A small simple-moutlied species, of which the type only 

 occurred, unfortunately mLslaid soon after description, fifteen 

 years ago. No example has since come to hand. Seemingly 

 allied to P. pretoriensi's, M. & P.

" Shell very small, rimafce, snbcylindrical, elongate, thin, 

 translucent, sliining, pale brown ; spire slightly narrowing 

 upwards, the greatest width being at the fifth and sixth 

 whorls, sutures impressed. Apex obtuse ; whorls 7^, very 

 convex, closely lirate transversely, excepting the first 2^, 

 which are smooth, the last whorl compressed round the 

 umbilical region, and flattened near the middle of the labium ; 

 aperture straight, subangularly rounded, about ^ the height 

 of the shell, peristome reflexed, widely so at the columellar 

 margin, slightly thickened, pale, untoothed, with labium 

 somewhat incurved about the middle, columella straight. 



"Alt. 2-17, lat. 0-92 mm. (maj.). 

 „ 2-10, „ 0-88 „ (min.). 



" IJab. Pretoria, Transvaal (Collier, McBean,S,- Farquhar) ; 

 Heidelberg {Miss Livingston) ; Dukuduku Forest, Zululand 

 {Topjjin). 



" A slender cylindrical form which seems to be quite distinct 

 from all described sj)ecies, though seemingly comparable 

 with P. quantula, M. & P., which is less tapering upwards, 

 broader in comparison to its length, and fine in sculpture, 

 and also with P. pentheri, Stur., a more conical shell, with 

 smoother sculpture, the whorls particularly ventricose, and 

 shallower sutures." {11. C. B.) 



The original type (from Pretoria) is slightly smaller in 

 dimensions than those given above, and is not in very perfect 

 condition. 



Var. Uvingstoncc, nov., Burnup, MS. (PI. I. fig. 12.) 

 Shell very similar to the typical form, eight- whorled, 

 cylindrical, impressed at the sutures, somewhat coarsely
