Hylochcerus meinertzhageni Thomas. 



Thomas: Proc. Zool. Soc, 1904, p. 193. 



When the Expedition passed through the upper forest belt of northeastern 

 Kenia where clumps of bamboo were mixed with the trees at an altitude of approxi- 

 mately 2,700 m. a skull of an old and very big boar of Torest-Pig was picked up 

 by Mr. Jansson, and close to it a few minutes later one of the boys found the lower 

 jaw as well. It was no doubt a specimen which had been trapped by the Wando- 

 robbos in one of their ingenious pitfalls, of which quite a number was seen during 

 the march. The tusks and incisors were missing, probably broken out by the wild 

 huntsmen, but otherwise the skull (PI. XI) was complete with exception of the ex- 

 treme tips of the nasals and the prenasal bone. In this region spoors and droppings 

 of Forest-Pig were very numerous, the latter closely resembling those of domestic 

 Hogs, although larger. In some places the Forest-Pigs had rooted up the ground,* 

 and it appears that these animals are quite common in this belt of mixed bamboo 

 and forest on the upper slopes of Kenia even on its northeastern side. I was also 

 told by Mr. & Mrs Sandback Baker of Nairobi who kindly presented me a skull 

 of an adult but not old sow of this species, that formerly these pigs had been found 

 in the lower forest regions as well, but their regular haunts are no doubt the lower 

 bamboo and upper forest region. The type of Hylochcerus meinertzhageni was obtained 

 from Nandi, and from the same region Maurice db Rotschild and H. Neuville 

 have described several specimens of both sexes. ^ These authors describe their speci- 

 mens, and figure the head of a sow (1. c. p. 144) with »deux taches blanches ou 

 d'un blanc jaunatre, I'une a la commissure des levres, I'autre au dessous de I'oreille, 

 a I'articulation de la machoire^ (1. c. p. 146). In an adult sow of Forest-Pig, obtained 

 through Rowland Ward from Mau, these whitish spots are entirely absent. The 

 bunches of bristles mentioned by the authors quoted as forming the spots are well 

 developed, but are entirely black. In a similar way the specimen from Mau has not 

 a single whitish bristle on its lower side, whereas Rothschild and Neuville write 

 about the specimens from Nandi »la gorge, la poi trine, le ventre et les parties internes 

 des membres, en un mot toutes les parties infero-internes de la peau sont parsemees 

 de soies blanches* (1. c. p. 147). It is of course impossible to say whether these 

 differences are constant or not, and in the male specimen figured by the authors 

 quoted (1. c. PL I) these spots are not visible. Unfortunately I have not had the 

 opportunity of seeing any skin of Forest-Pig from Kenia. C. W. Woodhouse says 

 about the Forest-Pig of Mau: » there is usually a white tuft of hair in the sow and 

 young on the horizontal tubercle of the face, and this remains in the boar as a few 



' C. "W. Woodhouse (conf. below when writing about the habits of the Forest-Pig of Mau says that it 

 does not root. It is thus possible that the »rootings» seen by me were products of Bush-Pigs, although there 

 were spoors and droppings of Forest-Pigs at the place.
