Description, "Shell rather above the usual size, short conical, 

 and rather obese in general form, oblique as seen from the back ; 

 composed of two and a half or three volutions, which increase 

 somewhat rapidly in size with increased growth ; apical angle 

 about 70 ; volutions ventricose, obliquely flattened on the upper 

 side and obtusely round-pointed below, with a quite distinct 

 angulation at the upper third, or just above the upper third of the 

 length, as seen on the last one, and a less distinct one below the 

 middle, dividing the body volution into three sections, of which 

 the middle one is rather broader than the others and imperceptibly 

 flattened ; above the body volution the whorls are marked by about 

 eight vertical folds, or angulations representing folds, which do 

 not extend to the suture line on the cast, the only condition in 

 which it has been observed; aperture elongate ovate, largest 

 below ; columellar cavity in the cast of medium size, marked at 

 the base by a distinct groove, indicating the presence of a tooth- 

 like ridge on the shell, showing the generic position of the species ; 

 the surface has also been marked by spiral lines or ridges, 15 or 

 more in number, on the last whorl near the lip, very perceptible 

 on the surface between the whorls in the cast." (Whitfield.)
