ART. 1 MAMMALS FROM CHINA — HOWELL 43 



illuminating, but his character of the shoulders and lower portion of 

 the back being suffused with tawny-ochraceous fits some of my spec- 

 imens. All of these skins, possibly with the exception of two, were 

 taken in November, and yet the variation is so marked that extremes 

 might be presumed to represent two well-marked races. There are 

 skins, hoAvever, showing merging of characters to different degrees, 

 and sufficient is not yet known regarding the seasonal and age varia- 

 tion of the Tamioj}s to make me willing to describe a new race based 

 upon any of these specimens. In the brighter examples the dorsum 

 shows much ochraceous tawny, the more lateral pale stripes are 

 strongly ochraceous, and there is but a single dark stripe, which is 

 very short. At the other extreme is a grayish tone of pelage, but 

 with the head as ochraceous as in the opposite " phase" of pelage. 

 These have three dark dorsal stripes that are almost black, and the 

 lateral light stripes are buffy, sharply marked, and very broad. 



TAMIOPS MACCLELLANDI SWINHOEI (Milne-Edwards) 



Sciurus macclellandi svnnlwei Milne-Edwards, Rech. Mamm., 1874, p. 308 

 (Muping, Szechwan, China). 



/Specimens. — Two from Szechwan: Wenchwan, 1, and Washan, 1. 



These summer skins, with the three black dorsal stripes normal to 

 the pelage of this season, are quite typical, and the paler stripes are 

 much more strongly ochraceous than in any other race. 



TAMIOPS CLARKEI Thomas 



Tamiops clarkei Thomas, Ann. Mag. Nat. Hist., ser. 9, vol. 5, 1920, p. 304 

 (Yangtze Valley, northern Yunnan, China). 



SpedTrmn. — One from 8,000 feet upon the east slope of the Likiang 

 Mountains, Yangtze Gorge, Yunnan. 



This specimen is very distinctive. There is no date of capture 

 but the dark dorsal stripes are sharply contrasting and there is an 

 additional pair laterally that are almost as dark as the others. The 

 tips of the caudal hairs are whitish, rather than ochraceous, and the 

 subauricular stripes are pure white. 



TAMIOPS VESTITUS Miller 



Tamiops vestitus Milleir, Proc. Biol. Soc. Wash., vol. 28, 1915, p. 115 (65 

 miles northeast of Peking, Chihli, China). 



Specimens. — Fourteen from Chihli : 80 miles east of Peking (East- 

 ern Tombs), 2; and Hsinglungshan, G5 miles northeast of Peking, 12 

 (including the type). 



This form is so distinct that I regard it as very doubtful whether it 

 intergrades with any race of fna-cclellandi. Winter skins have the 

 lateral stripes dull and almost like the flanks, whereas in summer
