Habits. The Common Marmoset is an inhabitant of the 

 forests, feeding chiefly on fruits and insects. It is very sus- 

 ceptible to cold, and lives but a short time when removed from 

 the tropics, unless extreme care be taken. Mr. Bates, the author 

 of " The Naturalist on the River Amazons," states that when 

 in Para, he counted in a short time thirteen different species 

 of Monkey in semi-domestication in the city, either at the 

 doors or windows of houses, or in the native canoes. Two 

 of them he did not meet with afterwards in any other part of 

 the country. One of these was the well-known Hapale jacchus, 

 a little creature resembling a Kitten, banded with black and 

 grey all over the body and tail, and having a fringe of long 

 white hairs surrounding the ears. It was seated on the shoulder 

 of a young mulatto girl as she was walking about the street, 

 and he was told that it had been captured in the island of 

 Marajo.
