Shell small, elongate, light pink, faintly dotted with brown. Whorls about 12, slightly convex, nodulously costate, spirally lirate, exhibiting at distant intervals paler thickish varices. Costae about 15 on the upper whorls, crossed by two principal transverse lirae, which are nodulous upon the ribs, giving the whorls a biangulate appearance at the sides. In addition to these two there are several (about seven) finer lira;, but which scarcely form nodules upon the costae. The body-whorl has the usual varix on the left side well developed, swollen. The aperture is round-ovate, acuminate above and prolonged anteriorly into an oblique, short, recurved canal. Columella arcuate, coated with a rosy callus, covering an elongate transverse tubercle above. Labrum thickened by a small external varix. Length 15 mm., diam. 4,5 mm
