and discovered many new birds and mammals, which were subsequently 
described in his various works. Amongst the mammals was the present 
species of Gazelle, which he met with only “on the bushy plains round Ain- 
Saba from 3000 to 5000 feet above the sea-level, in small families of from 
three to six individuals.’ In his original description Heuglin called this 
Gazelle Antilope melanura, but subsequently altered its specific name to 
*“ tilonura,’ there having been already an Antilope melanura of Bechstein, 
which term is, however, a useless synonym of the Oribi (Ourebia scoparia). 
We have not been able to discover what the term “ télonura” means, but 
follow the change, which has been adopted by Sir Victor Brooke and other 
authors. 
Little more, we regret to say, can be told of this beautiful species, which 
is readily distinguishable amongst its congeners by its broad black lateral 
stripe and lyre-shaped horns with incurved points. Sir Victor Brooke gave a 
figure of it from a stuffed specimen in his own collection to illustrate his 
article on the Gazelles in the Zoological Society’s ‘ Proceedings’ for 1873. 
Our figure (Plate LX VI.), which was prepared by Smit under the direction 
of Sir Victor Brooke, was probably taken from the same specimen, now in the 
British Museum, to which it has been presented by Sir Douglas Brooke. It 
was obtained in Bogosland by Essler about 1872. Four other examples of 
this Gazelle procured at the same time by the same collector are also in the 
National Collection. From two of these the accompanying illustrations of 
the head and horns (figs. 71 & 72, p. 160) have been prepared by Mr. Smit.
