The most superficial examination of the natural productions of Washington Territory cannot fail to show that it possesses a remarkable variety of botanical and zoological regions, each distinguished by more or less peculiar forms of life. A concise and systematic account of them, as far as they fell under my observation, seems necessary to complete the scattered notes on the distribution of species which I have already given. Reversing the usual order, I com mence with the most elevated region, which was one of the first I visited. At an elevation of 5, 000 feet above the ocean we found the vegetation and animals subalpine in character, but still with a preponderance of those belonging to the lower country. On the hills, there but partially covered with forests, we found, during our visit in the first week of August, a profusion of berries of several kinds, which the Indians were engaged in collecting. Among them was a huckleberry not before seen, (V. myrtilloides? Michx.,) with fruit nearly as large and as finely flavored as a grape. Two kinds of pine, (P. monticola. Dougl.,) resembling the white pine, and (P. ponderosa, Dougl.,) with a magnificent species of mountain spruce, (A. nobilis, Dougl.,) were the characteristic trees, replacing, to some extent, those of the lower regions. Blue, purple, red, yellow, and white flowers, in rich profusion, ornamented the surface; and the whole region looked more like a garden than a wild mountain summit, covered for nearly half the year with snow. On the morning of August 9, a rain having extinguished the burning of the forests below us, and cleared away the smoke which had for several days obscured the view, there was revealed to us a scene probably unsurpassed in magnificence by any in America. Five snowy peaks surrounded us, rising many thousand feet above our camp; and we found that we were still far below the limits of perpetual snow. From a distant view I supposed that dwarf vege tation continued on these peaks for a thousand feet higher, forming the truly alpine region, and I much regretted that time did not permit me to explore this. Months might be well spent in collecting in this most interesting region, even above the limits of the forest growth. It is well known to have even a group of large animals peculiar to it — such as the mountain sheep and goat, white grouse, and probably others. A dwarf glaucous juniper, (J. COMMUNIS,) with large berries, spreading like a carpet on the summit of the highest point I ascended, was the most characteristic subalpine plant, and seemed to be limited to that region, as none occurred lower down. This point was, by the barometer, nearly 5,103 feet above the sea. The vegetation of August, at this height, corresponded to that of May at Vancouver, many of the same plants occurring in flower, though of a more stunted growth. But spring, summer, 14 BOTANY OF THE ROUTE. and autumn are so crowded into the space of three to five short months that even the subalpino region may be said to have but two seasons — first, that of vegetation, and secondly, winter, continuing for the rest of the year, while the ground is covered with snow. Though the days were very warm during our stay there, ice formed at night one-third of an inch thick at our camp : and we had a violent and cold hailstorm, which for a short time buried the flowers, thus in an hour changing summer into winter. The precise limits of the seasons cannot be definitely fixed, and probably vary much in different years and on the different exposures of the mountains. About the 12th of the following October snow fell in the Nachess Pass during Lieutenant Hodge' s journey across it, its elevation being nearly the same, 4, 890 feet above the sea. Snow is known to fall at this height in every month between September and May, but it does not lie constantly for so long a time, and vegetation probably goes on during both those months, and even for a month or two longer. But the local differences are very great and must amount to a month or more, according to the exposures of surface to sun and rain even at the same elevation. There is no dry season at this height, as clouds are almost constantly hovering about the peaks, and rain can be seen even from the valleys below, falling at all seasons, especially on the more westward parts of the range. I found animals more abundant in this cool elevated region than below. The large herbivo rous quadrupeds had sought the fresh spring-like herbage, and were probably followed by many beasts of prey. Ducks, geese, and cranes abounded, with the interesting little phalarope, seeking these cool regions to raise their young; but in our hasty journey across I could merely glance at the multitude of new beings which surrounded me. The moist hollows between the mountains were densely covered with rank grass, promising rich pasturage for the herds which, when the country becomes more settled, will doubtless be driven there during the summer, when the plains eastward are parched by drought. In healthi ness and beauty of scenery these mountains cannot be excelled. On the llth of August we commenced to descend the eastern slopes of the Cascade range near the base of Mount Adams, and at once found ourselves in quite a different natural region from any before seen. Although forests continue as on the western slopes, they are composed of entirely distinct species of trees, and have a very different appearance. Instead of spruces, one pine almost exclusively prevails, (P. PONDEEOSA, called " Yellow Pine, ' 7 ) growing usually over a hundred feet high, with a straight clear trunk three to five feet thick, branching at the height of about forty feet. Its bark is thick, reddish, and deeply furrowed, like that of the chestnut. The wood is said to be unusually heavy and useful for many purposes, besides being excellent fuel. A few of the smaller "White Pine" and stunted larches are mixed with this on the higher parts of the slope, and descending below, about the elevation of 3, 500 feet, the oak began to reappear. There is so little underbrush in these forests that a wagon may be drawn through them without difficulty, forming a striking contrast to the dense thickets of the western slopes, to be here after described. The level terraces, covered everywhere with good grass and shaded by fine symmetrical trees of great size, through whose open light foliage the sun's rays penetrate with agreeable mildness, give to these forests the appearance of an immense ornamental park. Almost the only shrub is a Ceanothus, (0. VELUTINUS, Dougl.t) with beautiful shining foliage and a strong aromatic odor something like cinnamon, growing in scattered thickets. This beautiful forest continued for about twelve miles eastward from Mount Adams. It BOTANY OF THE ROUTE. 15 occupies a zone along the eastern side of the mountains between the heights of 2,500 and 5,000 feet at the Columbia river, and becoming lower as we go northward, until at fort Colville and on the Okanagan river, at latitude 49°, it extends quite down to the level of the rivers, occupying all the surface except some small prairies in the valleys. At the mountain gaps of the Columbia and Yakima rivers trees also extend further down along the streams, but in small numbers. The well marked and usually abrupt lower limit of these forests evidently corresponds to the degree of moisture derived either from the rains of the mountain summits, or from the rivers. The moist winds from the ocean, intercepted by the highest ridges, pass through the two gaps above mentioned, and to a small extent favor the growth of trees lower down. Doubtless the cessation of fires on the dry plains will be followed by a further increase of forests in such places. North of latitude 48°, the country being generally hilly, is better supplied with rains; and on the northern slopes of the hills I observed dense forests, while frequently their soutJiern exposures were bare, showing the direction of the prevailing winds and consequent moisture. This fact was also noticed by others among the western spurs of the Rocky mountains. The same effect is well marked southward on Cape Mendocino, in California; while thirty miles south of San Francisco trees almost entirely of a distinct and southern group grow chiefly on the southern slopes, indicating a corresponding difference in the direction of the moist winds. The dry season was already far progressed, and I found, therefore, but few plants in a con dition for preservation, though those collected happened to be of peculiar interest. — (See Phce- lipoea comosa, Erigeron Douglasii, Poeonia Brownii, Spraguea umbellata, Acer glabrum, &c.) The entire vegetation seems to belong to the Rocky mountain group much more than that of the western slopes, although several of the plants are, as far as- known, peculiar to this range and the Sierra Nevada. A corresponding group of animals also first appeared there, such as the coyote, badger, and Say's striped squirrel; but large game continued very scarce, and the season was unfavorable for birds, which seemed to have almost all deserted these forests during August. To complete their description, I extract from my journal the notes on these forests as they appeared further north, and at later seasons. On September 13 I rode from the camp on the Yakima about fifteen miles up its valley, and found the forest commencing about six miles up, at an elevation of about 2, 200 feet, as abruptly as where we left it before, with exactly similar vegetation and the same dreary absence of animal life. On the 20th the expedition crossed the ridge separating the waters of the Yakima and Pisquouse rivers. There, 5, 750 feet above the sea, we found a scattered belt of forest, in which the larch, (L. OCCIDENTALS, Nuttal) appeared, of great size, and about equal in abund ance with the pines. This magnificent tree sometimes excels the latter in size, and its feathery foliage, just beginning to fade yellow, gave it a beautiful appearance in contrast to the deep green forest around it. With these were a few scattered spruces of several species, which I could not well determine, finding no cones. From the summit of this ridge we had a panoramic view of a vast extent of country on all sides of us. Towards the west the numberless irregular peaks of the Cascade range looked like the confused waves of a rough sea. Below their highest snow-capped peaks the belt of forest could be plainly seen extending down on spurs to the Ot)lumbia, but crossing it only at a far distant point near the northern boundary of the " Great Plain," which extended eastward 16 BOTANY OF THE ROUTE. as far as we could see. But large portions of the ridges west of the river were also bare of trees to an apparent height of about 3, 000 feet. Further north we met with none but scattered patches of forest, until reaching the high ridges bounding the valleys of the Methow and Okan- agan rivers, where, as well as along their banks, trees are grouped in beautiful groves, forming a sufficient supply for the population which must in time inhabit these picturesque valleys. I have already noticed the prevalence of the forests near the 49th degree along the Columbia, and most of the country thence south to latitude 38° 30' is occupied by them. From Fort Colville, southward, to the Spokane river, we found a pleasing country of mixed forests and prairies, with a fertile soil, which is evidently in part due to the intermingling of spurs of the Cascade mountains with those of the Bitter Root range, which appear towards the east well covered with forests on their higher parts. They intercept and precipitate over these northern tracts sufficient moisture to make them highly fertile. The lowest points on the Great Plain where trees are found in any abundance are about 2,000 feet above the sea. This most elevated division of the great forest regions of the Territory, covering only the mountain slopes and summits, botanically and zoologically constitute a south ward extension of the more northern flora and fauna following the mountain ridges, and thus irregularly interlocking with the third great region of plains. Towards the east and south a dryer climate is found to diminish the extent of forests, until gradually rising higher and higher towards the line of perpetual snow, at length they almost disappear on some of the eastern slopes of the Rocky mountains and on the ranges of southern Oregon and Utah. GEEAT PLAIN OF THE COLUMBIA. Although the great forests west of the Cascade range might most naturally follow in the description of regions after those just mentioned, being allied to them in products and in rela tion to climatic agencies, I prefer to give here the brief and incomplete observations which I was able to make during our journey over the Great Plain, occupying the central portion of the Territory. This region, characterized by an entire absence of trees, occupies an intermediate place in elevation between the mountain forests and the lowlands. Though its name gives the impres sion of a surface uniformly level, it has (as remarked in my preliminary report) its mountains and valleys, which cannot be separated by any peculiarities of natural products, and must, in a technical sense, be considered as a part of the "plains" region. Thus, on the divide between the Yakima and Pisquouse, I noticed that the forests did not appear until near its summit, at nearly 5,000 feet elevation. East of Mount Adams the greatest height of the woodless regions is 3,000 feet, at the Spokane river about 2,600 feet, and the lowest point near the centre of the Columbia plain, at Walla- Walla, is 409 feet above Vancouver. Though the canon of the Columbia is cut down through the elevated plain to the level of 119 feet at the Dalles, the general surface around is much higher, and at the lower points there is little doubt that trees would grow freely if protected from fires, being encouraged by the constant supply of moisture carried through the gap of the mountain by the prevailing strong west winds. I may therefore assume an average elevation of from 500 to 2,500 feet for the dry region of the central portion of the Territory, where trees will not grow without artificial irrigation. This Great Plain of the Columbia is bounded on the north by an irregular line running between the parallels of 48° and 49°, north of which it is presumed that but few branches of it extend, BOTANY OF THE ROUTE. 17 the country becoming very mountainous, and therefore well wooded. Southward it is continuous with the central plains of Oregon, through them with those of Utah, and through the South Pass with the vast plains extending eastward to the Mississippi river. In order to show the peculiarities in the vegetation of the plain region, I have included the plants collected there in a separate list. Though made at an unfavorable season, and few in number, they show a marked dissimilarity from those obtained west of the mountains, yet many of the latter belonging to the prairies west of the mountains are also known to be found on the plains of the central districts. One peculiar group of shrubs represents in this region the forest trees, and are characteristic of all the plain regions between the eastern base of the Rocky mountains and the Pacific. (PursJiia tridentata, Artemisia tridentata, Linosyris albicaulis, L. viscidiflora, Sarcobatus ver- micularis.) As the most characteristic animals, I refer to the badger, coyote, or barking wolf, cock of the plains, or sage fowl ; sharp-tailed grouse, or prairie chicken, and other smaller kinds, mentioned more particularly elsewhere. The antelope, buffalo, prairie dog, and some others found in other parts of the plains, doubtless are sometimes to be met with in this Territory, though we neither saw them nor heard of them as being common. The various divisions of the plains due to differences of elevations, soil, and moisture, have each their peculiarities, which would require a long description, had my opportunities been sufficient to make it complete. A short notice of the most striking may not be without interest here. The high ridges forming spurs of the Cascade range, extending \vith a gradual slope from the pine forests down to the Columbia on each side the Yakima valley, between its branches, are too dry to serve as anything but a grazing region. Some portions near their summits are also very rocky and barren, but these are comparatively small. The greatest obstacle to cultivation is the absence of means of irrigation, but there can be little doubt of the success of winter grains on many parts of these ridges. The Spokane plain, between that river and the Snake, west of longitude 118°, resembles, in soil and elevation, the lowest part of these ridges, being from 500 to 2,500 feet in elevation. But being a great plateau, it has the advantage of retaining moisture, and in many parts are tracts sufficiently irrigated naturally for general cultivation. Alkaline lakes and marshes, and some very rocky portions, are all that cannot be made use of, but these seem to occupy comparatively a small extent of it. On all the branches of the northern Columbia crossed by us we found valleys of various extent, which form the best portion of the plain region. Terraces varying in height from five to two hundred feet above the water border these valleys, and present various soils, from the very dry gravel of the ridges down to the fertile alluvium of the river banks. The change in the native vegetation from one to another of these is very remarkable, indicating an adaptation for various crops. Long rank grass covers the moister portions of the bottoms, and there is always some timber close to the water, except towards the mouth of the Yakima. Those valleys north of latitude 48° are doubtless the best in soil and climate, crops doing admirably at Fort Colville without any irrigation. The lands immediately along the Columbia itself, from just below the mouth of the Spokane to near the Dalles, and all the adjoining region below the elevation of about 2,000 feet, seem available only for grazing without the assistance of irrigation. But it has, as well as the higher valleys, great advantages for effecting this object in the terraces which often partially form a 3t 18 BOTANY OF THE ROUTE. dam, and, with the immense and inexhaustible timber on the mountains, can be made to retain a supply of water both for this purpose and to assist in navigation in the mode suggested by Mr. Ellct, in the Smithsonian Contributions, for improving the navigation of the Ohio. The natural accumulation of alluvial soil in the lowest places would, Avithout doubt, make the banks of this river the most fertile instead of the most barren of all, were it not for the extreme dryness of the climate. Like the rich valley of the Nile, it may, by irrigation, hereafter support a population as great and flourishing as that of Egypt in her palmiest days. It has also the advantage that the worst land of the Great Plain is far superior to the deserts which border the Nile valley. In the chapter on the climate of the country along the route this question of cultivation will be found more fully discussed, and compared with other countries. The relations of climate to the natural productions of the central division of the Territory are very interesting, and although the data are still incomplete, they show that moisture must be the only thing wanting to produce a luxuriant vegetation. There being little rain, of course snows must be light, but, north of latitude 48°, begin early and cover the ground throughout winter, forming an excellent protection for winter grains, besides advantages for travelling, and do not become so deep as to prevent grazing. While at Fort Colville, as early as October 24, we had a fall of about six inches of snow, almost the first storm of the season. This, however, melted off in twenty-four hours, and we found that south of the Spokane river it had been replaced by rain. After October 1 there is a fall growth of grass, especially where the surface has been burnt over, and we found the hills near the Okonagan in October, and near the Walla- Walla in November, covered with the richest green herbage. As early as February 19, 1854, Lieutenant Grover found the grass " springing up plentifully" on the Spokane plain, while the forests he had just left north and east of that river were still obstructed by deep snows. The growing season begins and ends early, extending from about March 1 to June, like that of the fertile valleys of California. The time during which I collected on the central plains of the Territory, extending from August 16 to November 17, was the worst period of the year for that purpose. Yet in the small collection of eighty species of plants there are two new ones, (Astragalus seratinus and Malacothrix crepoides, ) besides several others of interest, showing that at more favorable seasons the botsnist may still obtain novelties in a field already mote explored than any other west of the Rocky mountains. Among mammals, all kinds of which were scarce, I can only mention one as new, (Hesperomys austerus.} Of birds, one is new, (Podiceps occidentalis^} others scarcely before known, (Picus alpolarvatus, Sittapygmaea,} although I never saw a region so poor in these animals during summer. After October the fall migration began to bring southward many interesting species, which our rapid travelling during the short days did not allow me time to collect. Dr. Le Conte has found several new insects among those obtained there, and the few reptiles and fish I succeeded in preserving furnish several new and interesting species. REGION WEST OF THE CASCADE MOUNTAINS. I now return to the western region of the Territory, including the entire surface west of the Cascade range, which I have left for the last description because it occupies the lowest portions of the Territory, and because my residence in it of two years gives me the means of describing it the most fully. Occasional extracts from my journal may show its striking peculiarities in a stronger light than mere methodical description alone. In descending the Columbia from the BOTANY OF THE ROUTE. 19 Dulles, on November 17, we found the mountains to rise very rapidly in height and become suddenly densely wooded ; the trees observed being usually of the species prevailing on tho western slopes of the range. This great mountain gap, unequalled in depth and extent by any on the continent, presents in some parts the perpendicular walls of the canon, in others the gradual slopes of a narrow valley. Even from the Dalles we could perceive a thick fog hanging in the gap, but were quite unprepared to find a heavy rain, which we entered long before reaching the Cascades, and which continued unceasing during the whole day and night following, when we reached Vancouver. Even after entering this rain we could see the bright unclouded sky of the plains eastward, but I thought the moist and milder air more agreeable than the cold dry climate we had just left. The change in the appearance of the country in the distance of a few miles was almost as great as I have since observed between New York and the isthmus of Panama in January, as we left the ground at the Dalles covered with snow, and entered a region of perpetual spring, with gigantic evergreen forests, tropical looking shrubs, and large ferns, Avhere several spring flowers were still blooming. Even the perpendicular rocks supported a green covering of mosses, *- PREFATORY NOTE. - No. 1. REPORT UPON THE INSECTS COLLECTED ON THE SURVEY. BY JOHN T. LECONTE, M. D. No. 2.

