DIANA MONKEY, a West African representative of the guenon monkeys taking its name, Cercopithecus diana, from the presence of a white crescent on the forehead; another characteristic feature being the pointed white beard. The general colour of the fur is greyish, with a deep tinge of chestnut from the middle of the back to the root of the tail. Together with C. neglectus of East and Central Africa, C. ignitus of Liberia, and C. roloway of the gold Coast, the diana represents the special subgenus of guenons known as Pogonocebus. Although the diana monkey is commonly seen in menageries, little is known of its habits in the wild state.
