\A 
THE MANDRILL.—Pépio Maimon. 
—T= 
Only the male Mandrill possesses these strange adornments in their full beauty of 
size and colour, the females being only gifted with the blue tint upon the muzzle, and 
even that is of a much less brilliant hue than in the male. The cheek-bones are but 
little elevated above the face, and are without the deep furrows that give so strange an 
appearance to the male sex. : 
Even in the male animal, these ornaments do not fully develop themselves until the 
creature has attained maturity. Not until the task of dentition is fully accomplished 
does the Mandrill shine out in all the glory of his huge azure nose, his crimson mouth, 
and carmine termination. 
Of all the baboons, the Mandrill appears to be the most hopelessly savage, though 
examples are not wanting of individuals which have been subjected to kind treatment, 
and have proved tractable and gentle—that is, for baboons. 
The adult Mandrill is liable to terrible gusts of passion, during which it seems to be 
bereft of reason and possessed with an insane fury. That which in other monkeys is 
a hasty petulance, easily excited and soon passing away, becomes in this animal a 
paroxysm of wild and blind rage, to which the anger of an ordinary monkey is but 
a zephyr to a tornado. 
When thus infuriated—and but small cause is needed for its excitation—the animal 
seems to be beside itself with fury, heedless of everything but the object of its anger.