It is proper to state that much of the credit for whatever of value the papers may contain is due to the Smithsonian Institution. Professor Henry, the secretary, has afforded every assistance in his power to the expedition, in the way of office rooms, of free access to the library, and to the natural history collections of the institution, and of the time and personal assistance of its officers. The instructions of the zoological collectors; the classi fication of the materials collected; and the elaboration of their scientific descriptions and names, are all the work of Professor Baird, the assistant secretary, and of his immediate assistants. This gentlemen has also attended to the proper selection of subjects for illustration, and to the proper expenditure of the money set apart by me for this purpose. The engravings have been made by competent artists within the walls of the institution, and their excellence is the guarantor of the personal attention and interest of Professor Baird. The collectors of the party, Dr. Suckley and Dr. Cooper, have availed themselves of every opportunity to enhance the value of the collection, both while in the field and subsequently while residing in the west. They have also devoted much time to comparing and arranging the materials collected, and to adding to Professor Baird' s scientific descriptions many interesting notes upon the habits and peculiarities of the different species. These notes will be found in the several sub-reports prepared, with the exceptions above mentioned, by these two gentlemen, and herewith presented. ISAAC I. STEVENS. No. 1. REPORT UPON INSECTS COLLECTED ON THE SURVEY. BYJOHNT. LECONTE, M.D. INTRODUCTORYREMARKS. As early as the year 1829, many Coleoptera of the western coast of North America were made known by Eschscholtz, in his Zoological Atlas. This work was intended to contain descriptions of the copious scientific treasures collected by him during the voyages of Captain Kotzebue, of the Imperial Russian navy, during the years 1823-'26, and the results of the expedition, as well as the promptness with which they were made known, afford a lasting monument of the liberal policy pursued by the Russian government in the encouragement of intellectual pursuits, which, though not immediately connected with physical prosperity, are yet an unfailing standard of mental elevation. The death of Eschscholtz unfortunately prevented the completion of the work ; and from want of opportunity, his collections remained undescribed for several years. In the meantime, in 1843, Mannerheim published a Coleopterous fauna of California and Russian America, which contained descriptions of three hundred species. This was followed, at intervals, by three supplements, devoted to the Coleoptera of Russian America , and by the last of these, published in 1853, the total number of species known from that part of the continent was brought up to 540 species ; and by his labors, that portion of the fauna has indeed been more completely developed than that of any other part of this continent. Papers by Motschulsky, also published, like those of Mannerheim, in the Bulletin of the Imperial Society of Naturalists of Moscow, contain valuable additions to the entomology of Pacific North America. Our knowledge of the Coleoptera of Oregon and Washington Territories is still less complete, and with the exception of a few species collected by Dr. J. K. Townsend, and described by Harris, Erichson, G-ermar, and Reiche, consists of new material obtained almost entirely through the influence of the enterprising and zealous naturalists, Drs. Cooper and Suckley, of the present expedition. To George Gibbs, esq., of Steilacoom, I am deeply indebted for a beautiful collec tion, which, through the kindness of Dr. Suckley, arrived in time to be incorporated in the report. To Colonel George A. McCall, late Inspector General U. S. A., I owe my warmest acknowledge ments for a valuable series collected by him while performing his official duties in Oregon. Many years ago I examined the collection of Coleoptera made by Dr. Pickering and Mr. Titian Peale, during the expedition of the Peacock and Vincennes, under Captain Charles Wilkes, U. S. N. Among them were a considerable proportion of species found in Oregon and California, which at that time were new. The report has not been published ; but on looking over the notes made at the time by me, I find that there are in the collection very few species that have not since been obtained from other sources, and which are, therefore, comprised in the catalogue here given. 1Q 2 U. S. P. R. R. EXP. AND SURVEYS ZOOLOGY — 47TH PARALLEL. Nearly one half of the species found in Kussian America have become known to me hy the kind exertions of my scientific friends, Baron Chaudoir and Colonel Motschulsky ; and to the latter I am indebted for his careful comparison of a set of the Californian Coleoptera collected by me, with the original types of Eschscholtz, Mannerheim, and Menetries, by which I have been enabled greatly to increase the accuracy of my investigations. The species which remain unknown to me are marked in the catalogue with an inverted comma before the locality, to show that they are placed in the catalogue on the authority of other writers. The materials present, for actual investigation, in compiling this report, are therefore : 1. A series of more than two hundred species from Kussian America, examined and named by Count Mannerheim, sent me by Baron Chaudoir. 2. A smaller series, containing similar species, together with some Californian types of Eschscholtz, sent me by Colonel Motschulsky. 3. About fifty species collected by the late J. K. Townsend, M. D., in Oregon, and given me by Mr. Edwin Willcox. 4. A collection made at Fort Vancouver, by Colonel McCall. 5. The collections of Dr. Cooper, made in various parts of Oregon, but chiefly at Vancouver and Shoalwater bay. 6. The collections of Dr. Suckley, made principally at Steilacoom. *T. A collection made by George Gribbs, esq., at Steilacoom. 8. The collections made by myself, at San Francisco and San Jose. 9. Two collections made in the valley of the Sacramento by Mr. J. Wittick, and presented to me by S. S. Kathvon, esq., of Lancaster, Pennsylvania. 10. Two collections made, the one in the Sacramento valley, the other at San Francisco, by Mr. J. Child, also given me by Mr. Eathvon. 11. A small but valuable collection from the vicinity of San Francisco, given me by Mr. J. P. Wild, of Baltimore. The Staphylinidae are represented in the catalogue by species previously described ; the new species collected by me are so numerous, and frequently so closely allied to species of the Atlantic slope of the continent, which are also undescribed, that it appears to me of no advan tage to science to make them known separately, but rather to await the opportunity of time to place them in a general synopsis of the Staphylinidae of the United States by genera and tribes. I have, however, made use of them in constructing the tables of distribution of genera, num bered I and II. Several Curculionidae in my collection have not been described, for the reason that, with the arrangement given by Schonherr in his ' Genera et Species Curculionidum,' I am quite unable to refer them to appropriate genera, while the specific characters do not appear sufficiently remarkable to render them easily identified. The collections of Drs. Cooper and Suckley, as made during the survey of the 47th parallel, were placed in my hands for examination by the Smithsonian Institution, to which I am also under great obligations, for the opportunity of examining many other North American insects. The distribution of species in the northern part of the region which furnishes the materials for this report, presents no remarkable phenomenon. As in other northern lands, certain tribes like Adephaga, Staphylinidae, and Elateridae assume a greater preponderance in the fauna, from the fading out, of the groups more characteristic of warmer climates, while a greater INSECTS COLEOPTERA 3 number of species are found common to both continents. Of these latter, about one half are found on the Atlantic slope of America, while the other half have not yet occurred there. The number of species occuring on both sides of America is also largely increased in these northern regions, but with the exception of Epiphanis cornutus and Priognathus monilicornis, the genera of such species are distributed on both continents. On proceeding southwards to Oregon (and Washington Territory, which is, for purposes of convenience, always included when Oregon is referred to in these pages) similar phenomena may be observed, though on a diminished scale. The species of the eastern continent, not found on the Atlantic slope of America, have entirely vanished, and of the species common to both sides of both continents, but four remain. The number of species common to the Atlantic and Pacific slopes of America has greatly diminished, and among them Haplocliile pygmaea, Ligyrus gibbosus, Alaus myops, and Microrhopala vittata are the only representatives of American genera. Finally reaching California, the species common to the two continents are reduced to Silpha lapponica and Dermestes vulpinus, the species common to Atlantic and Pacific America have not diminished absolutely in number, but from the more complete and copious fauna known to us their relative proportion is much lessened. Among them, however, are found but few which extend their range to the Atlantic States proper, while the greater proportion are not found east of Kansas. Of American genera, Amblychila cylindriformis, Lachnophorus elegantulus, and Eurymetopon atrum are found in Kansas, or New Mexico, while Ligyrus gibbosus and two species of Diabrotica also extend to the Atlantic. Having thus passed in rapid review the distribution of species, as illustrated by tables III and IY, the much more important subject of the distribution of genera remains to be considered. The phenomena afforded by the study of seven of the most numerous families, I have endeavored to express in a numerical form in tables I and II. In Russian America the genera seem to follow to a certain extent the course already pointed out of the species, that is : the genera common to both continents have a much greater relative proportion, and among them a by no means insignificant part have not yet been found in Atlantic America ; but as some of them are characteristic of high northern latitudes, there is reason to believe that the number will be reduced by more thorough explorations in Labrador, Newfoundland, and the regions near Hudson's Bay. Of genera confined to America, but six or seven occur in Russian America ; of these but three, Pristodactyla, Epiphanis, and Priognathus, have been detected on the Atlantic slope. Pristodactyla might, indeed, be for the present excluded from the list of peculiar American genera, for two reasons : 1, a certain number of species classed by Dejean, with Agonum, and remarkable for having but two dorsal punctures, are in reality Pristodactylae, and until the species of Siberia are thoroughly revised, we are warranted in supposing that some of them may also be included ; but, 2, because the distinctions between Calathus and Pristodactyla, as observed by Lacordaire, are hardly sufficient to warrant the retention of the latter genus. In Oregon the eastern genera, not found in the Atlantic States, have diminished in number, but among them occurs Callisthenes, which is found in Kansas. The number of American genera has largely increased, even with our limited collections ; of them 14 are found in the Atlantic States, 2 in Kansas, while 8 are peculiar to Pacific America ; of the 14 found in the Atlantic States, Haplochile, Dichelonycha, Anelastes, and Alaus are the only ones not found within the tropics. 4 U. S. P. R. R. EXP. AND SURVEYS ZOOLOGY 47TH PARALLEL In California the genera of the eastern continent have increased absolutely, from more exten sive collections, over those found in Oregon, but do not attain the same relative proportion as those found in Russian America ; among them is one, Tryssus, a genus heretofore known only from Madagascar, and is thus far the sole representative of the tribe of Scarabaeidae, to which it belongs on this continent. The number of American genera has greatly increased, partly by the addition of genera found within the tropics, and partly by the introduction of a few peculiar genera ; the most remark able addition, however, is that of eighteen genera of Tenebrionidae, of which but two, Nosoderma and Blapstinus, extend into the Atlantic States, while only four others extend into Kansas or New Mexico. The genera found in the Atlantic States, and not in the tropics, are Thalpius, Axinopalpus, Dichelonycha, Anelastes, Perothops, and Melanactes. Another fact of great interest is the distribution of species within narrow limits observed in California. I am not able to exhibit the results in a tabular form, as collections have not been made with minuteness at a sufficient number of localities to give any definite results, but I can merely state my own experience, that but few species occurred at more than one place, and call attention to the fact that, in every collection made at a fresh locality, a large proportion of new species is found, while in Oregon, at points equally distant from each other, a greater unifor mity is seen. The analysis, therefore, conducts to the same results announced by me, in 1851, at the meeting of the American Association for the Advancement of Science ; the fourth proposition was, unfortunately, announced in too absolute terms, as the only two genera then known to me, Thalpius and Axinopalpus, were not considered as of sufficient importance to modify the result. Thalpius, indeed, is so closely allied to Diaphorus, that we may well expect some of the species of the latter genus to belong to it, while Axinopalpus is by many entomologists not separated from Dromius. The other four American genera common to California and Atlantic America, not found in the tropics — Dichelonycha, Anelastes, Perothops, and Melanactes — upon which I am now obliged to modify the assertion, were subsequently obtained. The four propositions stated by me in the essay mentioned are : 1. California constitutes a peculiar zoological district, with sufficient relation to the other districts of America to prove that it belongs to the same continental system. 2. This zoological district is divided into several sharply defined sub- districts, having a very close resemblance to each other. As the same mode of distribution obtains in the groups of islands adjacent to the western coast of America, we are led to believe — 3. That the local distribution of a small number of species is the characteristic of the eastern Pacific region, as the extensive distribution of a large number is the prevailing feature of the Atlantic basin . 4. The genera occurring in, but not peculiar to, this district belong to two classes : either (with the exception of Ergates) they occur on the Atlantic slope of both continents, or, if peculiar to America, they are (with the few exceptions above noted) also found within the tropics. [NOTE.— The Coleoptera collected by me at San Diego and other localities in the southern part of California have not been included in this report, as they more properly belong to the fauna of the Mexican Boundary, and will be contained in the report of the survey made by the Boundary Commission.] INSECTS — COLEOPTERA.

