The Quicu, as this animal 
is 
called by 
the 
natives 
Brazil, is found in the Surinam district, and, no doubt, in 
other parts of Guiana, but appears to be most abundant in 
Brazil. It lives upon trees, and feeds upon small birds, 
insects, and fruits. During the day-time, like others of its 
group, it sleeps, having its body then rolled into a ball.
