Three upper whorls (especially the penultimate) show radially sculptured sutures. The two keels are margined accordingly. The penultimate whorl is longitudinally oblique. The body whorl is bicarinate. Between the sutures the shell is radially obliquely adorned with margined keels. The base of the shell shows five spiral irae. The aperture is round with an iridescent interior.[3]
