The members of this genus, which are often kept in captivity 
as pets, are very small animals, covered with thick and silky 
fur, and having bushy tails, equal to or even exceeding the 
length of their bcdy. The head is round, the eyes large and 
watchful, the face short and nude, and often abundantly 
whiskered. ‘The mouth is large; the ears also large and often 
fringed, and the neck sometimes clothed, with long hair. 
They are distinguished from the Tamarins (J/idas) by having 
their upper incisor teeth long, narrow, and protruding outwards 
and forwards ; the incisors of the lower jaw are also very long, 
and its canines small and shorter than the incisors, both being 
protrusive, as among the Lemurs. The cranial region of the 
smooth skull is conspicuously large in comparison with its 
facial portion, but the cerebrum shows a low type of organisa- 
tion, and indicates a small degree of intelligence in its posses- 
sor; it is smooth and almost devoid of convolutions; the 
cerebrum, too, unlike that of the Lemrordea, completely covers 
the cerebellum. The orbits are large, and almost completely 
walled in from the temporal depression behind. The stomach 
in form resembles that found in the higher groups, but its 
orifices for the entrance and exit of food are nearer to each 
other than in any of the other American Monkeys. 
The female produces two or three young at a birth, instead 
of one, as is the general rule among the Axthropoidea. The 
species vary much in coloration, and some of them resemble 
the Lemurs in being ring-tailed.
