culating surface.—B.M.

Puate LXXVIII. 
Bones of Posterior Extremity of divers Fossil Indian Species of 
Rhinoceros. 
Figs. 1, 1a, and 1 .—Femur of fossil Rhinoceros from the Sewalik 
hills. The figures are cepied from drawings by Messrs. Baker and 
Durand, in the Journ. Asiatic Soc. for Aug. 1836, vol. v. p. 499. 
The specimen was found in close proximity to the humerus and radius, 
Plate LXXVIL., 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 great 
trochanter. The fossil has a greater development in its anterior, and a 
somewhat less development of its posterior, extremity, than in the Indian 
Rhinoceros, 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. 
Length from head to bottom of inner condyle, 24°5in.; from head to bottom 
of third trochanter, 17°7in. Breadth from head to most. salient point of great 
trochanter, 10°6 in. Breadth across condyles, 6°82in. Diameter of articulating 
head, 4°65in. Antero- ~posterior diameter of inner condyle, 8°45 in. ; antero- -pos- 
terior diameter of outer, 6°35 in. 
Figs. 2 and 2 a.—Mutilated fragment of upper end of femur.—B.M. 
Extreme length of fragment, 115in. Width across third trochanter, 6 in. 
Circumference below third ‘trochanter, 9°5 in.
