HEY : YORKSHRS MARINE SHELLS. 



Artemis exoleta L. 



Very scarce on the Yorkshire coast. I have taken it at 

 Redcar, and seen it from Scarborough. 

 Artemis lincta Pult. 



Abundant off Coatham and Redcar. After rough weather I 

 have seen the beach from Coatham Pier to the Tees Breakwater 

 Hterally covered with Hving specimens of this species. 

 Tapes virgineus L. 



This famiUar south-coast species is seldom taken off this 

 coast. I have once met with it at Redcar, and it has been got 

 also at Scarborough. 

 Tapes puUastra Mont. 



Common everywhere, along with its variety perforans Mont. 

 Lucinopsis undata Penn. 



Not nearly so abundant, I think, as it was ten years ago. At 

 that time its numbers on Redcar beach almost rivalled those of 

 A. lincta. 



C YFRINIDAL. 



Cyprina Islandica L. 



Cast up alive in quantities after heavy weather all along the 

 beach from Saltburn to the Tees mouth. Also at Filey. 

 Astarte compressa Mont. 



The valves picked up on Bridlington beach are perhaps fossil, 

 but Bean used to dredge it in deep water off Scarborough. 



CARDIID.E. 



Cardium echinatum L. 



I have taken fine specimens from the fishermen's lines at 

 Redcar. When cast up on the beach the spines are usually 

 rubbed off. 

 Cardium edule L. 



There are extensive Cockle beds in the mudflats by the Tees. 

 Cardium nodosum Turton. 

 Cardium Norvegicum Spengler. 



Specimens of both these species are in Scarborough Museum, 

 labelled 'Scarborough.' 



CARDITID.^. 



Cyamium munitum Fab. ^ 



Among seaweed near low-water mark at Scarborough. 



LUCINID/E. 



Lucina borealis L. 



Mr. Roberts, of Scarborough, tells me this species has been 

 frequently dredged there.
