K), as broad as interspaces, opisthocline with a prosocline inflexion on sutural ramp; sixteen to 17 axial ribs on antepenultimate and penultimate whorl, 17–18 on last whorl. Adapical part of whorl surface sculptured on last two whorls by indistinct spiral lines; 7–8 spiral grooves, with a tendency to form rectangular granules where crossing axial ribs, on the rostrum. Aperture oblong-ovate, columella relatively straight with a moderately thick callus, its outer edge slightly raised; parietal region concave, parietal pad filling posterior angle of aperture, constricting anal sinus.
