FAUNA ANTIQUA SIVALENSIS. 



The carpal bones are equally correspondent in form and 

 number — the small bone in rear of the os magnum and con- 

 nected 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 perfect specimen attached to the end of the radius and 

 ulna by the intermediate carpal bones. We see no difference 

 in form, and no peculiarity requiring remark. We derive 

 data, however, from this, for establishing the comparative 

 size to which the Sewalik 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 pulleys 

 for articulation with the phalanges, and the phalanges them- 

 selves, appear to correspond, 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 femiu' 

 only, of the lower end of which bone we possess a variety of 

 specimens. Of the largest of these we annex the dimensions :

With the exception of the proximity of the condyles to 

 each other in the fossil, there i's no marked difference ; all 

 the hollows and protuberances on the bone of the existing 

 animal have their corresponding ones in the fossil. The 

 femur, in its length, also appears to have had as great a 

 curve forward as we observe in that of the Camel of the 

 present day. 



This brings us to a conclusion on the comparative differ- 

 ences between the Camehis Sivalensis and the Camelus drome- 

 clarius now existing. Although the fossil fi-agments from
