M. with an oval fhell, of a dirty-white colour, very 

 finely ftriated tranfverfely, and marked with broad and 

 narrow glaucous rays : the anterior end wrinkled : the 

 the beaks reflect backwards, with a narrow gape between 

 them. Length ufually two inches and a half; breadth 

 three and a half. 



On the authority of Mr. Donovan this is added to 

 the Fauna of BritiJJi Shells ; who informs us, it was dil- 

 covered by Mifs Pocock in i8ci, on Hale fands, under 

 Lelant in Cornwall. It is probable thefe extenfive fands 

 may be very produftive at times^ but we mufl confider 

 this lady as extremely fortunate; for in our vifits to 

 that part of the CorniJIi coaft, efpecially lately at the 

 place mentioned, and about St. Ives, no fuch fliell was 

 to be found, although Venus Chione was plentiful, and 

 which was brought to us by the fifliermen for M .glauca, 

 not knowing the diiference : this may account for their 

 faying this fliell is at times found on that coaft in plenty. 



The very good figure given in the Britijh Shells, is 

 confideral'ly larger than is ufually defcribed, meafuring 

 three inches and a half, by four and a half.
