40G Mr. H. C. Buniup on South- African 



Typograi)!iical errors in the original vender a new descrip- 

 tion necessary. 



Shell minute, rimate, subcylindrical, elliptical, thin^ trans- 

 lucent, shining, very pale brown; spire elongate-turbinate, 

 with greatest width at the fourth whorl ; sutures rather 

 deeply impressed, apex very obtuse ; whorls 5^, very convex, 

 closely transversely striate, excepting the first 1^, which are 

 smootii, tiie last compressed round the umbilical region ; 

 aperture nearly erect, rounded, nearly ^ the height of the 

 shell. Peristome slightly thickened and reflexed, more so at 

 the columellar margin, scarcely paler than the rest of the 

 shell, with labrum slightly straightened about the middle and 

 much receding towards the base ; columella arcuate. The 

 only tooth, conspicuous, white, rounded, and remote, is 

 situate inside, about midway between the last suture and the 

 base and about half a turn from the labrum. 



Height 1-47, width 0-79 [fig. 5 (Survey)].

Bab. Pretoria {Farquhar 4' Fonsonby). Major Connolly 

 lias since supplied me with many specimens, quite agreeing 

 with the type, from the same locality. 



The following are the dimensions of the largest and 

 smallest adult specimens measured : — 



Largest : height 1-51, width 0-80. 



Smallest: „ 1-32, „ 0-75. 



This is the smallest of the South-African group examined 

 by me, and is of a paler colour than most. As compared 

 with P. perple.va, which seems to be its nearest ally, it is 

 smaller, smoother, paler, and less cylindrical, is only rimate 

 instead of umbilicate, has the peristome less reflexed, and is 

 destitute of the ]X)stcoluraellar and parietal plaits. As com- 

 pared with dysorata, of which intradentata appears in the 

 Survey as a variety, it is smaller, more slender, paler, less 

 cylindrical, more loosely coiled, with more ventricose whorls 

 and deeper sutures, and is rimate instead of umbilicate ; the 

 aperture is smaller and rounder, receding more at the base, 

 and is furnished with a tooth in the gullet, not found in 

 dysorata. 



I am indebted to Mr. Ponsonby for making a careful 

 comparison between Mr. Sykes^s type of dysorata and the 

 type of intradentata in the British Museum, when he was 

 able to confirm most of the details given above.
