different species. The hair ofthe female Yarke is decorated near the tip with 
several rings of a rusty brown colour, while the hair of the male is entirely 
devoid of these marks. 
The natural food of these animals is said to consist chiefly of wild bees and 
‘their honeycombs. Perhaps the long furry hair with which the Sakis are 
covered may be useful for the purpose of defending them from the stings of 
the angry insects. On account‘ of the full and bushy tail with which the 
members of this group are furnished, they are popularly classed together 
under the title of Fox-tailed Monkeys. 
THE term “ Nyctipithecus,” or Night-monkey, which is used as the generic 
title of the DOUROUCOULLI, refers to its habits, which are more strictly noctur-

hand of its captor drag it from its concealment. During sleep, it gathers all 
its four feet closely together, and drops its head between its fore-paws. It 
seems to be one of the owls of the monkey race. 
The food of this Douroucouli is mostly of an animal nature, and consists 
chiefly of insects and small birds, which it hunts and captures in the night 
season. After dark, the Douroucouli awakes from the torpid lethargy in 
which it has spent the day, and, shaking off its drowsiness, becomes filled with 
life and spirit. The large dull eyes, that shrank from the dazzling rays of the 
sun, light up with eager animation at eventide; the listless limbs are instinct 
with fiery activity, every sense is aroused to keen perception, and the creature 
sets off on its nightly quest. Such is then its agile address, that it can capture
