerous minute sharp points, which produce a slight roughness to the sight and touch. The hinder surface of the thighs somewhat granulated. Other surfacessmooth. Legs long, the heel reaching to the muzzle or beyond. Tibia longer than the femur. One metatarsal present. The subarticular tubercles feebly developed. Web leaving two phalanges of longest toe, and one of the others, free. Length of head and body may be about 3 or 4 inches. In alcoholic specimens the color of the upper surfaces of body and limbs varies from pale reddish-brown to ashy or dark gray; the sides may be pale yellow or brown; beneath whitish. There may bea few indistinct spots on the pelvic region of the back, while the sides may be somewhat mottled with dusky. Lower surfaces occasionally indistinetly marbled. Limbs distinctly or indistinctly barred with brown. A dark stripe at the base of the humerus in front. A black stripe from the snout to the eye. A triangular brown ear patch. A white stripe from the snout and along the upper lip to the arm. Upper and -lower lips marbled with brown and whitish. One specimen in my possession, captured at Irvington, has a light streak from snout to vent, reminding one of R. catabrigensis. In life the colors are variable. One was gray above, the back with a tinge of green, while the hind limbs had a tinge of weddish. The dark ear-patch was overlaid with a tint of copper. Iris golden. The glandular folds were golden-yellow, the flanks yellowish- green. Another living specimen was of a reddish or pink color every- where above. In life the color is liable to undergo rapid and consider- able changes, according to the surroundings. This species occurs from Maine to the Athabasca River and south to ‘South Carolina and Missouri. It is doubtless to be found everywhere in Indiana. Localities which have furnished specimens are as follows: Marion and Shelby counties (Hay); Franklin County (Hughes) ; Monroe County (Ind. Uniy. coll.) ; Montgomery County (A. W. But- fer); Hamilton County (F. C. Test); Terre Haute (Evermann and Blatchley ); Wheatland (R. Ridgway ); Wabash County (A. B. Ulrey). This, it appears to me, is our most delicate, beautiful and interesting species of Rana. It is far less aquatic than the others, preferring to spend its life among the fallen leaves of the forest. It is not often seen, but occasionally occurs in enormous numbers. DeKay (30, 64,) says 73 that Dr. Kirtland informed him that they were so abundant in the woods of Ohio that it was almost impossible to move without stepping on them. With us, at the present day, they are far less abundant. They are extremely active, and when pursued, they escape by making great and quickly repeated leaps. They are very skillful in hiding, and the close resemblance of their colors to the dead leaves and grass surround- ing them renders it extremely difficult to find them. One that I was after leaped into the water and hid along side of a stone, and although I knew almost exactly where it was, it was some time before I could recognize it. Miss Hinckley has studied the habits of the breeding adults and of the young (43, xxii, 91; 22, xviii, 151). These frogs congregate very early in the spring for the purpose of ovoposition, although they are not able to move in water below a temperature of 45° F. There may be as many as 1,380 eggs in one mass. The time of development varies greatly according to the temperature. The external gills were devel- oped within two days after hatching, and in four more were wholly absorbed. ‘The metamorphosis of the tadpoles was prolonged from April 12 to June9. Tadpoles, which on May 31 measured 58 mm. in length, became reduced after the metamorphosis to 18 mm., about three-fourths of aninch. It was first observed by Prof. S. F. Baird that the tadpoles of this frog are carnivorous. He says that one way of preparing the skel- eton of small animals is to put them in a vessel of water containing the living tadpoles of some of our frogs. These will devour the macerating flesh and leave the bones cleaned and hanging together by the ligaments. The larvee of R. sylvatica are, he said, the most effective. CLASS II. REPTILIA. Members of the Class Reptilia pass their lives under extremely various conditions and circumstances. Many, as the larger number of the turtles, some snakes and the crocodiles, are given to haunting the waters of the sea, or of the rivers, lakes and ponds. Others, such as most snakes, and many tortoises, and the lizards, spend their lives on the land, and some of them in the hottest and most arid situations. Their eggs, even those of the most aquatic species, are always laid on the land; and the young, though they may, immediately after they are hatched, betake themselves to the water, never have gills, and depend wholly on their lungs for the oxygen that enters their blood. Their form is from the first like that of the adults. In nearly all cases the epidermal layer of the skin of reptiles is disposed in the form of scales or plates. These may, on the one hand, be so small as to form mere granules, or, on the other hand, they may consist of a few large plates, like those of most tortoises. The soft-shell turtles, however, furnish us with an exception to the rule given. The epidermis of these is soft and moist, and is not broken up into definite areas. When limbs are present they are made up of the same elements as those of Batrachians, Birds and Mammals. But many reptiles, such as the snakes and many lizards, are entirely devoid of limbs. The blood of reptiles is cold, the heart has only three chambers (except in the crocodiles), and the arterial blood, as it is distributed to the body, becomes more or less mixed with the venous blood. As to their reproduction, most lay eggs; others bring forth their young alive, the eggs being retained in the body until the young have reached a considerable size.

