This beautiful species, which was not observed in the drift beds until found in Ireland by Captain James, is intermediate in its character between Fusus scalariformis and Fusus Barvicensis. It has the general form and ventricose whorls of the former, with the fimbriated ribs of the latter. In the above cut, from a drawing by Mr. W. Bailey, specimens of natural size are represented by the two uppermost figures, and magnified views by the two lower.
