Hah. Cope's Folly, Maritzburg (//. BiD'nup, Esq.). 



A neat, tlelicate, and chaste species, albeit of moderate 

 dimensions. It is white, with an ochraceous tinge, cylin- 

 drical, obtuse at the apex, six-whorled, tlie whorls being very 

 compressed at the sutures, so much so as almost to appear 

 channelled ; the aperture is ovate ; peristome shining white 

 and reflexed, furnished with a parietal plait of conspicuous 

 size and projection, also a columellar plait, internal and 

 nipple-shaped. Besides this there are four teeth, two labial, 

 the lower being the larger, one at the base, and one colu- 

 mellar. 



One specimen.

Very small for the genus, but of beautifully shining and 

 transparent texture, with the whorls quite smooth and the 

 mouth with a complicated arrangement of teeth and plaits, 

 two of each — the parietal or sutural plait being thin, sharp, 

 and prominent, the labial tooth conspicuous and large, the 

 basal smaller ; the columellar plait very distinct and wholly 

 internal. 



Two specimens.
