240 FAUXULUS. 



Pupa pottebergensis Krauss, Kuester. PL 39, fig. 8. The 

 shell is coiled sinistrally, cylindric-ovate, very blunt-pointed, 

 somewhat narrowed below, very finely, obliquely striate, 

 rather shining, pale horn-yellow, thin-walled, almost trans- 

 parent ; neck sharpened keel-like ; umbilical opening very 

 small, round. The 7 whorls are low, but little convex, rather 

 oblique; the suture is simple, rather impressed. Aperture 

 rounded, hanging down rather sack-like, contracted by several 

 folds, of which two stand on the parietal wall, one on the 

 colmnella and two deep in the palate. Of the folds of the 

 parietal wall, one is larger and begins at the outer edge, the 

 other being deep in the throat. Peristome disjoined, sharp- 

 edged, hardly reflected. Alt. 2y 2 , width 1% lines. On plants 

 on Potteberg Mountain, Zwellendam District, in the Cape 

 Colony, discovered and sent by Dr. Krauss in Stuttgart 

 (Kuester).
