A “TREK OF SPRINGBOK. 
The large and extensive group of 
antelopes known as gazelles brings 
us to the first of an assemblage of 
several widely-spread genera, differ¬ 
ing considerably from those yet 
noticed. Most of these antelopes 
are of small or moderate size, and the majority of them are inhabitants of the 
deserts of the Old World. The whole of them have narrow upper molar teeth 
like sheep, and their muzzles are similarly covered with hair. There is very 
frequently a gland below the eye, and the tail is either short or of moderate 
length. As a rule, the horns are compressed and lyrate or recurved, or 
cylindrical and spiral, with distinct rings for a considerable portion of their 
length. The skull has large pits in the forehead. 
The gazelles are among the most elegant of all antelopes, and are characterised 
by their sandy colour and the presence of a white streak on the side of the face 
from the base of the horn nearly to the nose, thus cutting off a dark triangular 
patch in the middle of the forehead, while the streak itself is bordered externally
