226 PSEUDOGORILLA 
In their description of G. MAYEMA Messrs. Alix and Bouvier state 
that one of the most remarkable peculiarities of the species consists in 
the back being covered with very long and thick hair, quite contrary 
to that seen in other Gorillas which have this part bare or sparsely 
covered with short, worn hairs. I cannot say that these Frankfort 
specimens have any such character, for the hair appeared to be no 
longer on the back than on other parts of the body. But I should 
hesitate to separate these examples on that account. I made inquiries 
in Paris for the type of Alix and Bouvier’s species, but nothing was 
known of it or what had become of it. It is certainly not in the Paris 
Museum where one would most naturally look for it. 
The examples in the Frankfort Museum were members of one 
family, and were procured at the same time and place. The nest, 
placed in the branches of the tree was also secured and the baby lies 
in it, probably in the same position in which it was discovered. 
As there was no opportunity afforded for examining the unique 
type of G. MAYEMA, and as there are certain discrepancies in the type 
and the Frankfort examples, I cannot be absolutely certain that they 
are the same, and so have placed a ? mark after the specific name; for 
the genus has been founded upon the examples seen in Frankfort and 
not upon the description of Messrs. Alix and Bouvier. If eventually 
it is found that there is but one species, then the name at the head of 
this article will stand, but if it is proved that true mayema is a different 
species, the present form will have to take a new specific name.
