crossed by impressed spiral lines, smootlier and polished beneath ; 

 spire conoidal, apex obtuse, suture impressed ; whorls 5, convex, 

 the last descending a little towards the mouth, bluntly angulate 

 at the periphery, cotivex beneath, compressed around the per- 

 t'oratio)! ; aperture large, diagonal, roundly lunate ; peristome 

 thin, arcuate above near last whorl, columellar margin oblique, 

 expanded, more broadly above, and thickened, partly covering the 

 perforation.

This is a peculiar form to be recognized by its large diagonal

Shell subobtectly perforate, depressedly turbinate, white, with 

 a fulvous to dull chestnut epidermis, striated, the striation broken 

 and decussated by impressed lines, which are less distinct below ; 

 spire conoid, apex acute, suture impressed ; whorls 7, slowly 

 increasing, convex above, the last not descending, angulate (vary- 

 ing from subangulate, or even rounded, to carinate) at the peri- 

 phery, more convex below than above; aperture oblique, angulately 

 lunate ; peristome straight, slightly obtuse in adults, columellar 

 margin briefly reflected, partly covering the perforation. 



Major diam. 38, min. 80, axis 19 mm. 



[Aiiimal. iSole of foot not divided, in spirit folded on the central 

 line. There is a minute rudiment of a I'ight shell-lobe, the left 

 dorsal is in two parts, the anterior very close to the posterior. The 

 male organ has a large loop formed by a strong connecting muscle 

 a short distance above the generative aperture. The sperraatheca 

 is short and globose. Jaw has a very slight central projection 

 (iig. 80 B, p. 52). Kadula (fig. 80 B) formula:
