Monkey, S. chrysomela, all of Borneo ; the Black-crested Monkey, S. melalophos^ and the 
Yellow-handed Monkey, S. fiavimanus, of Sumatra; the Siam Monkey, S. Siamensis of Muller, 
or Black-handed Monkey, S. nigrhnanus of GeofFroy, found in Siam and Southern Asia ; and 
the Mitered Monkey of Java, S. comahcs, called Croo by the natives. 
Among these numerous species there are certain distinctions of structure which have led some 
naturalists to range them under different divisions. They are, however, so nearly allied as to ren- 
der them a natural and homogeneous group in the great and diversified family of monl^eys. 
Genus COLOBE, Colohus. — The monkeys of this genus are almost destitute of thumbs on the 
anterior limbs, and hence their name, derived from the Greek, Icolobos, mutilated. They resemble 
the preceding in their intelligence and in their habits, living like them in forests, and feeding upon 
vegetable substances. The known species all belong to Africa. 
The GuEREZA Monkey, Colohus Guereza, is found in Abyssinia, and is distinguished for the 
beauty of its skin, the greater part of the body being black ; its forehead, and a circle around the 
face, with the sides, neck, and throat, are pure white. A sort of mantle of long white hair starts 
from the sides, near the back, and descends in flowing masses along the after part of the body. 
These animals live in small families, dwelling in the tops of large trees in the neighborhood of 
flowing waters. They are exceedingly nimble and lively, without being boisterous. They feed on 
fruits, grain, and small insects. The inhabitants of some parts hunt them, and it is a mark of dis- 
tinction among the soldiers to possess a shield covered with the skin of this monkey, displaying 
the full flying mantle we have described. 
The Golobus polycomos of Sierra Leone goes by various names, as King of the Monkeys, Bear 
Monkey, Full-bottomed Monkey, &c. The color is generally black, tinged with yellow on the 
fore parts. The hair of the head is long, and falls in such a manner as to appear like a camail — a 
small cloak, covering the upper part of the body ; hence the French call this animal C. a camail. 
The other species of this genus are the C. satanas, of the island of Fernando Po ; the Furred 
Monkey, G. vellerosus ; the Bay Monkey, G. ferrugineus, of Sierra Leone; the G. fuliginosus, 
of Senegambia ; and the True Colore, G. verus, of Western Africa. 
Genus CERCOPITHECUS. — This term is derived from the Greek Jcerkos, the tail, and pithekos, 
an ape. The genus embraces the Guenons of French naturalists. Nearly thirty species are known, 
all belonging to Africa. They are distinguished from the genus Semnopithecus by a less slender 
form, a longer face, and larger cheek-pouches, in which they often preserve their food for a time. 
They are between one and two feet in length, and are generally marked by a certain elegance of 
form. They are covered with fine hair, and this is often distinguished for the brilliancy of its 
color. The tail is generally the length of the body, and carried over the back. They do not
