Plate LXXVIII. 



Bones of Posterior Extremity of divers Fossil Indian Species of 



Ehinoceros. 



Figs. 1, la, and 1 b. — Femur of fossil Rhinoceros from the Sewalik 

 hills. The figiu-es are copied from drawings by Messrs. Baker and 

 Durand, in the Journ. Asiatic See for Aug. 1836, vol. v. p. 499. 

 The specimen was found in close proximity to the humerus and radius, 

 Plate LXXVII., fig. 1, so that there could be no doubt that it belonged 

 to the same animal. It is perfect except at the lower part of the gi-eat 

 trochanter. The fossil has a greater development in its anterior, and a 

 somewhat less development of its posterior, extremity, than in the Indian 

 Ehinoceros, but the difference is not excessive. The third trochanter 

 also differs from the existing species, as figured in Cuvier's ' Oss. Foss.,' 

 in not possessing the double point, for it has a single well-defined 

 ascending process, without any sign of the bicuspid termination (See 

 antea, p. 164).

 head, 4-66 in. Antero-posterior diameter of inner condyle, 8'45 in. ; antero-pos- 

 terior diameter of outer, 6'35 in.

Extreme length of fragment, 11-5 in. "Width across third trochanter, 6- iji. 

 Circumference below third trochanter, 9'6 in.
