Shell rather more than an inch long, and the length and breadth 

 are nearly equal ; the colour is white, variegated with pale 

 reddish brown irregularly angulated spots ; the inside is 

 white, except under the umbones, where it is stained with 

 purple. In many respects V. reflexa of Montagu answers 

 to this species, but it is described with thin laminal ribs.

 pressed and beaked at the anterior end, gra- 

 nulated, and strongly marked with decus- 

 sated striae ; anterior slope striated, and the 

 posterior cordiform ; margin crenulated.
