This form consists of a fragmentary cast, which was determined, 

 after careful comparison with specimens in the British Museum. 

 It has the two last whorls, the basal one being without perforation 

 and showing a subrotund aperture ; the whorls are convex and 

 separated by a deep suture, the last showing an obscure carination 

 at the base.

 an acute elevated apex composed of angulated whorls with bicari- 

 nated margins ; surface ornamented with quincuncially-arranged 

 granulations and a series of radial costse ; aperture rhomboidal ; 

 periphery sharply keeled ; base with a wide umbilicus. Two 

 specimens only were found at Okeford Fitzpaine, and, although 

 not well preserved, retain sufficient characters for determination.