The Ophidia form a large and important order of Reptiles. They inhabit all the great faunal regions of the globe. They are few in species in the colder portions of the globe, but swarm in the hotter and moister regions. They are divided by naturalists into a large number of fam- ilies, but of these we have representatives of only the following three: 76 Kry TO THE NATIVE FAMILIES OF OPHIDIA.

Ventral plates 112 to 131; ‘subcaudals 24 to 36 pairs. Scales smooth and glossy, arranged in 13 rows. Color above, rich chestnut brown, below yellow to salmon. Length not exceeding one foot. The specimens without prefrontals have been re- garded as belonging to a distinct species helene. Prof. Cope has shown recently, however (3, 1892, 596), that this is an inconstant character, and that the forms must be united. The species is distributed from Massachusetts to Georgia, and west to Central Arkansas. Indiana localities are: Wheatland (Ridgway); New Harmony (Sampson’s coll.) ; Monroe County (C. H. Bollman); Brown ‘County (Chas. Jameson) ; Crawford County (Hay), where in the vicinity of Wyandotte Cave several specimens were found hiding under stones and logs; Terre Haute (Blatchley). Some of the specimens from New Harmony and those from Wheatland belonged to the form with pre- frontals; all the others were without prefrontals. 79 Little is known about the habits of this innocent little serpent. DeKay states that it is found hiding under logs and stones. Mr. Sampson, of New Harmony, told me that he found it under the dead leaves in the forests. Its movements are probably nocturnal. Holbrook adds that it lives on insects. Dr. J. A. Allen states that it is decidedly subterrestrial in its habits, and is more frequently turned up by the plow or hoe than seen crawling on the surface. It seeks to bury itself when thus exposed. ‘Observations on the breeding habits are needed. Genus FARANCIA, Gray. Farancia, Gray, 1842, 73, 68; Baire and Girard, 1853, 6, 123. Head slightly distinct from the body. Crown-shields eight, the pre- frontals being united. No anteorbital, the postfrontal and the loral en- tering into the orbit. Two postorbitals.

A snake reaching a large size. Head scarcely distinct from the body. ‘Crown-shields normal, except that the prefrontals of the opposite sides are fused into one. No anteorbital. Loral and postfrontal forming an- terior border of the orbit. Rostral low. Nasal single, groove below the nostril. Postorbitals two. Upper labials 7, the eye over 3d and 4th. Lower labials 8 or 9. Scales smooth and shining; arranged in 19 rows. Ventral plates 171 to 203; subcaudals 35 to 47. Anal plate divided. The ground color may be regarded as blue-black. The sides are marked with about sixty transverse bands or wedges of bright red, which in some cases extend nearly t» the middle of the back. These bands sometimes extend downward to the middle of the belly, and either join or alternate those of the opposite side. Since the red has definite margins and con- trast strongly with the black, the belly has a checkered appearance. The head above is dark blue, with the plates tinged with red on their margins. Upper labials red, with a blue spot on each. This snake reaches a large size, contrasting in this respect with its rela- tives, Carphophis and Virginia. One mentioned by Mr. S. Garman is 54 inches long, of which 5.6 is tail. This species is distributed from South Carolina to Louisiana and Central Arkansas, and up the Mississippi Val- ley to Knox County, Indiana. It and its eggs have been sent from 80 Wheatland to Mr. Robert Ridgway, of the National Museum. It, has alsc been taken in Illinois just across the Wabash River from Indiana. Ihave seen it at Little Rock, Arkansas, in a cypress swamp. Holbrook says of this species that it is rare and shy, and that it lives in swampy ground and in damp places. It is a beautiful snake, as beauty goes among snakes, Genus VIRGINIA, B. & @. Virginia, Baird & Girard, 1853, 6, 127; Garman, 1883, 73, 96, in part.

Originally described by Kennicott from specimens obtained ‘‘ in heavily timbered regions in Southern Illinois.” In my possession is a small spec- imen that was taken by the late Charles Jameson, of Indianapolis, at some point in Brown County. The total length is 5.75 inches. +From this I draw a description. Head small, narrow, and relatively high. Snout pointed, and the sides of the head perpendicular. Vertical hexagonal, with its right and left sides parallel. Occipitals large. Prefrontals entering the orbit and with the lorals forming its anterior border. Upper labials 6, the eye over the 4th and 5th. Scales in 17 rows; smooth, except that those on the tail are feebly keeled. Ventral plates 120; subcaudals 45. Color gray, with a tinge of purplish, especially on the head. Below yellowish white, possibly reddish in life. On the dorsal surface are to be seen, here and there, small black dots. Those on the upper surface and the sides of the head more numerous and resembling points made by a fine pen. From Brown county, Indiana, to Indian Territory (10, 84). Nothing appears to be known about the distinctive habits of this deli- cate little creature. It must live on the smallest insects and worm-like creatures. Its subdued colors will undoubtedly enable it to escape the notice of its enemies. Its near relative, Virginia valerie, has not yet been found in Indiana. —.. 81 Genus BASCANION, B. & G. Baseanion, Baird and Girard, 1853, 6, 938. Baseaniwm, Cope, 1875, 12, 40. Size large, form elongated; head distinct from the body; narrow and with sides perpendicular; tail long. Crown-shields 9.

