Descriptions of East Asiatic Mammals 323 
shoulder, without the neck mane, and having the coat thicker 
and more woolly and the tail more bushy. The first group con- 
tains the Southern Serows of the Malay region, Burma, and 
southern China, and the White-maned Serow; the second in- 
cludes the Japanese and Formosan Serows. 
The Southern Serow, Capricomis sumatraensis, is distrib- 
uted over an enormous range, within which are a number of 
local races. As its name implies, it was described originally from 
Sumatra. The color varies from black to reddish, with the mane 
partly gray and with varying amounts of white or grayish 
white on the legs. The form in the Malay Peninsula, C. sumat- 
raensis swettenhami, found between 2000 and 4000 feet, is only 
weakly separable from the Sumatran animal. The general color 
is grizzled blackish gray, the legs black (they are reddish in the 
Sumatran race). The underparts are black except the insides 
of the thighs, which are rusty red. The tail is black. 
In the uplands of Szechwan, Yunnan, and Burma a local race, 
C. s. milne-edwardsi, occurs, which has the upperparts blackish 
brown, the underparts dull dark brown, the shanks reddish, and 
the mane of mixed black and gray hairs. There is a spot of tan 
on either side of the muzzle. 
In the Arakan Hills of southwest Burma the form C. s. rubi- 
dus has the pelt prevailingly red all over. North of there, in 
Darjiling, C. s. jamrachi is black, with brownish yellow behind 
the upper lip and at the base and on the backs of the ears. The 
throat and chest are black. The fetlocks are white; just above 
them the legs are brown. 
In eastern China the White-maned or Eastern Serow, C. s. 
argyrochcetes, is the local representative. Its coat is dull, deep 
brown, with a well-developed white throat patch and the sides 
of the muzzle dark brown. The mane may sometimes be whiter 
than in other races. 
C. s. maritimus, of Tonkin, Laos, and Annam, was described 
by Heude as "brownish, smaller than C. s. argyroch&tes," and
