Carapace moderately depressed, regularly ovoid in outline, obtusely 
keeled in the young, smooth in the adult; posterior margin not 
serrated ; vertebral shields much broader than long, at least as 
broad as the costals; nuchal narrow. Plastron large, truncate 
anteriorly, feebly emarginate posteriorly ; the width of the hind 
lobe is less than two thirds that of the carapace ; the width of the 
bridge about equals the length of the hind lobe; the longest 
median suture is that between the abdominals, the shortest that 
between the humerals or the pectorals; suture between the anals 
a little longer than that between the femorals; axillary and 
inguinal shields large. Head moderate ; interorbital space very 
narrow; upper jaw not hooked, emarginate mesially; alveolar 
surface as in C. picta (?); the width of the mandible at the 
symphysis much less than the horizontal diameter of the orbit. 
Digits webbed to the claws. ‘Tail one third or one fourth the length 
of the shell. Carapace dark olive-brown, with a narrow yellow 
border and a wide-meshed yellowish network ; plastron and lower 
surfaces of marginals yellow; one or two oval black spots on the 
bridge, and some others on the neighbouring marginals. Head and 
neck dark olive-brown, with yellowish lines, the two widest of 
which extend from the nostril to the lip, below the eye, and from 
below the eye to below the ear respectively ; limbs marbled with 
yellow. 
The shell reaches a length of 25 centim.; the specimen in the 
collection measures only 101,
