HULOCK GIBBON.

The great length of arm in comparison with the body and head should here be noted.

MONKEYS.

The Dog-shaped Monkeys.

After the gibbons come a vast number of monkeys of every conceivable size, shape, and variety, which naturalists have arranged in consecutive order with fair success. Until we reach the Baboons, and go on to the South American Monkeys and the Lemurs, it is not easy to give any idea of what these monkeys do or look like merely by referring to their scientific groups. The usual order of natural histories will here be followed, and the descriptions will, so far as possible, present the habits and appearance of the monkeys specially noticed.
