RHOADS... MAMMALS OF PENNSYLVANIA AND NEW JERSEY. BY SAMUEL N. RHOADS. INTRODUCTION. Jos, the ancient divine and naturalist, asks, “Who teacheth us more than the beasts of the earth or maketh us wiser than the fowls of heaven?” Owing to the difficulty of making acquaintance with those “ beasts of the earth” which we call A/amma/s, because of their nocturnal, subterranean or aquatic habits, the study of mammalogy has never been as popular as that of the “fowls of heaven.” It is, however, nq less an interesting and profitable study and even yet furnishes the investigator, in spite of the great activity of the past decade in that branch, a far richer field for original zodlogical study than does ornithology. To man, himself a mammal, the importance of this study, especially as regards his physical, mental and spiritual relation- ships to the beasts of the earth, cannot, perhaps, be overestimated. One of the most noticeable developments in biological research at the present day is along the line of geographic distribution. It has resulted in the solution of many vexed problems which the last century biologist vainly pondered. In the prosecution of this line of research much is discovered of an incidental character relating to the life-history of created things which has hitherto been hidden away. ‘These are some of the facts which induced me, eleven years ago, to begin the work which forms the subject of this paper. In these studies I have been aided to a limited extent by the all- too-meagre and often misleading faunal publications of previous authors. More substantial and valuable aid has been received by means of voluminous correspondence and personal interviews with naturalists, trappers, hunters, old pioneers and frontiersmen living in the regions named. The main source of information, however, has been personal field experience in nearly every county in the two states. The collections of Pennsylvania and New Jersey mammals, resulting from this work, and numbering about 2,000 speci- mens, have recently been acquired by the Academy of Natural Sciences of Philadelphia. For the use of the unrivalled literary and museum facilities of this institution and the continued courtesy of its officers I am glad to have this opportunity to express my thankfulness. 2 MAMMALS OF PENNSYLVANIA AND NEW JERSEY. The scope of the work now completed, may be thus defined. It treats of both living and extinct, recent and fossil, land and sea mammals found in Pennsylvania and New Jersey in the feral state. It includes not only those indigenous or native to the region but also those which have been intro- duced there either from native or foreign regions, whether by man’s direct importation or by voluntary migration due to faunal and floral changes wrought by the deforesting and settling of the country since the beginnings of colonial history. After giving each native species and sub-species its most approved popular and scientific nomenclature with double literary references for the student, the “ Zype locality,” “ Faunal distribution,” “ Distribution in Pennsylvania and New Fersey,” “ Records” in the two states, “ Habits and economic status,” “ Historic references,” “ Description of species,” and enumeration of “Specimen sexamined,” are also given more or less fully as each requires. The fossil species are more briefly considered and in a separate division. Reference has already been made to the importance of the study of faunal distribution. A map of the two states, giving the limitations of the Lower Canadian, Transition and Upper Austral life-zones represented in their limits, has been prepared and the distribution of each species given in the text is stated in terms of these. The results of my observations enable me to define these with greater exactness than was heretofore possible, and to alter, in some degree, the complexion of the zodgeographic map heretofore used as a standard by students. As near as possible this is made to conform to our knowledge of primeval conditions, a standard now difficult to reproduce, owing to the vital biological changes which have resulted solely from the deforestation of our country. Fire, axe, flood, summer sun and winter frost have made the famous hunting grounds and natural game preserves of the Pennsylvania Alleghanies a wilderness indeed. Where once the Canada Lynx, Wolverene, Fisher, Marten, Canada Deer-Mouse, Woodland Jumping Mouse, Northern Hare, and Marsh Shrew found a congenial home, the average mid-summer temperature may now be roughly said to have risen 20 degrees, drought and flood quickly succeed each other, winds become tem- pests and winter takes on an Arctic severity. Instead of white pines and hemlocks we have scrub oaks and briars; instead of fern beds, sphagnum and moist shade we find bare rocks, glaring sun, and withered vegetation. The grinning opossum sneaks up the south slope as the last snowshoe hare hops down the northern one, and the lowland cotton-tail forthwith jumps her ancestral claim. While the rifle and the trap remained their greatest enemies, the beasts of the earth and the fowls of heaven had an even chance, but the era of axe and fire and commercialism has doomed them, unless the era of forestry soon rescues them from extinction. To explain more fully the use and intent of the accompanying map of the MAMMALS OF PENNSYLVANIA AND NEW JERSEY. 