(1878) ; Lydekker, Cat. Foss. Mamm. Brit. Mus. pt. ii. p. 36 (1885).
CharacterrE-Imperfectly known, but apparently distinguished from the
last species by the more slender form of the skull of the male and the
more upright direction of the horn-cores, of which the bases alone are
preserved.
Distribution.— India during the early Pliocene period, the remains
occurring in the freshwater deposits of the Siwalik Hills. An allied
species, Bos fraseri, said to be still more nearly allied to the banting, occurs
in the Plistocene deposits of the Narbada Valley, India.

C/W-tfc/frfg-Typically the horns cylindrical, widely separated from one
another, and situated on a ridge below the extreme vertex of the skull, so
that in a front view the summit of the crest of the true occiput is visible ;
the forehead of the skull relatively short, wide, and more or less': convex,
the interval between the bases of the horn-cores and the sockets of the eyes
