THIS animal ([fig. 217.]) is smaller than the tamarin, being not above six inches long, including the head; his tail is more than double that length, and annulated with black and white rings, like that of the maucauco, yet at the same time it is more bushy than that animal’s. The face of the ouistiti is naked, and of a flesh colour. He has two very singular tufts of long white hair on the fore part of the ears, which entirely conceals them when we look at the animal full in the face. Mr. Parsons has given a good description of this animal in the Philosophical Transactions; and Mr. Edwards has given a very good figure of it: he speaks of having seen several of them, and says that the largest did not weigh above six ounces, and the smallest only four and a half: he very judiciously observes, that the supposition of the small Ethiopian monkey, which Ludolph speaks of by the name of fonkes, or guereza, being the same animal as the ouistiti, has no foundation. It is very certain that neither the ouistiti, nor any other sagoin, is to be met with in Ethiopia; and it is very probable that the fonkes, or guereza, of Ludolph, is either the maucauco, or the loris, which are common in the southern parts of the Old Continent. Edwards farther says, that when the ouistiti (sanglin) is in good health he has a great deal of hair, and very bushy; that one of those which he saw, and which was healthy, fed upon several things, as biscuits, fruits, herbs, insects, and snails; that being one day unchained, he darted at a little gold fish in a glass globe, which he killed, and devoured with the greatest avidity; that afterwards some small eels were presented him, which frightened him at first, by twisting about his neck, but that he soon conquered and ate them. Mr. Edwards adds a fact which proves that these little animals might be multiplied in the southern parts of Europe. He says that they produced young in Portugal, where the climate is favourable to them. At first they have an ugly appearance, having scarcely any hair on their bodies; and they cling close to the teats of their dam. When they grow a little older they fix themselves on her back or shoulders, and when she is weary of carrying she releases herself by rubbing them off against the wall, which being done, the father, if he is by, will allow them to get upon his back.
Distinctive Characters of this Species.
The ouistiti has neither pouches on the sides of his jaws nor callosities on his posteriors. His tail is flaccid, very bushy, with alternate annulated bars of black and white, or rather brown and grey, and is as long again as the head and body. The partition of the nostrils is very thick, and the apertures are placed at the side. The head is round, and cloathed with black hair above the forehead, and above the nose is a white spot without hair. His face is almost all naked, and of a deep flesh colour. He has a tuft of long white hair on each side of the head before the ears. His ears are round, flat, thin, and naked. His eyes are of a chesnut colour. His body is covered with a soft, grey, ash-coloured hair; his throat, breast, and belly, of a light grey, with a slight tincture of yellow. He walks on all fours, and is often not above six inches long. The females are not subject to the periodical emanation.
THE Marikina ([fig. 218.]) is commonly known by the name of the little Lion Ape. We reject this compound denomination, because the marikina is not an ape but a sagoin, and no more resembles the lion than a lark resembles an ostrich, there being no affinity between them, except in the long hairs that surround the face of the marikina, and a tuft of hair at the end of his tail. His hair is long, soft, and glossy. His head is round, face brown, eyes red, ears round, and naked, and concealed under the long hairs which surround his face. These hairs are of a bright red, and those on the body and tail of a very pale yellow, approaching a white. This animal has the same manners, the same vivacity, and the same inclinations as the other sagoins. He seems to be of a more robust temperament, for we have seen one which lived five or six years in Paris, without any other particular care than keeping it during the winter in a chamber, wherein there was a fire every day.
Distinctive Characters of this Species.
The marikina has neither pouches on the sides of his cheeks, nor callosities on his posteriors. His tail is flaccid, and nearly as long again as both his head and body. The apertures of the nostrils are on each side of the nose, and the partition which divides them very thick. His ears are round and naked. The hair is long, of a yellowish red colour about the face[AA], and bright yellow hairs, nearly of an equal length, over every other part of the body; his tail is terminated with a considerable tuft of hair. He walks on all fours, and is not above eight or nine inches long.
