Description. "Shell minute, the extreme length of the only 

 specimen known being only about one-sixth of an inch. Apical 

 angle 38 or 40, giving a sharply conical spire; volutions five in 

 number, very slightly scaliform, with channeled sutures, but with 

 the surface of the volution flattened in the direction of the spire ; 

 apex apparently rounded; body volution subangular at the line 

 of contact with the lip; aperture acute-ovate, sharp at the upper 

 margin, and possibly pointed below (the specimen is imperfect 

 at the base) ; columella slender, rounded, slightly prolonged; 

 marked by a proportionally very strong 1 , tooth-like ridge just 

 below the swell of the volution ; outer lip of the aperture sharp ; 

 axis imperf orate; surface smooth, but not polished on the speci- 

 men, though the dullness present may be the effect of solution. " 

 (Whitfield.) 



Remarks. This species is known from a single specimen less 

 than 5 mm. in height, which is possibly an immature shell.
