trembled with fear, while its teeth chattered, and it uttered a
tremulous, frightened tone, at the approach of a stranger.

SAI CAPICINUS.

The most attractive little creatures in the American forests are the
capucins, the best-known of which is the Sai capucinus. Their tails,
though covered with hair, are prehensile. They are active and lively in
the extreme, leaping about from bough to bough, and eagerly watching all
that goes forward in the world below. There are several species of
similar habits, their quaint ways and general intelligence making them
all great favourites when tamed. They live chiefly on vegetable food,
but they devour insects and eggs, and do not object to a bird when they
can manage to catch one.

HORNED CAPUCIN.

The horned capucin, or sapajou (Cebus fatuellus), is remarkable for two
points of hair which stand out from the forehead, and give it the
appearance of having horns. The colour is sometimes of a deep brown,
and at others of a purple-black, while occasionally it has a chestnut
tint.

THE COMMON CAPUCIN.

The hair of the common capucin is of a golden olive, with white fur
bordering the face.

These curious little creatures are noted for forming a friendship with
other animals when in captivity. Baron Humboldt mentions one which used
to mount on the back of a pig every morning, and continued sitting there
during the whole of the day; and even when the pig went out feeding on
the campos, it still kept its seat, riding back again in the evening to
its home. Others have been known to choose cats for their steeds, and
perseveringly to keep their hold in spite of their active movements--
seeming to enjoy them as much as the llanero does those of a colt he is
engaged in breaking-in.

PARAUACU.

On the dry lands to the north of the Upper Amazon, a little timid
inoffensive monkey is found with a long bear-like coat of speckled grey
hair. The long fur hangs over its head, half concealing a pleasing
diminutive face; the tail--to the very tip--which is of some length, is
also completely covered.

PITHECIA HIRSUTA--PITHECIA ALBICANS.

There are two more species--the Pithecia hirsute and the Pithecia
albicans. They are especially capable of attachment to those who treat
them kindly. Being somewhat dull and cheerless, they seldom indulge in
the usual sportive movements of their race.

Mr Bates relates that a friend of his possessed one of these little
creatures. His friend, a