These three species, the only ones known, form two natural divisions, according as the thorax is short and depressed, (0. Dejeanii,) or oblong and moderately convex. The two species of the latter division resemble each other closely in form, size, and sculpture, the less deeply rugous thorax of 0. Audouinii at once distinguishes it ; the head of that species is also less deeply rugous between the eyes than in 0. californicus ; the elytra are more distinctly rugous, and there is an obvious difference in the size of the punctures of the elytra ; on close inspection, a similar character may be seen in 0. californicus, but much less distinctly.

California ; a specimen collected by Mr. Woznessensky, the only person by whom it has been found, was sent me in exchange by Dr. Klug, of Berlin. On comparing with a Texan species of Stenomorphus, yet undescribed, I find that the differences in the pos terior tibise, to which attention was called by Mannerheim, exist in part, but hardly to the extent indicated in his comparison between this species and S. angustatus Dej. The rows of spines visible in Stenomorphus are replaced by stout hairs, but the deep grooves on the inner face of the hind tibise are also present in the Texan species. In the one now under considera tion, the anterior tibias are internally fringed with long dense white hair, (Tab. — Fig. a,) while in Stenomorphus only a few scattered bristles can be seen. This difference, with that of the form, seems to indicate that the genus Agaosoma should be preserved, at least for the present. STENOLOPHUS Dej.

This species long ago described by Fabricius, probably from the collection of Captain Cook's voyage, has been lost sight of in modern times, or rather has been made known under other names ; the insect described by Fabricius was in Sir Joseph Banks' collection, and the figure given by Olivier is quite recognizable.

Fort Vancouver, Dr. Cooper ; Sacramento, California, Mr. Wittick. Shorter and less convex than C. calidum, approaching in form some species of Callisthenes ; the thorax is hardly nar rowed behind, and the posterior angles are distinctly, though broadly produced. The wings are well developed, and the other joints of the antennae are equably pubescent. The intervals between the rows of punctures of the elytra are marked with a few transverse striae ; the spaces between the impressed foveae are distinctly elevated, and smoother than the other parts of the elytra. The specimens collected by Dr. Cooper, in Oregon, differ from those found in California, by the less distinct green tinge of the elytra, which are also less densely rugous ; on this account I was disposed to regard them as indicating a species different from that of Eschscholtz, but the subsequent receipt of two specimens from California, which, with many other valuable species, were presented to me by Mr. S. S. Kathvon, enables me now to pronounce these differences as INSECTS COLEOPTERA 31 merely individual. One of the characters mentioned by Eschscholtz, that the spaces between the rows of punctures of the elytra are alternately more elevated, seems liable to variation : in one specimen it is seen ; in another, the middle interval in each space between the catenated rows appears a little broader than those next the elevations ; but in the other specimens no dif ference in breadth or elevation can be perceived.

This species, by its short robust form, and by the absence of wings, simulates Gallisthenes, but the antennae are as in other species of Calosoma. Body black, without metallic lustre. Head elongated, rough with confluent wrinkles and punctures ; antennae with the third joint strongly compressed, twice as long as the fourth, fifth and following joints entirely pubescent. Thorax more than twice as wide as the head, and fully twice as wide as its length, not convex, margined, with the sides somewhat depressed behind, but not reflexed ; base transversely impressed, and faintly bifoveate ; middle part truncate, posterior angles moderately produced, hardly acute at apex. Elytra oval, moderately convex, a little wider than the thorax, marked with faint approximate striae, which are strongly punctured ; the narrow interstices are also marked, each, with a row of punctures equal to those of the striae ; in certain lights three rows of very indistinct foveae may be seen in the usual position.

This interesting genus was founded upon Blethisa Zetterstedtii Gryll., a rare insect of northern Europe. From the rarity of this species, authors who have not had an opportunity of examination have much mistaken the haracters of the genus. So far from being allied to Blethisa, it has the anterior acetabula 32 U. S. P. R. R. EXP. AND SURVEYS ZOOLOGY 47TH PARALLEL. dehiscent, and the mesosternum at the tip compressed and carinate as in Notiophilus. From the latter genus it differs by the very short emarginate labrum, by the more distinct, but also bicuspid mentum-tooth, and by the less prolonged prosternum. Of the anterior tarsi of the male, the first and second joints are dilated ; the third and fourth are small an equal. AMPHIZOIDAE. Coleoptera pentamera, pedibus ambulatoriis, antennis filiformibus; prothoracis episternis a noto sutura divisis, acetabulis anticis postice hientibus ; coxis anticis et mediis globosis, posticis transversis ad marginem corporis extensis, contiguis, antice truncatis, postice ad insertionem pedum elevatis ; mento magno emarginato, cum gula omnino connate, (sutura nulla ;) maxillis lobo interno curvato acuto, intus parce spinoso, galea elongata palpiformi exarticulata ; abdo- mine sex-articulato, articulis anterioribus tribus connatis. In the above diagnosis I have placed an assemblage of characters which seem fully to justify the establishment of a separate family for the reception of the very remarkable Amphizoa insolens. A detailed description may be found in the 6th volume of the Proceedings of the Academy of Natural Sciences of Philadelphia, (p. 227;) I there express the opinion that it would not enter any family of Adephaga as then constituted, and brief allusion was made to the large size of the posterior coxae, which cut off all connexion between the metathorax and the ventral abdominal segments, as indicating an affinity with the Dytiscidae, a view which, also, seemed to be confirmed by the subglabrous antennae ; at the same time the ambulatorial legs showed a tendency towards the Carabidae. Since there appeared to be, however, no very strong resem blance in the structure of the legs, though ambulatorial, with those of Carabus, I did not insist very strongly on the latter affinity. Lacordaire has, in the excellent work now being published by him on the Genera of Coleoptera, (Vol. 1, p. 409,) introduced an abstract of the description given by me, but not considering the characters sufficiently important to define a new family _, has placed the genus as a tribe of Dytiscidae, equal in value to Pelobius. A misunderstanding of some expression used by me has, unfortunately, led him to place in the diagnosis of the tribe, ' hanches posterieures . . non contigues au cote interne;' which is not the case ; the coxae come together on the median line, as in Pelobius, Dytiscus, &c., but differ in the anterior margin being transverse and rectilinear, while in all true Dytiscidae (Haliplus and Cnemidotus being excluded) the anterior outline is rounded ; the posterior lobes above the insertion of the hind feet are more distant and less elevated. The second ventral segment is prolonged anteriorly in an obtuse angle, and articulates with the coxae, so that the first segment is entirely lateral, as in Carabidae. From this it results that no part of the metathorax reaches the ventral segments of the abdomen, all communication being cut off by the coxae extending to the sides of the body. Another character not found in any other Adephagous insect, is the complete union without any visible suture between the gula and mentum ; this fact is of great importance, and upon it the argument for the separation of this as a new family must to a considerable extent rest. I regret that it was omitted in my former description, although observed while making a re- examination for the present report ; to Dr. Schaum, also, I owe my acknowledgments for a INSECTS COLEOPTERA. 33 very interesting letter on Amphizoa, in which my attention was called to this omission, and to the misstatement that the galea of the maxillae is biarticulate ; a more careful view shows that it is in reality undivided, and that I was deceived by a cross reflection of light. With regard to the affinities towards the Tenebrionidae, upon which Dr. Schaum lays great stress, I confess that I have failed to appreciate them ; the sculpture of the femora and tibiae are, indeed, similar to that of Tentyria, but the joints of the tarsi are puffed out below, and not concave, with a marginal series of short spines, as in Tentyria and Carabidae. The anterior coxae are entire in all Tenebrionidae, while in Amphizoa they are open ; the posterior coxae are also entirely different in form and position from all Tenebrionidae known to me. The antennae, as observed by Dr. Schaum, though nearly glabrous, are not those of a Dytiscus, but still less are they those of a Tenebrionite ; still it must be admitted that the homogeneous structure of the outer articulations, without any lateral spongy portion resembles more nearly what is seen in Dytiscidae, than in any other family of Coleoptera. To conclude then this portion of the essay, I would briefly state, that the anomalous structure of Amphizoa is such as to exclude it absolutely from any known family, and that its position must be in a new family, between Carabidae and Dytiscidae, without any distinct point of osculation with either ; Pelobius on the one hand, and Opisthius on the other being the nearest allies. As these conclusions are much at variance with those duduced by others, I take the liberty of transcribing a portion of Dr. Schaum's letter, with a view to hasten as far as possible the time of harmonizing the diverse results, which are always obtained in a case of such difficulty. ee Amphizoa has, indeed, the posterior coxae of Pelobius, but there seems to be a greater dif ference between its coxae and those of the typical Dytisci than between its coxae and those of Ozaena, for instance. This is, however, the only character which I can find to agree with any Dytiscus. The antennae are glabrous, but they are the antennae of a Heteromerous insect, and not those of a Dytiscus. All the other characters seem to me to be at variance with the water beetles ; configuration of prosternum, metasternum, legs, number of visible abdominal segments, and above all the parts of the mouth ! The legs are also different from the type of the Carabidae ; they are glabrous and the joints are prefectly those of Tentyria. Even the dilatation of the coxae is found in the the Heteromerous tribe. But what now is this most anomalous insect? In my opinion a most extraordinary Carabus with many characters of the Heteromera. In spite of the exarticulated exterior lobe (of the maxillae) it must be referred to the Adephaga on account of its mentum, the number of united abdominal segments, and the number of tarsal joints. I prefer much more to put it among the Carabi than among the Dytisci, on account of the constricted thorax, the sternal segments, the number of abdominal segments, the texture and structure of maxillae, and the ambulatorial legs. The analogies to the Heteromera are most striking ; antennae, legs, even the coxae are those of Tentyria. It is interesting that this form occurs in California, where the Heteromerous type is so prevalent." Having now laid both opinions before the reader, I leave the subject to the consideration of systematists, illustrated by the excellent figures made by Mr. Hitchcock of the various parts of the under surface, PI.

Sc. 6,) in whicli the front is transversely margined and angularly impressed, and the proster- num compressed with the striae distinct. The anterior tibise were probably four-toothed, as in S. bigemmeus, but the teeth, with the exception of one at the middle are entirely worn off. TERETRIUS Er. T. dbliquulus, oblongus, cylindricus, niger nitidus punctatus, elytris striola obliqua ad basin versus humeros impressis ; anteiinarum clava, pedibusque piceo-rufis, tibiis anticis subito dilatatis, sexdenticulatis.

Long. "10. One specimen, San Jose, California. This species is a little wider than E. parallela Lee., but is narrower than usual ; the thorax is about twice as wide as its length ; the base is broadly rounded in the middle, and slightly sinuate towards the basal angles, so that the latter become nearly rectangular, and not rounded. The elytra are about one-half longer than wide.

Long. '10. Oregon. Very similar to M. rufimanus, but differs in the sides of the thorax being more rounded, with the posterior angles more obtuse ; the anterior tibiae are narrower, and the crenulation towards the base becomes so fine as to be hardly visible.

Long. -68. One specimen, Sacramento, Mr. Wittick. This is the first appearance of the group Macro- phyllidae in America ; it differs from the genuine Melolonthidae by the segments of the abdo men being separate, with distinct sutures. On account of the 9-jointed antennae with three jointed club, I have referred it to a genus constructed by Erichson (Ins. Deutchl.) for some South African species ; the ungues are cleft, (as required by his description,) each division being broad and acute, the inferior one is a little short ; the tarsi are longer than the tibiae, and the last joint is armed with a small tooth beneath, near the tip. The labrum is large and emargi- nate, and the epimera of the metathorax are broad. DIPLOTAXIS Kirby.

On the eve of my departure from tbe country, perfect specimens of tbis most curious genus have arrived, but do not, in the hasty manner in which I am obliged to study them, throw much light upon its affinities. Although agreeing with Gcotrupidae in the eleven-jointed antennae, the form of the antennae is entirely anomalous in that and allied groups, and the small size of the oral organs would seem to indicate a new group between Geotrupidae and Copridae. These specimens are much smaller than the other one, being only .8 of an inch long. The figure is made from the one first obtained, but the antennae are supplied from the smaller specimens, those of the former being very imperfect, though still sufficiently preserved to be correctly described in the text, having only four long leaves, and one short one in the club. These differences may be sexual, at least no adequate specific difference on comparison, unless it be in the thorax> which, in the large specimen, is very finely and sparsely punctured, while in the small ones it is quite densely punctured and clothed sparsely with long hairs like those on the margin. INSECTS COLEOPTERA. 41 One specimen, California, Dr. Heermann ; given me by Mr. Haldeman. As the oral organs and the abdomen are destroyed, I cannot tell whether this genus belongs to the Dynastides or Geotrapides ; in either case the four-jointed antennae club is equally remarkable. The affinities, as far as I can understand them, seem to be rather with Geotrupes. CANTHON Illiger.

