There are vast numbers of Monkeys living in the African forests which resemble, to a certain extent, those described in the last chapter, but which have such important differences in their construction that they are separated from them, and collected in another genus. They are said only to range in Abyssinia to the Zambesi and from the Gambia to the Congo, but probably all the equatorial parts of the Continent are frequented by them, and they extend far south. They are not found in Madagascar, and, of course, they do not frequent desert places or rocky treeless districts. Being very numerous, and extremely impudent, as a rule, and full of grimace and mischief, they soon attracted the attention of the ancients, and the beauty of the fur of some made them all the more prized. Hence they were caught, figured, and sent as presents to distant kingdoms. The ancient Egyptians knew of one, which at the present time is found in Nubia, and which is often brought to Europe, being called the Grivet. They engraved it in the catacombs of Ghizeh, whence the figure was described by Denon, and Ehrenberg and De Blainville have drawn it as represented mounted on the long neck of a Camelopard. Many coloured drawings of Egyptian origin also represent a Monkey on all-fours, with a tail curved over its back, and this is probably one of those about to be considered. They are still called _Keb_ or _Kep_ in the East of Africa, and they are doubtless the κῆβος of the Greeks. Aristotle says for certain that the Cebus, as it was translated by the Latins, is an Ape with a tail. Modern naturalists, having become acquainted with many of these species closely resembling each other in some important particulars, have arranged them all under the term Cercopithecus from κέρκος (a tail), and πίθηκος (an ape). The grimaces and odd gestures of these Monkeys have given to them the name of Guenons, and this term is now used accordingly.
