VIII. THE BROWN-HEADED SPIDER-MONKEY. ATELES FUSCICEPS.
Ateles fusciceps, Fraser MSS.; Gray, P. Z. S., 1865, p. 733; Sclater, P. Z. S., 1872, p. 663, pl. lv.; Gray, Cat. Monkeys Brit. Mus., p. 42 (1870); Schl., Mus. Pays Bas, vii., p. 173 (1876).
Characters.—Fur thick. Hairs long, shining, crisp, deep black above, the hairs of the back with brownish tips; the under side of the body and inside of the limbs black; crown of head deep coffee-brown. Length of body about 20 inches; of the tail, 26 inches, according to the dimensions taken from the skin of a young animal by Dr. Sclater. Thumbs entirely wanting.
Distribution.—In 1860, when Mr. L. Fraser returned from Ecuador, he spoke of a large Monkey he had seen, but had not obtained, in the valleys of Western Ecuador. It remained unknown until it was shot, and brought to England by Mr. Buckley some ten years later. It was the only Monkey, he says, except a Mycetes, which he saw in Trans-Andean Ecuador.
Habits.—These, doubtless, do not differ from those of other Spider-Monkeys.
IX. THE HOODED SPIDER-MONKEY. ATELES CUCULLATUS.
Ateles cucullatus, Gray, P. Z. S., 1865, p. 733; id. Cat. Monkeys Brit. Mus., p. 42 (1870); Murie, P. Z. S., 1865, p. 739; Schl., Mus. Pays Bas, vii., p. 169 (1876).
Characters.—Hairs of body long, but thin on the head, body, limbs and tail; hair of crown very long and projecting over the face and the sides of head, forming what has been called a "hood." Face nude, flesh-coloured; cheeks and lower jaw nearly nude also, but the skin of a blackish hue. Hair on back black, intermingled with numerous others which are yellowish-grey in colour; crown and back of head, hands, and feet black—the hairs black throughout. Nude part of tail flesh-coloured. The hands have a rudiment of a thumb in the shape of a small tubercle. Length of body, 14½ inches; of tail, 27½ inches.
Distribution.—The Hooded Spider-Monkey is very rare, and very different from any other member of its group in regard to the hair of its head. Its native country is still a matter of uncertainty. Dr. Sclater, however, remarks in the "Proceedings of the Zoological Society" for 1881: "I have some reason to suppose it may be from the northern coast of Colombia, as I am told that a black Spider-Monkey, with long hair over its head, is occasionally brought for sale into Cartagena."
