leoninus, a species first described by Humboldt, which was still
more playful and intelligent than the one just described. This
rare and beautiful little monkey is only seven inches in length,
exclusive of the tail. It is named leoninus on account of the
long brown mane which depends from the neck, and which gives it
very much the appearance of a diminutive lion. In the house where
it was kept, it was familiar with everyone; its greatest pleasure
seeming to be to climb about the bodies of different persons who
entered. The first time I went in, it ran across the room
straightway to the chair on which I had sat down, and climbed up
to my shoulder; having arrived there, it turned round and looked
into my face, showing its little teeth and chattering, as though
it would say, "Well, and how do you do?" It showed more affection
towards its master than towards strangers, 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 Geoffroy 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, whilst 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
