upper, which descends inwardly, both being visible as whitish 

 lines externally (fig. 5). Topotypes measure: 



Length 9.4, diam. penult whorl 3 mm. ; 9y 3 whorls. 



Length 8, diam. penult whorl 3 mm. ; 8y 2 whorls. 



Mr. Burnup's illustrations of specimens from Hermanus, 

 Caledon Division, east of False Bay, show the "neck" is 

 shorter than in shells seen from the Peninsula. Mr. Burnup 

 writes : 



"Since the peristome is not at all thickened at the edge, 

 but, on the contrary, is remarkably thin and brittle, the lips 

 are invariably more or less chipped. One of the most con- 

 spicuous differences between the present species and P. craw- 

 fordiana M. & P. is the absence from the latter of the trumpet- 

 like extension of the peristome observable in the former." 



The dimensions of two specimens figured by him are as 

 follows : 



Height 7.87, width 3.26 mm. 



Height 7.87, width 3.67 mm. 



"The shells of this species may be either white or horn 

 color, and the position of the seventh peristomatal process, 

 the denticle between the inferior parietal and the columellar 

 plait is very variable; it is sometimes seen on the parietal 

 wall, sometimes on the columella, and sometimes in the angle 

 between ' ' ( Burnup ) . 



Pupa soluta Pf r. - - Shell deeply rimate, long-conic, thin, 

 very lightly striate, pellucid, brown-corneous. Spire ovate- 

 conic, the vertex rather acute. Whorls 9, a little convex, the 

 last free in front, produced horizontally, compressed at the 

 base. Aperture reaching beyond the axis at base, truncate- 

 oval, nearly closed by 6 long lamellae : one parietal and the 

 upper palatal stronger and reaching the margin, the second 

 palatal, one basal and two columellar lamellte more deeply 

 placed ; peristome continuous, thin, shortly expanded, the 

 upper margin free and a little straightened. Length 8, diam. 

 of penult, whorl 3 mm. ; aperture 2% mm. long, 2 wide (Pfr.).
