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. This monkey, Macacus inuus, is light yellowish-brown above and yellowish-white below, with the naked part of the face flesh-coloured. It is entirely terrestrial in habits, at least on Gibraltar, and goes about in droves.
