The monkeys, of all sizes, forms, and colors, continually chattering and grimacing, as fully represented the four-footed animals as the parrots did the bipeds.

We found there the mongoose, but little larger than a squirrel; an animal almost as intelligent as the monkey, but far more interesting and attractive.

The hideous-looking sloth, with his coarse hair, resembling Carolina moss, his repulsive physiognomy, his strong, crooked claws, his long and sharp teeth, darkly dyed with the coloring matter of the trees and shrubs which constituted his diet, was thrust in our faces in every street; and the variegated venomous serpent, with his prehensile fangs, and the huge boa constrictor, writhing in captivity, were encountered as desirable articles of merchandise at every corner.
But the MOSQUITOES at the mouth of the Amazon were perhaps the most remarkable, as well as the most bloodthirsty animals which abounded in that region.

They were remarkable not only for size, but for voracity and numbers.

This insect is a pest in every climate.