3 faune or life-zones of Pennsylvania and New Jersey, I will quote G.S. Miller, Jr.’s, lucid remarks thereon, given in his “Preliminary List of the Mammals of New York,” “The importance of an acquaintance with the life-areas of a region, as a key to the geographic distribution of the animals and plants, is hardly to be over-estimated. Such knowledge furnishes ready and exact means of defining the ranges of species without the tedious enumeration of isolated localities, and offers moreover an explanation of the principal factor governing those associations of species that constitute local faunze and flor. Briefly defined, a 4/e-zone is a trans-continental area bounded by certain isothermal (average temperature) lines, and characterized by relative uniformity of fauna and flora. Together with the isotherms a life- zone normally extends in an approximately east and west direction, but both are subject to endless deviations. Elevations in the surface of the earth cause the life-zones to bend to the southward, often many hundreds of miles beyond their sea level position. Furthermore, a life-zone is not necessarily ‘continuous. It often happens that isolated hills or mountains reach a suffi- cient height to have about their summits the climatic conditions char- acteristic of a more northerly zone than at their bases. Effects similar to those of elevation are produced by: isolated swamps and cold rock slides.” Illustrative of these remarks we find on looking at the map of Pennsylvania that the higher Alleghanian chain bearing the Canadian fauna on its crest, ‘cuts the eastern and western extension of the transition zone in half, while the valley of the upper eastern branch of the Susquehanna brings about a reversal of these conditions by bisecting the Canadian zone with an offset' of the Transition. In Fayette and Somerset Counties a most striking alterna- tion of Austral, Canadian and Transition zones occurs as we travel along the Maryland line, due to the intrusive parallel range of the Alleghany ridge, Laurel ridge, and Chestnut ridge, with their intervening valleys. In the upper Austral zone of south New Jersey the “ boreal”’ or transition islands of cool, dense-shaded cedar swamp and bog are a striking illustration of local conditions, and a like instance is the typical Canadian fauna of certain tamarack and fir swamps set in the midst of otherwise doubtfully Canadian regions in the northern part of both states. In North America seven life zones are represented. These are (begin- ning at the north) the Arctic, Hudsonian, Canadian, Transition, Upper Austral, Lower Austral and Tropical. The temperatures limiting three life areas farmed in our limits are tabulated as follows, by Merriam :—These are based on the two laws “(1) Zhe northward distribution of animals and plants is determined by the total quantity of heat—the sum of the effective tem- peratures. (2) The southward distribution of Boreal, Transition zone and Upper Austral species is determined by the mean temperature of the hottesr part of the year.” Southern limit of the Canadian zone is defined by the iso- 4 MAMMALS OF PENNSYLVANIA AND NEW JERSEY. therm showing a normal mean temperature of six hottest consecutive weeks of 64.4 degrees; of the Transition zone, ditto, 71.6 degrees; of the Upper Austral, 78.8 degrees. The northern limits of the Transition and’ Upper Austral zones are defined by the sum of normal, mean daily temperatures for the year above 43 degrees, which is 10,000 degrees for the Transition and 11,500 for the Upper Austral. , In the case of rare or exterminated species a series of records of their historic or more recent occurrence in the various parts of the two states is given by counties. These have been condensed and summarized from an extended correspondence with observers, historians, scientific students, trap- pers, furriers and sportsmen, some of whom, very old men, have since died, and their valuable knowledge of pioneer conditions in our limits would have largely gone with them had it not been thus recorded. The habits and economic relations of most of the species are touched upon ; those of greater interest, because so little known, as popularly mis- judged or now exterminated, are more fully treated. In this connection it may be stated that there is only one species of a#ive mouse in Pennsylvania and New Jersey, namely, the mole mouse, underground’ meadow mouse, or pine vole, AZ. pinetorum, whose food habits may be said to be so noxious as to make its extermination a desideratum. Moles, shrews and common meadow mice are greatly misunderstood even by those'who profess to study them from an economic point of view. The status of the rapacious carnivora —skunks, weasels, minks, coons, bears, wild cats, foxes, etc—which still form a large part of the living population of our forests, deserves as thorough study as has been recently given by the United States Department of Agri- culture to rapacious birds. From the researches of Dr. Warren in Penn- sylvania along this line we may predict that the popular verdict on these vagabonds will in many cases be found faulty. The commercial importance of many so-called “injurious” mammals, which yield either food or furs. to man, is far greater than many realize. For instance the trade, and conse- quent profits, arising from the trapping of muskrats