NO. 22 LARGE MAMMALS FROM EQUATORIAL AFRICA — HELLER 3 



of elevation in the parietal or lambdoidal crests which are on the 

 same level as the interorbital region, the narrowness of the choanae 

 posteriorly and the smaller size of the tympanic bullae. 



The type, unfortunately, is an immature skull in which the last 

 molar is just erupting and has all of the maxillary sutures still evi- 

 dent. Skulls of this age from the highlands of British East Africa 

 show a much narrower, shorter and more elevated parietal region. 

 In the flatness of the interorbital region and in the general shape of 

 the post-orbital part of the skull the type resembles the skull of 

 Phacochccnts dclamcrei more closely, but differs from this species 

 as do all the africanus group by the presence of well-developed upper 

 and lower incisors, and roofed over choame. The skull is large for 

 the age it represents which would indicate a large adult size for this 

 race. 



Measurements. — Measurements of the skull: greatest length from 

 lambdoidal crest to tip of nasal bones, t,j$ nun. ; condylo-basal length, 

 302; zygomatic breadth, 181 ; least orbital width, 112; width of 

 parietal constriction, 76; least width of parietal flat area. 45 ; median 

 length of post-orbital portion of skull from orbit to lambdoidal crest, 

 68; maxillary constriction of skull across first premolar, 51 ; length 

 of premaxilke beyond base of tusks, 57. A series of some fifty skulls 

 of warthogs are in the National Museum from the Loita Plains, 

 Kapiti Plains, and Uasin Gishu Plateau which apparently represent 

 the Abyssinian race, eeliani. This large series shows considerable 

 variation in shape of the post-orbital portion of the skull, but the 

 extremes in width and length do not equal the specimen from the 

 Lado Enclave described as the type of bufo. A specimen of the same 

 age as the type from the Loita Plains has a skull length of 350, width 

 of the parietal constriction 60, and length of post-orbital portion 52. 



Remarks. — The type specimen was collected on the shores of a 

 small pond near Chief Sururu's village in the vicinity of Rhino I lamp. 

 It had been killed by a lion the night previous to the arrival of Colonel 

 Roosevelt's hunting party, and the head was the only portion which 

 remained uneaten. Warthogs were rare in the La<lo Enclave, less 

 than a score being seen by the members of the Smithsonian African 

 expedition during a month's sojourn in the upper Nile district.
