). Shell fragile, elongate, with nearly parallel sides (Fig. 75C). Only 1 whorl visible, forming the entire shell. At its apical end, the aperture bends over the apex of the shell and the parietal wall forms a blunt prolongation that completely covers the apex. There is a narrow apical umbilicus (Fig. 75D). Anterior end of the shell rounded. Umbilicus closed. Aperture long, wide anteriorly, narrowing gradually at about 1/2 of its length. Columellar margin thickened near the anterior end of the shell. Sculpture of numerous, faint and densely concentrated spiral grooves crossed by fine growth lines all over the shell surface. Colour uniformly shiny whitish.
