 culating surface. — B.M. 



Length of fragment, 9"2 in. Width of lower extremity, 5 - 3 in. Anteroposterior 

 diam. of lower extremity internally, 4- 3 in.

Width of articulating surface, 4-3 in. Chord of sigmoid cavity, 2 - 4 in. 



Figs. 7, 7 a, 7 b, and 7 c. — Upper end of ulna, Avith entire radius. — - 

 B.M. 



Extreme length of conjoined radius and ulna, 153 in. Length of radius from 

 upper siu'face to styloid process, 11-3 in. Width of upper extremity of radius, 

 4 - in. Width of lower extremity of radius across epiphysial line, 4 - in. Circum- 

 ference of radius in centre of shaft, 5 '5 in.

Plate LXXVIII. 



Bones of Posterior Extremity of divers Fossil Indian Species of 

 Rhinoceros. 



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

 hills. The figures are copied from drawings by Messrs. Baker and 

 Durand, in the Journ. Asiatic Soc. for Aug. 1886, 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 - 5 in. ; from head to bottom 

 of third trochanter, 17"7in. Breadth from head to most salient point of o-reat 

 trochanter, 10-6 in. Breadth across condyles, 6'82in. Diameter of articulating 

 head, 4-65 in. Antero-posterior diameter of inner condyle, S - 45 in. ; antero-pos- 

 tcrior diameter of outer, 635 in.

Extreme length of fragment, 1T5 in. Width across third trochanter, 6- in. 

 Circumference below third trochanter, !)-j in.
