The operculum is circular and shows yellow to brown colors[3][4][5][6][7][8] (Original description W.H.

Dall) Shell in general features recalling Gaza daedala, much of whose description would apply with little change to this species.

The umbilicus is bordered by an edge from which the flattened base falls away, and with straight walls forming an almost perfect cone.

The columella is callous above, thinly and unevenly reflected half-way across the umbilicus, gently and very obliquely descending and smoothly passing into the basal part of the lip.

The interior of the aperture, the lip, the umbilical callus, and a slight wash near the sutural junction, are brilliantly nacreous.

The upper surface of shell is distinctly tinted with fawn color, the base is waxen white, the nacre perceptible through the thinner portions.
