This species is never, so far as we have been .able to learn, been eaten in America. It is inserted in this paper on account of its close relationship to the edible 'Cockle {Cardium edule) of Etirope ; without doubt it is edible, and is probably as good food as the European form, which it Tesembles closely in nearly all respects. The chief distinguish- ing mark between the two to the non-scientific observer is the smaller number of ribs, twenty-six, in Cardium edule, â C. Islandicum having thirty-six. The European Cockle lives on sand beaches and the banks â of estuaries. We are told in the Fisheries Exhibition Litera- ture that 'It is equally good, raw or cooked, and may be
