434 REPORT OF THE HARVARD AFRICAN EXPEDITION 
suggests the division of the genus into three species; H. granulosus, E. oligar- 
thra Diesing, 1863 (Synonym: £. cruzi Brumpt and Joyeux, 1924), and £. 
longimanubrius. E. oligarthra was found in two species of Felis, F’. concolor and 
F. yaguarundi; while Brumpt found LZ. cruzi in an agouti (Dasyprocta agoutt) , 
from Brazil. E. longimanubrius was described by Cameron as a new species 
from a Cape hunting dog (Lycaon capensis). 
Pathological lesions of wart hogs have not been commonly reported. Fox : 
has recently cited two cases of cerebral affection relating to the pituitary body 

No. 363. — Camera lucida drawing of cysts in different stages of 
development, and granddaughter cysts in which inverted suckers 
and hooklets are visible 
of the northern wart hog, Phacochoerus africanus. In both cases there was 
bleeding from the nose prior to death. While no tumor formation was present, 
Fox assumed that simple enlargement of the pituitary might cause sufficient 
congestion for forced rupture of the vessels, and haemorrhage into the nose, 
pharynx, and cranial sinuses. 
Stunkard * has recently noted the occurrence of the trematode Gastrodiscus 
aegyptiacus (Cobbold, 1876) in the intestine of the wart hog, Phacochoerus afri- 
canus.