D. pectorosa, supra obscure fusco-aenea, capite inaequali grosse punctate, thorace latitudine plus duplo breviore, valde canaliculate, fere bicostato, (costis laevibus), ad latera inaequali, grosse confluenter punctate, lateribus valde rotundato-dilatatis, postice breviter sinuatis, angulis posticis acutis, elytris thorace angustioribus lateribus parallelis, postice prolongatis integris, foveatim striato-punctatis, rugosis, interstitiis dense punctatis, spatiis parvis irregularibus nitidis parum elevatis, praecipue versus scutellum notatis. Long. '64. Oregon, Dr. Suckley, Somewhat similar to D. tenebrosa, but the thorax is much more dilated, and the smooth spaces of the elytra are not distinct, and are irregularly connected. The terminal segment of the abdomen is truncate, strongly bicostate, with four deep subapical foveae. The under surface is dark brassy, with large rugous punctures of a brighter color. D. crassicollis, supra obscure cinereo-aenea, capite inaequali grosse punctato thorace latitudine plus duplo breviore, fere quadricostato, costis exterioribus interruptis, utrinque late excavato, lateribus valde dilatatis, postice longius sinuatis, angulis posticis paulo acutis ; elytris thorace haud latioribus, humeris rotundatis lateribus subparallelis, postice breviter caudatis et sub- bidentatis, grosse indistincte striato-punctatis, interstitiis densissime punctatis, alternatim plagis oblongis elevatis laevibus ornatis. Long. '66. Steilacoom, Dr Suckley. The elytra are sculptured exactly as in D. tenebrosa, but the rows of punctures are less obvious ; the posterior prolongation is shorter, and slightly bidentate ; the thorax is much more dilated on the sides, and more deeply excavated ; in one specimen a small callus is seen in the middle of the dorsal channel. The terminal ventral segment of the male is rounded, but in the female has two acute narrow incisures. POLYCESTA Esch. P. californica, nigro-aenea, elongata, capite grosse confluenter cribroso, haud excavato, thorace brevissimo antrorsum angustato, lateribus obtuse angulatis, angulis posticis obtusis haud rotundatis, inaequaliter cribrato, vage tricanaliculato, canalis externis antice abbreviatis, ante scutellum linea brevi longitudinal! impresso ; elytris margine basali, costisque quatuor elevatis, interstitiis confertim punctatis et biseriatim grosse punctatis lateribus antice late rotundatis, dein parallelis, humeris obtusis. Long. '75. Sacramento, Mr. Wittick, one specimen. This species much resembles a larger one found in Texas and a smaller one from Alabama ; but from each it is distinguished by the front not being concave and by the more regularly and densely punctured spaces between the costae of the elytra ; the series of punctures adjacent to the costae are smaller and more regular ; the three inner costae are smooth, while the external one is punctured ; the tips of the elytra are broken, some of the small teeth of the lateral serration yet remain. PEROTHOPS Esch. P.

In form this species resembles P. mucidus, but the pubescence is brownish gray and more sericeous. The thorax is more convex ; and the deep transverse impression between the eyes is very different from the vague rounded one seen in P. mucidus. The discovery of a second species of this curious genus is of great interest, and it gives me pleasure in naming it to commemorate the disinterested services of the gentleman by whom it was collected. ATHOUS Esch. A scissus, ater nitidus, tenuissime pubescens, thorace latitudine longiore, confertim punctate, lateribus fere rectis parallelis modice reflexo-marginatis, angulis anticis oblique truncatis ; elytris profunde striato punctatis, interstitiis parce punctatis, antennaruin articulo 3io triangulari quarto paulo breviore ; tarsis haud lobatis.

Long. -2. San Francisco, Mr. Child, one specimen. This species belongs to the division in which the lateral suture of the prosternum is excavated anteriorly. It may be placed in the vicinity of L. basillaris, Lee., (Trans. Am. Phil. Soc. 10, 431,) though the legs are only in part testaceous. The posterior angles of the thorax are rectangular and slightly testaceous. COKYMBITES Latr. (emend. Lee.) C.

Long. -53. Steilacoom, George Gibbs, esq., one specimen. It affords me much pleasure to dedicate this beautiful species to Dr. Suckley, my esteemed friend, who, by his active and scientific zeal, has added so many new objects to the fauna of the regions explored by him. Although resembling in many characters, as well as by its form, C. aratus, Lee., (Trans. Am. Phil. Soc. 10, 438,) this species seems, from its dilated scutel and glabrous body, to indi cate a new section of the genus, to be placed between the first and second established by me. C. festivus, crassiusculus, vix tenuiter pubescens, niger, thorace quadrato, modice convexo, lateribus antice rotundatis, angulis posticis paulo divaricatis, confertim punctato sanguineo, vitta lata dorsali, margine laterali prosternoque nigris ; elytris testaceis, sutura (antice latiore,) INSECTS COLEOPTERA. 47 macula elongata a humero fere ad medium extensa, fasciaque postice concava pone medium nigrisj strigaque postica submarginali fusca ornatis striis profunde punctatis, interstitiis parce punctulatis ; abdominis lateribus sanguineis, pedibus ferrugineis, antennis fuscis, articulis tribus baseos ferrugineis. Long. '53. One specimen, Steilacoom, George Gibbs, esq. Nearly related to E, cruciatus of Europe and to C. pulcher Lee., (Trans. Am. Phil. Soc. 10, 440,) but sufficiently distinct by the fore going characters. The red margin of the abdomen is gradually widened behind, so that the last joint is red with a large basal black spot ; each segment is also margined with red ; the anterior lobe of the prosternum is partly red, and the black extends beyond the prosternum upon the pleuras, which are thus red with black margins, as in C. pulcher. AGRIOTES Esch. (emend. Lee.) A. macer, valde elongatus, ater opacus pubescens, thorace latitudine sesqui longiore, lateribus parallelis, antice paulo rotundatis, confertim punctato, transversim minus convexo, elytris striis punctatis, interstitiis sat dense punctatis, antennis articulis 2ndo et 3io coniunctis 4to aequalibus. Long. '32. Shoalwater Bay, Dr. Cooper. Very closely resembles A. oblongicollis, (Dolopius oblongi- collis Mels. ,) but the thorax is less convex transversely, and the feet are black. ELATER Linn, (emend. Esch.) E. rhodopus, ater breviter griseo-pubescens, thorace confertim punctato, postice subcanali- culato, elytris striis vix impressis punctatis, interstitiis confertim rugose punctulatis, pedibus antennisque ferrugineis, his articulo 3io secundo fere duplo longiore. Long. '45. Steilacoom, George Gibbs, esq., one specimen. Of the same form as E. luctuosus, Lee., (Trans. Am. Phil. Soc. 10, 466,) but differs from that, as from all the species there described, by the less deep elytral striae, which, towards the tips, are represented only by rows of punc tures. E. caprella, elongatus, ater cinereo-pubescens, thorace latitudine longiore, antrorsum angus- tato, lateribus antice rotundatis, sat dense punctato vix canaliculate ; elytris macula basali, altera angulata ante medium, tertiaque rotundata ad dodrantem flavis, striis punctatis, inter stitiis planis rugose punctatis, antennis articulis 2ndo et 3io aequalibus, pedibus testaceis. Long. '25. Shoalwater Bay, Dr. Cooper. Very similar to E. stigmosus Lee., (Trans. Am. Phil. Soc. 10, 4T2,) but the strise of the elytra are not so deep, and the basal spot is not connected with the angulated spot, which rises along the suture nearly to the scutel ; the posterior spot is larger and more rounded ; the thorax is more distinctly narrowed anteriorly. Varieties were found in which the basal and angulated spots are obsolete, or even entirely wanting. ADELOCERA Latr. A. aurorata. A specimen found at Steilacoom by Mr. Gibbs agrees in every respect with the description made by me from the typical specimen found in New Hampshire by Dr. Harris ; as I have not a specimen in my collection, I cannot assure myself of their identity by a direct comparison. 48 U.

Long. -4. Sacramento, Mr. Wittick, one specimen. This species belongs to the division named Pelo- nium, by Spinola, and although, by the colors of the upper surface, it immediately recalls E. damicorne, on comparison they are found to possess hardly a single character in common. PTINUS Linn.

Long. '73. Tab. I, fig. 19. San Francisco ; given me by Mr. J. P. Wild. This species differs from E. Stoutii Lee. by the thorax being more convex, opaque, and as strongly granulate in the middle as at the sides, while in E. Stoutii the middle of the disc is shining and not very densely punctured. Upon E. Stoutii I formerly constructed a Genus Allococnemis, which I considered allied to Nemosoma, but, on finding it to be identical with Exops, made the necessary correction ; but in doing this I was misled by Erichson's opinion, in Agassiz Nomenclator Zoologicus, that Exops is synonymous with the previously described Polycaon Laporte ; the latter, as I am assured by Prof. Lacordaire, is an entirely different genus, which really belongs, as stated by Erichson, to the Melyridae. NYCTOPORIS Esch. N. galeata, atra, opaca, capite cristato, varioloso, thorace confluenter varioloso, quadrifoveato, foveis internis profundioribus, lateribus antice valde rotundatis, elytris cristis interruptis aequa- liter elevatis. Long. -5 — '6. Tab. II, fig. 1. Very abundant at San Francisco, under bark of oak trees. Resembles N. cristata'Esch., but, on comparison with a specimen of the latter, sent me by Col. Motschulsky, I find the following differences : The thorax is wider than long, and considerably rounded on the sides before the middle, while in N. cristata the length is equal to the breadth, and the sides are only moderately rounded. The tubercles, into which the crests of the elytra are broken, are much closer, and the crests are less elevated ; the intervals are each marked with a row of elevated punctures. NOSODERMA Sol.

I formerly considered this as a geographical variety of E. obscura, but it differs in having a larger and less convex thorax. I am not yet sufficiently advanced in the study of this very difficult genus to determine whether it should be placed as a species or as a race.

By the larger size of the spur of the anterior tibias, it tends towards E. tricostata, and several nondescript species. E. cordata. Specimens of three forms, allied to this species, were obtained in Oregon, and, although evidently differing from those collected by me in California, I am not able to decide regarding the propriety of separating them. They may be known by the thorax being more broadly dilated, and more regularly rounded on the sides, although equally densely and coarsely punctured ; the posterior sinuation is therefore much shorter, although the basal angles remain rectangular. The other distinctions are as follows : 1. E. rotundipennis. Thorax very much constricted behind, fully one-half wider than lo ; elytra as coarsely, but less densely punctured. Length, '45 — '55. 2. E. stricta. Thorax less suddenly, but very much constricted at base, fully one- alf wider than long ; elytra more coarsely and less densely punctured. Long. '62. 3. E subligata.

Long. '9. Tab. II, Fig. 5. Mann. Bull. Soc. Imp. Nat. Moscou, 1843. Oregon. Nearly allied to a nondescript found in the northern Atlantic States, but differs by the less coarse punctures of the head and thorax, as well as by the latter being much narrowed towards the base. The punctures of the stride of the elytra are finer and more closely placed. This genus may be distinguished from its allies by the mentum being transverse, broader anteriorly, .and obtusely rounded, flat or slightly concave. PLATYDEMA Laporte.

In S. seniculus the rostrum is concave for nearly its entire length, and is not at all narrowed at the base. The color of the scales is cinereous in S. seni culus, and dirty yellowish brown in the present species. ALOPHUS Schonh.

On comparing a specimen from Sitkha, sent me by Baron Chaudoir, and one collected by Dr. Cooper on the journey from Vancouver to Yokolt, with A. alternatus Say, found at Lake Superior, I find them entirely different. The species from Oregon and Kussian America has the sides of the thorax subserrate and the apex strongly constricted ; the body is, also, more elongate, and the thorax is much smaller. A. didymus approaches it more nearly ; the thorax of that species is not at all narrowed towards the base, and the sides are not serrate. INSECTS COLEOPTERA. 55 LISTRODERES Schonh.

Long. '53. One specimen, Vancouver, Colonel McCall. The middle groove of the rostrum commences in a fovea between the eyes, and extends to the apex ; the lateral grooves are in front of the eyes, they are broad behind, and gradually narrowed anteriorly, vanishing a little beyond the middle ; the intermediate grooves are vague and anterior. The antennal grooves extend to the inferior part of the eyes, and are deep ; the two basal joints of the funiculus are elongate, the second is one-half longer than the first, and twice as long as the third. This species cannot be a Hylobius, but I do not know where to place it ; and while the family of Curculionidae is in such inextricable confusion as has been produced by the generic descriptions of Schonherr, it is absurd to establish any other genera, except upon the most remarkable characters. The characters, however, seem to be nearly those of Geonemus.

The specimen collected by Dr. Townsend was given to me by Mr. Willcox, as Barynotus torpidus of the Berlin Museum ; but the species belongs as little to Barynotus as to Hylobius. The prothorax is lobed behind the eyes ; the rostrum is longer than the head, with the antennal groove very short and slightly flexed. The antennae are slender, with the first and second joints of the funiculus elongate, the others rounded, short and equal. PTOCHUS Schonherr.

Long. *41. San Francisco, Mr. Child. Also related to the preceding and to the next species, but differs by the thorax being less densely punctured. The elytra are more coarsely and less densely punctured towards the base than in A. lugens and fusca, resembling in this character A. sub- aenea Lee., from which it differs by the thorax being broadly rounded, and not angulated at the sides. A. tumida, cyaneo-atra pubescens, capite thoraceque confertim punctatis, hoc linea dorsali laevi, latitudine breviore, convexo, lateribus postice parallelis, antice valde rotundatis, ad apicem valde constricto et tubulato ; elytris antice fortiter minus dense, postice subtilius punc tatis, a basi paulo angustatis postice obtusis.

Long. '96. Steilacoom, one specimen, Mr. Gibbs. Of the same form as T. Schaumii Lee., but the elytra are not obliquely truncate at tip. The elytra of the male are therefore probably slightly nar rowed from the shoulders. The fourth joint of the antennae is a little shorter than the third, and one-half as long as the fifth.

In one specimen the third joint of the antennae is entirely black ; in the other it is pale at the base, like the following ones. This species closely resembles L. obliterates, but the thorax is shorter and more broad behind. The impressions are much stronger, and the disc is separated from the base by a sudden declivity. The basal margin is yellow ; and on the elytra there is no trace of the two spots before the middle, seen in S. obliterata, and the apex is not at all rufous. The testaceous sides of the thorax and annulated antennae were not mentioned in the descrip tion given by me of Strangalia obliterata, (Journ. Ac. Nat. Sc. 2d ser. 1, 328,) as, on account of the very dark color of the only specimen then known to me, they were not observed.

Differs from the description of P. spinicauda by the tips of the elytra being not crenulated, as well as by the different arrange ment of the tubercles of the elytra. They form five series, of which only the outer one is entire ; the others contain only three or four tubercles ; the sutural one is indistinct, the second ends just behind the middle, the third and fourth commence about one- third from the base, and end at one-fifth from the apex ; the scutellum and a little thoracic line anterior to it are densely clothed with yellow hair.

