212 : GORILLA 
GEOGRAPHICAL DISTRIBUTION OF THE SPECIES AND SUBSPECIES. 
It cannot be said that the dispersion of any species or race of 
the described Gorillas is definitely known at the present time, as the 
limited number of specimens in the various museums is too small to 
give any idea of the range, the majority giving us merely the type 
locality, and beyond this affording little information. Beginning with 
the species longest known, G. GoRILLA is found in the Gaboon, not going 
according to Du Chaillu south of Sette Cama, but how far it ranges 
into the interior is not known. Du Chaillu obtained specimens on the 
Fernand Vaz and Ofoubon Rivers. G. g. castaneiceps from the 
Fernand Vaz in French Congo, in the Kamma country, is by no means 
established as a distinct race. Most probably this is the same as G. 
GORILLA. In Cameroon we have at Yaundi, G. g. matschie, and at 
Lobo-Mundung G. g. jacobi was found. All these from South 
Cameroon. In the north, at Oboni, G. g. diehli was found. On the 
east coast in the German Protectorate, at Kirunga G. BERINGERI was 
taken.
