The columella lias the peculiar twist of conic-a, but our shell 

 is smoother, more shining, the spire more tapering, and the 

 whorls much more depressed'' (Garrett).

The figure is from Kuester. Dohrn has suggested that the 

 species belongs to the Auriculacea. It is not likely that it in- 

 habits both of the islands mentioned above.

Shell oblong-conic, thin, striatulate, pellucid, glossy, 

 brownish-corneous. Spire conic, acute, whorls 6, convex, the 

 last subglobose, about one-third the total length. Aperture 

 ear-shaped, contracted by a compressed, entering parietal la- 

 mella and a twisted, subtruncate columellar callus. Length 

 3.5, diarn. 2 mm.; aperture 1.25 mm. long (Pfr.).

 out the group, but not plentiful. They were found adhering

 caying leaves (Garrett). Cook's or Hervey Is.: Aitutaka,
