OWL-FACED MONKEY

also called Hamlyn's Monkey (Cercopithecus hamlyni), arboreal guenon found in heavy forest of the Congo basin. The owl-faced monkey is greenish gray with black underparts and forelimbs and silver-gray on the lower back and base of the tail. The distinguishing feature is a white streak that runs the length of the nose and gives it an owllike appearance. See also guenon.
