 Brit. Carb. Lamell., pt. v., p. 419, pi. xlvii., ligs. 5-7 a. 



Our specimen is a cast of a left valve and part of the right, 

 preserved in a limonitic sandy matrix. The surface of the cast 

 next the shell is smooth and shows the sulcate ornament very 

 clearly. The valve is somewhat straight on the ventral edge, 

 gibbous in front of the beaks, and compressed behind. It compares 

 very closely with the above species.

A large specimen, which must have measured 16 cm. in length 

 when complete, occurs in the present series. It is an internal
