MAMMALS, AND REMARKS

By J. A. ALLEN.

ON

The large additions made during the last few months to the collection of mammals in the American Museum include a number of undescribed forms, mainly from the collections of Messrs. W. W. Price and W. W. Granger. Mr. Price's collection, made in southeastern Arizona, alone numbers about 1500 specimens, one-half of which has been purchased by the Museum. The whole collection, however, has been kindly sent by Mr. Price to the Museum for determination, and will form the basis of a special paper on the mammals of southern Arizona, to be published shortly in the Museum Bulletin,' Mr. Price contributing his important field notes, covering nearly a year's work of himself and assistants. In addition to the several new species discovered, his observations and collections greatly extend the hitherto recorded range of many species of mammals. Thus the known range of Tamias cinereicollis, T. lateralis, Sciurus hudsonius mogollonensis, Arvicola alticolus, and Sitomys americanus rufinus has been carried from the San Francisco Mountains southeastward along the Pine Plateau region to the White Mountains, and some of them to the Chiricahua and Graham Mountains; and the large Nyctinomus macrotis nevadensis, described by Dr. Harrison Allen from Nevada, has been found by Mr. Price in the Chiricahua Mountains. Much light has also been thrown upon the range of various other species in southern Arizona.

Mr. Granger's collection, numbering over 500 specimens, collected mainly in South Dakota, contains several species new to the fauna of the Black Hills region, and will also be made the subject of a special report.

The measurements given in the following paper were taken by the collector from the fresh specimen before skinning, unless otherwise stated.

Perognathus pricei, sp. nov.

Above gray, lined with black; no fulvous lateral line; beneath white; tail strongly crested penicillate, dark above, becoming blackish distally, white below; ears dusky feet grayish white, soles naked. Pelage rather harsh but not spiny.

Measurements.-Total length (type),

157 mm.; tail vertebræ, 90; pencil at Average of 5 adult specimens (4 **)

Total length, 151; tail vertebræ, 82; hind foot, 22; ear, 8.

Skull.-Total length, 23; basilar length, 18; mastoid breadth, 12; length of nasals, 8; breadth of interparietal, 8; greatest length of interparietal, 4; length of mastoid area, 12. The interparietal is large, distinctly pentagonal, twice as broad as long. The mastoid area is correspondingly reduced.

ad., Oposura, Sonora, May 31, 1894; B. C. Condit

Named for Mr. W. W. Price, in recognition of his important mammalogical explorations in southern Arizona.

This species is based on 5 adult specimens (4 males and I female) taken at Oposura, Sonora, May 30 and 31, 1894, by Mr. B. C. Condit, of Mr. W. W. Price's Arizona Expedition.

This species appears to bear no close resemblance to any hitherto described. In color it somewhat resembles P. intermedius Merriam, which is, however, a much larger species, with very different cranial characters, and not nearly so clear gray.

Perognathus conditi, sp. nov.

Above yellowish gray, lined with black; a broad pale fulvous lateral line; feet and lower parts white; ears grayish dusky; tragus about as high as broad; tail dusky above, white below, not crested, and only very slightly tufted at the end. Soles naked.

Measurements.—Total length (type), 197 mm.; tail vertebræ, 88; hind foot, 27; ear, 10. Another specimen ( ad.), measures: Total length, 193; tail vertebræ, 87; hind foot, 24.5; ear, 12.

Skull.-Total length, 29; basilar length, 24; greatest mastoid breadth, 14; length of nasals, 10.5; breadth of interparietal, 7; greatest length of interparietal, 5. The interparietal is large, pentagonal, with the posterior lateral borders much rounded; mastoid area only moderately developed.

1 Front border of intermaxillæ to posterior border of occipital condyles.

8360

Type, No. 8, & ad., San Bernardino Ranch, southeastern corner of Cochise Co., Arizona, March 23, 1894; B. C. Condit (Price Collection).

Named for Mr. B. C. Condit, an associate of Mr. Price in his explorations in Arizona.

This species should probably be compared with P. baileyi Merriam from Sonora, but it is apparently smaller, more fulvous, with the tail less crested, and the interparietal more pointed in front and more rounded on the postero-lateral borders.

Represented by 3 specimens (1 ad. ♂, 1 young ad. 3, and 1 ô juv.) taken at San Bernardino Ranch, Cochise Co., Arizona, March 23 and May 1, 1894. The young specimen is grayer and less fulvous than the adults, the type being scarcely distinguishable in color from Kansas and South Dakota specimens of P. paradoxus, and the tail is quite as sparsely haired. In fact, in point of color, P. conditi is not readily distinguishable from specimens of P. paradoxus from the southeastern base of the Black Hills; and cranially the differences are by no means strongly marked.

Reithrodontomys mexicanus fulvescens, subsp. nov.

Above yellowish brown, more or less heavily lined with black; a bright, strongly marked fulvous lateral line; below whitish, the basal two-thirds of the pelage plumbeous; ears dusky externally, rusty within, well clothed with fine short hairs; tail indistinctly bicolor, pale brown above, lighter below, sparsely haired, but the hairs pretty thoroughly concealing the annulations; feet soiled white, heels sparsely covered as far as the first tubercle with fine short hairs. Measurements.-Total length (type), 183 mm.; tail vertebræ, 102; hind foot, 19; ear, 14. Average of three adults (2 5, 19): Total length, 172; tail vertebræ, 99: hind foot, 19.3; ear, 14.7. Eight adult specimens of R. mexicanus from Brownsville, Texas, average: Total length, 178; tail vertebræ, 98; hind foot, 20.

8411

Type, No. 1, ↑ ad., Oposura, Sonora, June 1, 1894; B. C. Condit (Price Collection).

This subspecies is represented by three adult specimens taken by Mr. B. C. Condit at Oposura, Sonora, May 31 and June 1, 1894. It presents an astonishingly close resemblance, in size and proportions, to September specimens of R. mexicanus' from

The type locality of R. mexicanus (Saussure) was Tehuacan, State of Puebla, Mexico, from which region, however, no material is at present available for comparison.
