Head oblong, long, rounded, and wrinkled; face and chin naked; eyes approximated, set deep below the superciliary ridges; brow small; neck short. Ears pointed at their hind upper angle, and their margins haired; nose not prominent; nostrils two slit-like orifices converging at right angles to the partition; lips slender, extensile; upper {5}lip broad; callosities less extensive than in the Baboons; tail invisible externally; toes longer than the fingers, and both much haired. Hair on the crown short and reflexed; hairs on the cheeks forming a whisker, directed backward; hair of the fore-arms directed towards the elbow. Crown, and sides of head, cheeks, neck, shoulders, upper back, and front of fore-limbs golden-yellow, mixed with a few black hairs, the individual hairs being dark grey at the base, ringed for the rest of their length with yellow and grey; the rest of the upper part of the body greyish-yellow or yellowish-brown; under side of lower jaw, lower side of body, and inner face of limbs greyish-yellow, or yellowish-white; a dark spot of black hairs tipped with yellow at the inner angle of each eye, and stretching down on the cheeks; naked parts of face, ears, and callosities pale flesh-colour, as also is the thinly-haired skin of the inner sides of the limbs; tail represented by a small tubercle of naked skin. Length of the body, 2½ feet. FEMALE.--Exactly resembles the male in coloration, but is slightly smaller in size, and more amiable in disposition; the canines scarcely larger than the incisors. DISTRIBUTION.--This species, named by the French "Magot," inhabits Morocco, and Algeria in Northern Africa. It is found also on the Rock of Gibraltar, and some distance inland in Spain; but whether it has been transported from Africa, or has lived there since its ancestors were left isolated when the Straits of Gibraltar subsided and separated Europe from Africa, is a question impossible to decide now. It is certain that the Moors bring now, and probably for ages have been in the habit of bringing, captive specimens of this Monkey, to trade away on the European side; it is, therefore, {6}not impossible that the "Apes of the Rock" may have thus been introduced. This is the only African (or European) species of the genus.
