M. DE ROTHSCHILD has criticised (1. ec. 142) reports about the Forest Pig in 
which this animal has been compared in size with a zebra. The latter animal stands 
of course higher on the legs but in bulk and weight of body an old boar of Forest- 
Pig may not be very much smaller.

When the present author named this new species of Wart-hog and based the 
description on two skulls in British Museum Nat. Hist. it was not known with full 
certainty where these skulls had been collected, but it was presumed that they were 
from Somaliland. Last spring (1911) when I had the pleasure of meeting the donor of the 
skulls mentioned, Lord DELAMERE in Nairobi, he told me that they probably were 
from the country north of Guaso Nyiri which by the present expedition has been 
proved to be inhabited by a fauna agreeing with that of the Somaliland to great 
extent. 
Wart-hogs were by no means numerous in those parts of the Guaso Nyiri district 
which I visited. I saw only once a sow with two half-grown pigs in the thornbush- 
country near the water-place Njoro. I shot this sow through the chest, but she escaped 
in the bushes, although severely wounded and very much bleeding. 
Some time later Mr. Å. SJÖGREN shot an old sow of the same kind on the 
northern side of Guaso Nyiri and allowed me to keep the head for the collection of 
the Expedition. This specimen measured about 112 cm. from snout to vent and 
about 65 cm. in height at withers. The skull of this female (Pl. XTI) exhibits the 
characteristics which the present author has pointed out as typical for Phacocherus 
delamerei (1. ce. p. 938). There are no incisors in the upper jaw, and the premaxil- 
laries are so very thin that they could not possibly hold any alveoles for incisors 
just as in the type specimens. In the lower jaw four rudimentary incisors are to-be 
seen. The nasals are rather flat, not forming any ridge behind. The shortness of 
the postorbital portion of the skull is quite striking (Pl. XII). The length of this 
portion is only 113:3"/o of the upper Jength of the skull (resp. 10,5 ”/o and 10,9 "/o in 
the type specimens in British Museum Nat. Hist. The width of the parietal flat 
area is a little greater than the length of the postorbital portion of the skull. It is 
12,9 ”/o of the upper length of the skull thus a little more than in the types viz. 
1139”/o, and 11,5”/o. "The interorbital width is 36,6 "/o of the length of head. This is 
a little more than in the types viz. resp. 33,0 "/o, and 34,7 /o but this difference” is not 
great enough to speak against the identity with Ph. delameret especially as other 
important characteristics fully agree. It is thus stated that this species inhabits the 
thornbush country north of Guaso Nyiri and may from there extend towards So- 
maliland,