Bascanion constrictor, Baird and Girard, 1853, 6, 93. A long, slender snake, with a distinct head and a slender, whip-like tail, which constitutes about one-fourth the entire length. Head long, pointed, high; crown flat, and with the face bent down in front of the eyes. Eye in a groove which runs forward to the nostril. Snout pointed and rather projecting. Rostral high. Upper anteorbital large, the lower verysmall. Upper labials 7 or 8, the large eye over the third. and fourth. Lower labials 8 to 10, sixth very large. Rows of dersal scales in 17 (rarely 15 or 19) rows; the scales very smooth, the median narrow, the outer broad. Ventral plates 171 to 190; subcaudals 80 to 110. The color of the adults is uniform above, but varies according to age and varieties from lustrous pitch-black to lead color and yellowish olive. Length 6 feet or more. In its varieties or sub-species this species: has a range from the Atlantic to the Pacific and south to Mexico. Variety constrictor. . Lustrous pitch-black above, varying to lead color. Below, the color is greenish-white or slate color, with the middle line paler. There is more: or less white on the chin and the lower jaw. Upper labials with some white. Specimens from the prairies of the West and Southwest are of an olive-green color, and such shade into the variety flaviventris. The colors of the young Black-snake are so different from those of the adult that one would hardly suspect it to be the same species. Instead of being of a uniform color above, they are much blotched and spotted- There is a series of reddish-brown blotches with black borders along the middle of the back, but disappearing on the tail. The blotches are about three scales long, and reach down to about the fourth row of scales. 6 82 on each side. The sides are furnished with many specks and spots of brown. The intervals between the spots are grayish or olive. The head is mottled and specked. Below, the color is greenish-white, with three or four specks of brown on each scale. Specimens over 18 inches begin to assume the coloration of the adult. The range of this variety is from the Mississippi River eastward. It is to be found in all portions of Indiana, and it is unnecessary to specify localities. No species of our snakes is, probably, better known, or, at least, more talked about, than is the ‘‘ Black-snake’”’ or ‘‘ Black-racer,’”’ or, as it is often called, the ‘‘Blue-racer.’? This is true probably because of its abundance in all localities and because of its bold, active, and aggressive disposition. It is, however, somewhat confounded with another common Black-snake, Coluber obsoletus, which does not appear to be nearly so active or so saucy. The systematic name of this snake, constrictor, was given in allusion to its supposed habit of entwining itself about the limbs and bodies of per- sons whom it might see fit to attack. Gmelin, one of its early deseribers, speaks of it as running with great velocity, biting without poison, attack- ing men by entwining itself about their limbs and squeezing. This is a widely spread idea concerning these snakes at the present day, and there is no doubt some truth in it. However, their daring is greatly exagger- ated, and the stories that we may hear everywhere about their squeezing people to death are without sufficient foundation. If one of these snakes were driven to bay, or were seized, there is little doubt that it would defend itself with great vigor and promptness. These serpents are not without wisdom, and it is a common reputation which they have that they will sometimes pursue persons who are retreating, but when the latter turn the snakes will seek safety in flight. They are evidently full of curiosity, and will often follow persons or objects, apparently merely to observe them. I have been told of one of these snakes which was in a meadow where a mowing machine was at work. The noise of the mower appeared to excite the reptile greatly, and it followed the machine around the meadow several times. At last it became so wrought up that it sprang over the sickle bar and was cut into pieces. It is possible that in this case the animal had young ones in the vicinity. Prof. Blatchley says (94, 91, 31) that they are vicious, and will hiss and strike at a trespasser when they are seeking a hiding place for the winter. DeKay states that it isa bold, wild, and untameable animal, and that it climbs trees with great ease by twining itself around the trunk in a spiral manner. This it does in quest of eggs and the young of birds. Hol- brook says that it feeds on mice, toads, and small birds. It is bold and daring, entering barns and outhouses without fear, and has been known to destroy young chickens. He also reports it as very irascible during 83 ‘the breeding season, and that it will attack persons who may pass it, even -at a distance of several steps. Its tail quivers with rage, making a quick, vibratory motiou, which among dry leaves sounds not unlike the whir of the rattlesnake. It will even descend trees in order to attack an enemy who may tease it. He never knew one to try to twine jet about the legs, as it is commonly supposed to do. Besides eating such creatures as have been already mentioned, the black-snake sometimes attacks and devours other snakes. Mr. F. W. Cragin (22, xii, 820) states that he found a black-snake swallowing a striped snake, Eutainia sirtalis, which he had killed the day before. The black-snake was 42, the striped-snake 22 inches long. This was a case in which the reptile was driven to partaking of cold victuals. Prof. A. E. Verrill, of Yale College, writes (22, iii, 158) that a student of Yale caught a large black-snake, and in bringing it home alive by the neck smothered it so that it became sick and