times the head and neck greyish-white, or the head, neck and 
ear-tufts black, or the head alone white. 
Distribution—Island of Marajo, at the mouth of the 
Amazon. 
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.
