HaMts. — This species is not at all uncommon in menageries. 

 Numerous specimens have from time to time been exhibited 

 in the Zoological Gardens in London. Little is known, how- 

 ever, of the habits of the Moustached Monkey in its native 

 forests. In captivity it is intelligent, lively, and good-tempered, 

 but very shy. Its delicate constitution cannot resist the rigours 

 of our climate for any length of time.