in the Delaware Valley alone amounts to many thousands of dollars annually, and offsets a hundred fold their destruction of dikes, dams, forage crops or grain. The bodies of these muskrats are rarely wasted, being so prized in Cumberland Go., New Jersey, as to have a standard market value of five to eight cents each. The Cetacea, or Whales and Dolphins, generally ignored in mammal study ‘because of the confusion so long existing as to their character, identity and habits, have been given special attention, forming as they do, such a numerous representation in the waters of New Jersey. No less than eighteen species of these leviathans, ranging in length from ‘5 to 80 feet, wander to or now exist off our shores, some of the “largest entering tidewater as far inland as Trenton. Nine additional extinct whales roamed MAMMALS OF PENNSYLVANIA AND NEW JERSEY. 5 in the once tropical waters which covered southern New Jersey during the Miocene period. Whaling formed, at one time, an industrial feature of the New Jersey coasts, but has long been abandoned. Species now extinct in our limits, which formed an important role in the domestic economy of-our great-grandfathers are the Bison, Wapiti or Elk, Beaver, Cougar or “ Panther’? and Wolf. The bison, only a straggler east of the Susquehanna, and never abundant in Pennsylvania in the white man’s memory, was last killed in Union Co., Pa., about 1800. The last Pennsylva- nia Elk or Wapiti was killed in Elk Co., in 1867 by Cornplanter Indians from the Cattaraugus Reservation. ‘This animal was formerly abundant over the greater part of the state in the higher grounds, and was used as food. Though the native Beaver has been practically exterminated in our limits since 1875 there is a colony of wild beavers in Monroe Co., Pa., and several others in Sussex Co., N. J., all of which, there seems little doubt, are de- scendants of escaped imported beavers from Rutherford’s game preserve near Allamuchy, Warren Co., N. J. They are increasing, and laws are being enacted for their preservation. The last Pennsylvania Cougars or “panthers” of which I have absolute proof of capture were a male anda female, killed in Clinton Co. by George Hastings in 1871. A Centre Co. specimen is recorded in the bounty records of that county for 1886, but I have been unable to verify its reliability. Others have been reported killed as late as 1893, but are of doubtful standing. Native Wolves apparently existed in Pennsylvania as late as 1890. All wolves killed since then seem to have been importations liberated by bounty thieves or escaped from traveling shows. Wolfish dogs are a perennial source of local wolf stories. The Canada Lynx, never numerous here, probably lingers in solitary cases in the northern wilds of Pennsylvania. Bears, Wild Cats and Foxes are in- creasing in our extensive deforested districts. The list of fossil mammalia found in Pennsylvania and New Jersey greatly exceeds that of the rest of the United States east of the Mississippi river. This is due to the discovery of the numerous fossil-bearing limestone caves and fissures in the Delaware valley, and to the researches of Leidy, Marsh and Cope among these and in the marl beds of New Jersey. Of mammals strictly non-recent, our list of fossil mammalia embraces the following : Edentates or giant sloths, 5 species ; Sirenians or aquatic manatees and dugongs, 2 ; Cetaceans or whales and dolphins, 9 ; Ungulates, such as the elephant, rhinoceros, tapir, horse, peccaries, deer and wild oxen, 16; Rodents, such as pikas, giant beavers, rats and squirrels, 10; Pinnipeds, such as walrus and sea leopard, 3 ; Carnivores, such as sabre-tooth cats, cave bears, skunks and otters, 15, and Insectivores, such as shrews, 1. In all there are 61 species of strictly fossil non-existent species recorded from our limits, the greater part of which were originally discovered: in Pennsylvania 6 MAMMALS OF PENNSYLVANIA AND NEW JERSEY. and New Jersey. If we add to these the go species found associated in the fossil state with the others, but which are identical with existing species, we have a list of 91 species of fossil mammalia recorded from Pennsylvania and New Jersey. Comparing this with the list of species native to and recently existing in the two states and which numbers 71 species and 25 subspecies. or geographic races, we have the rather extraordinary result of a known extinct mammalian fauna of two eastern states exceeding their existing mammal fauna. This is the more noteworthy in that nearly all of the terrestrial extinct species have been found in pleistocene, drift or terrace periods, which are supposed to so closely antedate' the present age. In contrast with this I may mention that the known extinct mammalian fauna of New York, as given recently by Miller, only numbers 5 species. Another interesting fact, shown by our list, is the former existence in Pennsylvania. and New Jersey of living species now confined to the Arctic and sub-Arctic faune of Canada. Of these I may mention the caribou, musk ox, moose, wolverene and walrus. Of the southern or tropical fossil genera, once very abundant in the Delaware Valley, none of the characteristic Sirenians. giant sloths, shark-toothed dolphins, tapirs, peccaries, iastodons, rhinoceros. or sabre-tooth cats now exist anywhere in the earth. These are two of the many interesting