costa. Umbilicus about a tliird of the width of the shell, deep, 

 conical, showing every revolution and almost all the embryonic 

 whorl, sculptured within similar to the spire. Aperture slightly 

 oblique, ovate, lunate ; peristome sharp, straight, except at the 

 columellar margin, where it is a little reflexed, viewed from above 

 the peristome describes a wide convex, then a sharper concave 

 curve on approaching the insertion. Callus on body whorl slightly 

 projecting past an imaginary straight line drawn from insertion to 

 insertion of the peristome, thin, transparent, just burying the 

 costse overtaken by it. Diam. maj. 4^, min. 4, alt. 2|mm.
