 aperture angularly and widely ovate, oblique ; peristome double,

 rounded on the periphery of the whorl, then descending, with 

 indistinct crenulation up to the subvertical columellar margin, 

 which is thickened below ; operculum black, placed too far in to

Orujinal description'. — "Shell somewhat depressedly turbinate 

 and umbilicated ; sculpture : fine and rather close costulation 

 on the upper whorls, much stronger next the sutural tube, and 

 near the base of this peculiarly distant costse very strong ; colour 

 white; spire conoid ; suture impressed, sutural tube long ; whorls 

 4, the last swollen, next sutural tube sharply constricted, then 

 suddenly expanding into a rounded ridge crossing the whorl
