ART. 1 MAMMALS FROM CHINA HOWELL 39 



this name should be placed in synonymy, for two subspecies of one 

 species are herein assigned to this one mountain range — a procedure 

 which seldom conforms to good usage. But in other instances the 

 evidence is rather conclusive that two subspecies may occur on dif- 

 ferent slopes of this mountain range. Because there is so much 

 variation among the Likiang Dremomys^ then, the race lichiensis 

 may possibly prove to be untenable. If it is valid, however, then 

 these two specimens are the only ones among those at hand that may 

 be assigned to it. They were taken in April and July and are very 

 buffy, with the anal patch of large extent and the postaricular area;9 

 conspicuous. 



DREMOMYS RUFIGENIS LENTUS A. B. Howell 



Dremomys rufigenis lentus A. B. Howell, Journ. Wash. Acad. Sci., vol. 17, 

 1927, p. 80 (near Wenchuanshein, Szechwan, China, at 6,000 feet altitude). 



Specimen. — One, the type. 



This race is based upon the uniformity of coloration of the flanks, 

 back and cheeks. The rufous of the underparts is confined to the chin 

 and upper lips, anal region, and faintly along the inner margin of 

 the hind legs. The postauricular spots are buffy. 



Genus SCIUROTAMIAS Miller 



SCIUROTAMIAS DAVmiANUS DAVmiANUS (Milne-Edwardg) 



Sciurns damdianus Milne-Edwards, Rev. Zool., vol. 19, 1867, p. 190 (Peking, 

 Chihli, China). 



Speoimens. — Twenty seven : Hsinlungshan, 2, Wulingshan, 2, 

 Chingwangtao, 11, and 15 miles west of Peking, 1 — the foregoing in 

 Chihli ; mountains northwest of Taiyuanfu, 9, and mountains 10 miles 

 south of Wutai, Shansi, 1 ; and 15 miles east of Yenanfu, Shensi, 1. 



The Shensi example varies toward ovjsteni. 



SCIUROTAMLAS DAVmiANUS OWSTENI J. A. Allen 



Sciurotatmas owsteni J. A. Allen, Bull. Amer. Mus. Nat. Hist., vol. 26, 1909, 

 p. 428 (Taipeishan, Shensi, China). 



Specimens. — Fourteen: Luitsuen, near Sianfu, 4; near Chingchien- 

 shein, 2 ; and Taipeishan district, 80 miles west-southwest of Sianfu, 

 3 — the foregoing in Shensi : the following in the province of Szech- 

 wan — Wenchuen, 1 ; Sungpan, 2 ; and Ludinchiao, 1. And one from 

 Hwangtsaopa, Kweichow. 



One from near Chingchienshein varies toward typical davidianiis. 

 Than the latter this race is a trifle larger Avith brighter, browner 

 back, tail and feet, more richly colored underparts, and there is a 

 strong suggestion of white striping extending caudad from the ears.
