Not illustrated. 1908 edition. Excerpt: ...when highly magnified; spire low, conoidal, apex rather prominent, suture well impressed.; whorls 6, convex, increasing slowly, the last scarcely broader, bluntly subangulate at periphery, flatly convex below; aperture oblique, broadly lunate; peristome thin, basal margin slightly arcuate, columellar curved, oblique, not reflected over the umbilicus, but carried forward for a short distance. Major diam. 12, min. 11, height 5j mm. Hab. Ceylon and Southern India; Trichinopoly, Kolamalai Hills, Arcot (W. T. B.); Myhendra, Travancore (Beddome).
