Description. Shell short, thick, ovate-conic; surface checked with waving folds and 

 spiral lines; lip thickened and toothed within; pillar with a broad and thick callus. 



The elevated lines which cross the undulating folds or ribs are most distinct on the ribs. 



Dr. Gould, in his work on the invertebrata of Massachusetts, says " specimens of this 

 shell are rare, only found to the south of Cape Cod, and usually have a chalky aspect." 

 It is not abundant on the Carolina coast, though often found recent upon our beaches. 

 In the Post Pleiocene beds it is a common fossil. We are inclined to believe those from 

 Massachusetts are also fossils from that formation.
