284 FAUNA AISTIQUA SIVALENSIS. 



sho-ndng only occipital and part of sphenoid, too defective for further 

 determination. 



iVo. 607. Bos ? — Skull nearly complete from the occipital con- 

 dyles on to the diastema, Avith two lines of molars, both orbits and the 

 right zygomatic arch; both horn-cores broken off, and the upper 

 lamina of the frontal bone denuded, so as to afford no characters in 

 that part. The skull is nearly of the same size as 574. The molars 

 are i'ar advanced in wear, and show the compressed accessory pillar 

 between the barrels, exactly as in 572. Eime of orbits more or less 

 damaged, but the left shows the great vertical height seen in 572. 

 From Sewalik hills, sandstone matrix. 



II. — Description by Dr. Falconer of Fossil Species of Bos 



FROM THE NeRBUDDA, IN THE MuSEUM OF THE AsiATIC SOCIETY 



OF Bengal. 



No. 18. Bos PalcEindmis.— Cvani-um with the cores of 2 horns 

 attached, broken off in front across the orbits, where it is much muti- 

 lated ; occiput, right condyle, and left styloids, with the occipito-sphenoid 

 region and zygomatic fossa on either side nearly entire. Core of right 

 horn in 4 pieces, extending nearly to the apex. Left core in 3 pieces, 

 of less extent. Dimensions — Length of right core 2 feet 9 in. ; breadth 

 at base 6^ in. ; thickness 4;^ in. Length of left core 1 foot 11 in.; 

 breadth of skull at base of occiput 13 in. ; ditto from occipital condyles 

 to plane of frontal 10 in. The horn-cores spread out more horizontally, 

 and Avith a less incHnation upwards than in the existing wild buffalo, 

 slightly concave anteriorly and convex behind. A cord stretched 

 between the tips would subtend the plane of the cranium behind the 

 frontal. In all 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. The posterior border of the cores 

 encroaches much upon the temporal fossa, which is narrow. These 

 characters are so constant, as shown by still better specimens in the 

 British Museum, that there can be little doubt that the species is dis- 

 tinct from the existing wild buffalo. The specimen is in a soft friable 

 condition, and covered with calcareous matrix ; probably belonged to 

 an adult male of large size. This fine specimen has remained unfigured 

 in the Journal. It would appear to have been the intention of Mr. 

 J. Prinsep to have described and dra^vn it; this he postponed, ex- 

 pecting similar specimens from Conductor Dawe. His subsequent 

 fatal illness prevented this design from ever being carried out (vide 

 Jour. As. Soc, vi. 489). Found by Dr. Spilsbury, near Sagauni (or 

 Sejouni). 



No. 19. Bos Palmndicus. — ^Mutilated cranium broken off across the 

 orbit with the base of the left core attached, ths right core with the 

 parietals and vertex broken off. Occiput nearly entire with the con- 

 dyles, occipito-sphenoid region and right styloid and mastoid entire, 

 together with the left temporal fossa. Width of core at base 6-^ in. ; 

 thickness 4^. Width between the outer marram of occipital condyles
