_Distinctive Characters of this Species._ The coaita has neither pouches on the sides of his jaws, nor callosities on the posteriors: he has a very long prehensile tail. The partition of the nostrils is very thick, and the apertures are placed on the side, and not under the nose. He has only four fingers on his hands or fore-feet: his hair and skin are black: his face is naked and tawny: his ears are also naked, and of the same form as the human race. He is about a foot and a half long, and his tail is longer than the head and body together; he walks on all fours. The exquima is nearly of the same size as the coaita, and, like that animal, has a prehensile tail; his hair, however, is not black, but variegated. There are some which are black and brown on the back and white on the belly, with a very remarkable beard. These differences, however, are not sufficient to constitute two different species, especially as there are coaitas not entirely black, but which have a whitish hair on the throat and belly. _Engraved for Barr's Buffon._ [Illustration: FIG. 213._Coati._ FIG. 214. _Brown Capuchin._] [Illustration: FIG. 216. _Saki._] THE SAJOU.[X] [Footnote X: This word is abridged from _cayouvassou_ or _sajouassou_; the names by which these animals are called at Maragnon.] We are acquainted with two varieties in this species, the Brown Sajou, (_fig. 214._) commonly called the _capuchin monkey_; and the Grey Sajou, which differs from the other only in the colour of its hair. They are of the same size, the same shape, and the same disposition: both are lively, active, and very amusing, by their tricks and nimbleness. We have had them alive; and of all the sapajous they appeared to be those with which the temperature of our climate seemed least to disagree. They live here for many years without much trouble, provided they are kept in a warm room during winter. We can even give examples of their producing in this country. Two were brought forth at Madame de Pompadour's, at Versailles, one at M. de Reamur's, at Paris, and another at Madame de Poursel's, in Gatinois; but these were only single productions, whereas in their own climate they often bring forth two. These sajous are very fantastical in their tastes and affections: they are extremely fond of some persons, and have as great an aversion for others. We observed a singularity in these animals, which causes the females to be often taken for the males. The clitoris is prominent outwardly, and is as much seen as the sexual organ of the male. _Distinctive Characters of this Species._
