The race of Bush Pig descibed above has been named the Kenia race because 
it evidently inhabits the forests of the Kenia plateau. On the northern side of this 
plateau the dry Somali-Galla countries are situated, and on”the southern side the 
open FEast African steppe. Both these surrounding countries do not offer suitable 
conditions of life for Bush Pigs, and the Kenia race appears thus to live in a certain 
isolation which may account for its differentiation. The geographically nearest race 
in the south east is P. ch. demonis (MAJOR) of Kilimanjaro which is easily recognized 
on its smallness and very narrow parietal area.! In the north the Abyssinian P. 
hassama (HEUGLIN) is a rather distant neighbour. This latter race is chiefly known 
from the first description,” but ForsYTH MaJsoRr has also published some notes and 
two figures of a skull. He points out as for this race especially typical characteristics 
the low canine apophysis, and »the elongation of the hinder part of the skull back- 
wards from the postorbital processes of the frontals».” These characteristics are also 
plainly shown in MaJor's figures, and prove the distinetness in these respects of the 
Abyssinian race from the one from Kenia. The present author has not had any 
opportunity of examining any boar skuli from Abyssinia, but an evidently female- 
looking skull has been obtained for this museum from Gheleb, Eritrea, through the 
kindness of Mr. K. G. RopÉnNn. The measurements of this skull have been recorded 
in the table above, side by side of those of the sow skull from Nairobi. From this 
may be seen that the posterior portion of the skull is broader with regard to several 
dimensions in the Abyssinian than in the Kenia specimen. The former is also some- 
what longer with regard to its postorbital extension, although this is less striking 
than in MaJor's figure of the boar skull. The nasals are more vaulted than in the 
Kenia specimen, and the anterior part of the zygomatic arch is much more gradually 
sloping towards the facial portion. 
The colour of the Abyssinian race is very different from that of the Kenia race. 
Two skins of P. hassama male and female obtained by Mr. K. G. RoDÉN at Gheleb 
have the snout and the upper part of the head behind the interocular region whitish. 
The whiskers and a streak below the eye are also white, the remaining part of the 
head blackish brown. Chin mixed with whitish. HEars, shoulders, hams, and feet 
blackish brown. Back and sides pale rufous somewhat mixed with blackish in the 
boar, still paler, partly buffish in the sow. The dorsal erest which does not extend 
over the posterior back, is whitish with hardly any, or few black bases to the bristles. 
Two little pigs of P. hassama from the same locality are pale rufous somewhat 
mixed with black. A whitish crest is developed over the withers and anterior portion 
of the back. Preocular region of head above and below blackish brown; ears and 
feet of the same colour which extends more or less up the legs. 
P. hassama is thus in all ages much paler than P. ch. kenice which latter with 
regard to its very dark colouration of the body more resembles P. ch. demonis.
