This is a species of the fidicula group, white, small, roundly shouldered with rather coarse sculpture on the spire, which becomes obsolete on the last whorl: axial sculpture of (on the penultimate whorl 13) rounded irregular ribs with subequal interspaces, the ribs nodulate by the intersection of three or four rather strong spiral cords with narrower interspaces: on the last whorl the ribs are obsolete and the spiral sculpture feebler, flatter, and with occasional intercalary smaller threads: anal fasciole and sulcus obscure, aperture narrow, inner lip erased, canal short. Height of shell 8mm.; Height of last whorl 5mm.; diameter: 3.5 mm.

Sitka. Alaska, to Puget Sound.
