 Shell oblong, very convex, black. Back three-keeled, the

 ginal plates narrow, 25. The nuchal plates short, broad, 

 dilated behind. The sternum flat, keeled on the sides, 

 rounded and slightly produced in front, bluntly and broadly 

 nicked behind. The animal black. The head moderate, with 

 a narrow yellow streak from the hinder angle of each eye, 

 extending along, and coming closer together on the back of 

 the neck, where there is a central streak between them 

 and some other yellow streaks on the side. The tail mode-

 in that shell, even in the young state, the vertebral plates are 

 long sexangular, and the hinder margin is deeply serrated.