Hind feet nearly as long as the skull. Tail one-half longer than head and body. Color above, dark sooty brown, mixed with hoary ; beneath, greyish white ; tail silvery white beneath. Head and body 2.10 ; tail 3. But one specimen of this species was obtained during the expedition ; this, according to the label now attached, was found at Fort Vancouver, but I am inclined to consider this a mistake, and that it was really taken while swimming under water in a lake near the summit of the Cascade mountains, August 31, 1853. SOREX VAGRANS, Cooper. BAIRD, Gen. Rep. Mammals, 1857, 15. SP. CH. — Third upper lateral tooth smaller than the fourth. Above, olive brown, washed with hoary ; beneath, dusky yellowish white ; sides a little paler than the back. Head and body 2 inches ; tail 1.75. Hind foot about .47 of an inch. Specimens were obtained at Shoalwater Bay, W. T. SCALOPS TOWNSENDII, Bach. Oregon Mole. Scalops townsendii, BACH. J. A. N. S. Ph. VIII, 1839, 58. AUD. & BACH. N. A. Quad. Ill, 1853, 217 ; pi. cxlv. BAIRD, Gen. Rep. Mammals, 1857, 65. SP. CH. — Teeth 44. Eye small, but not covered by the integument. Tail rather scantily haired. Nostrils opening on the upper surface of the tip of the snout. Palm large and broad. Color nearly black, with faint purplish or sooty brown reflection. (Sometimes, perhaps, glossed with silvery?) Moles are not common in any part of the Territory I have visited. Two specimens were obtained at Shoalwater Bay, where they burrow more like the gophers than the S. aquaticus, throwing up little mounds at a yard or two apart, though they sometimes in soft ground formed continuous galleries just beneath the surface. 10 Q 74 U. 8. P. R. R. EXP. AND SURVEYS — 47TH PARALLEL. FELIS CONCOLOR, L. American Panther. BAIRD, Gen. Rep. Mammals, 1857, 83. The cougar, incorrectly called panther, and American or California lion. This ferocious and blood-thirsty animal is very common in the Territory, where numbers are killed every year. It is more dreaded for its depredations on stock, however, than for a disposition to attack man, of which I never heard of an instance unless when it was wounded or in defence of its young. The Indians have a great fear of it, partly, no doubt, mixed with the superstitions which influence them so much. But in California, where it is abundant and grows to a great size, the hunters agree that it will always "vamose" when met with, while, if a hunter suddenly meets a "grizzly," he considers it the "better part of valor" to "vamose" himself. I prepared a skin and skull of a young male cougar that was killed in February, 1854, at the "Cascades" of the Columbia. It had stolen a large hog, and when pursued and shot at several times, finally leaped on to a high stump, whence a rifle ball through the forehead soon brought it down. It being the rainy season, and no means at hand of drying the skin artificially, it was unfortunately spoiled. This one measured 7 feet 4 inches from nose to tip of tail, the tail itself being 2 feet Y inches long. Height at fore shoulder 3 feet. Many have been reported in the papers as measuring from 9 to 11 feet in total length. The old idea that no feline animal will voluntarily take to the water, though now contradicted by many proofs, is still prevalent. In this animal we have an instance to the contrary. A steamboat descending the Columbia river met with one swim ming across where the river was at least a mile and a half wide, and without difficulty the men succeeded in capturing it by means of noose thrown over it. It was sent to California, where I saw it exhibited in December, 1855. It was then full grown, very fat, and with beautiful glassy fur of a rich brown color. A few of the black stripes, more marked in southern specimens, could be seen along the sides and legs where the white of the under parts joined the brown. It was restless and playful, but with that treachery characteristic of the race in every movement. Its keeper ruled it with a rod of iron, to which it always showed strong objections by growling, spitting, and obstinately refusing to obey his commands as long as it dared to resist. Though thought to be common in many places where I have hunted, I never had the satisfaction of meeting with one in its native wilderness or even of hearing its terrible scream. LYNX FASCIATUS, Raf. Red Cat. Lynxfasciatus, RAF. Am. Month. Mag. II, Nov. 1817, 46. BAIRD, Gen. Rep. Mammals, 1857, 96, Tiger cat, LEWIS & CLARK, Travels, II, 1814, 167. SP. CH. — Fur very soft and full. Ears pencilled. Color, rich chestnut brown on the back, a little paler on the sides and on the throat. A dorsal darker collar on throat, as dark as the sides. Region along central line of belly (rather narrow one) dull whitish, with dusky spots extending to lower part of sides. No spots or bands discernible on the upper part of sides. Ears black inside, with a very inconspicuous patch of grayish. Terminal third of tail above, black. The tiger cat of Lewis and Clark is very abundant in the forests of Washington Territory. The numbers that will resort to a farm yard, in a retired situation, for prey, is wonderful. One man told me that he had killed at his place, during one season, no less than fifteen, a large herd of young pigs being the attraction. His dog, but little larger than the wild cats, would boldly attack them, and though sometimes severely scratched, always came off victor. All that I have seen were very thin, so that they probably do not find much food in their forest ZOOLOGY MAMMALS. 75 haunts, where the blue grouse must be the largest game they can capture. In the fall they, no doubt, feast, like many other animals, on the multitudes of dead salmon washed up on river banks. I only once saw one alive, which was walking along a fallen trunk of a tree, whose top lay in the water, trying to get at a flock of half-fledged sheldrakes. It was so intent on the game that it did not notice our canoe silently and rapidly approaching it. The Indian in the bow startled it from its pursuit by lodging a charge of buck-shot in its side. It fell into the water, but soon recovered and attempted to climb out again. A stroke of a paddle stunned it, but it was sometime before it died, showing great tenacity of life. While travelling on the Columbia, I have heard in the densely forest clad mountains near its mouth, a loud screaming, answered from the hills around, which I was told was caused by the wild cat. This was always before sunrise, and the number was too great to have been caused by panthers. LYNX RUFUS. American Wild Cat. Felis ruffa, GULDENSTAEDT, Nov. Comm. Petrop. XX, 1776, 499. BAIRD, Gen. Rep. Mammals, 1857, 90. Lynx rufus, RAF. Am. Month. Mag. II, 1817, 46. AUD. & BACH. N. A. Quad. I, 1849, 2 ; pi. i. Sp. CH. — Fur moderately full and soft. Above and on sides pale rufous, overlaid with grayish ; the latter color most preva lent in winter. A few obsolete dark spots on the sides, and indistinct longitudinal lines along the middle of the back. Collar on the throat like sides, but much paler. Beneath, white spotted. Inside of fore and hind legs banded. Tail with a small black patch above at the end, with indistinct subterminal half rings, inner surface of the ear black, with a white patch. In California the wild cat is no less numerous than in Washington Territory. During a stay of six weeks in that country, in the fall of 1855, 1 saw two, and heard of many others being killed. The country being more open, they are much more easily hunted than in the north, and often appear in the open prairie in the day time. One I met with while hunting hares, about noon, and where I had been shooting several times the same morning. Two of us tried to steal upon it from opposite sides, but, as there was no shelter, it saw us and galloped off rapidly to a dense thicket near by. The same day, having obtained dogs, it was "treed" and shot. Many had been already killed near by as they came down from the wild mountains to the farm. They often sat in some thicket convenient to the house, and during the day succeeded in catching many fowls that unwarily approached their lair, as the occasional screaming and confusion among the poultry testified. When the owner had dogs, there was generally no difficulty in driving the cat up a tree, and there shooting it. CANIS OCCIDENTALS. Large Wolf. BAIRD, Gen. Rep. Mammals, 1857, 104. One or more species of wolf is found west of the Cascade mountains, but I could never obtain a specimen. They are of very large size, and howl in a loud dismal tone, very different from the yelping bark of the "coyote/' which I never heard in the forest covered regions. They are said to be of a light gray color, and instances are related of their pursuing and devouring men, especially in cold winters. It seems strange that while two or three species of wolves, besides foxes, are very abundant in the prairies and deserts east of the Dalles, where there is no game larger than hares and sage fowl, they seem to shun the regions inhabited by elk and deer west of the mountains. They have, however, become more common since the introduction of sheep in some districts. 76 U. S. P. R. R. EXP. AND SURVEYS — 47TH PARALLEL. PVULPES MACROURUS, Baird. Red Fox. BAIRD, Gen. Rep. Mammals, 1857, 130. The same remarks apply to foxes as to wolves, respecting their range. I never saw even the skin of one killed west of the Cascade Range, though they are undoubtedly found in small numbers. The great difficulty of hunting such animals in the dense forests is one reason, and the general substitution of strychnine for traps another why their skins are less often seen, many being needlessly afraid to skin an animal killed by strychnine. MUSTELA PENNANTII, E r x 1 . Fisher. BAIRD, G n. Rep. Mammals, 1657, 149. "Fisher " skins are brought by the Indians from the mountains. They do not, however, seem to be common, and of their habits or distribution I have obtained no information. ? ? MUSTELA AMERICANA, T u r t o n. Sable. While on the Cascade mountains I saw among the Indians a few skins of the size of that of the ermine, but without the black tip to their tail and of a cream yellow color. They were used as ornaments, and in trade, and valued very highly. They were said to be obtained only on the mountains. LUTRA CALIFORNIA, Gray. California Otter. BAIED, Gen. Rep. Mammals, 1857, 187. The otter is abundant in every stream in the Territory, numbers living even at Cape Disappointment at the junction of the salt with the fresh water, where they have formed paths leading up the almost perpendicular rock to the dense thickets above, and quite inaccessible to the hunter. Though I have often watched for them, I never saw one, so nocturnal and cautious are they in their habits. ENHYDRA MARINA, Fleming. Sea Otter. BAIRD, Gen. Rep. Mammals, 1857,189. The sea otter is not found near the mouth of the Columbia river, as it prefers rocky coasts and islands. From the "Quinailt," a small river emptying about 50 miles north, to Cape Flattery, numbers of skins are brought, for which the Indians, obtain an extravagant price — in goods, often as much as $30 to $40. MEPHITIS OCCIDENTALS, Baird. California Skunk. ? Mephitis mesomelas, ST. HILAIRE, Voy. de la Venus, Zoologie, I, 1855, 133 ; plate. Mephitis occidentalis, BAIRD, Gen. Rep. Mammals, 1857, 194. SP. CH. — Size of a cat. Tail vertebrae two-thirds the length of head and body. Bony palate with small narrow emargina- tioii in the middle of its posterior edge. Color black, with a white nuchal patch, bifurcating behind and reaching to the tail, which is entirely black. ZOOLOGY — MAMMALS. 77 Skunks are very common in the country west of the Cascade mountains, frequenting the borders of woods and settlements. I have often seen them both alive and dead, and all appeared to be of the common eastern species. The commonest markings were black, with a narrow white stripe running back from each shoulder. To show the persistence of the smell, I will mention that wishing to obtain a skull, I took a stick and tried to separate it from what was then only a mass of fur and bones, the animal having been dead about a year, but such an overpowering odor arose that I was glad to retreat without the specimen. I afterwards got one in California, where, being exposed to the sun, the scent had almost entirely left the dried carcass. MEPHITIS BICOLOE. Little Striped Skunk. Mephitis bicolor, J. E. GRAY, Charlesworth 's Mag. N. PI. I, 1837, 581. BAIRD, Gen. Rep. Mammals, 1857, 197. Mephitis zorilla, LICHTENSTEIN, Ueber Mephitis, Abh. Akad. Wiss. Berlin, for 1836, (1838,) 281 ; tab. ii, f. 2. AUD. & BACH N. Am. Quad. III., 1854, 276, (not figured.) Sp. CH. — Smallest of North American species. Tail vertebrae, less than half the body ; with the hairs not much more than half. Black, with broad white patch on forehead, and crescent before each ear; four parallel dorsal stripes interrupted and broken behind ; a shorter siripe on side of belly, running tnto a posterior transverse crescent, which are all white. Tail black throughout, to base of hairs, except a pure white pencil at the end. This little skunk is abundant in Santa Clara valley, south of San Francisco. They are commonly known by the name of pole cat, to distinguish them from the larger species of skunk. The peculiar smell seems somewhat less strong than in that species, but in habits they much resemble it, being very destructive to poultry and eggs, which their smaller size enables them to get at easily by entering the buildings at night. As an offset to this mischief they probably do much good by destroying the still more destructive " ground squirrels " of California, as I attempted to prove to the farmers. They are exactly suited in size for pursuing the squirrels into their holes, though I never heard that they had been seen doing so. Being nocturnal and able to see in the dark, they can take them also at a disadvantage — while they are asleep. The one I obtained I poisoned with strychnine placed on meat in a hen house, which they were in the habit of frequenting nightly. They also often came to a butcher's shop to steal meat and feed on the offal thrown away from it. The eyeballs are excessively prominent, and shine after death with a fiery glare. The pupil is circular, and was much dilated, probably by the strychnine — length 5£ inches ; tail 4 ; iris black ; nose flesh color. TAXIDEA AMEKICANA, Waterh. Badger. BAIRD, Gen. . Mammals, 1857, 302. The American badger is very abundant in the plain country east of the Cascade mountains, its burrows perforating the ground thickly in many places to the great danger of both horses and riders. Yet our party never met with but two badgers by daylight, one of which I obtained. This, by the recommendation of some of the hunters, was cooked, but though some could eat it, the strong "doggy" flavor disgusted me, not to mention its extraordinary toughness and leanness. It is unknown west of the Cascade mountains, though in California a species is said to be found. 78 U. 8. P. R. R EXP. AND SURVEYS 47TH PARALLEL. PROCYON HERNANDEZII, Wagler. Black Footed Raccoon. BAIRD, Gen. Rep. Mammals, 1857, 212. The raccoon is not an abundant animal in any part of the Territory. I have but rarely seen their peculiar foot tracks in the mud, and never saw the animal itself in the woods. The skins are not often seen among the Indians. I had, however, an opportunity of observing a tame one at Portland, Oregon, which, as well as one I afterwards saw in California, had precisely the same habits, impatient cry, and sagacious inquisitiveness, as one which I once kept for many months, and allowed to have perfect liberty. The colors, size, and proportions also showed no appreciable differences. Though this animal has a reputed fondness for oysters, I never saw any signs of its visiting the extensive beds at Shoalwater bay, though it sometimes walked along the banks of creeks emptying into the bay. URSUS AMERICANUS, Pallas. Black Bear. RAIRD, Gen. Rep. Mammals, 1857, 225. The common black bear of the United States is quite abundant in the wooded portions of the Territory, where it is found varying much in color, from which circumstance some authors have supposed that there was more than one species ; I knew, however, of an instance of a black fe male being killed with a number of cubs, all differing in color. One of them, which I saw, was of a light yellowish hue. The color, then, does not even indicate a different race, as it varies in the young of one litter. I have seen bears at a distance, but never got near one, which it is almost impossible to do without dogs, in the dense forests and thickets that they frequent. It is said that before lying down they always walk some distance with the wind, so that anything following their track must necessarily approach to windward and thus give them a chance to escape. From the abundance of " signs" in almost every thicket, and the quantities of berries devoured by them, they seem to be extremely common, and their food must be almost entirely vegetable. I have seen in low springy grounds a kind of "skunk cabbage" torn up by them and the leaf stalks devoured. They sometimes also take pigs and other small stock from the farmer, and devour the dead salmon on river banks in spring and fall. They are almost always fat, unlike their more carnivorous relatives. Several different shrubs are called "Bear berry"* and "Bear wood," from their fondness for the fruit, which is, I believe, in every instance uneatable by man. URSUS HORIBILIS, 0 r d . Grizzly Bear. BAIRD, Gen. Rep. Mammals, 1857, 219. The " Grizzly" is not found in the western wooded regions, nor, I believe, anywhere west of the Rocky mountains in this Territory. PHOCA. Seal. Seals frequent the bays and rivers of the Territory in great numbers, ascending the Columbia * Jjrbutut Uva-Ursi; Xylosteum involucratum ; Rhamnus Purshianus. ZOOLOGY — MAMMALS. 79 to the Dalles, and the smaller streams almost to their heads, probably in pursuit of salmon. As they always sink, when shot in deep water, I never obtained a specimen. Many are killed by the settlers for their oil, and the Indians sometimes have a hunt for them, killing them while asleep on sand bars in the bays, but I never was present on ove of these occasions in time to secure a skin, as they roast the animal with its skin on. SCIURUS RICHARDSONII, Bach. Richardson's Squirrel. Sciurus richardsonii, BACHMAN, Pr. Zool. Soc. Lond. VI, 1838, 100. AUD. & BACH. N. Am. Quad. I, 1849, 41. BAIRD, Gen. Rep. Mammals, 1857, 273. Sp. CH. — Size larger tnan the Hudson's Bay squirrel. Ears with long hairs, presenting the appearance of tufts. Tail shorter than the body. Under surface of feet hairy from heel to metatarsals ; then nearly naked. Above, reddish brown, varied with annulations of black, lighter on the sides ; beneath, dull white ; a dark line separating colors of sides from belly. Tail bushy, sub-cylindrical, dark reddish brown in the centre, entirely of a pure glossy black at tip. The hairs all long and coarse. Hairs on the tail generally, (except at tip,) glossy black beyond the rufous portion, and more or less tipped with paler rusty. One specimen of this species (No. 10) was obtained on the Spokane river, October 30, 1853. SCIURUS DOUGLASSII, Bach. Oregon Red Squirrel. Sciurus douglassii, (" GRAT,")' BACHMAV, Pr. Zool. Soc. Lond.

