"Shell small, length 10 mm, form spindle-shaped with conical spire of 5 whorls which is approximately ½ length of the shell; protoconch small transparent, light, and round; the parietal callus extends along the columella up to the suture, it is semi-transparent and thus partially obscures the markings; pillar structure consists of 8-10 fairly equal plications which are set apart from the parietal callus by a shallow groove; these folds form a rather narrow vertical portion of the columella; general color light to dark gray; just below the suture on the body whorl is a very narrow gray spiral line that is connected to a lighter and wider spiral line by vertical bars; a light band separates this from the main portion of the whorl which is mottled gray with small scattered brown dots; the posterior band of the fasciole is decorated with bars or squares of brown, the remainder of the fasciole is white; the interior of the lip is dark brown; no evidence of an operculum. Length 9 mm; diameter 3 mm. (Holotype)". Recent. Two miles S of Aguachale, Baja California, Mexico.
