106 CHELONIA. 



39842. The crushed shell of an individual agreeing nearly in size 

 with the preceding; from the Siwaliks. The carapace 

 has been crushed in, and many of the component bones 

 are dislocated, although the two extremities remain nearly 

 entire. The plastron, although split in the median line, 

 is entire, and the cutting of the entoplastral by the 

 humero-pectoral sulcus is shown. Cautley Collection. 



R. 329. Fragment of the right side of the shell of an individual 

 very nearly as large as the preceding ; from the Siwaliks. 

 The specimen shows the 1st costal, 4 marginals, and por- 

 tions of the hyo- and hypoplastrals. 



Transferred from the Indian Museum, 1880. 



R. 829. The imperfect plastron of a very large individual, in matrix ; 

 from the Siwaliks. The epiplastrals are imperfect ante- 

 riorly, and only small fragments of the xiphiplastrals 

 remain. The humero-pectoral sulcus is seen cutting the 

 entoplastral. Cautley Collection. 



R. 1585. The 5th and 6th left costals of a young individual, show- 

 ing the insertion of the inguinal buttress; from the 

 Siwaliks. Cautley Collection, 



Genus BELLIA, Gray \ 



The shell has the same general structural features as in Damonia, 

 but the neural bones of the adult (fig. 23) are not distinctly cari- 

 nated, and the vertebral shields have a more or less decidedly 

 balloon-shaped contour. The nuchal shield may be absent. The 

 skull is readily distinguished from that of Damonia by the forward 

 position of the posterior nares. 



Bellia sivalensis/Theobald 2 . 



Syn. Clemmys sivalensis, Lydekker 3 . 

 Clemmys liydaspica, Lydekker 4 . 



Carapace moderately depressed, without' distinct carina?, and with 

 the vertebral region flattened in the adult male ; no nuchal shield ; 

 1st vertebral shield pentagonal, much narrower behind than in 

 front.
