skull without a skin ; the skull was said to be less flattened than 
is usual. 
The first species, C. hypsibia, comes from northern Szechwan. 
It and C. h. lowei of western Tonkin, 10,000 feet, are the largest 
of the races. All races of this group have smaller feet than 
smithii or salenskii. Two further races, C. h. lamula from 
Kansu, 9500 feet, and C. h. larvarum from the lowlands of the 
Province of Chihli, 1000 feet, have substantially the same 
dimensions, the length of head and body in each about 
2y 2 inches. The smallest race, C. h. parva, from Yunnan, has 
the length of the head and body only a little more than 2 
inches. 
The species C. smithii consists of three races of substantially 
equal size, C. smithii from Szechwan at 9000 feet, C. s. parca 
from western Yunnan, 8000 feet (in northern Siam at 8000 
feet, in Burma from 4000 to 6000 feet), and C. s. furva from 
northeastern Burma. The last is even darker than the usually 
dark-colored forms of this genus. The first two races are distin- 
guished by their mouse-gray dorsal coloring and brown tails, 
true smithii having the tail equal to the length of head and 
body, parca having it longer in proportion. 
Chodsigoa salenskii from northern Szechwan, with its ex- 
treme length of tail, appears to be unique. The body is sharply 
bicolored, dark brown above, brownish white below. The length 
of head and body is 3% inches, tail 4% inches, hind foot 
% inch. Most other forms of Chodsigoa are colored as in Sori- 
culus, dark grayish brown above, paler beneath. The ears appear 
prominent and nearly naked. 
Chodsigoa hypsibia is normally sooty brown except around 
the mouth and tip of tail and extremities which are whitish. 
C. h. lowei is very similar, with higher, fuller braincase. C. h. 
parva is "deep mouse gray," scarcely paler beneath; the tail 
beneath whitish. C. h. lamula is colored very like the type form. 
C. h. larvarum, though of the same size as lamula, is a lowlands
