178 TORNATELLINA. 



The columella has the peculiar twist of conica, but our shell 

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

 whorls much more depressed" (Garrett). 



35. T. TBOCHLEARIS 'Beck' Pfr. PL 35, fig. 9. 



Shell ventricose-fusiform, glossy, pellucid, pale corneous. 

 Whorls 6, flattened, the last shorter than the spire, tapering 

 basally. Aperture oblong; peristome simple, lamella of the 

 parietal wall of the aperture transverse, large, acute. Length 

 4, diam. 2 mm. (Pfr.).

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. 



36. T. PHILIPPII Pfeiffer. PI. 36, fig. 4. 



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, diam. 2 mm.; aperture 1.25 mm. long (Pfr.). 



Society Islands: Tahiti (Philippi, Jr.) ; distributed through- 

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

 to the under side of loose stones, beneath dead wood and de- 

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

 under decaying leaves in forests near the sea-shore. Austral 

 Is.: Rurutu. Marquesas Is.: Dominique Island, under dead 

 leaves (Garrett).
