animal, evincing in tteir 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 j^oung 

 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 AVh.ite-Nose 

 (Fig. 259), the White-lipped Cercopithecus, the Mona. In the 

 second section, the Vervet, the Grivet (Fig. 260), the Callitriche, 

 the Patas, and the Nisnas. 



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 Nisnas 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 

 — aifjLvos, grave, irWriKot, 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
