 from topotypes received from Farquhar.

Shell rimate-umbilicate, ovate-conic, subcylindric, obliquely 

 striatulate, shining, translucid, olivaceous-corneous. Spire 

 conoid-cylindric, the suture impressed, apex obtuse. Whorls 

 6, convex, the last compressed around the umbilicus. Aper- 

 ture slightly oblique, angular-ovate; peristome a little re- 

 flected, whitish; columellar margin expanded, deep within, 

 parietal provided above with a whitish entering fold. Length 

 3%, diam. 2 mm. (Bens.).

The shell is perforate and shortly rimate. The base, while 

 somewhat compressed, is rounded, not pinched up as in tabu- 

 laris. The small angular lamella is enlarged at the anterior 

 end and has a slight tendency to be forked there; inward it 

 penetrates about a third of a whorl. The columellar lamella 

 is merely a low, blunt prominence. A Simonstown specimen 

 measures : length 3.2, diam. above aperture 1.6 mm., 6 whorls. 

 Melvill & Ponsonby give the measurements of a paratype as 

 3.1 x 1.76 mm., evidently measuring to the edge of outer lip. 



A young specimen from Karkloof, pi. 8, fig. 5, diam. 1.2 

 mm., has the usual strong columellar and angular lamella?, 

 and three delicate baso-palatal folds, not so strong as usual 

 in L. cylindracea but spaced about the same. Other equally 

 young ones show one of these folds or none, and there are
