Carapace depressed, angular, the vertebral region flat, with an 

 interrupted obtuse keel ; posterior margin serrated ; six, rarely seven, 

 vertebral shields, the small additional shield intercalated between 

 the fourth and fifth ; vertebrals (except the first) much broader 

 than long, at least as broad as the costals. Plastron narrower than the 

 opening of the shell, hind lobe openly emarginate, connected with 

 the carapace by a distinct bridge, the width of which is contained 

 twice and a half to twice and two thirds in the length of the plas- 

 tron ; the hyo- and hypoplastral bones contribute to an equal 

 degree to the formation of tlie bridge ; no distinct transverse hinge ; 

 a large inguinal shield ; the suture between the pectoral shield and 

 the marginals longer than that bet\\'een the abdominal and the 

 marginals ; the median suture between the pectoral shields as long 

 as or a little longer than that between the abdominals. Hook of 

 the upper jaw bicuspid, divided by a median groove. Digits exten- 

 sively webljed ; claws long, curved, sharp. Front part of arm with 

 broad, baud-lilie transverse shields. Carapace reddish brown, or 

 yellowish brown with radiating brown lines ; young with a pair of 

 round black spots on each vertebral shield, and one or two similar 

 spots on each costal ; plastron yellow with brown spots, or brown 

 with the sutures between the shields yellow. Head yellowish 

 brown ; neck broAvn, with irregular yellowish streaks, the broadest 

 of which extends from the posterior corner of the eye.

Carapace depressed, with a single, obtuse keel ; posterior margin 

 serrated ; vertebral shields as broad as long or broader than long, 

 narrower than the costals. Plastron nai-rower than the opening of 

 the shell, hind lobe angularly notched, connected with the carapace 

 by a distinct bridge, the width of which is contained twice and 

 three fourths to three times in the length of the plastron ; the hyo- 

 and hypoplastral bones contribute in a nearly equal degree to the 

 formation of the bridge ; the transverse hinge between the hyo- 

 and hypoplastrals, which does not correspond with the curved 

 suture between the pectoral and abdominal shields, is only deve-
