This seems to be a mountain species dwelling at a high elevation, and 

 possesses a coat capable of affording protection against cold. The hair 

 is very long and thick, quite an unnecessary covering for an animal 

 dwelling in a hot country. The white band on the back is much 

 narrower and includes much less space than the similar coloring 

 does in other species. Both the females and young are also clothed 

 with long hairs, but in their case the coloring is a uniform black.

This is not a very large Gorilla, but is remarkable for its nearly 

 uniform black color, differing in this respect from the other races. 

 The white tips to the hairs between the shoulders are not very dis- 

 tinct, and merely give a slight gray tint to the black hairs, and the 

 brown thighs are also not very strong in color in contrast to the black. 

 The specimen is an old male with the teeth much worn. 



The skull has a long facial region and a long braincase, with a 

 low crest on the occiput ; the braincase is wide and rounded ; and the 

 lateral occipital bony expansion is not very wide and but slightly over- 

 hangs the occipital region. Zygomatic arches are not widely expanded 

 and lie parallel to the skull. The teeth are very large, all the molars 

 nearly uniform in size.
