the Cavicornia are to be regarded as being the most typical 
examples of the Awminantia, and they include a number of 
animals which are of the highest utility to man. 
The Antelopes form a very extensive group, closely resem- 
bling the true Deer, but distinguished by the possession of hodlow 
horns, in place of so/zd antlers. Most of the Antelopes are 
African, and there are only two European forms (the Chamois 
being one), while America possesses only the Prong-buck (A zéz- 
lope furcifer). Among the more familiar African species may 
be mentioned the Gazelle, the Koodoo (fig. 178), the Gnu, the

Gemsbok, and the Springbok. The Sheep and the Goats 
(Ovide@) are closely allied to one another, and are well known by 
their domestic varieties. All the Sheep appear to be natives of 
the Old World, with the exception of the “ Bighorn” (Ovzs 
montana) of the Rocky Mountains. Among the true Oxen 
(Bovide) the most important species is the domestic Ox (Bos 
taurus) with its innumerable varieties. The true Buffalos 
(Bubalus) ave natives of Asia and Africa, and are characterised 
by their wide horns united at the base. The American Buffalo, 
or Bison, as it is properly called (Bzsou Americanus), is dis- 
tinguished by its enormous head, shaggy mane, and conical 
hump between the shoulders, America also possesses another 
singular Ox in the person of the Musk Ox (Ovibos moschaius), 
which is found north of the 6oth parallel, and is remarkable for 
its small size and long, woolly coat.