vomited up a copperhead snake two feet long and in a nearly perfect condition. Soon afterward this was followed by a good-sized frog. Prof. Verrill supposes that the black-snake -caught the copperhead while it was trying to swallow the frog; but this supposition is by no means necessary. Black-snakes are known to attack and destroy rattlesnakes in open fight. The black-snake is said to circle around the rattlesnake until the latter becomes confused or thrown off his guard, and then to spring suddenly upon the poisonous reptile, encircle him in its folds, and squeeze him to death. Dr. Elliott Coues (9, 4, 269) speaks of the hostility existing between the black-snake and the rattle- snake. In one case reported the black-snake threw two or three coils of its tail behind the rattlesnake’s head and several others further back, and then, by a powerful muscular effort, tore the rattlesnake in two. When the black-snake has thus triumphed he has a right to a full meal. They are known to eat other species of snakes (22, ii, 136). When one snake swallows another the head is taken into the mouth first. A snake can swallow another almost as large as itself. H. A. Brons, writing (22, xvi, 566) of the habits of some western snakes, says that this species and some others have the habit of swal- lowing whole eggs, and that it is no unusual occurrence to find such ‘snakes with the entire contents of quails’, prairie hens’, and domestic fowls’ nests in their capacious stomachs.» With a little trouble they may be compelled to disgorge the ingesta unbroken. Miss Hopley, in her interesting book on snakes, says that these snakes will eat eggs, and that they will drink milk and eat cream. But when people tell us that they will suck the cows we must draw the line broadly and distinctly. In the fall, and sometimes probably also in the spring, these snakes collect together often in large numbers, and we hear occasionally of “‘balls’’ of snakes having been seen. Brons, cited above, says that the female of the ‘‘ Racer’’ is the larger, and not so graceful in form or 84 movements. During the season of love making she seems to toy with the male, at times darting through the grass, among stones and into- crevices to avoid him. On clear, level ground she is at a disadvantage. There, if she attempts to quit him, a coil of his tail is thrown about her body and his head laid upon her neck, and if it is removed, as promptly replaced, in the evident endeavor to propitiate her. Later in the sea- son they are solitary or live in pairs. The eggs of the black-snake are an inch and a half long and an inch in diameter. They are covered with a thick, tough skin. Out of such an egg I took a young snake 10.5 inches long. The snout was blunt, while a little sharp tooth projected from the middle of the upper jaw, beyond the lip. (See Agassiz 4, 1, 288; Dr. Weinland, Proc. Essex Inst. ii, 28.) This is an ‘‘ egg tooth,’’ and its purpose is to enable the young to rip open the tough egg coverings when the time for hatching has come. This tooth is shortly afterward shed. Just the time of lay- ing the eggs and the special way in which the female disposes of them. I have not been able to learn. They are in all likelihood hidden away in soft earth or in rotten wood. In one female I found nineteen eggs, of which seven were in the left oviduct. Genus DIADOPHIS, B. & @. Diadophis, Baird & Girard, 1853, 6, 112; Garman, 18838, 13, 60.

A snake of small size, having a head distinct from the body, and a tail about one-fourth the total length. Head flat, snout rather broad and projecting beyond the lower jaw. Rostral low and broad. The lower anteorbital small. Upper labials seven or eight, eye over third and fourth, or fourth and fifth. Lower labials eight, fifth largest. Scales smooth, arranged in fifteen rows. Ventrals 148 to 205. Sub- caudals 36 to 60. 85 The color above varies in the subspecies, or varieties, from olive through gray to blue-black; below from yellowish white to orange and red, with more or fewer dark spots. There is usually a light ring around the neck, close to the head. The form usually found in Indiana is the typical punctatus The color above is a bluish black or a dark ash, with a wash of bronzy that extends down to the lowest rows of scales. Below, the color is orange or deep red, somewhat palest in front. On the outer ends of each of the ventrals there is a small black spot, and these are involved in the color of the dorsal scales. Near the middle line of the ventrals may be two rows of dark spots, or the spots on the ventrals may unite to form transverse bars. The ring around the neck is orange, edged with black. It is one or two scales in width. Upper labials yellow. The length may become about fifteen inches. This form is distributed from Nova Scotia to Georgia and the Mississippi Valley. Indiana localities are New Harmony (Sampson’s coll.) ; Franklin county (Hughes); Monroe county (Bollman) ; Mont- gomery county (a specimen brought me by Mr. Beachler); Terre Haute (Blatchley); Shades of Death, Parke county. Hasrrs.—Not much can be said concerning the habits of this little snake. Holbrook says that it is a very timid animal, living a great part of the time under the bark of trees, or old logs and stones. It emerges from its hiding places toward the dusk of evening, or after rain, when the insects on which it feeds have been washed from their hiding places. DeKay tells us (30, 39) that it is perfectly inoffensive, and that it emits a disagreeable odor. I can find nothing concerning its breeding habits. Genus CYCLOPHIS, Giinther. Cyclophis, Giinther, 1858, 26, 119; Garman, 1883, 13, 39; Chlorosoma, Wagler, 1830, 75, 185; Baird and Girard, 1853, 6, 108. Form moderately elongated and slender. Head distinct from body.

