Hob. Noord Hock {Lancjley) and Monk's Kloof. 



An extremely beautiful small species, of horny-wliite 

 colour, bluntly cylindrical ; mouth ovate-oblong, slightly 

 produced, the lip shining white, thick, much reflexed, with 

 four plaits ; of these the parietal and labial are very large, 

 shining white, the basal smaller and simple, the internal tooth 

 below the columellar margin being sliining white and 

 roundly nipple-shaped. This species seems widely distri- 

 buted and variable ; we have been able to examine a con- 

 siderable number of individuals.

Hah. Griqualand East {E. R. Si/kes). 



A smaller species even than the last, to which it possesses 

 many points of similarity, but the nearly closed, very nar- 

 rowly auricular mouth, with shining white and unusually 

 thickened subreflexed lip, and prominent plica3 amply dis- 

 tinguish it.
