Alt. 25-300 mm. 



Hab. West coast of Africa. 



Shell elongated, somewhat cylin- 

 drical but ventricose towards the middle, 

 reddish yellow, which becomes paler in full- 

 grown specimens, covered with a dark brown 

 epidermis which is entirely coated in 

 adults with the enamel-like glaze. The 

 spire and apex are almost entirely obliter- 

 ated in full-grown individuals, and the 

 reflected upper border of the body whorl 

 exposes a wide, somewhat excavated, snout- 

 like area, from which the species obtains 

 its name. The pillar has four plaits, the 

 last being comparatively small (Broderlip).
