form angular lamella below the insertion of the outer lip and 

 separated from it by a groove. 



Length 4.55, diam. above aperture 1.4, to edge of outer lip 

 1.6 mm. ; length of aperture 1.35 mm. ; 6y 2 whorls. 



South Africa: probably from the neighborhood of Port 

 Elizabeth ; collected by Crawford. Bryant Walker coll. 



The very slender contour of this form apparently indicates 

 specific distinction ; otherwise it is closely related to the wide- 

 spread P. coenopictus. 



Pupoides minusculus (Mousson). Vol. XXVI, p. 139. 



E. Degner has proposed Leucochiloides minusculus var. 

 major (Beitr. zur Kenntnis Land- und Siisswasserfauna 

 Deutsch Siidwestafrikas, Mollusca, 1922, p. 31) for specimens 

 with only 5 flatter whorls, regularly increasing in height, the 

 suture shallower, last whorl § to ^ of the length. He gives 

 localities: Tsumeb, Grootfontein, Otavifontain, Okaputa, Oka- 

 hand j a, Karibib, Osona. Whether they are referable to cala- 

 haricus or minusculus appears doubtful, as they form an in- 

 termediate phase. 



P. calaharicus (Bttg.) is reported from Kuibis (p. 33). 



Glyptopupoides new subgenus. 



The shell is PwpowZes-shaped, of few (about 4^) whorls, 

 the embryonic iy 2 minutely, densely pitted, the rest distantly 

 ribbed and spirally striate. Peristome expanded, but little 

 thickened ; no angular tubercle or other teeth. Type Pupoides 

 hedleyi. 



Pupoides hedleyi new species. PI. 31, fig. 15. 



The shell is oblong with convexly tapering spire and obtuse 

 summit ; snuff-brown throughout ; but slightly shining. First 

 iy 2 whorls are microscopically, very densely pitted, the rest 

 sculptured with narrow, rather widely-spaced, retractive rib- 

 lets, the intervals minutely and closely striate spirally, the 

 striae varying from distinct (as in the type) to quite weak in 

 some other specimens. The whorls are rather convex, especi- 

 ally the penult. The aperture is ovate, somewhat oblique,
