by a diffused dark line. 1 The horns, which are generally present in both sexes, 
are lyrate or recurved and are compressed, oval in section, and completely ringed 
throughout the greater part of their 
length. The knees are generally 
furnished with tufts of hair. Glands 
are present in the feet, and the gland 
below the eye, if present, is small 
and covered with hair. Most of the 
gazelles do not exceed 30 inches in 
height, although the mohr reaches 
36 inches. There are about twenty - 
one living species belonging to the 
genus Gazella, which are mainly 
found in the deserts of Asia and 
North Africa, although the group 
is represented in South Africa by 
the springbok. Two of the Asiatic 
species are found at great eleva¬ 
tions. Several species of fossil 
gazelles occur in the Pleistocene and 
Pliocene deposits of both Europe 
and India. 
The existing gazelles may be 
divided into several groups, accord¬ 
ing to coloration and the presence 
or absence of horns in the females; 
and, since the species are so 
numerous, we shall content our¬ 
selves with selecting one from each 
group for special notice. 
Our first representative of the genus is the South African 
springbok (Gazella euchore ), which differs from all the other species 
by the presence of a stripe of long white erectile hairs running down the middle 
of the back, and also by having only two premolar teeth in the lower jaw. Both 
sexes are horned. In height the springbok stands about 30 inches, and the black 
horns are lyrate, with about twenty complete rings, and in the males attain a 
length of from 10 to 15 inches. The general colour is dark cinnamon-yellow, but 
there is a dark brown stripe on the flanks dividing the cinnamon colour of the 
sides from the white of the under-parts, and a dark streak running through the 
eye. The general distribution of the white is shown in our figure, but it may be 
remarked that there is more white on the face than in any other species, the dark 
central area of the forehead being reduced to a small patch below the horns. The 
snow-white hairs on the back have a length of 3 or 4 inches.

In eastern South Africa the northern range of the springbok extends to about 
latitude 20°, its limits being marked by the forests south of the Mababi River;