Body and tail rather long and slender, but less conspicuously so than in Phyllophilophis estivus. Tail forming seldom more than one-third the 86 total length, usually one-third or one-fourth. Head narrow and mod- erately high. Snout somewhat projecting beyond the lower jaw. Mouth- cleft large, curved. Upper labials 7; the eye over 8d and 4th. Lower labials 8; the 5th largest. Scales smooth; disposed in 15 rows. Ven- trals 125 to 140; subcaudals 69 to 95; the latter seldom 70 per cent. of the former in number. Color above, grass-green, fading somewhat on the lower rows of scales. Below greenish yellow. On the throat and upper labials yellowish white. The green of the upper surface often changing in alcohol to blue. Distributed from Nova Scotia to Wyoming and southwest to New Mex- ico. Rare or not found in the Southern States. In Indiana it is probably generally, but not abundantly, distributed. Known localities: New Harmony (Sampson’s coll.) ; Brown county (collected by Chas. Jameson). This is a beautiful and inoffensive little creature. Its color indicates plainly both that it lives among green plants and that it is little able to: defend itself from the attacks of enemies. It must therefore depend on concealment for safety. It probably lives almost entirely in the grass, and rarely ascends trees and shrubbery, as does its relative, the Rough Green-snake. Holbrook says of it that ‘‘it isa very gentle animal, and can be handled with impunity; it seeks meadows of high grass, where crickets and grasshoppers abound, on which it feeds. It is found mostly on the ground, though at times I have seen it stretched on the branches- of low shrubs, as the dwarf willow.” DeKay (30, 40) says of it that it. is exceedingly quick and lively in its movements; that it is most abund- ant in marshes, and that it is reputed to fight’ furiously with the Striped snake. Prof. F. W. Putnam found in Massachusetts, on August 31, its- eggs under the bark of an old stump. They were just ready to hatch and one snake was already out. The eggs were an inch and a half long,. and the young a little over 5 inches. Genus PHYLLOPHILOPHIS, Garman. Phyllophilophis, Garman, 1883, 13, 40; Leptophis, Bell, 1826, 120, 328 ;- Baird and Girard, 1853, 6, 106. Body and tail very long and slender, and the body somewhat com- pressed.

Scales keeled, except those of the outer one or two rows; arranged in 17 rows. Anal plate divided. This genus differs from Cyclophis only in having the scales keeled. 87 Phyllophilophis eestivus, (Liun.)- Rough Green-snake.

Long and very slender; the tail whiplike, and constituting usually more than a third of the total length. Head separated from the body by a slender neck; narrow and high; swollen in the occipital region; the snout projecting considerably over the lower jaw. Eyes large. Scales keeled, except those of outer row and often some of the second row. Ven- trals 150 to 165; subeaudals 110 to 135. The latter seldom as many as 70 per cent. of the ventrals. Color grass-green above; below, greenish white. The green of the upper surface fades somewhat on the lower rows of scales. In alcohol the green changes to blue. The lower jaw and the upper labials are yellow- ish white. Maryland to Kansas, south to Florida and Mexico. Indiana localities : New Harmony (Sampson’s coll.) ; Vigo and Parke counties (Nor. School coll.) ; Dearborn county (A. W. Butler); Monroe county (Bollman) ; Cloverdale, Putnam county (Test). Hapsits.—This snake greatly resembles in general appearance and dis- position the Smooth Green-snake. It may be distinguished readily from the latter by its more slender form and by its keeled scales. It is equally as harmless as the other snake, and makes no attempt to bite when taken in the hands. It is given to climbing about on trees in search of the in- sects and larve that constitute its food. I have taken it while thus moving about on the branches of small trees. Of this species Holbrook says: ‘‘ Perfectly harmless and gentle, easily domesticated, and takes readily its food from the hand. I have seen it carried in the pocket or twisted around the arm or neck as a plaything, without ever evincing any disposition to mischief. In its wild state it lives among the branches. of trees and shrubs, shooting with great velocity from bough to bough, in pursuit of the insects which serve as its nourishment. Its green color, similar to the leaves among which it lives, afford it protection against those birds which prey upon it.” Prof. Cope (22, vi, 309) says of one that he kept in confinement that it manifested no disposition to climb over the ferns and plants among . which it lived, but that it lived mostly underground. It had a habit of projecting its head and two or three inches of its body above the ground and holding itself for hours rigidly in a single attitude. In this position it resembled very closely a sprout or shoot of some green succulent plant, and might readily be mistaken for such by small animals. 88 Genus STORERIA, B. & G- Storeria, Baird and Girard, 1853, 6, 135; Garman, 1883, 13, 29, in part.

