The females are hornless. Except the newly discovered gazelle 

 hereinafter mentioned, I believe this is the only African species 

 of gazelle of which the females have no horns. This gazelle 

 is found on the flat desert and in the low hills near the coast and 

 also on the plateau. It is generally seen on ground where there is 

 plenty of bush, although I have seen it out on the open desert near 

 bush. It is quite common and difficult to stalk. It feeds chiefly 

 on the bushes, and in my opinion seldom if ever drinks. The Somalis, 

 although they eat all the other antelope except the klipspringer (and 

 I am not quite sure they don't eat that), won't eat this gazelle; the 

 reason given to me was a curious one and unfit for publication. 

 The flesh is good. As pointed out by Sir Victor Brooke in the 

 P. Z. S., 1878, p. 929, Gazclla walleri differs from all other species of 

 gazelle in the very great backward prolongation of the occiput, and 

 in the shortness and width of its grinding teeth. The lower jaw, too, 

 is more slender than one usually finds in gazelles. It has been made 

 the type of a distinct genus under the name of Idthocranius wallert 

 by Dr. Kohl. Mr. H. C. V. Hunter, who shot this gazelle on the 

 Tana River to the south of the Somali country, told me the horns 

 there were not so thick as those described above. 



In the P. Z. S., 1891, p. 207, a new gazelle, recently discovered in 

 Somali land, is described under the name Amnwdorcas Clarkei, of 

 which the females are said to be hornless. 



Oazella scemmerringii 

 Is a much stouter built animal than Gazclla walleri, and is of a 

 pale fawn colour with under parts white. Its rump is pure white. It 

 was not common in the part of the country I was in. In fact, I only 

 saw one herd of six and a solitary buck, the latter I shot. I was told 

 they were common on the Bulhar plain, a few miles west of the line I 

 took, and that they are found in large herds. The horns are longer 

 and thicker than those of Gazclla walleri. The horns curve backwards, 

 then outwards, and the tips curve in towards each other. The one 

 head I have measures — 



Length on curve along upper surface, 15 £ inches. 



Straight line from base to tip, 13 inches. 



Between tips, 4 inches. 



Round base, 5.^ inches.
