256 Mammals of Eastern Asia 
is like American White-footed Mice with the exception of the 
tail, which is much shorter. In some the back is striped. Cheek 
pouches are present. Five species with twelve subspecies occur 
in China, but of these only three come within the scope of 
this work. 
East Asiatic Cricetidus, of which C. griseus is the type, with 
head and body 4 1 / 4 inches, tail 1% inches, hind foot % inch, 
is separable into several groups based upon size. In the typical 
size group may be placed C. g. fumatus from Manchuria, 
C. longicaudatus from Pekin, C. alticola from Ladak and Tibet, 
and C. manchuricus from northern Manchuria. C. longicaudatus 
is colored buffy drab above ; the underparts are white with gray 
hair bases; the hands, feet, and underside of the tail are pure 
white, and the ears blackish. 
A second size group, in which the tail is longer though the 
feet remain small, includes the white- footed C. triton, dis- 
tributed from Shantung and Honan to Chihli, and C. kamensis 
from northeastern Tibet. In these the length of the tail exceeds 
2 inches. In the third size group the hind foot is also propor- 
tionately larger. Here are included C. nestor from Korea and 
C. arenosus from northeast Jehol, which has the basal parts of 
the feet dark. 
The Mice of the genus Cricetidus make burrows. In their 
cheek pouches they carry seeds and bits of leaf, which are stored 
in large underground chambers. 
The Least Hamsters, Cricetiscus songarus campbelli from 
northeastern Mongolia, and C. crepidatus from the Altai, are 
small Hamsters related to Cricetidus. In Cricetulus the white 
of the underparts extends upward as conspicuous white patches 
in front of and behind the shoulders. The upperparts are ochra- 
ceous and buffy gray. A line along the back is blackish. In C. 
campbelli, the length of head and body is 3% inches, of the tail 
only 14 inch, hind foot y 2 mcn - C. crepidatus is larger ; the head 
and body measure 4 inches, the tail and foot both y 2 inch.
