PECULIARITIES OF THE SKULL 223 



basin, but on the opposite side of the lake. The facial 

 bones of No. 6 show that he had received a severe blow 

 early in life ; but the fragments had knit together, and 

 the effect could not be seen in the face of the ape while 

 alive. 



No. 8 is the skull of a large male from Lake Izanga, 

 which is on the south side of the Ogowe River, more than 

 a hundred miles from the coast. This is one of the three 

 centers of population mentioned. I do not know the his- 

 tory of this specimen. It was presented to me by Mr. 

 James Deemin, an English trader, with whom I traveled 

 many days on the Ogowe River, and who extended to me 

 many courtesies. 



No. 5 is the skull of an adult female. By comparing it 

 in profile with No. 6, it will be seen that they resemble each 

 other closely, except that the muzzle of the latter projects a 

 little more, and the curvature of the skull across the top is 

 less ; but the transverse distance is a little greater. Nos. 

 2, 3, 4, and 5 are females ; the others are males. 



While this series is not complete in either sex, it is 

 an excellent one for comparative study. I do not know 

 whether or not the heads of those with the crests were the 

 same color as No. 6, but the ntyii, which I have mentioned 

 as possibly a new specimen of the gorilla, does not have 

 this crown of red. His ears are also said to be larger than 

 those of the gorilla, but smaller than the chimpanzee's. He 

 is reputed to grow to a larger size than either of them. 

 The skin of the gorilla is a dull black or mummy color over 

 the body ; but over the face it is a jet black, quite smooth 

 and soft. It looks almost like velvet.
