They go in large bands, living chiefly in the trees, but often descending on the ground and robbing gardens and orchards.
Anoa depressicornis, the Sapi-utan, or wild cow of the Malays, is an animal which has been the cause of much controversy, as to whether it should be classed as ox, buffalo, or antelope.

It is smaller than any other wild cattle, and in many respects seems to approach some of the ox-like antelopes of Africa.

It is found only in the mountains, and is said never to inhabit places where there are deer.

It is somewhat smaller than a small Highland cow, and has long straight horns, which are ringed at the base and slope backwards over the neck.
The wild pig seems to be of a species peculiar to the island; but a much more curious animal of this family is the Babirusa or Pig-deer; so named by the Malays from its long and slender legs, and curved tusks resembling horns.

This extraordinary creature resembles a pig in general appearance, but it does not dig with its snout, as it feeds on fallen fruits.
