PUPILLA, AFRICA. 205 



tween the two lips, and that the pillar lip is broadly expanded 

 at its commencement. The type having been smashed, and an 

 imperfect photograph alone preserved, we cannot vouch for 

 the correctness of our figure" (Hanley & Theobald). This 

 figure is copied, as no specimens are available. 



29. PUPILLA ( 1) DIOPSIS (Benson). PI. 22, fig. 18. 



Shell perforate, oblong-ovate, obliquely striatulate, with a 

 few remote, slightly elevated striae, whitish under a corneous 

 epidermis. Spire oblong, conoid towards the rather obtuse 

 apex, the suture a little impressed. Five slightly convex 

 whorls, the last slightly ascending. Aperture oblong-ovate, 

 angular above, two-toothed: a narrow, obliquely entering, 

 median parietal lamella and an oblique, deeply-placed colu- 

 mellar tooth above. Peristome thin, the right margin simply 

 straight, columellar margin expanded. Length 2, diam. 1 mm. 

 (Benson).

A single specimen in a worn state was sent by Mr. W. Theo- 

 bald for examination (Bens.). 



1 ' We have figured the unique original, which does not well 

 display the remote columellar tooth ascribed to it ; the name, 

 says Benson, was a misprint for diploos" (Hanley & Theo- 

 bald). 



Gude, who followed Pfeiffer in placing this species in 

 Pupilla, adds nothing to the original account. Whether the 

 species is a Pupisoma, Ncsopupa or some other genus can 

 hardly be guessed from the description and figure. It does 

 not seem to be a Pupilla.
