Shell slenderly elongate-ovoid, shining, translucent, white; entire surface ornamented with fine, closely spaced spiral threads which are cut by equally fine but more widely spaced incised axial lines, toward the base the axial lines become fainter and the spiral cords broader; apex obliquely truncated, deeply, narrowly pitted, with both the axial and spiral sculpture entering the pit; aperture as long as the shell; outer lip rising from the edge of the pit with a rounded notch or sulcus partly reflected over it, above which the lip extends for a short distance before rounding sharply to form a narrow aperture along the body of the shell; columella curved, forming a broadening of the aperture, the edge broadly reflected over the umbilical region without a visible fold, the lower end extended downward to join the outer lip in a canallike projection. Dimensions: length, 9.8 mm.; maximum diameter, 3.6 mm.

The outer lip in the unique type is imperfect but the general characters of the shell seem to be quite different from any species described from the west coast. It differs from Atys chimera Baker & Hanna in the more uniform, closely spaced, raised sculpture, lack of columellar fold, and in a canal-like basal projection of the aperture. In shape the new species is more like Cylichna fantasma Baker & Hanna which species, however, lacks the apical notch or sulcus.
