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 much broader than long, at 

 least as broad as the costals ; first vertcbi-al broader than long and 

 somewhat narrower than second. 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 

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

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

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

 the marginals longer than that between 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 webbed, elawp long, curved, sharp. Front part of arm with 

 broad, band-like transverse shields. Carapace reddish brown, or 

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