Zoology of the Sulphur, 1844, 33 ; pi. xii, fig. 2. Sciurus suckleyi, BAIRD, Proc. Acad. Nat. Sc. Phila. VII, April, 1855, 333. Size that of Sciurus hudsonius, or a little larger. Ears well tufted ; tail shorter than the body, scarcely flattened. Soles naked in the centre. Above dull rusty, and black, mixed ; the latter quite predominant ; beneath, clear bright buff, without mixture of dark or annulated hairs. A dark stripe on the sides. Tail dull chestnut centrally, darker above ; then black and margined all round with rusty white. Hairs at tip of tail entirely black, except at their extremity. More northern specimens in winter have the soles densely hairy to the toes, the fur much fuller and softer, the under parts with dusky annulations, the general hue grayer. Size about that of S. hudsonius, or a little larger. Head short, broad. Whiskers longer than the head ; black. Thumb, a mere callosity ; ringers well developed, the central two longest, and nearly equal ; the inner rather longer than the outer ; claws large, compressed, and much curved ; palms naked. On the hind feet the inner toe is shortest, reaching only to the base of the claw of the outer, which comes next in size ; the fjurth is longest, the third and second little shorter. Claws all large and much curved. In summer the soles are naked, except along the edges and the extreme heel ; in other words, there is a narrow central line of naked skin from near the heel ; they are more hairy in winter. The ears are moderate, with short close hairs on their concavity ; the back of the ear is covered with long hairs, those near the upper margin longest, and projecting beyond nearly five lines in some specimens ; these tufts are nearly black. The tail is small, shorter than the body, moderately flattened ; the hairs rather short, and, as on the rest of the body, coarse and stiff. The little Pine Squirrel I found quite abundant in all the wooded parts of the Territory on both sides of the Cascade mountains, and obtained specimens from very distant localities which seemed to agree closely in habits, cries, and colors. They have the same loud and petulant chatter as the eastern species, and descend, fearlessly, to within a few feet of every intruder, scolding and showing their anger in various ways. In the mild climate, west of the Cascade mountains, they do not hybernate, but as they are found also on the summits of these moun tains, they probably there retire for winter, to hollow trees, and live on their hoarded stock of provisions. In summer they inhabit nests of leaves and sticks built among branches and vines. They do not seem to be troublesome to the farmer, as they live on the pine nuts, acorns and hazel nuts abundant in the woods. Probably if Indian corn was a common crop they would not be long in discovering its valuable properties. 80 U. S. P. R R EXP. AND SURVEYS— 47TH PARALLEL. The only difference in the color of the male and female seems to be a deeper hue of the orange colored under parts of the latter. Length from nose to tip of tail, 14 inches. PTEROMYS OREGONENSIS, Bach. Columbia River Flying Squirrel. Pteramys vregmensis, BACHMAV, Jour. Acad. Nat. Sc. Phila. VIII, 1839, 101.— IB. in Townsend's Narrative, 1839. AUD. & BACH. N. Am. Quod. I, 1849, 133 ; plate x BAIRD, Gen. Rep. Mammals, 1857, 290. SP. CH. Much larger than Pleromys volucella. Tail, with hairs, longer than the body alone ; shorter than head and body. Plying membrane very broad, its antero-external corner exhibiting a conspicuous angle. Color above yellowish brown, beneath dull white ; the hairs plumbeous at base. Tail becoming more plumbeous towards the tip. Length, 7 inches ; tail with hairs, 65 ; hind foot, 1£ inches. The only specimens I ever saw were obtained in August, near the foot of Mount St. Helens. In turning over a log, a nest was found under it containing four young, still blind. The mother in attempting to escape was killed by a pistol ball, and was lost before I could see it. It was much larger than the P. volucella of the eastern States. I never heard of one having been seen in the country nearer the coast, and think it is confined to the mountains. TAMIAS TOWNSENDII. Townsend's Striped Squirrel. Tamias townsendii, BACHMAN, Jour. Phila. Acad. Nat. Sc. Phila. VIII, i, 1839, 68. — IB. in Townsend's Narrative, 1839, 321. AUD. & BACH. N. Am. Quad. 1, 1849, 159 ; pi. xx. BAIRD, Gen. Rep. Mammals, 1857, 301. Tamias cooperii, BAIRD, Pr. Ac. Nat. Sc. Phila. VII, April, 1855, 334. SP. CH — Larger than T. striatus. Tail, with hairs, nearly or quite as long as the body. Sides of head striped. Above and on the sides rufous brown, with five dark stripes reaching to the tail, the intervals between which are scarcely or but seldom paler than the ground color ; beneath, dull white. Ears dusky brown, hoary posteriorly. Tail bright chestnut beneath, margined with ashy white, within which is a band of black. Length 5 to 6 inches. Hind foot 1.40 to 1.50. Varies in rather paler colors, ash-colored interspaces, and sometimes the back with black hairs interspersed, so as to obscure or nearly conceal the dorsal stripes The ground squirrel, or " chipmunk," inhabiting the neighborhood of the coast in Washington Territory, resembles closely in its habits that common on the Atlantic border. It differs, however, considerably in colors, and has not the shrill cry of the eastern species. About the first of April it emerges from its winter nest and soon after great numbers are seen where none appeared before. In summer they will often sit on some prominent stump or rock, and make a shrill barking noise for hours together, answering each other from distant parts of the woods. They become very mischievous in the garden, being especially fond of peas either green or ripe, for which they will come from their burrows several rods distant, as I have observed from the scattered pea-vines growing along the path where they have dropped the seed from their overloaded cheek- pouches. In November they retire to their burrows to sleep through the long rainy season, though it is probable that in the warm weather, often occurring in the winter of this coast, they come out to breathe the fresh air from time to time. The ground squirrels obtained on the summit of the Cascade mountains differ in some respects from those near the coast. As I observed these animals in abundance in all the wooded regions, and saw no marked differences in their appearance or habits, I supposed all to be of one species, varying slightly in size and colors from differences of climate, which, between the perpetual ZOOLOGY MAMMALS. 81 spring of the western regions and the edges of perpetual snow on the mountains, would he equal to many degrees of latitude on the eastern coast, and judging from analogous facts should have an influence on these characters. Their principal food on the eastern slopes of the Cascade mountains was the pine nut, and during September I observed them very busy extracting these from the still hanging cones, ascending the trees to a considerable height, though at other times they rarely leave the ground. I find it stated in my notes that they had there a similar shrill cry to that of the eastern species.

VII, 1855, 334.— IB. Gen. Rep. Mammals, 1857, 307. Sp. CH. — Size of the cat squirrel, S. cinereus. Ears large, prominent. Tail more than two-thirds as long as the body. Above mixed black, yellowish brown, and brown in indistinct mottlings ; beneath, pale yellowish brown, Sides of head and neck, hoary yellowish, more or less lined with black, a more distinct stripe of the same, from behind the ears on each side, extending above the shoulders to the middle of the body. Ears black on their inner face. Dorsal space between the stripes scarcely darker than the rest of the back. Length, 9 to 11 inches ; tail, with hairs, 7 to 9. Hind feet, 2 to 2.30 inches. The marmot squirrel, called ground squirrel in Santa Clara valley, is found in incredible numbers in all the level or low land southward from San Francisco bay. It is one of the greatest pests to the farmer, destroying immense quantities of grain, and in spite of poisoning, drowning-out, shooting, and trapping, seems rather to increase than diminish in numbers. In travelling along the public road in a s age coach they are to be seen on every side, sitting boldly at the mouth of their burrow as the vehicle passes within a few yards, as if defying danger, those furthest off raised on their hind legs to have a better view, and looking like short gray stumps, so motionless do they sit. If one is fired at it disappears as if by magic, and even if you are fortunate enough to shoot it at a distance from any burrow, it will spend its last breath in the attempt to reach one, so that unless its head is shot off by a rifle ball, the chance of getting it is very small. But they may often be recovered by feeling for them with the ramrod when dead near the mouth of the burrow. They are very fine eating, and formerly sold well in San Francisco market, but since strych nine has been used to kill them, no one will buy them for fear of being poisoned. When startled and about to run into their burrow, they make a shrill screaming cry, somewhat like that of our eastern striped squirrel, when frightened. It is said that these animals will often destroy 30 or 40 acres of wheat in a field, cutting off the heads and leaving none behind in their progress. Magazines of theirs are found in digging wells, thirty feet below the surface, and from the large pile of earth thrown out at the mouth of their burrows they must be very extensive. There are commonly two or three entrances near together, which probably communicate, and in many places these holes occur every few yards, so that there may be several hundred in an acre, and many appear to inhabit one burrow. They are very hard to drive away from their homes, remaining in the fenced gardens and about houses until they are killed. Being entirely diurnal in habits, and appearing most abundantly in the hottest part of the day, they are exposed to many enemies besides man, and 11 Q 82 U. S. P. K. E. EXP. AND SURVEYS 47TH PARALLEL. it is wonderful how they continue so numerous. Except in the very lowest ground, overflowed by tides, there is no part of Santa Clara valley where they cannot be seen at any time, scampering over the ground and watching at their burrows. Where it is practicable, the farmers combine in the commencement of the rainy season and build dams in the water courses, so as to overflow the land and drown out the squirrels.

I shot a single specimen of a striped squirrel, near the eastern base of Mount Adams, in August, 1853, where it was in company with the common Tamias, which swarms in those pine forests. Its large size and something peculiar in its general appearance induced me to shoot it, and I have now no doubt that it was this animal. I unfortunately lost the specimen, and did not meet with another. It was excessively fat. APLODONTIA LEPORINA, Rich. Sewellel. BAIRD, Gen. Rep. Mammals, 1857, 353. The " Sewellel" of Lewis & Clark, appears to be an abundant animal in some districts west of the Cascade mountains, but from various causes I never could obtain a specimen. At the time of their visit to the country the Indians used the skins as clothing, and as it required a large number of skins to make an ordinary sized blanket, the numbers of the animals caught must have been great. It was caught by stone fall-traps, but with what bait I do not know, probably some root. The Indians assured me that none were found nearer to the coast than the Cowlitz valley, but as they have been obtained at Astoria, the statement was not altogether correct. They seem to prefer the soft alluvial river bottoms, where they are said to burrow, and probably thus follow down the Columbia. Now they are rarely caught by the Indians, as their skins are not bought by the Hudson's Bay Company, except when passed off on a " green" clerk as muskrat skins. Of their habits I could learn little. An old Indian hunter, who is now a shepherd in the employ of Dr. Tolmie at Puget's Sound, told him that he had frequently seen them running over the snow in the Nisqually valley, so that they probably do not hybernate. A young man who had kept school at Astoria told me that the children sometimes caught them about the school house, where they burrowed, and that they could be caught by running after them, as they did not run fast. When taken they did not offer to bite, and ate vegetable food readily. The specimen sent from there was found drowned in a tanner's vat. CASTOR CANADENSIS, Kuhl. Beaver. BAIRD, Gen. Rep. Mammals, 1857, 355 The beaver is abundant in many of the streams of the wooded regions, and is said to have become more so since trapping has become unprofitable. Near the coast they live in the close vicinity of farms, but are very rarely seen. I have often watched at evening, hoping to see them at work, but they never appeared. The only one I ever obtained was while descending the Chehalis river, where, about sunrise, one of the Indians saw it swimming close to the bank, with ZOOLOGY MAMMALS. 83 only its nose above water. He shot it, and on getting it into the canoe it proved to he a very large one, extremely fat. We soon after landed, skinned, and cooked it, the Indians con sidering it a great delicacy, but, though hungry, I thought it barely eatable. A fishy flavor pervaded every part of it, and it was very tough. The Indians were much disappointed at my keeping the tail with the skin, as they are very fond of it ; but the taste that can fancy such a compound of gristle and fish oil must be acquired by long trials. Dimensions of specimen. Head and body, 3 feet long. Tail, one foot long, 4f inches wide, 3^ inches round at root. Eye black. Skull preserved. Female. In California I saw a much larger skull of a beaver from the San Joaquin, but resembling this exactly in other respects. It is in the collection of the California Academy of Sciences.

