skin^ these lines are almost black. This seasonal variation is, of 

 course, usual in most if not all members of this genus. 



Genus SCIURUS Linnaeus 



I do not consider that CaJIosciurus is sufficiently well marked to 

 merit full generic standing, and so include the bay-bellied squirrels 

 of China under tlie genus Sciurus. 



SCIURUS ERYTHRAEUS BONHOTEI Robinson and Wroughton 



Soiurus castaneoventrls bonhotei Kobinson and Wroughton, Journ. Fed. 

 Malay States Mus., vol. 4, 1911, p. 234 (Szechwan). 



Specimens. — Nine from Szechwan: Ludin, 1; Mount Omei, 5; 

 Suifu, 1 ; and Kiating, 2. 



These ,skins are not uniform or precisely typical of this race for 

 there is a strong tendency toward black toes; but they are nearer 

 this than any other form. The ears are lilce the back, there is a 

 suggestion of barring upon the tail, and the bay color of the under- 

 parts is dark in tone. 



SCIURUS ERYTHRAEUS CASTANEOVENTRIS Gray 



Sciurus castaneoventris Gray, Ann. Mag. Nat. Hist., ser. 1, vol. 10, 1842, 

 p. 263 (China). 



Specimens. — Four: Kachek, Hainan, 1, and 1 each from Kushan, 

 Peiliang, and Foochow, Fukien. 



These skins are quite typical of this race as now understood. 

 Thomas considers that Hainan examples, named insularis by J. 

 A. Allen, are indistinguishable from mainland specimens. 



SCIURUS ERYTHRAEUS GLOVERI (Thomas) 



Callosciurtis castaneoventris gloveri Thomas, Jourii. Bombay Nat. Hist. 

 Soc, vol. 27, 1921, p. 502 (Nagchuka, Szechwan, China). 



Specimens. — Two from Szechwan: Nagchuka, 1, and Mili, 1. 



The single topotype is paler above than any specimen of this 

 group at hand, the ears are strongly ochraceous, the toes are not 

 black, and the intense rufous of the underparts, including the 

 throat, is in sharp contrast to the gray of the chin. The dark zones 

 of the caudal hairs do not form noticeable blackish tail bars and 

 the tail becomes strongly ochraceous toward the tip. On the whole 

 the Mili specimen is closest to this form but it exhibits an interesting 

 variation showing the influence of other characters, as blackish 

 toes, more ochraceous dorsum, and grayer, lightly banded tail. 



SCIURUS ERYTHRAEUS GORDONI Anderson 



Sciurus gordoni Anderson, Proc. Zool. Soc. London, 1871, p. 140 (Bahmo, 

 eastern Burma).