The middle of the back with a paler, clay-col- ored, dusky-edged band, three or four scales wide. On each side of this wertebral band is a row of brown or black dots about the length of two scales apart. These sometimes extend themselves and meet across the dorsal stripe. Occasionally the dots, and sometimes the band itself, are wanting. In such cases the color above is uniform. Below the dots mentioned, other dots are occasionally seen. The color of the lower surface is whitish or yellowish in alcoholic specimens, but in life the color is often salmon or red. The ventrals with one or two dots of brown at their outer ends. Plates of the head brownish, with some minute dots. In highly colored specimens, there is a large brown spot just behind the head on each side; another spot on side of head and ‘across the corner of the mouth, and a small blotch under the eye. The Jength of grown examples is from twelve to fifteen inches. Distribution from Maine to the Mississippi Valley, and south to the Gulf and to Mexico. Probably occurring in every township in Indiana. Known localities are: Wheatland ( Ridgway); Lebanon (Nat. Mus.) ; IWew Harmony (Sampson’s coll.); Harrison county (specimens from Sse 89 Prof. Hallett); Monroe county (Bollman); Irvington; Terre Haute (Blatchley); Denver, Miami county, (Nor. Sch. coll.); Wabash county ( Ulrey ); Franklin county ( Butler ). The colors of this little serpent are such as harmonize well with its usual surroundings, the soil and dead grass, leaves, and slender, broken branches of trees. I have observed no evidences of its being aquatic, but some observers make such statement. DeKay reports that all that were seen by him were either in the water or in the vicinity of it. One taken by him was swimming across a bay of Long Island Sound. All that Holbrook has to say about it is that it frequents meadows and places where the grass is of luxuriant growth, and feeds on various insects, as crickets, grasshoppers, etc. They are ovoviviparous. A female, taken at Cumberland Gap, Tenn., and in midsummer, con- tained eleven eggs. The eggs were .37 inch by .25. Storeria occipitomaculata, (Storer). Storer’s Snake.

Averaging smaller in size than S. dekayi, which it resembles in propor- tions and in coloration. Snout short and blunt. Anteorbitals 2. Pos- torbitals 2. Nasals 2, with the nostril mostly in the anterior. No loral. Upper labials 5 to 6, growing larger posteriorly, the eye over third and fourth. Lower labials 6 or 7. Scales keeled; arranged in fifteen rows. Ventral scales 117 to 128; subcaudals 48 to 50. Color olive to reddish gray or chestnut brown. Along the back there is a paler stripe about three scales wide, and this is usually edged with dusky. Bordering the pale vertebral band and situated in the dusky border in each side is a row of brown dots. The vertebral band and the dots may all be faint or entirely absent. Often there is a yellowish stripe on the lowest row of scales. Head like the body, but mottled with brown. Behind the occipital plate is a spot of yellow, salmon in life, and a sim- ilar spot on each side just behind the corner of the mouth. The fourth and fifth labials with a small spot of similar color. Below, the color is yellowish ; in life salmon or brick-red. The ends of the ventrals mottled with dusky. Length of grown specimens about one foot. The territory occupied by this animal extends from Maine to Wiscon- sin and south to Georgia and Texas. In Indiana it is doubtless to be found everywhere. It has been collected at the following localities: New 90 Harmony (Sampson’s coll.) ; Montgomery county (A. W. Butler); Leb- anon, Boone county (S. F. Baird); Irvington, where it is less common than S. dekayi; Terre Haute (Blatchley). I know little about the habits of this snake. Smith (28, 698) states that they are somewhat nocturnal, and live chiefly under logs and stones. They are in all probability ovoviviparous. In the stomach of a specimen taken at Irvington I found a slug. Genus COLUBER, Linn. Coluber, Linnzeus, 1758, 64, ed. x, 216; Scotophis, Baird and Girard, 1853, 6,73; Hlaphis Garman, 1883, 13, 53.

