M. DB RoTHSCHiBD has criticised (1. c. 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. 



Phacochserus delamerei Lonnberg.

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. A. Sjogren 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 XII) exhibits the 

 characteristics which the present author has pointed out as typical for Phacochmms 

 delamerei (1. c. 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 (PI. XII). The length of this 

 portion is only 11,3 "/o of the upper length of the skull (resp. 10,5 % 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 7o of the upper length of the skull thus a httle more than in the types viz. 

 11,9 7o, and 11,570. The interorbital width is 36,6 7o of the length of head. This is 

 a little more than in the types viz. resp. 33,o °lo, and 34,7 7o but this difference is not 

 great enough to speak against the identity with Ph. delamerei 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.
