Description
editThe shape of the shell is conical. It has a peripheral carina and sharp, collabral axial riblets. There is no microsculpture. All whorls possess midwhorl angulation. Spiral lirae are present on some whorls. The shallow posterior sinus has a V-shape. The anterolateral sinus forms a channel. The basal sinus is present. There is no columellar sinus. The aperture has a rhomboidal shape. The columellar tooth is present. There is no umbilical septum.
Radula: the rachidian tooth is higher than broad and has lateral wings reduced or absent. The lateral tooth cusp is narrow. There are less than 10 marginal tooth pairs.[2]
