678 PLIOCENE MOLLTTSCA. 



Dimensions. — L. 20 mm. B. 16 mm. 



Distribution. — Not known living. 



Fossil : St. Erth. Coralline Crag : G-edgrave, Broom Hill, 

 Ramsholt. Waltonian : Walton-on-Naze, Beanmont, Little Oakley. Newbournian : 

 Walclringfield. Butleyan : Butlej. 



Remarks. — The specimen here figured corresponds with Wood's specimen of 

 the var. consors. It is always smaller than the type, and shorter in proportion to 

 the size of the shell. Wood figures one of them with an operculum in situ. The 

 callus on the inside lip is not so large.
