Cap'uchin Monkey, or CAI, a name often given to Cebus capuchinus, and some other species of the genus Cebus, South American monkeys, which have the head covered with short hair, so disposed as to resemble the cowl of a capuchin, the face being almost naked, or only covered with a little down. Pithecia chiroptotes, a South American monkey of a genus allied to Cebus, is also sometimes called the Capuchin of the Orinoco. Cebus fatuellus is known as the Brown Capuchin. The capuchin frequents wooded country in Guiana, Venezuela, and Peru; it keeps for the most part to trees, except when pillaging maize-fields or the like; it is very shy, but easily tamed when young. Though the senses of sight and hearing are poor, its intelligence is very considerable, and can readily be educated. The mothers exhibit great affection for their young, and the captives soon become fond of their owners. As usual they are very thievish, inquisitive, and mischievous.
