PUPILLA, AFRICA. 213 



A small, insignificant shell, with one internal sutural or 

 parietal tooth. Two specimens (M. & P.). 



Pupa charybdica. PI. 16, fig. 11. Shell compact, rather 

 thick, cylindriform, brown, apex obtuse; whorls 7, straight, 

 longitudinally obscurely and obliquely delicately striate; 

 aperture rounded ; peristome thickened, pale, reflected, pro- 

 vided within with three mamillar teeth, one parietal, another 

 columellar, the third basal. Length 3, diam. 1.15 mm. Coer- 

 ney, near Port Elizabeth. 



A cylindrical dark brown shell, not shining, stouter in sub- 

 stance than most of its congeners; whorls seven, straight, 

 longitudinally, obscurely and obliquely finely striate; aper- 

 ture round; peristome incrassate, reflexed, furnished with 

 three internal teeth basal, columellar, and sutural. Three 

 specimens (M. & P.). 



Pupa frustillmn. PI. 16, fig. 13. Shell glossy, cylindric, 

 bright brown ; whorls 7, straight, obliquely very finely striate ; 

 aperture ovate ; peristome pale brown, provided within with 

 three teeth : one parietal, another basal, the third columellar. 

 Length 3.5, width 1.25 mm. Port Elizabeth. 



Near P. fontana Krauss, but more cylindrical than that 

 species, and differing besides in the tooth-processes (M. & P.}. 



Pupa elizabethensis. PL 16, fig. 5, topotype. Shell minute, 

 openly rimate, glossy, shining white, shortly cylindric ; whorls 

 7, lightly subventricose, most minutely striatulate under a 

 lens ; aperture rounded, provided with two entering folds, one 

 parietal, the other columellar, deeply entering; peristome a 

 little reflected. Length 3, width 1.2 mm. Port Elizabeth 

 (Miss Glanville) (M. &P.}. 



Pupa amphodon. PI. 16, fig. 12. A small cylindrical 

 species of the fontana group. In many ways it approaches 

 P. frustUlum M. & P., but differs entirely in the labial tooth- 

 processes. It is subrirnate, with seven whorls, two of them 

 being apical, the apex itself extremely obtuse ; whorls slightly 

 ventricose and indistinctly longitudinally striate; mouth 

 lunar, peristome round, furnished with five processes, which 

 well-nigh close the orifice. The parietal tooth is the most con- 

 spicuous of these and is straight and produced, the labial is 

 broadly triangular, the two basal are respectively doubly 

 mamillar and broadly triangular, and the remaining colu- 

 mellar tooth is smaller, rounded, and mamillar. The peri- 

 stome is incrassate, reflexed, and broader towards the colu- 

 mellar region (M. & P.).
