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®), 9.2, 9; lower molars, 9.8, 10. 
DreMoMyYS 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 principauté de Moupin, ot elle parait fort rare.” ‘Six 
adults were measured by the collector as follows: —

Styan (in DeWinton and Styan, 1899) records this squirrel from western 
Hupeh, northern Kweichow, Anhwei, northwestern Fukien, and Yiinnan, 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
