1903.] Allen, Mammals from Northeast Siberia. 159 



"Russian name, Zaisch; Siberian name, Oo-skon. An 

 abundant resident in suitable localities at all places that I 

 visited in Northeast Siberia. I saw it at Okhotsk, Ola, 

 Gichiga, and Marcova. Mr. Jochelson says that it is abun- 

 dant along the Kolyma River and its tributaries, and that a 

 few [Lepus tschuktschornm] were found near the New Marine 

 Post at the mouth of the Anadyr. Along all the streams, and 

 wherever there was a growth of trees or bushes between 

 Gichiga and Marcova, I saw evidences of them. In many of 

 these places the snow was simply packed down by their feet 

 and littered with their droppings. They are especially fond 

 of the bark of the young willows, and I have seen sprouts 

 entirely stripped of the bark for a distance of three feet above 

 the snow, and others over two inches in diameter entirely 

 gnawed in two. They are never seen during the day unless 

 startled from their burrows in the snow-drifts or under fallen 

 trees, but they are very active at night, especially clear ones. 

 They seldom stray far from their feeding-grounds and are 

 never seen on the open tundra. The Russians catch them 

 during the winter in deadfalls and use the meat for food and 

 the skins for bedclothing. Every family has a number of 

 bed blankets made from their skins, and they are very warm 

 and serviceable. A skin has a local value of about 5 cents."

20. Lepus tschuktschorum (Nordquist). 

 CHUKCHE HARE. 



One specimen, in full winter pelage, obtained at Chaplin 

 Point (Indian Point of Americans), extreme northeastern 

 Siberia, by Mr. W. Bogoras, the date being " Fall, 1901." No 

 measurements were taken from the fresh specimen, but such 

 measurements as can be obtained from the skin show it to 

 be larger than the average size of L. gichiganus, slightly ex- 

 ceeding even the largest specimens of that form. Thus, the 

 ear from the crown measures 13 mm. longer than the average 

 length in gichiganus and 8 mm. more than the largest; while 

 the hind foot (measured in the dry skin in each case) is 10 mm.
