1904.] THE HON. W. ROTHSCHILD ON A NEW ANTELOPE. 229 



Sir Harry Johnston that Doggett's ' Shaw-le ' Antelope was also 

 described to him by Balega people from the west of Lake Albert, 

 and struck him from the description (if there is any fact at the 

 bottom of these stories) as being very similar in appearance to a- 

 Nilghai. Sir Harry also thought that the large Forest ' Pig ' of 

 which Sir Henry Stanley had heard, and which was also mentioned 

 to himself, might possibly be the Dwarf Hippopotamus which 

 occurs in the forests of West Africa. 



Prof. E. A. Minchin, F.Z.S., exhibited and made remarks upon 

 a specimen of the Spider Ileteropoda regia (Fabr.), which had 

 been captured at University College, London. This Spider had 

 n. very wide distribution, which was probably due to its being 

 carried by the wind during its younger stage and also by ships. 



The following papers were read : — 



1. Description o£ a new Antelope. 

 By Hon. W. Rothschild, D.Sc, F.Z.S. 



[Received Feljruaiy 15, 1904.] 



Cephalophus nyas^ defriesi. 



This small buck is evidently a local representative of C. nyasce 

 (described by Mr. 0. Thomas in the Ann. &. Mag. Nat. Hist, 

 ser. 7, vol. ix. p. 58), and is, like that form, at once distinguish- 

 able fi'om all others of the C. ^nonticola- group by the exti-eme 

 length and attenuation of the skidl, and the produced hoofs 

 necessary from the marshy ground forming its habitat. 



It diffei-s from C. nyasce in the greater extent of red on the 

 flanks and thighs and more intensely rufous legs. The belly is 

 much more extensively white, the greyish brown of the uppei' 

 surface is paler, and the light streak on the side of the face and 

 over the eye broader and more rufous. 



Described from 2 c? and 1 $ procured by Mr. Louis de Fries, 

 after whom it is named. 



Rah Northern Rhodesia. 1 (^ from Itambe, between Lakes 

 Mweru and Tanganyika ; 1 c? , 1 $ , Kafue River, near borders of 

 Barotse-land. 



Mr. de Fries gives me the following notes : — " This small 

 Antelope is called Kampalanga by the Swahili and Walambn, 

 n.atives. It lives in the swamps in company with Situtunga, 

 (Tragelaphus selousi). Its food consists chiefly of the leaves of 

 the rubber-vine, and I have never found examples weighino- 

 more than 9 lbs. When pui-sued these animals take refugt! in 

 the swamps ^nd even deep water."
