 late visit to Cornwall,

 in foreign specimens: the front margin running in a straight line 

 without contraction in tlie middle : tiie anterior side marked with 

 about thirty longitudinal striae radiating from the hinge in an 

 oblique direction so as to cover three fourths of the surface, and 

 becoming gradually more distant as they recede towards the 

 opposite extremity; and at the termination of the striated side 

 are other raised oblique stria? passing in an opposite directidh*: 

 hinge central, with two teeth in each valve, one of which is Vfery
