•' Resembles Bidimus elongatidus, Pfr,, but may be distinguished 

 from it by the whoiLs being less convex and the columella straight 

 instead of incurved.'' (Tryon.) 



The type-specimen is ligured by Pilsbry, who states that it 

 differs from P. haughioni, Bens., to which it has been referred as 

 a synonym, by the nou-sinuous columella, which does not form 

 an angle with the parietal wall, by the narrower mouth, more 

 numerous whorls and slenderer shape. He further compares it 

 with tlie var. oxynter of Benson, which, while nearly as slender 

 as pealei, differs by having the columella at an angle with the 

 I)arietal wall.
