PELECYPODA. 



Nuciila nucleus (L.). — Single valves common, E. ; B. R. ; Rye Bay. 

 var. radiata F. & H. — Several living, lof, E. ; valves, B. 



Nuculaim miniita Miiller.— Valves common, E. 



Anoinia ephippium L. — Young living on stones, B.R., large shells 

 sometimes washed ashore. Small aculeate and cylindrical varie- 

 ties occasionally in roots of Laminaria. 



Barbatia lactea (L). — Valves common, E. 



Mytilus edulis (L.). — Everywhere, Selsey to Rye. The largest mus- 

 sels come from the river Adur at Shoreham. Occasional speci- 

 mens from B.R. are light yellow in colour, and many are glossy 

 and beautifully rayed.

Volsella adriatica (Lam.). — A single living specimen, i2f., E. 



Afodlolaria niariiiorata Forbes. — 5f , B. ; valves, E. 



Ostrea edulis L.— Everywhere. At Selsey, they occur not in regular 

 beds, but scattered over a wide area in small numbers \ these 

 oysters are said to have originated in the wreck of a schooner 

 bringing Caen Bays to Southampton. The Shoreham oyster beds 

 consist chiefly of Portuguese (6>. angulata Lam.) with some O. 

 edulis and Americans ((9. virginica Gm.). 



Wild oysters are occasionally found at B.R. on chalk and flint, 

 and I have twice found var. parasitica Turton glossy, greenish, 

 and rayed, once on chalk, and once on Mytilus edulis at B.R.
