6 CHELONIA. 



R. 1419. The proximal extremity of the second right costal. 



R. 1421. The imperfect distal extremity of the eighth right costal. 



R. 885. Slab of sandstone showing the dorsal aspect of the distal 

 extremities of three costals, of which the third is very 

 imperfect. 



R. 1422. The distal extremity of a late costal of the left side. 



R. 1423. The postero-external extremity of the left hypoplastral of 

 a large individual. The three terminal processes, of which 

 the lower one has lost its extremity, are well shown. 



R. 1424. A similar specimen from the opposite side of a still larger 

 individual. 



R. 1425. A similar specimen from the right side of a smaller indi- 

 vidual. This specimen indicates a carapace about two 

 feet in length. 



39829. The right hypoplastral, wanting the outer extremity, of a 

 half-grown individual. Noticed by the writer, op. cit. 

 p. 203, where it is incorrectly said to be adult. This 

 specimen is almost indistinguishable from the hypoplastral 

 of a recent specimen in which the length of the carapace 

 is 0,468 (18-5 inches). 



R. 1428. The distal extremity of the right humerus of a large 

 individual. The transverse diameter is 0,066 (3*6 inches) 

 against 0,036 (1 # 43 inches) in the corresponding bone of 

 the above-mentioned skeleton. This specimen differs 

 from all recent examples in the Museum by the conversion 

 of the ectepicondylar groove into a foramen, but this can 

 scarcely be considered a specific character. The character- 

 istic ectepicondylar cbannel on the shaft is shown. 



The following specimen is from the Pliocene Situcdils of the 

 Punjab, India. 



R. 1418. The distal extremity of the second left costal of a large 

 individual. Other specimens from the same locality are 

 recorded by the writer, op. cit. p. 208, but the species is 

 now unknown in the Indus basin. No history. 



The following specimen is said to be from the Shvaliks of Burma. 



44824. The distal half of a costal bone.
