Hah. Sand-dunes of Oued Souf, about 100 miles south of 

 Biskra. (See field-notes by Sir E. Loder, p. 473.) 



This remarkable little Grazelle is readily distinguishable from all 

 other species by its pallid colour, semi-obsolete markings, slender 

 divergent horns, and long narrow hoofs. 



Its habitat, as may be seen by the field-notes of its collector, is 

 somewhat inaccessible, and it is therefore the less surprising that 

 examples fit for description have not previously fallen into the 

 hands of naturalists. Its horns have, however, long been pur- 

 chasable at Biskra, and the first I had seen w^ere bought there 

 by Mr. Rowland Ward, and submitted to me for examination 

 about two years ago, but the horn characters were too little marked
