This monkey, Macacus inuus, is light yellowish-brown above and yellowish-white below, with the naked part of the face flesh-coloured.
The primary attitude of man to the numina seems clearly to be one of fear, which survives prominently in the "impish" character of certain of the spirits of the countryside, such as Faunus and Inuus, and is always seen in the underlying conception of religio, a sense of awe in the presence of a superhuman power.
As such he is akin to or identical with Inuus ("fructifier") and Lupercus (see Lupercalia).
The Romans identified him with Inuus and Faunus.
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.
The magot or Barbary ape (Inuus ecaudatus), the sole species of monkey still found wild in Europe, is also a native of Spain, but only survives on the rock of Gibraltar (qv.).
