The Mono AVM discovered by Prince Maximilian of Neuwied, during his travels in Brazil. It is the largest species of the Qundrumanes which inhabit the part of the country through which that scientific traveller passed. and though aufficientlyconnnon in particular districts, appears to have upon the whole but a very limited geographical range. Its hide is said to be mono impervious to moisture than any other description of fur known in that part of the world, and for this reason the Brazilian sportsmen have cases of the skin of the Mono made to protect the locks of their guns from the rain.
8. A. subrentudactylas (Geoffrey), the Chameek, the last species of the genus distinctly known at present, resembles the Mono in having a small rudimentary thumb on the anterior extremities, hut it is without a nail, and in other respects the two animals are sufficiently distinguished by their difference of colour and habitat. The Chameck indeed approaches more needy in external form and appearance to the Qunta than to any other of its congeners, being fur-Mailed with a similar coat of long dense hair, of an intense and uniform black colour ; but It may be readily distinguished from that species by the presence of the rudimentary thumb on the anterior members, as well as by its size, which considerably exceeds that of the Quida. It line a protuberant muzzle, and its lips, like those of the Quata, are capable of prolongation ; the forehead is high ; the face, cheeks, care, and chin, are naked and of a brown colour, with a few long black hairs thinly scattered over them ; the hair of the head is long, matted, and directed forwards over the forehead, that of the body and members very long and thick; the fingers, both upon the anterior and posterior extremities, are long, slender, and nearly naked ; the tail is considerably longer than the body, very thick and covered at the base with close shaggy hair, but attenuated towards the point, where it is more sparingly furnished with shorter hair, and entirely naked underneath.
This species inhabits Guyana and some of the neighbouring provinces of BraziL Von Sack, in his Voyage to Surinam, gives the following account of its manners under the name of Quata, with which species its general appearance probably causes it to be frequently confounded. "The Quata," says this author, "is of a very docile disposition, and capable of being quite domesticated. I have seen a pair of them at a gentleman's house at Paramaribo which were left quite at liberty. When the female negroes were employed at their needlework, they used to come and sit amongst them, and play with a piece of paper, and afterwards go out to gambol upon the trees, but never went over to the neighbouring gardens ; and they knew well the usual hour of dinner at their master's, when they would come to the gallery, look in at the windows, though without attempting to enter into the room, being aware that this was a liberty not allowed them ; they therefore patiently waited for their dinner on the outside."
