confined in the same cage with a young hanuman, whose gravity was sorely disturbed 
by the unwearied activity and playfulness of its mercurial companion. Whilst the 
white-nose was frolicking round the cage or playing with the spectators, the 
hanuman would sit upon the perch, the very picture of melancholy and apathy, 
with his long tail hanging down to the bottom; but his attention was roused and 
his security endangered every moment by the tricks of the restless little creature, 
which in its sports and gambols continually caught the hanuman’s tail, either to 
swing itself out of the reach of the spectators, or, like a boy at his gymnastic 
exercises, to assist it in climbing up to the perch. All this, however, was done with 
great good-nature on both sides, and it was highly diverting to see the playful 
innocence of the one, and the gravity with which the other regarded it, like a fond 
parent enjoying the innocent follies of a favourite child.” 
The Ludio Monkey (Cercopithecus Indio). 
The last of the guenons that we shall notice is the ludio monkey, which is 
another of the white-nosed group. Its fur is black, profusely grizzled with grey; 
the chin, chest, and the inner sides of the upper arms being white; while the temples, 
nape of the neck, shoulders, and the greater portions of the limbs, as well as the 
end of the tail, are pure black. The white spot on the nose has an oblong shape, 
and is higher than broad. 
The species is said to range into Central Africa. The red-eared monkey (0. 
erythrotis), which is likewise West African, differs from the other members of the 
group in having red hairs on the nose and ears. 
The Mangabeys, or White-Eyelid Monkeys. 
Genus Cercocebus. 
The mangabeys, or, as they are often called, white-eyelid monkeys, comprise a 
small group of four West African species, which, while agreeing in all external char¬ 
acters with the guenons, are distinguished by the presence of a projecting heel at the 
hinder end of the last molar tooth on each side of the lower jaw, so that the crown 
of this tooth carries five, in place of four tubercles. In this respect the mangabeys 
agree with the great group of macaques, which follow next in the series; and on 
this ground these monkeys have been separated from the guenons to form a distinct 
Q'enus under the name of Cercocebus. There has been much discussion as to the 
O 
advisability of thus separating the mangabeys, but it has at least the advantage of 
somewhat restricting the unwieldy group of the guenons. 
The name Mangabey, it may be observed, is taken from the district Mangabe, 
or Manongabe, in Madagascar, and was applied by the French naturalist Buffon to 
these monkeys, from the mistaken idea that they came from that island, which in 
his time appears to have been a kind of refuge for the destitute, in regard to animals 
whose habitat was unknown. In spite, however, of this totally erroneous origin the 
name is a convenient one, and has been subsequently almost universally adopted 
for this group of monkeys.
