182 Hollistei — Five New Mammals from Asia. 



Le pus sinensis from Shanghai is remarkable; buta careful comparison of 

 the two species discloses differences of such weight, that it seems un- 

 likely they are of the same group, or that intergradation is possible. 



Lepus quercerus sp. nov. 



Type from Chuisaya Steppe, Altai Mountains, Siberia. United States 

 National Museum No. 175,446, skin and skull of cj 1 adult. Collected 

 July 28, 1912, by N. Hollister. Orig. No. 4405. 



General characters. — Like Lepus zaisanicus Satunin, but with much 

 longer ears, much less gray, and with a tint of vinaceous-buff throughout 

 coloration of upperparts. 



Color of type. — General color of upperparts and sides pinkish-buff, 

 mixed with blackish, and with a decided tint of vinaceous-buff. Sides of 

 nose and base of ears gray; inside of back of ears pale Isabella color, 

 huffy at fold; outside of back nearly white; lining of ears white, a dark 

 brown stripe, for two-thirds the length, near border of buff; tips blackish, 

 extending downwards for 15 millimeters on outside, but showing from 

 inside only as a narrow rim. Nape clay color; rump grayer than back, 

 lacking most of the huffy and vinaceous-buff wash. Tail white, with 

 broad black band above. Outsides of legs pale cinnamon; chest-band 

 dark clay color; rest of underparts, including insides of legs, white, the 

 underfur narrowly gray at base. 



Skull. — Differs from skull of L. zaisanicus in narrower interorbital 

 region, closely compressed posterior lobe of supraorbital process, attenu- 

 ated nasals, and less protruding incisors. 



Measurements of type.— Head and body, 470 mm. ; tail vertebrae, 86; 

 hind foot, 115. Skull : Greatest length, 82; basal length, 64.5 ; zygomatic 

 breadth, 41.5; greatest length nasals, 34.2; least interorbital breadth, 

 14. S; alveolar length of upper tdothrow, 14. 3. 



Remarks. — Hares collected in the frontier range of the Little Altai, in 

 the neighborhood of Tchegan-Burgazi Pass, have been provisionally re- 

 ferred to Lepus zaisanicus Satunin, with the description of which they 

 agree very well. As Satunin does not describe nor figure the skull of this 

 hare, it is of course impossible to say just what the relationship is. In 

 the foregoing description of the hare of the Chuisaya Steppe, the compari- 

 sons are made with these specimens from the Tchegan-Burgazi Pass. The 

 difference in color between the two species is even more pronounced in 

 specimens in the Juvenal and post-juvenal pelage than in the adults. 

 The young of the species I have referred to L. zaisanicus are gray, while 

 the young of L. quercerus in comparable pelage are decidedly yellowish- 

 buff. 



Lepus swinhoei sowerbyae subsp. nov.

 China; 6000 feet. United States National Museum No. 172,628, skin and

 Orig. No. 365.
