Characters.—Size very small, the height at the shoulder being about
3 feet 3 inches ; limbs rather short, body plump, neck thick, and withers
rather higher than the hind-quarters. Horns of male of moderate length,
arising far below the plane of the occiput, ringed and triangular at the base,
nearly straight, and directed upwards and outwards nearly in the plane of
the forehead, with the tips sharply pointed. Ears small, well haired at
the bases, but becoming almost naked at the tips,'and with a tuft of long
white hair on the inner-jside. Tail reaching about to the hocksf In
young animals the skin of the body covered thickly with somewhat woolly
hair, which becomes gradually more and more sparse with advancing age,
until in old individualfjlt is almost completely bare ; hair of middle line of
back reversed from the occiput to the haunches, as in the Indian buffalo
and tamarau. In young animals the general colour of the hair yellowish-
brown ; in adults the colour varying from dark brown to blackish, often
with white spots in front of the lateral hoofs, on the throat, the hinder part
of the neck, the back, in front of the eyes, and on the sides of the lower
jaw, while the inner sides of the cannon-bones may also be white, as are
the inner surfaces of the ears ; under-parts generally light brown. Old bulls
from which the hair has almost disappeared have the skin as black as in
the Indian buffalo. In the lower jaw there are frequently only two lower
premolar teeth, although there may be three of these teeth, as in almost
all other Bovidas. Although thelfesipital surface has not the prominent

crest found in adults "of the larger buffaloes, when Compared with that of a
young Indian buffalo the skull -is almost identical, the resemblance being
carried even to the continuation of the vomer as far back as the hinder
margin of the palate. As in the tamarau and other buffaloes, the number
of pairs of ribs is usually thirteen, although one instance of the presence of
fourteen pairs has been recorded by Dr. Heller.
The difference between an anoa skull and that o f an adult Indian
buffalo is probably in part due to the inferiority in the size of the present
species, since it is an established fact that the smaller representatives of a
group tend to retain the generalised features of the ancestral type which
