The Semnopithicus nemæus is described as very extremely pretty, though at the same time peculiarly coloured: the orange-coloured tinted face is surrounded by long whiskers of glossy whiteness, with a line of chestnut-red over the eyebrows; the fur on the whole back is of a delicate grey, with but a square patch on the loins; the whole long tail and the forearms are purely white; a gorget of chestnut caps the chest; the hinder thighs are black with be the legs chestnut-red. I will mention only two other monkeys on account for their beauty; which and I have chosen selected them as they present slight sexual differences in colour which rendersing it more in some degree probable that both sexes owe their elegant appearance of both sexes is wholly due to sexual selection.

In the moustache monkey (Ceropithicus cephus) the general colour of the fur is mottled-greenish, with the throat white and with the end of the tail in the male chestnut; but the face is the most ornamented part, the skin being chiefly bluish-grey, shading into a blackish tint beneath the eyes, and with the upper lip of a delicate blue, clothed on the lower edge a thin black
