Cyrena Duchastelii, Nyst : 1838. The following marine shells occur mixed with the freshwater species above enumerated: Buccinum undatum, Littorina littorea, Nassa reticulata, Purpura lapillus, Tellina solidula, Cardium edule, and fragments of some others.
Steenstrup noticed, in the north of Europe, that these mounds consisted nearly entirely of the shells of edible species, such as the oyster, mussel, and LITTORINA LITTOREA; that they were all those of adult specimens, but not all subject to similar conditions of existence or native to the same waters.
At the distance of a few yards, and in the same position, but a foot or two deeper, were observed marine shells, Cyprina islandica, Astarte elliptica, A. compressa, Fusus antiquus, Littorina littorea, and a Balanus. The height above the level of the sea was between 100 and 103 feet.
