SIVATHERIUM GIGANTEUM. 



275 



The articular head of the body is very convex and broad a.nd less 

 pointed downwards than in the ox ; its general direction being also 

 more vertical. The length of the body is very short for the other 

 dimensions.

From near Nahun. This probably came from the same place as the 

 three last. — Joiirn. As. Soc. vol. vi. p. 899. 



No. SSi. — Mutilated specimen of vertebra (either, last cei-vical or 

 first dorsal) presenting the greater part of the body with the articular 

 surfaces entire, but the neural arch and apophyses broken off; less 

 mutilated on the right side than on the left, and it is there seen that there 

 was no vertebral foramen : the posterior articulating sitrface shows, 

 on its right margin, the smooth depression of a costal articulation : the 

 anterior articulating surface is very large, globular, and projecting ; the 

 posterior shows a deep cup, which is oblique in its vertical direction, 

 indicating that the bone is probably the last cervical. Too much 

 mutilated to furnish any dimensions. From the Sewalik hills. 

 Presented by Conductor Dawe. — Journ. As. Soc. vi. 899. 



No. 335. — Lower end of himierus left side, showing the whole of the 

 articular head with only a short portion of the shaft. Shaft continuous 

 with the inner condyle, the outer condyle projecting outwards with 

 great obliquity as in the rhinoceros. The outer condyle shows 

 mai'kedly the projecting ridge bisecting its articulating surface, as is 

 normal in the ruminants.

No. 336. — Fragment comprising the upper half of the anti-brachium 

 right side, showing a considerable portion of the shaft and the whole of 

 the articular surface of the radius, which is entire ; the olecranon 

 broken olF; a small splint of the ulna adhering to the shaft. The 

 articular surface of radius shows the depressions for the corresponding 

 surface of the humerus ; the inner is large and nearly circular, inclining 

 obliquely inwards to a lower level than the outer. The outer side of 

 the bone is marked by a salient tuberosity. Shaft contracts rapidly 

 from the articular surface, and, in front, immediately below the outer 

 articular surface, there is a deep rough pit.
