THE GERENUK OR WALLERS GAZELLE 281 



This antelope, first described by the late Sir V. Brooke on the 

 evidence of a flat skin, is in the habit of raising itself on its hind-legs 

 when browsing, and is thus enabled to reach boughs at a very con- 

 siderable distance above the ground. 



Mr. Oscar Neumann pointed out in 1899 that the Somali and 

 Abyssinian gerenuk (Lithocranius walleri s lateri] is somewhat different 

 from the East African or typical gerenuk. The northern form is 

 larger, with finer horns, a longer neck, a less rufous colour, and lacks 

 the black knee-tufts, while the white markings of the tail are also 

 different. The Somali gerenuk has been considered a distinct species, 

 but is best regarded as a local race or sub-species.
