After careful study of the common East African wart-hog skulls 
enumerated above I quite agree with Heller that it is apparently 
impossible satisfactorily to separate the animal into races over all 
this region. There is much genuine individual variation in the 
skulls, and the characters so far pointed out by which a form from 
southern British East Africa might be distinguished are far from 
satisfactory. 
From the accompanying table of measurements of 24 male wart- 
hog skulls (p. 53) it will be seen that the relative proportions used by 
Doctor Lénnberg as the principal characters in separating massaicus 
from #xliani prove to be too inconstant and unreliable in this case 
for systematic purposes. The skull of true xliani from Zulla, Abys- 
sinia, misusured by Lénnberg at the British Museum,' had a total 
1 Proc. ‘Zool. Soc. Takiot, 1908, p. 937.
