11. Ou a new Antelope of the Genus Hippotragus. 

 By Oscar Neumann.* 



[Received November 1, 1898.] 



I propose to designate a new geographical form of the Roan 

 Antelope {Hippotrmjus equinus) from East Africa by the name 

 of:— 



Hippotragus rufo-pallidus, sp. nov. 



General markings as in H. equinus, but the colour without any 

 brownish or greyish tints, being of a pale reddish, lighter in some 

 specimens and more red in others, but never of a dark red as in 

 the West-African form.^ 



The legs of M. rufo-pallidus are of a dark reddish colour, the 

 oldest specimen in my collection having black markings on the legs. 

 The base of the tail is black, this colour extending to the hind part 

 of the back. The ears are tufted, but the hairs are not so long as 

 in if. haJceri. 



Hah. German and British East Africa. 



1 believe that all the Eoan Antelopes mentioned from German 

 and British East Africa (Uganda Protectorate), also that which 

 Mr. Hinde shot at Machako's (cf. de Winton, P.Z.S. 1898, p. 127), 

 belong to this species. I am, however, of opinion that the Antelope 

 is very rare in these countries, as I met with it only on one 

 occasion during the two years of my travels in East Africa. This 

 was a herd, out of which I shot five specimens, unfortunately all 

 females, on the 24th September, 1893, on the upper part of the 

 Eiver Bubu, about halfway between Irangi and Mount Gurui. 

 When approached the herd did not make off at full speed but 



' Communicated by the Secretary. 



2 I am quite of the opinion of Ilerr Matschie that it is impossible to attribute 

 the Anfilope kob of Erilebeu to a Hippotragus, as it must be either an Adcnota 

 or a Bubalis. The original French description of Buffbn indicates a Bubalis, 

 ■while the plate represents an o\A Adenota kob, and the plate oi Antilope kob 

 depicts a young specimen of the same animal.
