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 Palceindicus (Falc. 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. 



Fig. 4. — Fragment of cranium, showing occiput, foramen magnum, 

 condyles, and horn-cores. — B.M. No. 39,717. 



Figs. 5 and 5 a. — 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. 39,715. 



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. (Falc. and Caut.), from the Sewalik hills. 



Figs. 1 and 1 a. — 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, 1S'2 in. Great diameter of core, 4- in. Breadth of cranium 

 at post, angles of orbits, 8 - 7 in. Great diameter of orbit, 2 - 7 in. Length of molar 

 series, 5'4 in. Length of three premolars, 2 3 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 # S 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, 113 in. Base of the triangular core ant. surface (at origin), 39 in. Base of 

 the triangular core ant. surface (at broken end). 3 - in. Diameter of occipital
