Remarks All known specimens are very similar though some of the new specimens reach a larger size and have eroded axial lamellae. The radula ( Fig. 32 ) is rachiglossate with a rachidian tooth bearing a long, broad, central cusp, a small, lateral denticle and a moderately long, broad, lateral cusp. A small denticle is occasionally present between the central cusp and the lateral denticle. The operculum ( Fig. 31 ) is elliptical with a terminal nucleus.
