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; this, on the anterior parts, the neck, shoulders, back, and sides, is short, soft, and of a jet-black colour, but long, shaggy, pendulous, and shining on the sides of the anterior extremities, and from the medial part of the abdomen over the thighs to the hinder parts" (Horsfield, 'Cat. Mam. Ind. Mus.').
