Very closely allied to the preceding. Vertebrals 2 to 4 hex- 
agonal, the antero-lateral and postero-lateral borders subequal in 
length and sinuous. Coloration very similar, but the yellow borders 
to the dorsal shields are narrower and do not form a band right 
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.
