1 62 ANTELOPES 



In the Ituri Forest it is represented by a race distinguished by- 

 slight variation in colour, especially on the under-parts, to which 

 Baron Maurice de Rothschild and Mr. H. Neuville (Compt. Rend. Ac. 

 Paris, 1907) have given the name C. cequatorialis bakeri. 



THE BLUE BUCK OR BLUE DUIKER 



(Cephalophus monticola} 



Blaauiv-bok, CAPE DUTCH ; Ipiti, ZULU 

 (PLATE vi, fig. 6) 



This well-known species, which has many scientific aliases, agrees 

 in size and the characters of the horns with the black-backed duiker, 

 and in colour with Maxwell's duiker, except that the limbs from the 

 knees and hocks downwards are bright rufous. It is the earliest 

 named of the blue duikers, dating from 1 8 1 1 ; and it is possible that 

 melanorheus, maxwelli, cequatorialis, and nyasce should be regarded in 

 the light of its local races. 



The species is widely distributed in south-eastern Africa, the 

 Umgozy Forest in Zululand, Eland's Poort, and Galgebosch, in the 

 Uitenhage Range, being well-known localities in which it swarms. 

 On account of slight colour-differences, the Zululand form has been 

 distinguished as Cephalophus monticola caffer. 



The following excellent account of the habits of this species was 

 communicated by Mr. F. Vaughan Kirby to the Zoological Society's 

 Proceedings for 1899 : 



" Even in the densest bush, the spaces underneath to a height of 

 two feet from the ground are comparatively clear, hence the little blue 

 duiker, or blue-buck, as it is generally called, moves about in what to 

 him is practically open bush, in which objects are visible at a con- 

 siderable distance : thus the stooping, struggling form of the stalker 

 worming a passage through an opening two feet square in an 

 unyielding wall of thorns, or striving to free himself from the too firm 

 embrace of a network of ' wacht-een-beetje ' bushes, cannot fail to 

 attract attention long before the little grey watcher, standing motionless 

 in the shadows, has been discovered. 



"At the bush-drives so common in the Colony, blue-buck are 

 seldom turned out ; they will keep such dogs as have not learned
