242 LIVERPOOL MARINE BIOLOGY COMMITTEE REPORT. 



Cyprina islandica hds, not unfrequently, been found alive 

 in the channels between banks of the Lavan Sands, off 

 Llanfairfechan (probably cast out from some of the seagoing 

 hookers as they are cleaned up while running in to Bangor). 



In one such shell was found a fine specimen of Mala- 

 cobdeUa grossa. A workman at Penmaenmawr, who ate 

 Cyprina, was said to have been badly " mussellcd." 



Venus lincta, Pult., and F. exoleta, L. Valves occur at 

 Penmaenmawr. 



Venus fasciata. Common at low-water, at Beaumaris. 



Tapes virgineus occurs on the beach at Penmaenmawr 

 and ColwyU; and dredged off Llandudno and Conway. 



Tapes pullastra is common on the same beaches, but I 

 have not found its habitat (D.). 



Tapes decussatus. The like remarks as to this. Large 

 valves occurred in a kitchen midden on the Ormes Head, at 

 Gwyfyd, near Llandudno. 



Lucinopsis undata, Penn. Occurs fresh, but without 

 the animal, at Penmaenmawr. 



Tellina crassa, valves found at Colwyn Bay. 



Ceratisolen legumen and Solen vagina, both species some- 

 what localised occur in abundance and well grown in the low 

 water channels below Penmaenmawr. The former, and a 

 small form of Solen ensis, very abundant at Southport. 



Mactra stultorum. Very common and large at South- 

 port and Blackpool, where they used to be eaten boiled or 

 raw. Sometimes immense quantities of young shells are 

 cast up along high-water mark, quite fresh, but without the 

 animals. 



Solen pellucidus is dredged fine in Conway Bay, four to 

 six fathoms. 



Thracia convexa, dead valves occur occasionally on the 

 beach at Southport. I have dredged fresh valves (but not 

 the mollusc) off Whitehaven (D.).
