MARINE CONCHOLOGY.

ARC ID. ^. 



IJuciila Nucleus L. 



I have dredged this species off Cayton Bay. 

 Nucula nitida Sow. 

 ITucula tenuis L. 



Both at Scarborough (Scarborough Museum). 



MYTILID.^.. 



Mytilus edulis L. 



Everywhere on rocks and piles between tide marks — chiefly 

 the small form. On West Scar the fishermen had some 'mussel 

 preserves,' where they grew them to a large size for bait. 

 Modiola modiolus L. 



At the roots of seaweed, (Sic, attached by a byssus. So abundant 

 near Runswick Bay as to be used for bait. This is one of those 

 shells which appears capable of enormous development under 

 favourable circumstances. I have two specimens taken in deep 

 water off Bridlington, which measure each about six inches in 

 length. 

 Modiolaria nigra Gray. 



Redcar (Ferguson). 

 Crenella decussata Mont. 



Scarborough (Bean). 



PECTINID.^. 



Pecten pusio L. 



Not uncommon at Redcar. 

 Pecten varius L. 



Redcar. I have only taken small specimens. 

 Pecten opercularis Da Costa. 



Washed up on Redcar sands after very rough weather. Dredged 

 off Bridlington. 

 Pecten tigrinus Miill. 



Dead shells occasionally thrown up on Redcar beach. 



ANOMIID.E. 



Auomia ephippium L. 



Very abundant in its young state on other shells, such as Fusi^ 

 and on stones and seaweed. 



Marine Shells at Mablethorpe.— This small place on the Lincoln- 

 shire coast appears to be good hunting ground for the conchologist. A friend, 

 making a short stay, kindly collected for me a large boxful of shells, taking specimens 

 at random. The burrowing species, Solen, Mya, and PJiolas, were very plentiful, an 

 odd valve of PJiolas dactyhis measuring 4f inches. — W. Gain, Tuxford, Newark,
