howeverj appears to have only met with dead fpeci- 

 raens, by his faying it is M^hitifli in its ground colour, "as 

 well as having no glofs v/ithin ; neither did he fecm ac- 

 quainted with its natural hillory. The latter author is 

 alfo filent on this head, and has followed Da Costa, in 

 flating it to be a produftion of the Dorfetjldre coaft, 

 the only place he ever received it from. We firft found 

 it in fand from Falmouth harbour, and Whitfand bay, in 

 Cornwall, not common, and all dead fpecimens ; and 

 afterwards in great abundance alive, in Salcovib bay in 

 Devonjhire : they always lie near the lowed water-mark, 

 adhering to loofe (tones, old oyjlers, and other {hells, 

 and are moftly obtained by dredging. 



It is alfo found fparingly on other parts of the fame 

 coaft, thrown upon the ftiores. We have received dead, 

 and much worn fliells, from Sandwich in Kent. 



It feems to be a local fpccies, and has not often been 

 obtained by colleQors in a recent ftate. 



Doftor PuLTENEY does not give it in his Catalogue 

 of Dorfet Shells, notwithftanding Da Costa received 

 it from tliat coaft, and has been found by Mr. Br ye 2. 

 .at Weymouth. 



Mr. Boys informs us, that altliough only dead fhells 

 are to be met with at Sandwich, it is found alive on the 

 nocks at Dover.
