Giimbel and Geinitz say Dreissena carhonaria. King's Anthracosia occurs in Nova Scotia only in the Lower Coal of Baddeck, C. B. Naiadites have both thick and thin shells; an external ligament; no teeth; have not been found in strictly marine limestones, nor in company with proper marine shells, and were probably attached by a byssus to sunken or floating timber; probably were all brackish or fresh water shells, like the Mytilidce and embryonic JJnionidm.
