Venus Borealis : testa lentiformi : striis transversis membranaceis 



erectis remotissimis. Gmel. Linn. Si/st. Nat, 

 T. I. p. 6. p. 3235. sp. 77. 



This is a scarce, or very local shell on the British coasts, and seems 

 to agree with the description of the Linnasan Venus borealis. The 

 species was unknown to Da Costa, and is different from that which 

 Mr. Penant describes under the same name.
