The native country of this monkey is yet somewhat 

 uncertain ; but the best authorities record it as the 

 islands of the Indian Archipelago. 



With this species we close what was mentioned as 

 the first division of the Baboons, and enter upon the 

 second the Cynocephali of Cuvier. These, according 

 to the researches of the brother of this great naturalist, 

 consist of only six species, which are again subdivided 

 into two very natural sections. The one, with a con - 

 siderable length of tail ; the other, with the muzzle 

 swollen upon the sides, and in the adults raised into 

 coloured ridges, while the tail is a tubercle finished 

 by a tuft of hairs, and stands erect, appearing, from 

 the position of the coccyx, as if placed upon the lower 

 part of the back itself. 



The Cynocephali are all of large size, and indeed 

 exceed that of any of the quadrumanae, if we except 

 the adult orang-outang; their proportions combine 

 strength and activity, and their physiognomy fierceness 

 with intelligence ; while their dispositions are so fickle, 

 or so easily affected the transition from one passion 

 to another is so rapid, that they are never to be 

 trusted and the paroxysms of their rage are described 

 by F. Cuvier to be so great, that some have fallen vic-

 this group the active animal passions are developed
