The following measurements of the skull of this specimen are recorded for 

 comparison with other species. 



Length of skull mesially from occipital crest to tip of premaxillaries 325 mm. 



Basioranial length 263 » 



Width of parietal flat area 42 » 



Least interorbital width 119 » 



Greatest zygomatic width 197 » 



Length of the postorbital portion of the skull 36 » 



From these measurements may be seen, as well as from the percentages quoted 

 above, how widely Fh. delamerei differs both from the broad-headed Ph. massaicus, 

 and the long-headed Ph. celiani. 



When speaking about this last species I take the opportunity of discussing a 

 question about the identity of Ph. celiani Cretzschmar, and Ph. haroia Ehrenberg, 

 which I have not been able to settle before, but for the solving of which I have 

 now received some material. The Swedish Missionary Rev. Mr. K. Roden has kindly 

 procured a fine skull of a Wart-hog boar from Gheleb in Eritrea. This place is 

 situated only about 75 kilometres northwest from Arkiko which is the type locality 

 of tPh. haroia^. It appears thus most probable that the same kind of Wart-hog 

 shall be found at these two not very distant localities. 



The male skull from Gheleb measures mesially from occipital crest to tip of 

 nasals 391 mm. and has thus very nearly the same length (viz. 388 mm.) as an 

 Abyssinian skull of Ph. celiani in Brit. Mus. Nat. Hist. The length of the postorbital 

 portion of both skulls is the same viz. 60 mm. The width of the parietal flat area 

 is a little greater in the skull from Gheleb viz. 32 mm., but it can nevertheless be 

 termed narrow as it is only about 8,3 "/o of the length of the skull. The interorbital 

 width measures 123 mm. that is about 31,4 "Iq of the upper length of the skull, while 

 the same percentage for the Abyssinian skull is nearly the same viz. 31,7 "/o. There 

 can thus be no doubt that the Wart-hog from Gheleb is identical with the Abyssi- 

 nian Ph. celiani, and accordingly it may be concluded that Ph. haroia is fully syno- 

 nymous with Ph. celiani. 



For future comparison a few measurements of a female skull of Ph. celiani 

 from Gheleb may be added: 



Length of skull mesially from occipital crest to tip of premaxillaries 335 mm. 



Width of parietal flat area 33 » 



Least interorbital width 103 » 



Length of postorbital portion of skull 55 » 



The parietal flat area is thus in the female a little broader than in the male. 



Phacochaerus africanus subsp. 



Wart-hogs are or have been not uncommon on the plains around Nairobi. As 

 I, however, had very little opportunity of shooting there, I did not obtain any ma-
