CHAEACTEES. 
Size of Tamias Lysteri ; a narrow white stripe on each side of the hack, 
from the shoulder to the thighs ; forehead reddish-grey J neck ashy-white 
running into yellowish iron-grey on the back ; under surface ashy white ; tail 
distichous. 
DESCRIPTION. 
Head small and delicate ; neck, rather long ; body slender ; legs rather 
long, a few long hairs growing out and fringing the hind parts of the fore 
legs ; the cheek pouches appear rather small in the dried specimen ; ears 
thinly clothed on both surfaces with short adpressed hairs ; short, some- 
what triangular, and rather acute at the tips ; tail of moderate length, 
depressed at base, with the hairs growing from the side, giving it a 
decidedly distichous appearance ; the teeth resemble those of T. Lysteri ; 
are rather small, and the lower incisors are slightly curved. 
Whiskers not numerous, reaching the ear ; hairs on the back very short, 
somewhat coarse, but lying very smoothly, giving the animal a glossy 
appearance ; on the under surface they are coarse and rigid. There are 
five toes on each foot ; on the fore-feet a small tubercle in place of a thumb, 
with a blunt nail ; second nail from the thumb longest, as in the rest of 
the spermophili ; on the hind feet the middle toes are longest, the two on 
each side being of nearly equal length, the outer considerably shorter, and 
the inner shortest ; claws slightly compressed, and a little curved ; feet 
clothed with short hairs, but which do not conceal the nails ; the eyes are 
of moderate size, and are placed midway between the point of the nose and 
the root of the ear • soles of feet tuberculated and naked, except a few 
hairs between the toes.
