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. ITence 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 Ghizch, whence the 
figure was described by Denon, and Ehrenberg and Do 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 kTi^os 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 
KepKos (a tail), and ttlOtikos (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. 
At hist sight they resemble the Colobi, inasmuch as they have long bodies, long hind legs, and 
long tails, but the fore limbs are short in the Guenons, and the tail, which is as long or longer than the 
body , is stout and not slender. Moreover, they have well-made and exceedingly useful cheek-pouches, 
besides the callosities behind. The face of the Guenons is long, and rounded, and the eyes are 
somewhat prominent. On examining the inside of one of these particularly African species 
the stomach is found to be single, and not to resemble that of the genera last described, and 
on looking at the lower jaw it will be found that the last crushing teeth on each side have only 
fom points, ol cusps, and not five, as in Semnopitheci. The wearing of the first premolar tooth next to 
the lower dog tooth, and behind it, resembles somewhat that noticed before, and which will be described 
in treating of the Inui, or Macaques, in the next chapter. The hands and feet are well grown, and 
the thumbs are long and useful. 
So that the distinctive peculiarity, or what is called the diagnosis of the group, or genus Cerco- 
pithecus is Monkeys with long hind and short fore limbs, and with long tails, cheek-pouches, single 
stomachs, and callosities, there being only four cusps on the last lower molar teeth. 
Many of the Guenons are often seen in menageries and zoological gardens, or as the more or 
ess unwilling companions of organ-grinders ; and their trick of crowding everything into their mouth, 
# Cercopithecus.
