Fur long, fine, and silky, longest on the shoulders, neck, and upper surface of feet; hair on the top of the head not radiated; ears hairy; callosities surrounded by hair; a naked red spot at the outer angle of the eyes; tail about one-fourth of the body in length.
Male.—Dark rich olive-yellow; face pale flesh-colour; sides of the face, neck, and front part of the body olive-grey; hinder parts of the body brick-red; the slaty colour of the fore-limbs, and of the anterior aspect of the legs becoming black on the hands and feet; ears flesh-colour; callosities crimson; throat, chest, and inside of the fore-limbs greyish, washed with rufous above the wrists; belly and inside of the hind limbs greyish, washed with orange-red.
Female.—Fawn-colour, washed with red, especially on the lower back. Face brighter coloured than in the male. Tail one-fourth the length of the body.
Skull more massive, shorter, and markedly broader and with a more vertical muzzle than M. rhesus.
Distribution.—Province of Szechuen, W. China: Dupleix Mountains, 13,000 feet. (Bonvalot.)
Habits.—Little is known of the habits of this Chinese representative of the Bengal Macaque. In the winter it is said to have a splendid coat of rich brown hair, very long and thick. It is very fierce and powerful.
