Shell minute, depressed globose, perforate, corneous, thin, pellucid, 

 polished. The only sculpture on the post-nuclear whorls consists of 

 microscopic faint spiral lines, more distinct on the base ; growth- 

 lines sometimes rib-striate. Colour corneous, at irregular intervals 

 there are radiate white lines on the last two whorls, produced by the 

 narrow callosity left of former peristomes. Spire conoidal, its height 

 equal to that of the aperture ; outlines lightly convex. Protoconch 

 flatly rounded, smooth. Whorls 5, slowly and regularly increasing, 

 convex ; periphery subangled, base flatly rounded. Suture impressed, 

 faintly margined. Aperture oblique, lunate. Peristome simple, straight, 

 with a conspicuous inner white callus. Outer Up descending rapidly 

 and but little arched. Columella short, subvertical, arcuate. Inner
