animal, evincing in their own way the most tender regard for it, 
and then suddenly becoming irritated, pursuing it with hoarse 
cries, and biting it as if it were an enemy ; immediately peace is 
made, and the caresses recommence and continue, until a new 
caprice brings about the same results.” 
The female of the Guenons shows much affection for its young. 
During the first weeks of its existence she keeps it pressed against 
her breasts, maintaining it there with her anterior hands, after the 
manner of other Monkeys. At a later period, however, the young 
one clings by itself to its mother, who goes about, climbing and 
jumping, with as much agility as if the load she bore had neither 
weight nor substance. The male not only does not share with the 
female the care of rearing their progeny, but he frequently mal- 
treats both. So that at this period it is sometimes necessary in 
menageries to lodge them apart, to prevent violence. 
The pelage of these Monkeys is nearly always agreeably varied ; 
the colours are vivid and the shades well assorted. It is owing to 
this beautiful combination of tints that certain of their skins are 
valuable. 
Among the species which are graceful in shape and naturally 
pacific, we will mention the Talapoin, the Shaker, the White-Hose 
(Fig. 259), the White-lipped Cercopithecus, the Mona. In the 
second section, the Yervet, the Grivet (Fig. 260), the Callitriche, 
the Patas, and the Hisnas. 
The Talapoin and Mona are the gentlest and the most intelli- 
gent; the most intractable are the Grivet, the Malbruck, and the 
Patas. The Grivet and the Hisnas were known to the ancient 
Egyptians : this is proved by the figures engraved on their tombs 
and obelisks. 
Tribe of Semnopitheci. — The Semnopitheci (Grave Monkeys 
— trefivos, grave, t tWtjkoq, Monkey) are characterised by a very short 
muzzle, a slender, lanky body, a muscular tail — surpassing in 
length that of all the other Monkeys of the Old World — thumbs 
of the anterior extremity very short or entirely absent, callo- 
sities marked, and by the almost complete absence of cheek- 
pouches. Their coat is usually long and abundant. 
They differ but little from the Guenons in their collective 
habits, though they show less petulance in their movements and
