392 SWINE GROUP 



boars, the upper ones forming a pair of convex crests projecting high 

 above the plane of the nose, while the pair on the roots of the tusks 

 reaches to that plane. The upper surface of the skull in advance of 

 the (post-orbital) processes at the hind border of the eye-sockets is 

 relatively narrow. Although the southern representatives of the 

 species have the skin black, with grey, brown, or blackish hairs, some 

 of the eastern, and probably also the western, races are reddish in 

 colour. In adult boars the face is dirty white, while the ear-tufts and 

 the dorsal crest are black. 



According to the foregoing list given by Mr. Rothschild, P. 

 diocropotamp.s is typically a western species, extending from the west 

 coast to Angola. I have, however, not seen a description of a western 

 representative of the species ; and in the Proceedings of the Zoological 

 Society for 1906, p. 632, Mr. Rothschild himself writes of this species 

 as being typically South African. 



According to the latter view, the bush-pig of the Cape does not 

 require a separate racial name. In this race the colour is very 

 generally grey ; but years ago Sir Andrew Smith (who may have 

 been referring also to some of the more northern races) remarked 

 that " scarcely any two specimens of the species exhibit the same 

 colours ; some are a brownish black variegated with white, and others 

 are almost entirely of a light reddish brown or rufous tint, without 

 any white markings ; indeed, such are the varieties that it is scarcely 

 possible to say what are the prevailing colours." The ears, which are 

 whitish internally, have black margins and tufts. 



In the Lake Mweru district and the south-west portion of 

 Nyasaland the Cape bush pig is replaced by a reddish race (P. c. 

 nyascB). These Nyasa bush -pigs agree, however, with the present 

 species in the characters of the skull, and also differ from the red 

 river-hog by the absence of black on the face of the adult boar, and 

 the black ear-tufts and crest. The colour is much redder in immature 

 than in fully adult specimens. 



To the Kilimanjaro race Dr. Major (who also named the Nyasa 

 bush-pig), in the Zoological Society's Proceedings for 1897, p. 367, 

 has given the name P. c. dcEiiionis ; the title dceinonis referring to the 

 habitat of the race, the etymology of Kilimanjaro being kilima, a 

 mountain, and njaro, a demon. This race was named on the evidence 

 of the skull and skin of a female. The latter is covered with long 

 blackish-brown bristles ; while the skull agrees with that of females of 

 the present species in the flatness of the posterior nasal region, as 

 well as in the complexity of the molar teeth, although in the shortness
