The Bovidse are strongly developed in Asia and Africa. The 
family has comparatively few representatives in North America 
and none in South America. Four subfamilies occur in eastern 
Asia. 
the true antelopes and gazelles 
(subfamily antilopin^e) 
This is but one subfamily of about ten, the members of 
which, chiefly African, are commonly called Antelopes. Of the 
four or five genera composing this subfamily, three only can 
be found in the extreme west of our region. All of those Ga- 
zelles are of the desert or semi-desert. Brief mention is made of 
one which extends eastward as far as western Jehol, Manchuria, 
and western Hopei. 
The Mongolian Gazelle, Prodorcas gutturosa, is distin- 
guished by the combination of characters : length of tail less 
than 4% inches; inguinal and tarsal glands absent; preorbital 
glands present. The summer pelage is reddish buff, paler on the 
cheeks and flanks, underparts white. A small, area of white sur- 
rounds the root of the tail. In winter the hair is longer and 
paler. The length of the head and body is from 3% to 4 feet. 
The animal stands about 30 inches at the shoulder. 
When making seasonal migrations, these Gazelles gather in 
very large herds in Mongolia at altitudes between 6000 and 
8000 feet above sea-level. During midsummer the old bucks 
separate from the does, and the young, usually 2, are born in 
plains country that affords unrestricted visibility in all direc- 
tions. In the autumn the bucks rejoin the herds. 
WILD CATTLE AND ALLIES (SUBFAMILY BOVINE ) 
These more or less cow-like or buffalo-like animals are, with 
the exception of the little Anoa of Celebes, much larger than
