Sydney, low water, under stones (Mr. Strange). A black-brown species, with three rows of regular, equal sized granules on each whorl. Translation of the Latin text. Pyramidal shell, dark brown; flat whorls with three rows of equal sized dense granules, whorls with impressed sutures, convex base. Diagnosis. Lectotype 6.7 mm high. Shell conical with rather flat whorls. Teleoconch of ten whorls, with three strong spiral cords forming nodules at the intersection with the orthocline axial ribs.
