s, and would climb up to his head a dozen times in
the course of an hour, making a great show every time of searching there
for certain animalcula.

Isidore Geoffrey St. Hilaire relates of a species of this genus that it
distinguished between different objects depicted on an engraving. M.
Audouin showed it the portraits of a cat and a wasp; at these it became
much terrified; whereas at the sight of a figure of a grasshopper or
beetle it precipitated itself on the picture, as if to seize the objects
there represented.

Although monkeys are now rare in a wild state near Para, a great number
may be seen semi-domesticated in the city. The Brazilians are fond of
pet animals. Monkeys, however, have not been known to breed in captivity
in this country. I counted in a short time thirteen different species
while walking about the Para streets, either at the doors or windows of
houses, or in the native canoes. Two of them I did not meet with
afterwards in any other part of the country. One of these was the
well-known _Hapale jacchus_, a little creature resembling a kitten,
banded with black and gray all over the body and tail, and having a
fringe of long white hairs surrounding the ears. It was seated on the
shoulder of a young mulatto girl, as she was walking along the street,
and I was told had been captured in the island of Marajo. The other was
a species of Cebus, with a remarkably large head. It had ruddy brown
fur, paler on the face, but presenting a blackish tuft on the top of the
forehead....

The only monkeys I observed at Cameta were the Couxio (_Pithecia
satanas_), a large species, clothed with long brownish black hair, and
the tiny _Midas argentatus_. The Couxio has a thick bushy tail; the hair
of the head sits on it like a cap, and looks as if it had been carefully
combed. It inhabits only the most retired parts of the forest, on the
terra firma, and I observed nothing of its habits. The little _Midas
argentatus_ is one of the rarest of the American monkeys. I have not
heard of its being found anywhere except near Cameta. I once saw three
individuals together running along a branch in a cacao grove near
Cameta; they looked like white kittens: in their motions they resembled
precisely the _Midas ursulus_ already described.

I saw afterwards a pet animal of this species, and heard that there were
many so kept, and that they were esteemed as choice treasures. The one I
saw was full grown, but it measured only seven
