STRUCTURE OF THE GORILLA 229 



gave me a minute account of the appearance and habits of 

 a fourth kind, which I believe to be another species of the 

 gorilla. They claim that he is more intelligent and human- 

 like than any one of the others. They say that his supe- 

 rior wisdom makes him more alert and, therefore, more 

 difficult to find. He is said always to live in parts of the 

 forest more remote from human habitation. On my next 

 voyage I mean to hunt for this new species. 



The dental formula of the gorilla is the same as that of 

 man ; but the teeth are larger and stronger, and the canine 

 teeth are developed into tusks. One thing to be remarked 

 is the great variety of malformations in the teeth of this

 set of teeth, except in infancy. The cause of this defi-

The eyes of the gorilla are large, dark, and expressive, 

 but there is no trace of white in them. That part of the 

 eye which is white in man is a dark coffee-brown in the 

 gorilla. It becomes lighter as it approaches the base of 

 the optic nerve. The taxidermist or the artist who often 

 furnishes him with a white spot in the corner of his eye

 ture, but they are caricatures of the thing they mean to 

 portray. 



The ears of the gorilla are very small and lie close to 

 the sides of the head. The model of them is much like 

 the human ear. The lower lip is massive, and the animal