Form elongated and rather slender. Tail tapering, and forming about one-fifth the total length, ending in a hard, straight spine. All the cephalic plates behind the prefrontals large. Postfrontals bent down ‘ok on the sides of the face. Vertical varying from narrower than long to wider than long; shorter than distance from its anterior border to snout. Upper labials 8 (rarely 7), eye over fourth and fifth; sixth and seventh largest. Lower labials 10 or 11, the sixth largest. Dorsal seales in 25 rows (rarely 25 or 27); the carination feeble, on the outer rows and on the tail obsolete. Ventral plates 200 to 234. Subcaudals 68 to 85. This is a distinctly spotted serpent. The ground color above varies from gray to brown and reddish, many of the scales having a broad edge of cream color. There is a dorsal series of broad blotches of a brown or chocolate color, and these are edged with black. These blotches, about 60 from head to tail, are from three to six scales long and extend down on the sides to about the sixth row of scales. They are separated on the back by two scales’ length. Alternating with these blotches is another series on each side, situated on the third to the seventh rows of scales. Below these is a third series, smaller and usually less distinct. They alternate with those of the second series, and lie opposite the dorsal. spots. Sometimes they lie on a level with the second series, but are smaller. The under surface is yellowish, with large squarish blotches of black. The head sometimes with a dark streak from the eye to the cor- ner of the mouth, and another downward from the eye. This snake may attain a total length of five feet, and even more. Its geographical range appears to be altogether northern, from Michigan to Minnesota and south to Southern Indiana. New Harmony (Sampson’s coll.) ; Wheatland (R. Ridgway); Hamilton County (Hay). This last mentioned specimen has 85 subcaudals. This snake appears to be the northern representative of C. guttatus, a species that is at home in the Southern States, but which also is found in Indiana. By some authors, as Mr. Samuel Garman, vulpinus is regarded as only a variety of guttatus. The latter may be recognized as a redder snake, with fewer blotches along the back (about 45, instead of 60), and with 27 rows of scales. The Fox-snake appears to be moderately common in some localities. It is often known as the ‘ Pilot-snake,” and is supposed to have some mys- terious connection with the rattlesnake. It is a wholly innocent snake, although,.as it seems, a little inclined to be pugnacious. Dr. Suckley (20, xii, pt. ii, 300) states that one of these snakes was brought to him alive at Ft. Snelling, Minn. When provoked it showed its irritation by vibrating the tip of its slender tail, which, when striking a crumpled leaf or any other small object, would produce a well-marked rattling noise, very similar to that made by the rattlesnake under the same circumstan- ces. Other observers make mention of the same habit. Mr. Robert Ridgway, of the Smithsonian Institution, writes me that, while hunting near Mt. Carmel, Il]., he came upon a Fox-snake over six 92 feet in length. It immediately showed a disposition to fight, and Mr. Ridgway says that it was the most viciously pugnacious snake that he had ever seen. An examination of the stomach showed that it had just swallowed a half-grown rabbit. Its disposition appears to be in strong contrast to that of C. obsoletus, which, so far as I have been able to learn, is very gentle. These snakes, being wholly harmless and subsisting on vermin of warious kinds, ought to receive the protection of the farmer. Coluber guttatus, Linn. Spotted Coluber. Coluber guttatus, Linnzeus, 1766, 64, ed. xii, i, 385; Holbrook, 1842, 54, iti, 65, pl. 14; Scotophis guttatus, Baird and Girard, 1853, 6, 78; Elaphis guttatus, Garman, 1883, 73, 55, pl. iv, fig. 1. Form elongated and somewhat compressed. Head narrow, tapering to the rounded snout. ‘Tail about one-sixth the total length. Cephalic plates not greatly different from those of C. vulpinus. The dorsal scales disposed in 27 rows; rather feebly keeled, those of some of the outer rows smooth. Ventral plates 214 to 236; subcaudals 63 to 79. The ground color is light red, fading in alcohol to brownish yellow. Along the back there is a series of about 40 blotches, or ‘‘ saddles” (Cope), of dark red, each dark bordered. These blotches are somewhat irregular and variable in form. They are from 4 to 6 scales in length. Below this dorsal series on each side is another series of spots, alternately larger and smaller. Of these, the larger alternate with the dorsal series. All these send down prolongations to the belly. The lower surface is checkered with black and yellow. Head red, with a band of dark red, edged with black, running across the face, through the eyes, and to the corners of the mouth, and on the sides of the neck; another narrower band in front of this, and a third from the back of the head to the neck. The size is about that of C. vulpinus. Distributed from Virginia to Illinois, and south to the Gulf of Mex- ico. It has been sent to the National Museum from Mt. Carmel, Illi- nois. ‘This Mt. Carmel specimen has only twenty-six rows of scales. Some Colubers in the collection of Mr. A. W. Butler, of Brookville, I refer to this species. Another specimen, undoubtedly C. guttatus, is said to have been taken in Putnam county, at Greencastle. It isa large specimen, and has the characteristic head-bands. The scales are wholly smooth. Of this serpent, Holbrook remarks that it is commonly observed about the roadsides early in the morning or at the dusk of evening; 93 unlike most snakes, concealing itself during the day. It is very gentle and familiar, frequenting the neighborhood of settlements, and at times entering houses. According to Catesby, it is a great robber of hen- roosts. If so, it must take the young fowls, and possibly the eggs. Coluber obsoletus, Say. Alleghany Black-snake.

