The shells of this genus inhabit, like the Solcasj 

 the sand of the sea shores, in deep and vertical pits, 

 and in such places as are bare at low tide ; their resi- 

 dences are generally detected only by a small dimple 

 in the sand; occasionally, however, they may be seen 

 with a part of their shells projecting above the sur- 

 face, and then they may easily be taken by intercept- 

 ing their retreat with a spade.