Quad. II, 1851, 251. Jaculus hudsonius, BAIRD, Gen. Rep. Mammals, 1857, 430. SP. CH. — Above, light yellowish brown, lined finely with black ; entire sides yellowish rusty, sharply defined against the colors of the back and belly. Beneath, pure white ; feet and under surface of tail, whitish. Body measuring 2.75 to 3.50 inches ; tail, 4.50 to 6. 00 inches ; hind feet, 1.10 to 1.30 inches. A single specimen of this species was collected in Washington Territory. HESPEROMYS GAMBELII, Baird. Western Deer Mouse. BAIRD, Gen. Rep. Mammals, 1857, 464. SP. CH. — Very similar to H. leucopus in size and proportions. Ears larger, feet shorter. Tail generally a little less than head and hody. Above, yellowish brown, much mixed with dusky, but without a distinct broad wash of darker on the back. Entire exterior of fore leg below the shoulder, white. This wood mouse is common in the forest regions. Near the coast, where the common mouse has not been introduced, it takes up its residence in houses, and is quite as mischievous as the latter. It has, however, one habit not observed in that species — that of making stores of provi sions in any place it finds suitable, though with little apparent foresight. It is not uncommon in the morning to find a handful of rice, &c., in your boots, and often it has been brought a considerable distance during the night, showing that several mice must have been industriously employed in collecting it. They will also make a storehouse of your bed while you are asleep, piling the grain about your feet, but never biting or awaking you. It is strange that though you may empty out their stores every day, they are sure to make another deposit each night for weeks. HESPEROMYS AUSTERUS, Baird. Black Mouse. Hesperomys auslerus, BAIRD, Pr. A. N. Sc. Phila. VII, April, 1855, 336.— IB. Gen. Rep. Mammals, 1857, 466. SP. CH. — Fur full and soft; rather smaller than H. leucopus; feet larger in proportion. Young, dark slaty plumbeous. Adult, dark sooty brown, slightly pervaded by yellowish brown on the cheeks and lower part of the sides, the dusky of the sides extending even in the adult to the wrist ; both feet above, and under parts, white ; tail well haired, as long as head and body, lower half white. I obtained a specimen of this mouse at the camp August 11, on top of the Cascade mountains. 84 U. S. P. R. R. EXP. AND SURVEYS — 47TH PARALLEL. This drowned itself in a pail of water. At this time there was ice formed every night at our camp. The second specimen I obtained was also found drowned in a pail of water at our camp on the great Spokan Plain, October 31, 1853. There being no trees within many miles of us, this species probably lives entirely among the grass of the prairies. As we had snow and severe frosts at that time, it probably remains active all winter. HESPEKOMYS BOYLII, Baird. Long Tailed Mouse. BAIRD, Gen. Rep. Mammals, 1857, 471. Sp. CH. — Body stout. Ears very large, almost naked. Tail stout, considerably longer than head and body, with long hairs at the end, and 32 vertebrae. Above, mixed brown and yellowish brown ; paler on the sides. Outside of fore leg colored to the wrist. One specimen was collected at Shoalwater Bay, Washington Territory. HESPEROMYS CALIFORNICUS. Mus californicus, GAMBLE, Pr. A. N. Sc. Phila. IV, August, 1848, 78, (Monterey.) Hesperomys californicus, BAIRD, Gen. Rep. Mammals, 1857, 478. Sp. CH. — Very large. Size of a third grown rat. Ears very long, angular. Tail rather longer than body. Color above, sooty brown, passing on the sides to fulvous. Under parts white, tinged with fulvous and ashy. Feet white. Tail brown, a littler darker on the dorsal line. Soles entirely naked. In a trap set for wood rats I caught, one night, a mouse, which though very similar in proportions and appearance to the rat, proved to be quite different, and even of another genus. I afterwards got two more of them from an old rat's nest that I burned down. There were three or four in it, and they remained until there was scarcely a stick unburnt before deserting it. N$ rats were in this nest, and I have always found that not more than one or two of those surrounding a tree were inhabited by them, the rest having a dilapidated appearance, and being left to their smaller relatives, these wood mice and field mice. Of the habits of this wood mouse I know nothing further. They probably much resemble those of the numerous species found in the United States. I may remark here that up to my departure from California, on December 1, I saw no signs of hybernation of any of the small rodentia, except a striped squirrel, which I only saw out once, and having watched often afterward, concluded it had retired for the winter. There was then very little frost. Dimensions. — Nose to tail, 4| inches. Tail, 4f . Hind foot, 1 inch. Fore foot to wrist, £ inch. Ear, f inch long, £ wide. NEOTOMA FUSCIPES, Cooper, Mss. BAIRD, Gen. Rep. Mammals, 1857, 495. (From Mss. of J. G. Cooper.) Sp. CH. — Larger than the house rat (Mus decumanus). Tail nearly as long as the head and body, compressed at tip Color above, yellowish rusty brown, lined with black. Beneath, soiled white. Hands and toes of hind feet white ; the upper part of metatarsus dusky. Tail uniformly dusky all round. I found the wood rat of California extremely common in all those parts of Santa Clara valley more or less covered with groves of oak and different shrubs. Almost every tree, either of the evergreen or deciduous species of oak, had from one to six of their buildings under it. These are built of short sticks, chips, and sometimes bones, piled with such skill as to shed rain — the upper layers projecting downwards. Their form is conical, and height generally from four to five feet, having about six entrances at the ground, and burrows extending beneath it as a retreat ZOOLOGY MAMMALS. 85 in case their house is demolished.* I tore down several, hut could not hy that means ohtain any of the rats, though, from the warmth of their nest, they had evidently just left it. This nest is composed of fine grass, bark, and leaves, is about large enough to fill a hat, and placed near the middle of the building, about a foot above the ground. By means of galleries and openings like windows in the sides of the pile, they watch the approach of danger from their nest without being seen. I succeeded in shooting several rats at last, by burning down their houses, and watching for them as they came out. They would stay till the last moment — often until they were much singed. If another nest was near, they ran for it ; if not, ascended the nearest tree, and sat stupidly gazing at the destruction of their home, dazzled by the blaze. I also caught some in a steel trap, baited with biscuit, of which they seemed very fond. They are mostly nocturnal in habits, but sometimes come out in the daytime, when all around is quiet, and then fall a prey to the numerous hawks that are watching for them and the squirrels. This wood rat lays up large stores of acorns, &c., in hollow trees, and has been known to kill, and carry to this retreat, a whole broad of chickens. It is, however, not very troublesome to the farmer, and never makes its residence in houses. All that I obtained from their nests were males, and in no nest did I find more than two together. The females probably have a nest in hollow trees, where they produce their young, as I was told that they were sometimes driven out with the young clinging to them, as do those of the wood mouse. A hunter told me that when encamped near these rats' nests, he once had a large quantity of ship biscuit stolen by them, and for a long time he suspected the Indians of the theft, until he thought of searching the premises of his four-legged neighbors, where he found the whole of the plunder carefully piled away. I found these rats quite active up to the 1st of December, and their hybernation is short, if any, in the lower valleys.

NEOTOMA OCCIDENTALS, Cooper. Bush-tailed Rat. Neotoma occidentalis, (Co iper MSS.,) BAIRD, Pr. A. N. Sc. Phila. VII, April, 1855, 335. BAIRD, Gen. Rep. Mammals, 1857, 496. Neotoma drummondii, AUD. & BACH., N. Am. Quad. I, 1849, 223 ; pi. xxix. Sp. CH. — Size of Norway rat. Fur harsh. Tail densely hairy, the vertebras as long or longer than the body, exclusive of the head. Color above, broadly grayish lead color, the basal wool but little lighter. Posterior third of soles furred. Body above, brownish plumbeous, with a slight mixture of yellowish brown. Under parts of body and tail, with feet, bluish white. The "wood rat," as it is called near the coast, inhabits the wooded regions west of the Cascade mountains, but is more abundant in some places than others. I did not hear of it at Puget's Sound, where I inquired for it. At the Cascades of the Columbia I was first told of such an animal, and am inclined to think it prefers the mountains rather than a level country, like that at the Sound and Vancouver. At Shoalwater bay, in July, 1854, I first obtained a specimen. Having occasion to sleep in a log house, at the foot of some high hills, the owner told me that the wood rats were very troublesome to him, eating everything vege table they could get at, and carrying off articles that they could not use. The house being uninhabited most of the time, we found on entering that they had made a nest on the bedstead, * An Australian rat of a different genus is described as building houses of the same kind. — ( Hapalolis conditor, Gould ) 86 U. S. P. K. R. EXP. AND SURVEYS — 47TH PARALLEL. and collected a pile of fresh elder leaves, grass, and other food, together with a pair of broken iron hinges, brushes, bones, and other useless articles. We saw none until night, when they began to come in, and one climbed up to the bed, where,, finding strangers in possession, he retired behind a rough board with which the joints of the logs were covered inside. Here he kept up a curious ticking sound for some time as if to show his anger at our intrusion. Having got a light, I watched him through a crack, but could not see how he made the " mysterious rapping." I then sharpened a stick and speared him with it as he sat. Afterwards a family of these rats took up their residence in a house where I lived. They had much the same mischievous habits as the common rat, but were less cunning. I could only catch them in traps by placing these in their way, as they refused cheese, bread, and other baits. We finally succeeded in killing the whole family of seven, which were all full grown. One poisoned itself by eating part of a bird skin preserved with arsenic. We afterwards found the nest made of oakum among a pile of flour barrels. A strong and disagreeable smell was perceptible about it. I never heard these rats squeal or make any sound when frightened or wounded. The largest specimen measured as follows: Male, head and body, 10 inches. Tail, 8£. Fore leg, 4f ; hind leg, 5£ inches. Ear, 1 inch long, 1^ wide. Female smaller. ARVICOLA TOWNSENDII, Bachman.

Ill, 1853, 209 ; pi. cxliv, fig. 1. BAIRD, Gen. Rep. Mammals, 1857, 527. Sp. CH. — Very large, (head and body 5£ inches.) Ears large ; two-thirds as long as hind foot ; well furred. Tail, including the hairs, rather less than half the head and body ; the tail yertebrse twice the length of hind foot. Thumb claw conspicious. Toes long ; one-third the whole foot.

Tail almost uniformly brown throughout. Feet liver brown. Skull, 1.27 -|- 71, or as 100 : 56. This meadow mouse is abundant on the meadows of Shoalwater bay, where it appears to have much the same habits as the species common in the Atlantic States. It forms summer nests of grass on the surface of the ground, commonly close to a root or log. Though I have frequently examined these, I never found young in them. It also makes galleries or paths through the grass, cutting off closely every stalk that stands in the way. During the annual floods which cover these meadows, great numbers of mice come out on the higher grounds, and thousands are doubtlessly drowned, which assists their many animated enemies in keeping down the numbers of a prolific and destructive animal.

The muskrat appears to "be rather scarce in the western portions of the Territory, where I never saw any signs of their existence. I have been told, however, by credible persons that they were sometimes found, though scarce. I can only account for this scarcity of an animal so abundant even in the thickly settled portions of the Atlantic States, by supposing that the beaver, where abundant, keeps them away. We find many instances of animals of similar habits thus holding possession by the right of the strongest; of which I will only cite one example among rodentia, that of the Norway rat, which has so far dispossessed every native species in countries where it has been introduced. LEPUS WASHINGTONI!, Baird. Red Hare Lepus washingtonii, BAIRD, Pr. A. N. Sc. Phil. VII, April, 1855, 333.— IB. Gen. Rep. Mammals, 1857, 583. Ears shorter than the head ; hind feet much longer than the head. Size about that of L. sylvaticus, or a little larger. Fur very soft and full on the body and beneath the feet. Tail very short. Back, sides, and throat reddish brown ; the former with many glossy black hairs. Tail lead color above, rusty white beneath. Abdomen pure white. Ears black on the posterior margin and tip of their inner surface ; the rest of this surface pale reddish brown, except on the exterior band . This small species of hare seems peculiar to the forest region west of the Cascade mountains. I have never found it common, however, at any point except about Fort Vancouver or the Columbia, where, on account of the dense bushes they frequented, I found it very difficult to shoot them. They also occur on the borders of prairies in other western parts of the Territory, but are nowhere so abundant as the little Virginian hare is in the rural districts of the middle States. I observed them in winter, when the ground was covered with snow, and there was then no change in their color. A species with black ears and tail is said to be found at the Cascades of the Columbia. During our journey east of the Cascade mountains we saw scarcely any hares, and the Indians told us that some disease had killed nearly all of them. Dimensions of specimen : length, 17 inches. LEPUS TROWBBIDGII, Baird. Lepus trowbridgii, BAIRD, Pr. A. N. Sc. Phila. VII. April 1855, 333.— IB. Gen Rep. Mammals, 1857, 608. Sp. CH. — Size small, less than that of L. auduboni. Head small. Ears about equal to it in length. Tail very short, almost rudimentary ; hind feet very short, well furred, considerably shorter than the head. Color above, yellowish brown and dark brown; beneath, plumbeous gray. Sides not conspicuously different from the back, but paler. Back of neck pale rusty. Ears grayish and black on the external band ; ashy gray elsewhere, with little indication of darker margin or tip. The little hare, or " rabbit," of California, abounds in bushy, dry ground in Santa Clara Valley, and has much the same habits and appearance as the common Virginia hare in the middle States. It sits during day under the shelter of some thicket, and about dusk ventures out cautiously to feed. If started, it runs a short distance only, seeking the nearest concealment — unlike the large species, which trust more to their speed for escape. It is easy to shoot numbers of these little animals, either early in the morning or evening, by watching near their resorts. I have never observed them about wet grounds, and it is said that they do not frequent the hills, like the large hares, but keep entirely in the level prairies. 88 U. S. P. R. R. EXP.

I was told of another kind of small rabbit of a bluish tint, shorter ears, and which burrowed in the ground, but I could not get any. The accounts of it were also conflicting. CERVUS CANADENSIS, Erxl. Elk. BAIRD, Gen. Rep. Mammals, 1857, 537. The elk is abundant in the dense forests of the Coast Range, and found in less numbers in the other wooded portions of the Territory. It is very wary, and difficult to kill at most times, but is often shot on the small prairies, near the heads of rivers, where it feeds in the evening and early morning. In severe winters, also, when they leave the mountains, and in large herds descend to the warmer prairies along the coast, they are tracked in the snow to their lairs, and shot. Many frequent these prairies every winter, returning in early spring to the mountains. In some places the Indians formerly surrounded the herds, and by gradually narrowing their circle, succeeded in killing many. It is almost useless to hunt them in the forest, where the dense underbrush gives them every advantage over their pursuer. An intelligent farmer, who formerly hunted elk in New York State, told me that he con sidered these a different animal, being much larger, and having larger and differently formed horns. CERVUS COLUMBIANUS, Rich. Black-tailed Deer. Cervus macrotis, var. colwnbianus, RICHARDSON, F. B. Am. I, 1829, 255 ; pi. xx. Cervus columbianus, BAIRD, Gen. Rep. Mammals, 1857, 659. SP. CH. — About the size of C. virginianus, or less. Horns doubly dichotomous, the forks nearly equal. Ears more than half the length of the tail. Gland of the hind leg about one-sixth of the distance between the articulating surfaces of the bone. Tail cylindrical, hairy and white beneath ; almost entirely black above. The under portion of the tip not black. Winter coat with distinct yellowish chestnut annulation on a dark ground. Without white patch on the buttocks. There is a distinct dusky horse-shoe mark on the forehead anterior to the eyes. I have only seen one species of deer in the Territory, and this only west of the Cascade range. It is not abundant, except in a few places, the most remarkable of which is Whitby's island, at the Straits of De Fuca, where extensive and luxuriant prairies support large numbers of them, now, however, becoming scarce under the continual slaughter kept up at all seasons by the settlers. While there, in March, 1855, I saw a great many frequently in open daylight, but more commonly at dusk. The fact observed by Lewis and Clark, that when started they always go away by a succession of jumps, with all four feet striking the ground at once, I have often noticed, but have also seen them trot very leisurely away when they perceived the hunter at some distance off. A mottled, and sometimes entirely white variety, is not uncommon on this island and on the coast. I preserved a perfect specimen of this deer.

