Abstract
Dentalium martini Whitfield, 1882, is a calcareous worm tube, not a mollusk , and is placed in synonymy of Coleolus crenatocinctum Hall, 1879. The grow th of D. martini mimics logarithmic curvature in the holotype, but in other specimens shape varies from irregularly curved to straight. A prime reason for reassignment is variation of the wall thickness around the circumferen ce in D. martini, which in late Paleozoic and Recent scaphopods of the same size is of uniform thickness.