Head rather broad and the snout blunt. Mouth large. Eye of medium size. Crown-shields 9; those behind the prefrontals large. Postfrontals bent down on the face. Rostral broad, and the snout projecting. Upper labials 8 (rarely 9) ; 6th and 7th largest. Lower labials 11; the 6th largest. Scales feebly keeled ; some of the exterior rows smooth; disposed in 27 rows (in some specimens, 25 rows*). Ventral plates 230 to 250; subcaudals 53 to 86. Color varying from gray brown to pitch-black, sometimes with a tinge of red. Often with numerous evident spots; sometimes the spots obso- lete, as in our form, the typical obsoletus. In this, the general color is a black with a bluish tinge, or a pitch-black, most pronounced on the pos- terior portion of the body. The anterior half may be lighter, and show evidences of blotches. The whole of this part may have a decided tinge of red, this being due to the color of the skin between the scales; yet the red may run up on the bases of the scales. Occasionally the spots of the upper surface are of a decided red. The dorsal blotches extend down on the sides to about the 7th row of scales, counting from the lowest. They are about 6 scales long, and are separated by the length of 2 scales. Alternating with these is another series which extend frome the 5d to the 7th rows of scales. These spots are all feebly indicated by the sulphur yellow of the skin between the scales; and often the color is almost uniform black. There are some scales with yellow or white edges. Lower jaw and throat white. The belly is of a slate-color or black on the hinder half; anteriorly the black is mottled with yellow- ish, which color becomes more and more abundant, until the throat and chin are entirely yellowish. Small, or even half-grown, individuals may have a ground color of ash-gray and numerous dark blotches. *A specimen from Brookville, Indiana, which resembles in other respects C. obsoletua,- has 29 rows of scales, 94 Coluber obsoletus confinis is common in the southern portion of the United States. It has the scales in twenty-five, occasionally twenty- seven, rows. ‘The ground color is ash gray, and there are about forty- four elongated dorsal blotches of dark chocolate brown. Below these blotches are two other series of elongated spots of a similar color. The latter spots run together to form on each side, especially arteriorly, a longitudinal stripe. Ventral plates about 240. A specimen of Coluber, fourteen inches long, sent me from Terre Haute by Prof. Blatchley, agrees in almost every respect with Baird and Girard’s description of Scotophis confinis. It has, however, two temporal plates, instead of one, as stated by Prof. Cope. It is undoubtedly the same form as two large specimens before me, one from Georgia, the other from Mississippi. The latter belong to Coluber spiloides. When the small specimen is compared with other half-grown and adult specimens of C. obsoletus, they appear to form an unbroken series from the very spotted young up to the adults of uniform black. I conclude that C. spilcides is not more than a variety of C. obsoletus, and C. confinis is probably an individual variation with respect to its temporals. Coluber obsoletus obsoletus ranges from southeast New York and the east- ern base of the Alleghany Mountains to the plains, and south to North Carolina and Texas. It probably occurs in all portions of our own State. It has been taken in the following localities: Wheatland (Ridgway); Franklin county, where it is common (Hughes and But- ler); Monroe county (Ind. Univ. coll.); Jackson county (St. Nor. Sch. coll.); Terre Haute (St. Nor. Sch. coll. and Prof. Blatchley) ; Irvington (W. P. Hay). Three of the specimens examined, one taken at Irvington, another taken in Jackson county, and a third from Terre Haute, had only twenty-five rows of scales. So far as Iam aware, this is entirely a forest-inhabiting species. Our indistinctly spotted and almost jet black form is not distinguished by most people from the Black-racer, although it is a very different snake. The latter is a sienderer snake and has very smooth scales in only sey- enteen rows. Coluber obsoletus spends its time hiding about hollow logs and in holes about standing trees. It often ascends trees in search of birds and their young. Mr. Amos W. Butler, of Brookville, says that they are the most destructive to birds of all our snakes. Besides birds, they no doubt prey on mice, rats, rabbits and other small animals. The dispo- sition of this serpent is gentle, and it makes little resistance when sur- prised and seized by head and tail. It will open its mouth in an at- tempt to bite, but struggles little. Under such circumstances a Racer would make a lively disturbance. One put into a box with a mouse sould strike at the latter whenever it showed too much familiarity, but 95 it was not harmed. In the stomach of one individual I found a number of young mice; in another were two old and six young mice. This species probably reaches a greater size than any other snake that we have. Dr. Robert Ridgway tells me that he killed one at Mt. Car- mel, Ill. which he estimated to be over nine feet long. It made no resistance when attacked and was as easily killed as an ordinary snake two or three feet long. This species has the habit, common with many snakes, of vibrating its tail so as to make a rattling or whirring sound. This probably serves to warn the larger animals of its presence, so that they may avoid it. Dr. G. B. Goode includes this snake among those which are said to ‘‘swallow” their young; that is, when danger threatens they open their mouths, in order to allow the young to pass down the mother’s throat for safety. More observations need to be made on this subject. I have been able to find in print no observations on the breeding habits of this snake. When and where are the eggs laid? How many of these are there? How soon do they hatch? These are a few of the things that many a farmer’s boy might be able to find out for us. Two indi- viduals were taken at Fall Creek, Marion County, while in sexual union. This was on June 19. The male was 5 ft. 3 in. long; the female was 6 ft. 3in. The female contained sixteen eggs. They have a thick cov- ering, and must be Jaid before hatching. Prof. Blatchley writes (94, ’91, 31) that he kept one, 5 ft. 7 in. long, for sometime in confinement. It would, on being disturbed, vibrate its tail in such a way as to make a rattling sound. When the room was entered at night with a lamp the snake would hiss with a loud, gurgling noise. A large Horned Owl, kept in the same room, was attacked by the snake, tightly enveloped in its -coils and so badly crushed that it soon died. Maximilian (103, xxxii) has confirmed the popular notion that the snake will eat fowls’ eggs. One entered his room, climbed to a vessel of eggs, and swallowed a number of them. After the eggs had passed down the throat the shells were crushed by a powerful constriction of the walls -of the stomach. Genus NATRIX, Laurenti.
