136 FINAR LONNBERG, MAMMALS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION ETC. 
Hylocherus meinertzhageni THomas. 
Tuomas: Proc. Zool. Soe., 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 Forest-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 (Pl. 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 Sanppack 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 Hylochwrus meinertzhageni was obtained 
from Nandi, and from the same region MAuRICE DE RotscHiLtD and H. NEUVILLE 
have described several specimens of both sexes.” These authors describe their speci- 
mens, and figure the head of a sow (lI. c. p. 144) with »deux taches blanches ou 
d'un blanc jaunatre, lune & la commissure des lévres, l'autre au dessous de ]’oreille, 
& Particulation de la machoire» (1. c. p. 146). In an adult sow of Forest-Pig, obtained 
through Rowtanp Warp 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 RoruHscurLpD and NEUVILLE write 
about the specimens from Nandi »la gorge, la poitrine, le ventre et les parties internes 
des membres, en un mot toutes les parties inféro-internes de la peau sont parsemées 
de soies blanches» (I. ¢. 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 (l. 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. WoopHoUsE 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 
' ©. W. Woopuouse (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.
