The type is a young male, and is very much darker than the fine 

 living animal in the Zoological Garden at Kyoto, which came from

 only species of Monkey in the Island of Formosa. It affects rocks 

 and declivities that overhang the sea, and in the solitary caverns makes 

 its abode. On the treeless mountain in the S. W. called Ape's Hill, 

 it was at one time especially abundant, but has since almost entirely 

 disappeared. About the mountains of the north and east it is still 

 numerous, being frequently seen playing and chattering among the 

 steep rocks, miles from any tree or wood. It seems to be quite a rock- 

 loving animal, seeking the shelter of caves during the greater part of 

 the day, and assembling in parties in the twilight, and feeding on 

 berries, the tender shoots of plants, grasshoppers, crustacea and
