Sculpture: the flat sutural shelf of the upper whorls is ornamented by fine regular radial riblets.

Obliquely descending the slope, these riblets crenulate the upper spirals and gradually vanish on the body whorl into faint irregularly spaced growth lines.

The body whorl is encircled by ten strong keels whose interstices are occupied by small and smaller threads as before.

The umbilicus is wide and deep, penetrated by five elevated spiral ridges beaded by longitudinal sculpture.

The peristome is entire, simple, and sharp, within brilliantly nacreous, nacre edged with a thin brown and a broader yellow non-nacreous margin.
