CHARACTERS.--Head round; hairs of crown short and reversed, sometimes
elongated into two retrorsal tufts. Fur short, close, and in general colour
maroon, turning to black, darker on the under surface; face, chin, sides of
forehead and a streak above the eyebrows, yellowish-white.
DISTRIBUTION.--Lower Amazon region.
HABITS.--Little is known of this Monkey beyond what Mr. Bates has told us,
viz., that it is a great depredator of the fruit trees. "It is a most
impudent thief; it destroys more than it eats by its random, hasty way of
plucking and breaking the fruits, and when about to return to the forest,
carries away all it can in its hands or under its arms."
