ON A NEW FORM OF GRANT S GAZELLE. 



[June 16, 



stated among other things that all of the Gazelles, in the district 

 where these were shot, were of the same kind, so that they conld 

 not be said to be abnormalities ; that it was quite possible for the 

 animal to be unknown to science, as few sportsmen had ever shot 

 before in that region ; that the specimens sent, two males and a 

 female, were much above the average in size, thotigh still finer 

 ones had been seen ; and that the ordinary Gazella granti of the 

 Athi plains and Kilimanjaro was unknown there. This Gazelle 

 was known as the " Biza " by the natives, who w^ere Wanyumwesi.

The colour of this Gazelle appeared to agree in all respects 

 with that of the typical form of G. granti, having the undivided 

 white rump-patch, the obsolete lateral bands, and the narrow but 

 distinct pygal band of that form*. The fur was somewhat more 

 wavy than in ordinary specimens. 



Besides those seen by Messrs. Roberts and Blaine, two heads 

 presenting similar characters had been obtained by Herr Oscar 

 ^^eumann in the Loita Mountains, on the boundary of British 

 and German East Africa, but had been not unnaturally regarded 

 by him as abnormalities f. 



In &p)ite of the very unusual nature of the distinguishing charac- 

 ters of this Gazelle, and its identity with Gazella granti in other 

 respects, Mr. Thomas thought that the number of examples that 

 had now been recorded, and the fact that this type alone inhabited 

 certain districts and had never been found elsewhere, necessitated
