White-tailed Group, Subgenus Dorcelaphus or Odocoileus.- Antlers large and complex, with a sub-basal snag, and the lower prong more or less developed at the expense of the upper one; metatarsal gland usually present; tail long or moderate, and hairy below; face very long and narrow; the face-gland small, and the gland-pit in the skull of moderate extent; no upper canines; size generally large.
The members of the subgenus Guereza present a transition from a wholly black animal (C. satanas) to one (C. caudatus) in which the sides of the face are white, and the whole flanks, as well as the tail, clothed with a long fringe of pure white hairs.
Other east African monkeys with a similar type of colouring, which, together with the wholly black west African C. satanas, collectively constitute the subgenus Guereza, may be included under the same title; and the name may be further extended to embrace all the African thumbless monkeys of the genus Colobus.
The Chilian and Peruvian Andes and Patagonia are the homes of two peculiar deer locally known as guemals (huemals), and constituting the subgenus Xenelaphus, or Hippocamelus.
BARBARY APE, a tailless monkey inhabiting Algeria, Morocco, and the rock of Gibraltar (where it may have been introduced), and referable to the otherwise Asiatic group of macaques, in which it alone represents the subgenus Inuus.
Displaying great variability in the length of the tail, which is reduced to a mere tubercle in the Barbary ape, alone representing the subgenus Inuus, macaques are heavily-built monkeys, with longer muzzles than their compatriots the langurs (see PRIMATES), and large naked callosities on the buttocks.
Together with the drill (q.v.), the mandrill, Papio maimon, constitutes the subgenus Maimon, which is exclusively West African in distribution, and characterized, among other peculiarities, by the extreme shortness of the tail, and the great development of the longitudinal bony swellings, covered during life with naked skin, on the sides of the muzzle.
Monteiroi of Angola, this represents the subgenus Otolemur.
The named Arabian baboon, P. hamadryas of North Africa and Arabia, dedicated by the ancient Egyptians to the god Thoth, and the South Arabian P. arabicus, typify Hamadryas; while the drill and mandrill of the west coast, P. leucophaeus and P. maimon, constitute the subgenus Maimon.
Fallow-deer, Subgenus Dama.
