THE ADDAX.

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 

 cf considerable size, and feeds mostly on the branches and leaves of a species of acacia. 



The ADDAX 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 measure- 

 ment 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 color of the Addax is a milk-white, with the exception of
