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.
