This is a whitish, subdiaphanous shell, indistinctly 

 striated transversely, and marked within with two ob- 

 long red spots, or lines, which are continued more than 

 half-way down the shell ; the hinge has a double primary 

 tooth in the centre; the lateral teeth are strong and 

 remote. Length half an inch ; breadth five eighths of an 

 inch. 



Inhabits the European and American seas, and has 

 been noticed as English, by Da Costa, from the coasts 

 of Hampshire and Lancashire, and by Dr. Pulteney, 

 and Mr. Bryer, who found it on the shore, between 

 Weymouth and Portland. 



This species is subject to variation; sometimes it is 

 uniformly purple, or white, and sometimes rayed with 

 several red lines, in which state it is the var. P. of
