NIGHT APES. 467 



turc. It sometimes gives a guttural, short, and rapidly-repeated 

 bark. 



There are several species of night monkeys with very simi- 

 lar habits. 



It is difficult, except when they are in captivity, to obtain 

 a correct idea of the habits of these interesting little animals, 

 — though, of course, when they are tamed, they must abandon 

 some of those they possessed in a state of nature. Of their 

 dispositions, however, a very fair notion may be formed from 

 the way they behave when in captivity. The above descrip- 

 tions refer only to a few of the numerous species of monkeys 

 which exist in the South American forests, but as t}-pical 

 forms have been selected, a tolerable idea of the whole may 

 be obtained.
