 Mas. nost. Common on all sandy coasts. 



Shell often an inch in length, and seven or eight in breadth, a 

 little obliquely sloping at one end and rounded at the other, di- 

 vided diagonally into two triangles, one of which is faintly striate 

 transversely and the other longitudinally and marked with purple 

 bands. 



The variety resembles the Solen Ensis, but is much flatter and 

 larger, and longer in proportion in the breadth.