proofs of the Arctic source of Postpliocene extinction. It will naturally be asked, “ What previous publications have been made regarding the mammalogy of Pennsylvania and New Jersey?” The most pretentious, and in fact the only work relating to the entire state of Pennsylvania is found in much scattered form in Dr. B. H. War- ren’s part of the book entitled “ Diseases and Enemies of Poultry,’ pub- lished in 18y7 by the Pennsylvania Department of Agriculture. In this. many mammals are treated at length from the economic standpoint, and incidentally a large amount of valuable information, secured from residents of the state, has been recorded regarding other species. As a book of general reference, however, or as a list of species of Pennsylvania mammals, the book makes no pretensions. A few local Pennsylvania county lists, almost worse than useless because misleading, “have been inserted in older histories.’” The same may be said of the local county literature relating to New Jersey. Dr. C.C. Abbot’s list of mammals, published in the appendix to the “ Geology of New Jersey ” in 1868, is the only one relating to the recent mammalia. of that state worthy of mention. It enumerates forty-seven species, about one-half of the number now known. Prof. E. D. Cope’s list of extinct New Jersey mammals in the same book includes only twenty species, nearly all of which were based on specimens from the marl beds. This number, in the light of subsequent discoveries, is nearly doubled. Since the studies just summarized were begun, twelve existing species, not previously known to occur in Pennsylvania and New Jersey, have been there MAMMALS OF PENNSYLVANIA AND NEW JERSEY. 7 discovered. Of these, four, a small weasel, a native cave rat larger than the Norway rat, a red-backed wood mouse or vole, and a lemming-vole, the former two from Pennsylvania, the latter from New Jersey, have been de- scribed as new to science. The specific synonymy used in the present paper is strictly confined to a double literary reference ; first, to the earliest use of the name accompanied by an original description of the species ; secondly, to the first use of the bi- nomial or trinomial which I have considered applicable to it in the light of present knowledge. The unpublished quotations from correspondents are suc- ceeded by their last names only, and a list of these with their addresses given in full at the end of the paper. Published quotations are accompanied by references. No bibliographic list has been prepared owing to the very lim- ited number of references of importance relating to our mammals except those published in Philadelphia Journals of the Academy of Natural Sciences, the American Philosophical Society, and in the American Naturalist. The measurements given are in millimeters, their equivalents in inches being given in brackets following. It may be explained that the “ Zype Locality” is the place or region where the specimen or-specimens forming the original description of the species, binomially named, was a native. The excellence of the illustrations is largely due to the skillful reproductive photography of Mr. H. Parker Rolfe, of Philadelphia. Space fails me to here express more particularly the kind assistance rendered by the many correspondents whose names are given in the appendix. They have my grateful thanks. Audubon, N.

In extremity a cannibal and eater of carrion. Owing its urban existence to non-resistance, fecundity, omnivorous diet and a prehensile tail. Producing sometimes as many as sixteen young, which at birth are three-fuurths inch long, naked and with rudimentary hind limbs; each securely attached toa teat within the abdominal pouch, from which they emerge when of the size of small rats and cling by tail and feet to the body of the parent. Stated to have three litters in a year. Its habit of eating wild birds, their eggs and young, and its fondness for poultry offset in some degree its usefulness as a 10 MAMMALS OF PENNSYLVANIA AND NEW JERSEY. ‘scavenger, an eater of injurious animals, a producer of furs and food for man.

Habits, etc —Once abundant in the north Atlantic and nearing extinction, but now increasing in numbers.—Holder, 1883. The baleen or sieve-like bristles within the mouth separate the minute crustaceans and pteropods which swarm in immense shoals where it feeds. To secure these it takes a mouthful of water and in the act of closing it and ejecting the water the baleen project from the palate automatically and close together in front of the ejected water, straining out and retaining any food which it contains. True says (Cat. Aquat. Mam. U.S. N. M., Ind. Fish Exhib., 1884, p. 13) that this species “is believed to have been the object of very considerable fishery in early colonial times, but has disappeared entirely for many years.” Records in Pa. and N. J.: “They were formerly abundant about the mouth of the Delaware river. A letter of William Penn dated 1683 states that eleven were taken that year about the Capes. Five specimens are stated to have been seen in tie Dela- ware river since that time, and two of great size are recorded to have been seen on the coast of Maryland.”—Cope, Proc. A. N. Sci., Phila., 1865, p. 168. The type specimen of Cope’s Balaena cisarctica, now considered a synonym of B. g/acialis, was taken in 1862 in the river opposite Philadelphia.
