The animal which Marcgrave calls _exquima_ is very similar to the _coaita_, and, perhaps, is only a variety of that species. This author seems to have been deceived when he said that the exquima was a native of Guinea and Congo. The figure he has given of it, is alone sufficient to demonstrate his error; for the animal is there represented with a tail curled at the extremity, a character which belongs solely to the sapajous; consequently, the exquima of Marcgrave is not, as he tells us, a monkey of Guinea, but a sapajou with a prehensile tail, which, without doubt, had been transported there from Brasil. The word _exquima_, or _quima_, expunging the article _ex_, ought to be pronounced _quoima_, and then it is not very distant from _quoaita_, which is written coaita by many authors. Every circumstance, therefore, concurs to prove, that this _exquima_ of Marcgrave was a sapajou of Brasil, and only a variety of the coaita, which it resembles in nature, size, colour, and the prehensile tail. The only material difference consists in the exquima having a whitish hair on the belly, and a white beard under the chin, about two inches long. Our coaitas have neither this white hair nor the beard: but what makes me still presume that this difference is not sufficient to constitute two distinct species is the testimonies of travellers, who tell us, that there are both black and white coaitas, and that some of them have beards, and others are without. "There are (says Dampier) in the isthmus of America, great numbers of monkeys, some of which are white, but the most of them black; some have beards, others none: they are of a middling size, and in dry weather when the fruits are in season they are very fat; their flesh is then extremely good, and we ate great numbers of them, which example was after a time followed by the Indians, who were shy of eating them at first. In the rainy seasons these animals have a quantity of worms in their bowels, and I have seen some of them several feet long.--These monkeys are very droll, and played a thousand grotesque tricks as we traversed the woods; leaping from branch to branch with their young upon their backs, making faces, chattering, and even seeking opportunities to make water upon our heads. When they are unable to leap from one tree to another, on account of the distance, their dexterity is very surprising; they form a kind of chain, hanging down by each other's tails; one of them holding the branch above, the rest swing to and fro like a pendulum, until the undermost is enabled to catch hold of the branches of the other tree, when the first lets go his hold and thus comes undermost in his turn; and then, by degrees, they all get upon the branches of the tree without ever coming to the ground." All these particulars perfectly agree with our coaitas. M. Daubenton, in his dissection of these animals, found a great quantity of worms in their entrails, some of which were from twelve to thirteen inches long.
