nostrils are wide, and divided by an unusually large
cartilage. It is furnished with large jaws, and teeth so sharp that it
has been seen to drive them, when angry, into a thick plank. When in a
rage it grinds them together, and, rubbing its long beard in a most
curious way, leaps about in every direction. At the slightest cause of
offence, it gives a savage grin, wrinkling the skin of its face and
jaws, and threatening the offender with the most menacing grimaces.

It seems perfectly conscious of the unusual adornment of its head,
treasuring its bushy beard with as much care and pride as does a human
exquisite. When drinking, it dips its paw, curved into the shape of a
spoon, into the water, and thus brings the liquid to its mouth. The
natives declare that it does so to avoid the risk of wetting its long
beard, of which--being generally destitute of such appendages
themselves--they fancy it must be excessively vain. As it is chiefly
nocturnal in its habits, it might be classed among the Nyctipitheci, or
night monkeys. From its fierce countenance, long, sharp teeth, and
savage temper, it has gained its second scientific name--Brachyuras
Satanus.

THE CACAJAO.

The cacajao is a curious contrast to the cuxio. It is called also the
black-headed saki. Unlike most of its brethren, it has but a short,
hairy tail, looking as if it had been docked. The head is perfectly
black, somewhat flattened at the temples, with large ears approaching in
shape to those of the human head, and devoid of hair. The fur on the
body is generally of a bright yellowish-brown. When full-grown, the
animal reaches to upwards of twenty inches in length, while the tail is
from three to five inches long. Its legs are covered with rough hair,
and its fingers are unusually long and slender, giving it an awkward
appearance when feeding. In captivity it is a docile and peculiarly
timid animal. A little creature which had been caught exhibited great
alarm at the appearance of several small monkeys of its own country; and
when a serpent was placed before its eyes, it trembled violently.

It is found on the borders of the Negro, where it is known by several
names--among others, as the mono faio, or ugly monkey.

MARMOSETS, OR MIDAS MONKEYS.

The most active, playful, and amusing of animals are the midas monkeys,
which form the second family of American Quadrumana, several species of
which exist, each in its respective district. As they are
