SABLE AND BEATRIX ANTELOPES 



horns of some length, present in both sexes, and of a longish 

 tail. They are all African in range. 



The type genus Hippotragus has its horns placed above the 

 orbits ; they are not twisted, but curved backwards. There are 

 three species in the genus. Of these the best known is H. niger, 

 the beautiful Sable Antelope. Its general colour is a rich, dark, 

 glossy brown with white stripes on the face, and with a white 

 belly. The other species are the Eoan Antelope, H. equinus, and 

 the Blaaubok, H. leucopkaetts, of which the last specimen was 

 probably killed in 1799. 1 



The genus Oryx (chiefly African, but also Arabian and Syrian)

also contains a number of species, which are fairly familiar through 

 the fact that several of them are always on view in the Zoo- 

 logical Society's Gardens. The genus differs from Hippotragus 

 in that the horns, present in both sexes, are placed behind the 

 orbits, arid slant backwards in a line with the face. They are 

 aunulated. The Leucoryx (0. leucoryx) is of a pale colour, but
