[2][3] This is an Eastern Pacific Ocean species which was previously known as Chlorostoma montereyi.

The seven whorls are flattened, encircled by numerous fine lirae, which become obsolete on the lower whorl, which shows usually very ill-defined obliquely descending small folds, at right angles to the incremental striae.

The columella is subhorizontal, curved, toothed below the middle, receding above, not spreading around the umbilicus as in some other species of this genus.

The umbilicus is funnel-shaped, rapidly becoming very narrow, white within, its edge defined by an angle.

[4] This species occurs in the Pacific Ocean off the coast of California, USA.
