This is a large Chimpanzee belonging to the bald-headed group, 
with a back much lighter than the rest of the body and limbs, and 
comes from the same district in which the large gray Gorilla ex 
MoxseE, Cameroon, is found. The skull is short and rather heavy, 
with the facial region about equal in length from the anterior edge of 
the orbital ridge to the occiput. The braincase is broad and rounded, 
and the rostrum is very broad for its length, the greatest width being 
at the canines. The orbital ridge is straight, but with a slight depres- 
sion behind and overhangs the orbits only slightly. The orbits are 
round, and the narial opening is large, heart shaped and very broad 
anteriorly. The palate is broad, equal in width throughout its length 
and the teeth are moderately large, with the tooth rows straight. 
Pterygoid fossa short and broad and basioccipital quite broad. Its 
place seems to be near P. CALvus.
