Yerj' closely allied to the preceding, Vertebrals 2 to 4 hex- 

 agonal, the antero-lateral and postero-lateral borders subequal in

 across the back ; a large symmetrical blackish marking is usually 

 present on the plastron and extends from the gulars to the anals, 

 without producing any lateral branches anteriorly.
