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