APPENDIX TO THE CATALOGUE OE SHIELD REPTILES. 



1!) 



The young specimen has the two front shields rather 

 broader compared with the length than the others : and 

 the largest specimen has the fourth vertebral shield rather 

 irregular-shaped. This species differs from P. flaviventris 

 in the keel of the first three shields being pale and not 

 black, and much more indistinctly marked than in P. 

 tecta ; but is at once known by its strongly dentated 

 margin and by the three hinder marginal plates on eacli 

 side only occupying the hinder margin of the fifth vertebral 

 plate. In all the other Pangshwce the hinder margin of 

 the fifth plate only occupies the width of two and a half or 

 two and a quarter marginal plates.

 Punjab, where it is abundant, which show the permanence 

 of the characters assigned to this species.

Suborder III. Pleuroderes (p. 70). 



The genera of this group of Tortoises may be artificially 

 arranged by the sternal plates, thus : — 



1. Sterno-costal symphysis covered by the outer ends of 

 the pectoral and abdominal shields. 



A. Pectoral plates very large and long. Abdominal 

 plates short and transverse. Hydromedusa. 



B. Pectorcl plates four-sided, moderate, subequal. Hv- 



DRASPIS, CHELTMTS, and EuCHELYMYS. 



C. Pectoral plates triangular. Pelomedusa. 



2. Symphysis covered by the ends of the abdominal plates j 

 pectoral plates narrow, triangular. Sternoth.erus.

Fam. CHELYDIDJE (p. 70), add:— 



Skull very depressed ; basisphenoid elongate, triangular, 

 much broader behind ; basioccipital very narrow, elongate.

 row in front and broad behind ; basioccipital narrow, ratlin- 

 broader in front. (Wagler, Amphibia, tab. 8. fig. xxviii.) 



Some specimens in the British Museum (perhaps the 

 males) have the middle of the hinder part of the sternum 

 deeply conically concave, the front part being quite flat.
