Douroucouli (nyctipithecus trivirgatus), a small monkey found in Guiana and Brazil. In this genus the middle incisors are broad, and the canines moderate; eyes large; external ears not prominent beyond the fur; hind feet longest; tail longer than the body, not prehensile. As its generic name implies, it is nocturnal, sleeping by day, but very active and fierce at night in search of insects and small birds. It is about 9 in. long, with a tail of 14 in.; the fur is soft, grayish white, with a brown line on the back, three dark stripes on the head, and yellowish brown below. It looks more like a cat than a monkey, and the mouth is surrounded by bristly white hairs. When seated it assumes the position of a dog, and when sleeping the head is bent forward between the feet; it is difficult to tame, and its voice is loud and disagreeable. Humboldt called it aotes, earless, though the ears are not particularly small. It lives in pairs, and resembles in appearance and habits the lemurs of the old world. F. Cuvier gave it the name of noc-thora, from its nocturnal habits.
