Neural plates hexagonal, anterior lateral margins shortest. Plas- 

 tron extensively united to the carapace by suture, with short axil- 

 lary and inguinal buttresses, just reaching the first and fifth costal 

 plates ; eritoplastron anterior to the humero-pectoral suture. Skull 

 with a bony temporal arch ; alveolar surfaces very broad, that of 

 upper jaw with a strong tuberculate median ridge ; edge of jaws 

 strongly toothed ; choanae behind the level of the eyes. Upper 

 surface of snout and crown covered with a single shield, behind 

 which the skin is corrugated. Digits extensively webbed. Tail

Carapace moderately depressed, with a strong, interrupted, 

 tubercular keel in the young, which becomes fainter in the adult ; 

 margin not serrated ; nuchal narrow ; first vertebral not or but 

 little broader anteriorly than posteriorly, lateral borders usually 

 sinuous ; second, third, and fourth vertebrals broader than long 

 or as long as broad, narrower than the costals. Plastron large, 

 angulate laterally, truncate anteriorly, notched posteriorly ; the 

 width of the bridge exceeds the length of the hind lobe ; the 

 longest median suture is that between the abdominals ; suture 

 between the gulars as long as that between the humerals or 

 shorter ; axillary and inguinal large. Head moderate ; snout 

 short, obtuse ; upper jaw notched mesially, denticulated ; lower 

 jaw strongly serrated, flat beneath, its width at the symphysis 

 equalling the diameter of the orbit. Scales on limbs small ; digits 

 broadly webbed. Tail very short. Carapace brown, each shield 

 of the disk with a large central blackish ocellus encircled with
