Very closely allied to C. scripta, and resembling the var. elegans 
in coloration. Differs in the following points :—Carapace less dis- 
tinctly rugose, almost smooth in the adult; head of adult larger ; 
the width of the interorbital space equals the horizontal diameter of 
the orbit, which also equals the width of the mandible at the 
symphysis. The coloration of the upper surface of the carapace 
and of the soft parts agrees in every respect with that of C. elegans, 
but the underside of the shell is different. A large irregular dark 
brown or black blotch covers the greater part of the plastron ; bridge 
blackish, which colour extends as festoons to the lower surface of 
the marginals. 
Length of shell 21 centim.
