Distinctive Characters of this Species.

The saki has neither pouches on the sides of his jaws, nor callosities on his posteriors. His tail is not prehensile but flaccid, and half as long again as his head and body. The apertures of the nostrils are placed on the side of the nose, and the partition is very thick. The face is brown, and covered with a fine short, whitish down. The hair on the upper parts of the body is of a deep brown, and those of the lower of a reddish white. The hair is very long on the body, and still longer on the tail, extending near two inches beyond the point; this hair on the tail is generally of a deep brown colour. There seems to be a variety in this species with respect to colour, as there are sakis to be met with whose hair is of a reddish yellow colour. This animal goes on all fours, and is about a foot and an half long, from the tip of the nose to the insertion of the tail. The females of this species have not the periodical emanation.

[THE TAMARIN.]

THIS is the name which the animal bears in Cayenne: it is called the little black monkey by some, and the great-eared monkey by others. It is much smaller than that which we have just described, and differs from it in many characters, particularly in the tail, which is cloathed only with short hair, whereas that of the saki is furnished with very long. The tamarin has also large ears and yellow feet. It is a pretty and lively animal, and very easily tamed, but so exceedingly delicate as to be unable long to resist the intemperance of our climate.

Distinctive Characters of this Species.

The tamarin has neither pouches on the sides of his jaws, nor callosities on his posteriors. His tail is flaccid, and as long again as his head and body. The partitions between the nostrils are very thick, and the apertures are on the sides, and not under the nose. The face is of a dark flesh colour. The ears are square, large, naked, and of the same colour, and the eyes are of a chesnut. The upper lip is slit, nearly like that of the hare. The body, head, and tail, are covered with a dark brown hair, and the hands and feet with a short hair of an orange colour. The body and legs are well proportioned. He walks on all fours, and measures not above seven or eight inches in length, his head included.
