BOTHRIOPUPA. 231 



The surface is very closely pitted, or in some specimens the 

 pits are confluent, so that it appears covered with a very 

 irregular granulation. The aperture is somewhat oblique, 

 peristome expanded, not thickened, whitish. The parietal 

 lamella is very high and rather long, curved. Columellar 

 lamella small and placed far within. The lower palatal plica 

 is tuberculiform and nearly basal in position. There are no 

 other teeth. 



Length 1.8, diarn. above aperture 1.25 mm. 



Length 1.7, diam. above aperture 1.1 mm.

This is one of the rarest Pupas; yet, from the records at 

 hand, it will probably be found throughout the peripheral 

 keys. The absence of an upper palatal plica, the short lower- 

 palatal, and the smaller columellar lamella distinguish it 

 from B. tenuidens throughout the series of each examined. 

 The pitting was very poorly represented in Gould's figure.

"Shell perforate, globose-conic, thin, striatulate, diaph- 

 anous, little shining, brown; spire conoid, the apex obtuse. 

 Whorls 4%, convex, the last one-third the length, rotund at 

 base. Aperture a little oblique, semicircular, toothless; peri- 

 stome simple, a little expanded, the columellar margin some- 

 what dilated, broad. Length 1%, diam. 1 mm. In perfect 

 specimens there are two plicae, one parietal, the other trans- 

 verse, on the columella" (Pfr.).
