its upper or flut valve, and had been the means of its being 

 dragged by the tide many hundred yards, to the place where it 

 lay. The " roots '' of the Luininarui shelt<'red a Pecten vctriiut 

 and sevonil small crabs ; and a young Anomia and small flat Tuni- 

 catn were fixed on the lower vidve. 



Mijtilus edulis, L. Kather email and not gregarious. Lines of 

 increase (juite distinct. 



barlmtus, L. Generally of a bluish colour, sometimes purple. 



aflriatic>t.<<, Lam. In pebbly ground these rather thin shells 



fasten together the surrounding small stones, as if for protection. 



Alodlolaria discors, L. 



Nxcula uuvleus, L. 



Pfctunculiis (/Ii/rifmeris, L. Common, but rather small, being seldom 

 more than 14 inch in diameter. At verj- low tides I have seen 

 this edible 8|)ecies picked up by hundreds. On emerging from the 

 sandy gravel it does not lea]) like a Cardium, but crawls slowly, 

 leaving a small furrow behind. \\'hite specimens are rare, also 

 pinkish or mauve-coloured ones. 



Area lactea, L. Under stones, and once with Rissoa lactea rather 

 deeply buried. 



tetrar/oiia, Poli. 



Lasasa rubra, Mont. 



, var. pallida. 



Loripes lacietts, L. 



Lucina horealis, L. SmaU. 



Axiniis Jli'.xiiosus, Mont. Dead shells only ; separate valres rather 

 common in St. Aubin's Bay. 



Diplodonta rotunddta, Mont. One valve only. 



Cardium echimitum, L. Verj' fine specimens with spines perfect, in 

 muddy sand in St. Aubin's Bay at low water of equinoctial spring- 

 tides. Like many other bivalves they emerge out of the sand 

 when the tide begins to rise. I believe they come out more 

 numerously when a bright sun warms the surface ; but if a heavy 

 shower happen to fall, few, if any, will appear. 



tuberculatum, L. Living with the preceding some years ago 



(Mr. Piquet) ; lately I have found only dead shells, but fresh- 

 looking. 



exiguum, Gmelin. 



nodosum, Turt. Gregarious in sand, the white, the yellow, 



and the pink liWng together. 

 , var. rosea. Lam. 



ednle, L. 



norve'jicum, Spengl. Of a light colour at La Roc()ue in shelly 



gravel ; dark olive in muddy sand in St. Aubin's Bay. 



, var. pallida. 



Astarte triangidaris, Mont. Gregarious in fine shelly gravel at low 



water of spring-tides. 

 Circe minim/i, Mont. Valves only. 

 Fentts exohta, L.
