Apical shell nearly circular, cut by four deep notches, forming four triangular lobes: lobe on convex side is slightly longer, lobe on concave side truncated and two lateral lobe. External surface appears smooth under optical microscope but papillated at higher magnifications. Anterior aperture subcircular, slightly depressed and oblique.
Depth range based on type locality (Ref. 3442); to be replaced with a better reference.
