ADDAX,—Addax nasomaculatus. 
The Oryx is a native of Northern Africa, where it is known under several names ; 
such as Abou-Harb, El-Walrugh, El-Bukras, Ghau-Bahrein, or Jachmur. It lives in 
herds of considerable size, and feeds mostly on the branches and leaves of a species of 
acacia. 
The ApDAX is found in many parts of Northern Africa, and is formed by nature for a 
residence among the vast plains of arid sand which are spread over that portion of the 
globe. 
These animals are not found living together in herds, but in pairs, and their range of 
locality seems to be rather wide. As they are intended for traversing large sandy regions, 
the feet are furnished with broad, spreading hoofs, which enable them to obtain a firm 
foothold upon the dry and yielding sand. The horns of this animal are long, and twisted 
after a manner that reminds the spectator of the Koodoo, an Antelope which will shortly 
be described and figured. Measured from the tip to the head in a straight line, the horns 
are about two feet three inches in length; but if the measurement is made to follow the 
line of the spiral, the length is obviously much greater. The distance between the tips is 
about the same as that from the tip to the base. From their roots to within a few inches 
of their extremities, the horns are covered with strong rings, arranged in an oblique 
manner, and some of them partially double. The spiral of the horns is as nearly as 
possible two turns and a half. 
Upon the forehead there is a bunch or tuft of long hair, and the throat is also covered 
with a rather heavy mane of long hair, but there is no mane on the back of the neck. 
The muzzle and nose are rather peculiar, and bear some resemblance to the same parts of 
a sheep or goat. The general colour of the Addax is a milk-white, with the exception of
