34 SIR VICTOR BROOKE CHAP. 



Contains an exhaustive account of the literary 

 history and synonymy of Nanotragus pygmeus, the 

 smallest of all the antelopes, and a comparison of its 

 characters with those of the allied species, illustrated by 

 a coloured plate and woodcut of the skull. 



On a New Species of Antelope living in the Society's 

 Menagerie. P. Z. S., 1872, p. 874. 



A previously unknown antelope from the Gambia, 

 described and figured under the name of Nanotragus 

 nigricaudatus. 



On African Buffaloes. P. Z. S., 1873, p. 474.

Exhibition of Skins, Skulls, and Heads of Cervus 

 antisiensis. P. Z. S., 1873, p. 518. 



On the Antelopes of the Genus Gazella and their 

 Distribution. P. Z. S., 1873, P- 535-

 of evolution offers a reasonable manner of accounting 

 for the present differentiation and distribution of the 

 group. For this purpose the literature of the extinct

 of Wagner, Falconer, Gaudry, Gervais, and Huxley are
