: Small, turbiniform (L/D=1.00–1.16); teleoconch of up to 3.5 whorls; sculpture strongly cancellate; first whorl initially sculptured only by axial pliculae, relatively widely spaced at first, but becoming more close-set toward end of first half whorl; 3 spiral cords develop during first whorl, one at mid-whorl, one between this and adapical suture and the third level with abapical suture; that at mid-whorl strongest and becoming peripheral cord of later whorls; cords become progressively stronger with growth, a fourth appearing below adapical suture during third whorl; axial pliculae more widely and regularly spaced from second whorl onward; pliculae cross cords producing angular nodules at intersections; in final quarter of last adult whorl an additional intermediary spiral cord arises between each of the primary cords (

); for the most part, intervals between cords noticeably wider than cords themselves; last adult whorl with 25–30 pliculae; pliculae narrower than cords; interstices obliquely quadrate. Base with 4 somewhat more close-set spiral cords, including that level with suture, a weaker fifth one sometimes evident, closely juxtaposed to the fourth and spiralling into umbilicus; umbilicus remaining patent at maturity, its width variable between individuals, often somewhat obscured by reflected upper part of columella lip. Peristome markedly oblique, almost tangential; aperture subcircular; columella concave, lacking dentition; outer lip notched at ends of spiral cords, somewhat thickened internally, but lacking both internal teeth and in-running ridges; interior of aperture nacreous, angled beneath external cords.
