ZOOLOGY. 



Indian -wild cattle: The tsine and the gaur (miscalled bison), Pollok 

 (Zoologist, 4. ser., 2 (1898), No. 13, pp. 1-10). — The tsine (Bos sondaicua) and the gaur 

 (B. gaurus) are discussed by a hunter. Two distinct forms of the latter species are 

 found, known as the gaur and the gayal. At a distance both look alike, but the 

 gaur's head has a semicylindrical crest and a concave forehead. The head of the 

 gayal has neither. In the gaur again there are two varieties, distinguished by the 

 natives as jungle cow and jungle buffalo. One has a large dewlap, the other scarcely 

 any, or none. When captured the animals, after passing through a period of great 

 pugnacity, become very tame. 



Preliminary description of a new mountain sheep from the British North- 

 west Territory, J. A. Allen (Bui. Amer. Mas. Nat. Hist., 9 (1897), pp. 111-114, pis. 

 2). — The species Oris stonei differs from 0. dalli in being dark gray or blackish brown. 

 This coloration also distinguishes it from 0. cervina, which is umber brown or wood 

 brown. It is also a smaller animal than the latter. Three specimens were obtained 

 from the head waters of the Stickeen River, in British Northwest Territory, near the 

 Alaskan boundary. 



Description of a new deer (Dorcelaphus texanus) from Texas and northern 

 Mexico, E. A. Meakns (Proc. Biol. Soe. Washington, 12 (1898), pp. 23-26). 



Descriptions of six new ground squirrels from the Western United States, 

 C. H. Merriam ( I'roc Biol. Soe. Washington, 12 (1898), pp. 69-71). — Spermophilus ore- 

 gonus from Swan Lake Valley, Oregon ; S. mollis stephensi from Owens Valley, Nevada ; 

 S. mollis yakimensis from Yakima County, Washington; S. mollis canus from Wasco, 

 Oregon; S. tridecemlincatus alleni and S. tridecemlineatus texensis from Cook County, 

 Texas. 



Descriptions of two new skunks of the genus Mephitis, O. Bangs (Proc. Biol. 

 Soe. Washington, 12 (1898), pp. 31-33). — Mephitis spissigrada from Sumas, British 

 Columbia, and M. avia from San Jose, Illinois. In general appearance the former 

 much resembles M. hudsonica and M. occidentalis, into which two species it inter- 

 grades. The other species is small, with a very short and bushy tail and a peculiar 

 skull. It is black everywhere except a white frontal stripe and nuchal patch and 

 two lateral or subdorsal white stripes passing backward from the nuchal patch. 



Descriptions of the Newfoundland otter and red fox, O. Bangs (Proc. Biol. 

 Soe. Washington, 12 (1S9S), pp. 35-38). — Lutra degener, n. sp., and J'uhyes deletrix, n. sp.
