ART. 1 MAMMALS FROM CHINA HOWELL 37 



Genus CITELLUS Oken 



CITELLUS DAURICUS MONGOLICUS (Milne-Edwards) 



Spermophilus mongolicus Milne-Edwaeds, Ann. Sci. Nat., vol. 7, 1867, p. 376 

 (northwest Chilili, China). 



Specimens. — Thirty-two : near Peking, 1, Tientsin, 4, Tabul, 4, and 

 west of Lamamiao, 6 — the foregoing in Chihli; Tungkwan, 1, and 

 vicinity of Sianfu, Shensi, 1; Lanchowfu, 12, and Chingningchow, 

 Kansu, 3. 



G. M. Allen (1925) stated "specimens obtained — near Peking are 

 therefore topotypes," but this is slightly misleading for Thomas 

 (1908) had already fixed the type locality for this animal as 

 Suanhwafu, Chihli, some 90 miles northwest of Peking. There is 

 great variation in this type of ground squirrel, this apparently being 

 due chiefly to age and to a lesser extent to season. In the skins 

 before me there is fully as much individual as geographic variation, 

 with the palest individual and one of the darkest from the same 

 locality. Hence there is no choice but to call them all the same thing. 



CITELLUS EVERSMANNI EVERSMANNI (Brandt) 



Spermophilus eversmanni BpvAndt, Bull. Acad. Imp. Sci. St. Petersb., vol. 9, 

 1&41, p. 43. 



Specimen. — One from the Tianshan Mountains, Sinkiang. 

 Genus DREMOMYS Heude 



DREMOMYS PERNYI PERNYI (Milne-Edwards) 



Sciurtis pernyi MiLNE-EipwARus, Rev. Zool., vol. 19, 1867, p. 230 (Szechwan, 

 China). 



Specimens. — Nine from Yunnan: From 9,500 to 12,000 feet, 

 Likiang Mountains, 4; Hofuping Mountains, Mekong Valley, 3; 

 Yangtze Mountains, 1 ; and Chuchi, 1. 



The Hofuping and Yangtze Mountain specimens are undoubtedly 

 fairly representative of the typical race of this species but examples 

 from the same locality exhibit appreciable variation in the degree 

 of buffiness shown. The Chuchi skin has a strong overwash of 

 ochraceous upon the whole medial side of the thigh, although the 

 throat is white. It does not approach hoivelU, mentosus, or i7Jius, 

 and merits separation if the characters which it exhibits should prove 

 to be uniform. The Likiang specimens listed under this race cannot 

 be identified as lichiensis, for they are distinctly too gray and close 

 to pernyi. Three of them are excessively worn dorsad. The race 

 lichiensis may be invalid or there may have been a recent infusion 

 of individuals of the typical race into a part of these mountains, 

 if the surrounding topography renders this a possibility. G. M.
