lways the white
stockings and a white patch on each buttock.

SIZE.--About the same as the last two species.

This animal has bred in captivity, and has also interbred with
domestic cattle. Blyth says he saw in the Zoological Gardens of
Amsterdam a bull, cow, and calf in fine condition. "The bull more
especially has an indication of a hump, which, however, must be
specially looked for to be noticed, and he has a broad and massive
neck like the gaur, but no raised spinal ridge, nor has either of
these species a deep dewlap like the gayal" ('Cat. Mamm. Burmah').
The banteng cow is much slighter in build, and has small horns that
incline backwards, and she retains her bright chestnut colour
permanently.

_GENUS POEPHAGUS--THE YAK_.

Somewhat smaller than the common ox, with large head; nose hairy,
with a moderate sized bald muffle between nostrils; broad neck
without dewlap; cylindrical horns; no hump or dorsal ridge, and long
hair on certain parts of the body. Requires an intensely cold
climate.

_The Yak or Grunting Ox_.

NATIVE NAMES.--_Yak_, _Bubul_, _Soora-goy_, _Dong_, in Thibet;
_Bun-chowr_, Hindi; _Brong-dong_, Thibetan.

HABITAT.--The high regions of Thibet and Ladakh, the valley of the
Chang Chenmo, and the slopes of the Kara Koram mountains (_Kinloch_).

DESCRIPTION.--"In size it is somewhat less than the common or
domestic ox. The head is large, and the neck proportionally broad,
without any mane or dewlap, having a downward tendency; the horns
are far apart, placed in front of the occipital ridge, cylindrical
at the base, from which they rise obliquely outward and forward
two-thirds of their length, when they bend inward with a
semi-circular curve, the points being directed to each other from
the opposite sides; the muffle is small; the border of the nostrils
callous; the ears short and hairy. At the withers there is a slight
elevation, but no protuberance or hump, as in the Indian ox. The
dorsal ridge not prominent; body of full dimensions; rump and hinder
parts proportionally large; limbs rather small and slender; hoofs
smooth, square, and well defined, not expanded as in the musk-ox;
anterior false hoofs small, posterior large; tail short, not
reaching beyond the houghs, naked for some inches at the root, very
bushy, lax, and expanded in the middle; colour black throughout, but
varying in tint according to the character of the hairy covering;
