Carapace muuh depressed, strongly tricarinato ; 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. Eeak 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.
