curve backwards, and approximating terminally, with the 

 tips bent upwards in a well-marked curve ; in addition to 

 this simple curvature the middle portion of each horn is bent 

 outwards in a lyre-shape, so that the larger diameter of a 

 transverse section above is in quite a different plane to what 

 it is lower down, and it is in consequence of this lyrate form 

 that the horns, quite apart from the tips, are approximated 

 terminally, whereas in other species such approximation is 

 due solely to the incurving of the tips.* General colour pale 

 sandy fawn, somewhat variable in tone individually; fore- 

 head and median face-stripe rufous fawn, generally without 

 a nose-spot, lateral face-stripes brownish fawn ; ears rather 

 long (about 4^ inches), whitish fawn on backs ; flank-band 

 brown, considej'ably darker than back ; pygal band indistinct. 

 In a typical specimen the basal length of the skull was 

 6| inches, the maximum breadth 3|, and the length from 

 muzzle to orbit 3| inches ; some distinctive features of the 

 skull are mentioned under the heading of littoralis. Fine 

 horns measure from 12 to 13| inches in length, with a basal 

 girth of from 3^ to 4J. 



The range includes Egypt, Abyssinia, Kordofan, Tripoli, 

 the Algerian Sahara, and the Lake Chad district.
