228 SOME CHINESE VERTEBRATES. 



layanus. Mr. Zappey obtained an adult female from Shuowlow, in the western 

 border of Szechwan, at an altitude of 15,500 feet and a smaller specimen from 

 Kaoerhshan, a few days later at a similar elevation. The color is less ochraceous 

 than that represented in Milne Edwards's plate, more nearly a cream-buff. 

 The adult specimen measured by the collector: total length, 705; tail, 135; 

 hind foot, 88. The skull measures: greatest length, 103; basal length, 94; 

 palatal length, 57; zygomatic breadth, 64; breadth between tips of postorbital 

 processes, 46; postorbital constriction, 17.3; mastoid breadth, 46; upper 

 diastema, 27 ; mandible from condyle to tip of incisor, 79 ; upper molar row, 23 ; 

 lower molar row, 22.3. 



DREMOMYS PYRRHOMERUS (Thomas). 



This squirrel has been recorded from Ichang, Hupeh, and Sinyang, Kweichow, 

 to the southwest. Mr. Zappey obtained three specimens from Hupeh, one at 

 Tongkowshih, and two from Changyanghsien. Two of the skulls measure as 

 follows: greatest length, 57, 56.3; basal length, 44, 42; nasals, 19, 19.3; 

 zygomatic breadth, 31, 30; interorbital constriction, 17, 16; upper diastema, 

 13, 13.4; upper tooth row (excluding p 3 ), 9.2, 9; lower molars, 9.8, 10. 



DREMOMYS PERNYI (Milne Edwards). 



Twelve specimens of this species were obtained by Mr. Zappey in the 

 mountains of western Szechwan at the following localities: Tachienlu, 9,000 

 feet; Nachuka, 12,000 feet; Ramala Pass, 12,500-13,000 feet; and Shuowlow, 

 13,000 to 14,000 feet. Milne Edwards's specimens came also from Szechwan and 

 "les montagnes de la principaute de Moupin, ou elle parait fort rare." Six 

 adults were measured by the collector as follows: 



Styan (in De Win ton and Styan, 1899) records this squirrel from western 

 Hupeh, northern Kweichow, Anhwei, northwestern Fukien, and Yunnan, and 

 states that it is a mountain species, probably not descending below 3,000 feet. 

 Two specimens collected by Mr. Zappey in the neighborhood of Ichang, Hupeh, 

 however, are quite different from our series of D. pernyi, and are here described