These wolves are very abundant in the neighborhood of the sources of the streams flowing into the Columbia from the Cascade, and Blue mountains. In the winter, until March, they come down into the valleys, where they are very destructive to horses, hunting them singly or in packs. They destroy the largest horses by hamstringing them while running. This is their favorite way of hunting. They are about 3 feet high.

Above, dull rusty asd black, mixed ; the latter quite predominant ; beneath, clear bright buff, without mixture of dark or annulated hairs. A dark stripe on the sides. Tail dull chestnut centrally, darker above ; then black and margined all round with rusty white. Hairs at tip of tail entirely black, except at their extremity. More northern specimens in winter lave the soles densely hairy to the toes, the fur much fuller and softer, the under parts with dusky annulations, the general hue grayer. Size about that of S. hudsonius, or a little larger. Head short, broad- Whiskers longer than the head ; black. Thumb, a mere callosity ; fingers well developed, the central two longest and nearly equal ; the inner rather longer than the outer ; claws large, compressed, and much curved ; palms naked. On the hind feet the inner toe is shortest, reaching only to the base of the claw of the outer, which comes next in size ; the fourth is longest, the third and second little shorter. Claws all large and much curved. In summer the soles are naked, except along the edges and the extreme heel ; in other words, there is a narrow central line of naked skin from near the heel ; they are more hairy in winter. The ears are moderate, with short close hairs on their concavity ; the back of the ear is covered with long hairs, those near the upper margin longest, and projecting beyond nearly five lines in some specimens ; these tufts are nearly black. The Lail is small, shorter than the body, moderately flattened ; the hairs rather short, and, as on the rest of the body, coarse and , ,ff. Many specimens of this species were collected at Fort Steilacoom. The food of the present species differs from that of those collected in the Rocky mountains, (/S. richardsonii,) in being confined to the cone seeds of the fur and spruce, whereas in the Rocky mountains the squirrels live on the seeds of the red pine. Both species have the same habits and peculiarities of the red squirrel of the middle States, very familiarly chatting and " scolding" when disturbed by the presence of man, when they become easy prey to the gunner. I have observed them here in mid-winter running about in the woods as actively as in warm weather, and they, therefore, do not become torpid and hybernate.

BAIRD, Gen. Rep. Mammals, 1857, 353. Sp. CH. — Size of muskrat. Tail scarcely appreciable. Color reddish brown. Three specimens collected at Steilacoom — (11, 93, 92.) They are found in considerable numbers on the Cowlitz rivers, as well as in other localities near here. Being about the size of muskrats, their skins were formerly palmed off to the Hudson Bay Company's agents by the Indians as skins of that animal, thereby frequently deceiving the new and inexperienced employes of the company. Mr. Gibbs (who presented me with the specimen sent) has handed me the following notes concerning it : "The specimen I send you was obtained at Seattle, where it was killed in a garden. Its name, in the Nisqually language, is Showt'l, (Shoivhurll, Suckley.) Color gray; hair short and coarse ; legs short; eyes small; tail almost wanting. This animal burrows extensively in the ground. It chiefly frequents spring heads in rich moist places, and is found as far up as the dividing ridge of the Cascade mountains and on both sides of the divide. I noticed their bur rows in 1853 at the top of the main Yakima pass. Near their abodes were small bundles of pome herb or plant cut with nicety and laid out on logs to dry or wilt. The Indians trap them, and value their meat very much as food." The Nisqually Indians formely made garments by sewing together a number of the dried skins of this animal. They are caught generally by traps resembling in action our "figure 4" traps. CASTOR CANADENSIS, Kuhl. Beaver. BAIRD, Gen. Rep. Mammals, 1857, 355. Milk river, Neb. DIPODOMYS PHILLIPII, Gray.

This hare breeds in great numbers on the vast sage plains to the south of Boise river, between it and Snake river. They are said to turn white in the winter.

Ch. see chap. 2, p. 88.] This animal is quite abundant in the vicinity of Puget Sound, and probably extends throughout those portions of Oregon and Washington Territories situated between the Cascade range and the coast. I never saw it east of the Cascades. It is very common near Puget Sound, where I got a half dozen specimens. One, obtained alive at Mticklesnoot prairie, I kept for some time in a box, upon the bottom of which was a quantity of rich black loam. When disturbed it instinctively endeavored to escape by burrowing in the earth of the box, using its long pointed nose as a wedge to pioneer the way. The excavation was performed by its broad stout hands, which, surmounted with their long sharp claws, seemed admirably adapted for the purpose. The fore paws were worked alternately as in swimming, the hind feet acting as propellers. Although the earth in the box was very soft and friable, it was nevertheless a matter of astonishment to see how rapidly the little creature could travel through it. When he slept it was in a sitting posture, with the body curled forward and the neck strongly flexed, so that the nose rested between the hind legs. He thus assumed a ball shape, evidently his usual natural position when asleep. This mole, being subsequently killed, was duly measured, and the measurements recorded in my note book, as follows : No. 85. $ . Length from nose to base of tail 6. 75 Length of tail. 1. 50 From occiput to tip of nose 2. 00 Length of hand, including middle nail 1.10 Extreme reach from longest claw of hind foot to ditto of fore foot 7. 87 Penis concealed in its sheath. Glans flattened. Eyes scarcely apparent before skinning. They live in the more rich and open grounds, making burrows near the surface resembling closely those made by the common garden mole in the Atlantic States. — S. NOTE. — During Dr. Buckley's absence from the United States, chapter 2 of the present section was published. It was found afterwards that many notes and memoranda had been mislaid, or had, from some other cause, escaped insertion. It was therefore determined to join the unpublished material with a number of valuable notes which had been kindly furnished by George Gibbs, esq., and to print the whole, as thus connected, in the present chapter. Care has been taken to avoid useless repetition of any of the matter which appears in chapter 2 ; but, when necessary, a reference is made to the page in the first report, as well as to that of Professor Baird's general report on the mammals of the routes of the different surveys. — S. 108 ZOOLOGY.

Ch. see chap. 2, p. 88 ] The cougar, or, as it is frequently called, "California Lion," is common in Oregon and Washington Territories. They are quite abundant in the mountains of the Klamath. The Indians there sew two skins together, and wear the robe thus formed as a blanket, the tails trailing behind. Two skins of the young panther were obtained by me from a man at Steila- coom. They are marked much like the wild cat, but have a longer tail. The living animals were about the size of weaned kittens. — G. NOTE. — I have several times heard of some large animal of the cat kind said to differ from the cougar. One was reported to have been seen in California by some mining acquaintances I made there. It was described as stouter than the cougar, deep chested, with a dark tawny mane! Lately a very intelligent man, Mr. Samuel Woodward, of Shoalwater bay, W. T.> informed me that he had seen in that neighborhood an animal standing higher upon its legs than a cougar, with erect ears and a short tail. The Indians of the Willamette have a story of some terrible animal inhabiting the woods bordering the Columbia on the south, which is not a cougar. It may be that there are imaginary differences, but the subject deserves investiga tion. Perhaps these animals are straggling specimens of the northern lynx. — G. The cougar is quite abundant in the thickly wooded sections of Washington Territory, near the coast, being especially abundant on some of the heavily timbered river valleys, such as that of the Cowlitz, Chehalis, Nisqually, and others. Near Fort Steilacoom a few are killed every year, occasionally quite near the garrison. There have not, as yet, been any instances in that vicinity of human beings having been attacked by them. They are, however, destructive to young calves and other small animals. They are said to utter shrill screams, and at times loud whistling sounds, at night. Perhaps these, when much heard, proceed from the amatory conflicts and spiteful sanguinary courtships which, it is fair to suppose, exist as much among them as with their cousins, our domestic dependants. I am indebted to Major James Tilton, United States surveyor general of Washington Terri tory, for the present of the finest and most complete skin of this species I have ever seen from the northwest coast. It is now in the collection of the Smithsonian Institution. Townshend speaks of the indication of a second and nearly allied species on the Columbia. His opinion is based upon a peculiar skull and one foot of an animal he there obtained. Perhaps this may have belonged to the "terrible animal" to which Mr. Gibbs alludes. The ZOOLOGY. 109 kitten skins obtained by Mr. Gibbs were got in August; and it is fair to suppose that they were littered in July. The Indians speaking the Nisqually dialect'call this animal swo-iuali. — S. LYNX FASCIATUS, Raf. Western "Wild Cat; Red Cat. Lynx fasciatus, RAF. Am. Month. Mag. II, Nov. 1817, 46. BAIRD, Gen. Rep.

[For specific characters in detail of this species see chap. 2, p. 90.] The western wild cat is abundant in the thickly wooded districts bordering the lower Columbia and Puget Sound. Lewis and Clark, in speaking of this animal, call it the "tiger cat," and say that it is much larger than that of the States, with much finerTfur. They remark that the Indians made robes out of four skins. The name of this animal in Yakima (a dialect of the Walla-Walla language) is Pitzeni. and in Nisqually Pish-pish. The older settlers say that there are two kinds of wild cat in the neigh- borhorhood of Puget Sound — one being the species now under consideration, the other called the brindled cat. I saw a specimen of the L. fasciatus at Olympia in 1856. It was about twice the size of the common wild cat. Tail short, ears black, with gray spots upon""them like "thumb marks.7' The Skokomish Indians call it Clitbuk. The Indians say that there^are two cats besides the cougar, thus corroborating the statements of the settlers. A very intelligent settler, a keen hunter, and an observing man — Judge Ford, of the Chehalis river — says that there is a third kind, which is spotted black and white, and is much more slender than the common wild cat of the country. — G. The barred lynx is a very abundant species in the thickly wooded districts of Washington Territory; so much so that I obtained a half dozen specimens during the last year I resided there. One of these (a female) was shot in a barnyard near Fort Steilacoom. It and a com panion were standing near some calves, whisking their tails, and apparently bent upon mischief. It is not often that they attempt to take such large prey; but usually they content themselves with young pigs, or other small delicacies that may fall in their way near the settler's home. When not depending upon what can be stolen from the farmer or shepherd, they subsist upon younp; fawns, rabbits, ruffed grouse, small birds, squirrels, &c. There may be two kinds of wild cats in the Territory north of the Columbia, the present species and the Hudson Bay lynx. The latter Townshend says inhabits Oregon. The Indians about Puget Sound, when asked, always say that there are two lynxes or wild cats. One of these they call Bellopes; but the Bellopes is the raccoon, (Procyon liernandezii.} Undoubtedly these natives have not studied comparative anatomy very extensively. After removing the Bellopes and asking how many other kinds of wild cats exist in their country, they answer only one, pointing to a skin of the red cat of the present article. The kind spoken of by Mr. Gibbs as having been seen by Judge Ford may perhaps be a partially grown cougar, which we know are spotted when young; or it may be a young individual of the Hudson Bay lynx, or even a new and undescribed species. I have friends on the lookout for the animal, so that, if at all abundant, I shall probably ere long receive a specimen. The Indians eat the red lynx whenever obtained. Upon their recommendation I tried a steak broiled, but have no hesitation is pronouncing the creature not good. A prominent mark of this species is the gray "thumb mark" on the ears. 110 ZOOLOGY.

NOTE. — For several skins of this lynx, and for many other scientific as well as personal favors, I am indebted to my friend the popular and highly esteemed secretary of Washington Territory, his excellency the Hon. Charles H. Mason. CANIS OCCIDENTALS, var. GRISEO-ALBUS. Gray Wolf. BAIRD, Gen. Rep. Mammals, 1857, 104. SP. CH — Color of various shades, from gray to white Some skins are much tinged with brown. The Gray Wolf occurs on the Clatsop Plains, near the mouth of the Columbia, and also upon the Nisqually Plains, Puget Sound. It attains a very large size, and is too much for any single dog. It is called by the Chinooks Ileakhum, and is the Spilyer of the Yakimas. A black wolf was seen by me in the mountains between Scott's and Shasta valleys, in northern California, in 1851. Several were together. A "black wolf," perhaps the same, perhaps the C. nubilus, or "dusky wolf," is found on the Nisqually Plains, Puget Sound. Some skins are grizzled. — G. Owing to the variety in the shades and colors of the wolves of Oregon, the settlers at the Dalles, mistaking varieties for species or "kinds," consider that there are more species than the examination of many skins in the Smithsonian collection seems to justify. There is considerable difference of opinion among the white inhabitants as to the number of ZOOLOGY. Ill these species. Some make four species : two large or mountain wolves, and two small or coyotes. The mountain kinds are the black (probably Canis nubilus) and the red, (most likely the Canis occidentalis, which frequently is tinged with ferruginous.) Whether the "Hoc* wolves" are Hack, I consider doubtful. Settlers, however, have positively assured me that they have seen wolves "perfectly Hack." Frequently the black hairs on the back of the Canis occidentalis, seen from a distance, may; in certain reflections, cause the animal to have a general dark or black appearance. This would be the case with the wolf having such a skin as the one in my collection marked 47. A few memoranda concerning this species, made in connexion with the skin last mentioned, (47,) may be found in my partial report, chap. 2, p. 90. They are exceedingly numerous in Oregon and Washington Territories, from the Cascades to the Rocky mountain divide, and probably extend much further north, east, and south. They are sparingly found west of the Cascades, occurring, according to Mr. Gibbs, on the Clatsop Plains, and have been obtained by me from the elevated plateau at the western base of the Cascade mountains, upon which Muckleshoot prairie is situated. — S. CANIS OCCIDENTALIS, var. NUBILUS. Dusky Wolf. BAIED, Gen Hep. Mammals, 1857, 111. [For synonymy and specific characters see work last quoted ; also chip. 2, p. 90.] The skin obtained by me of this species (or variety?) was from the Nisqually Plains. Formerly this wolf was quite abundant in that vicinity, much to the detriment of the sheep of the Puget Sound Agricultural Company, but, of late years, owing to the persuasive influence of strychnine, they, together with the wolf-like Indian dogs, have become quite scarce. — S. CANIS LATRANS, Say. Prairie Wolf; Coyote. BAIKD, Gen. Rep. Mammals, 1857, 113. Coyotes, apparently identical with the prairie wolf of the plains on the Platte river, I saw in great numbers in Scott's valley in 1851. I also shot one high up in the mountains of Eel river, in California, far from the coast; and in 1854 I again met with them in the Yakima valley, in Washington Territory, north of the Columbia and east of the Cascade mountains. The Chinooks call it Italipus, and believe it to be a sort of demon or deity. — G-. The coyote is common in central Oregon, where it subsists on small game, carrion,
