OF THE SIVALIK HILLS.

external process for embracing the cuneiform bone of the carpus as the 

 existing Camel. 



The carpal bones are equally correspondent both in form and number— 

 the small bone in rear of the os magnum and connected bone having the 

 same marked and spherical headed articulation with the scaphoid. 



We now come to the metacarpal bone, of which we have a very per- 

 fect specimen attached to the end of the radius and ulna by the interme- 

 diate carpal bones. We see no difference in form and no peculiarity requir- 

 ing remark. We derive data however from this for establishing the com- 

 parative size to which the Sivalik Camel arrived— our dimensions are placed 

 in juxta-position with those of a full grown and common sized Camel of the 

 present day :

The extent of non-anchylosis, and the form of the pullies for articula- 

 tion with the phalanges, and the phalanges themselves, appear to corres- 

 pond, and to be equally characteristic in both the fossil and the living 

 Camel. 



With the posterior extremities we are not so well provided, and shall 

 content ourselves with a reference to the femur only, of the lower end of 

 which bone we possess a variety of specimens ; of the largest of these we 

 annex the dimensions :
