A very thin, brittle, depressed shell, finely striated 

 transversely, and somewhat angular before. It varies 

 greatly in colour, being white, or red, or flesh-coloured, or 

 yellow, or variegated with different colours, disposed in 

 zones, over the surface of the shell ; the hinge has a single 

 bifid tooth in each valve. Length about half an inch, 

 breadth three quarters. 



Inhabits the European Seas, and is very common on 

 many of the sandy shores of Great Britain. 



This is a distinct species from the T. planata, of Lin- 

 naeus, with which it has sometimes been confounded. 

 It was discovered by Lister, who has given a very good 

 figure of the shell.
