cranium, including orbit, nasal bones, and palate, and four posterior 
molars on either side. The forehead is mutilated and the horn-cores 
are broken off.—B.M. No. 39,758. 
Bos Paleindicus (Fale. and Caut.), from the Nerbudda. 
Figs. 3 and 3 a.—Fragment of cranium, including orbits, horn-cores, 
frontal and occipital, on both sides.—B.M. No. 39,716. 
Vig. 4.—Fragment of cranium, showing occiput, foramen magnum, 
condyles, and horn-cores.—B.M. No. 39,717. 
Figs. 5 and 5a.—Fine specimen of cranium, showing occiput, condyles, 
and foramen magnum, portion of right horn and left horn-core, both 
orbits, palate, and four posterior molars. The upper surface of the 
frontal is arched. The horn-cores spread out more horizontally, and 
with a less inclination upwards than in the existing wild buffalo, and 
are slightly concave anteriorly and convex behind. In these respects 
it differs from the existing wild buffalo, and so far as the horizontal 
offset is concerned, it approximates to the Gayal, from which, however, 
it differs in the flattened form of the horns and in every other respect. 
These characters are so constant that there can be little doubt that the 
species is distinct from the existing wild buffalo.—B.M. No. 39,759. 
Fig. 6 —Fragment showing anterior portion of upper jaw, with in- 
termaxillary bones.—B.M. No. 59,715. 
Figs. 7 and 7 a.—Fragment of horn, broken off at tip, and of a com- 
pressed form. Fig. 7 a shows the flattened form of the horn, as seen 
at section. This, as well as the fragment represented in fig. 6, have 
been found to belong to a skull in the British Museum (No. 39,715), to 
which they are now attached. (See postea, p. 134.) 
Length, 33:5 in. Greatest diameter, 6°5 in. Least ditto, 3°25 in.

Hemibos triquitriceras. (Fale. and Caut.), from the Sewalik hills. 
Figs. 1 and 1 @.—Cranium, including both orbits and horn-cores, 
occiput, nasals, palate, and entire molar series on both sides.—B.M. 
No. 39,584. 
Length of fragment, 18:2 in. Great diameter of core, 4° in. Breadth of cranium 
at post. angles of orbits, 87 in. Great diameter of orbit, 2°7 in. Length of molar 
series, 5-4 1n. Length of three premolars, 23 in. Width of palate anteriorly and 
posteriorly, 2°9 in. Height of cranium from middle of palate, 4°2 in. Breadth 
of ditto in front of premolars, 4° in. 
Figs. 2 and 2 a.—Another fine specimen of cranium, showing occipital 
condyles and foramen, palate and five back molars on either side, both 
horn-cores, and a portion of right horn. The remarkable triangular 
form of the horn-core is well shown.—B.M. No. 16,411. 
Length of fragment, 14°4 in. Height of occipital facet from lower border of 
occipital foramen to summit of occipital crest, 4*8 in. Between extreme points of 
occipital crest, 8°8 in. Breadth of cranium beneath cores, 4°6 in. Breadth of 
cranium at post. angles of orbits, 8-8 in.» Length of core from roughness on frontal 
bone, 11:3 in. Base of the triangular core ant. surface (at origin), 3-9 in. Base of 
the triangular core ant. surface (at broken end), 3: in. Diameter of occipital
