Carapace much depressed, strongly tricarinate; anterior border 
serrated, posterior border expanded and very strongly serrated, 
each marginal being acutely pointed. Vertebral shields broader 
than long, about as broad as the costals ; nuchal moderate, trapezoid, 
broadest and emarginate posteriorly. Plastron large; the width of 
the bridge about equals the length of the posterior lobe, which is 
broadly notched; front lobe openly emarginate anteriorly. As 
regards size, the plastral shields take the following order, com- 
mencing with the largest: abdominals, femorals, pectorals, humerals, 
anals, gulars; no axillary or inguinal shields. Beak strongly 
hooked, not notched ; the width of the mandible at the symphysis is 
less than the diameter of the orbit. Tail a little longer than the 
head. Yellowish brown above, speckled with brown and with 
traces of black lines following the dorsal keels; plastron blackish 
brown, with a yellowish band on each side, which separates the 
blackish colour of the bridge from that of the rest of the plastron. 
Length of carapace 10 centim.
