This is the only specimen of this form I have seen. Slack only 
exhibited a cast of the head when he conferred the above name, but 
nothing whatever is known of his type or what has become of it. It 
is not in the Collection of the Philadelphia Academy of Natural 
Sciences, and I could find no record that it had ever been there. 
The two following specimens are in the Berlin Museum, but not yet 
characterized by Herr Matschie. The large gray Gorilla may represent 
an old individual in the pale pelage of G. g. matschie, or G. GORILLA; 
but the wholly black example is possibly a distinct form, as it is the 
only specimen of that color known. 
GORILLA GORILLA ? 
Locality. Between the rivers Dume and Bumba near Mokbe, 
southern Cameroon near Congo boundry. Specimen in Berlin Museum.
