This species has been ascribed both to Vertagus (= Clava) and Cerithmm. Dunker 

 himself and Tryon, describe it as Vertagus, Kobelt and Watson (Challenger-Gastropoda) as 

 Cerithmm. Pilsbry, who in his "Catalogue of the marine Mollusks of Japan, 1895, p. 56, 

 enumerates it as Clava Pfefferi, says in 1901 (Proc. Acad. Nat. Sciences, Philadelphia, p. 393) 

 "The Vertagus Pfefferi of Dunker is not a Vertagus or Clava, but a true Cerithitun'. The 

 "Siboga" -specimens agree in every particular with the original figure and description of Dunker, 

 but if one looks into the aperture in an oblique direction, one sees a more or less distinct fold on 

 the columellar side, which is very strong in young and broken specim.ens, if one looks however 

 at the adult shell en face, the fold is not visible at all. The species yaries not only in colour, 

 at has been stated by Dunker, but also considerably in size.

 of Kobelt, in keeping the two species separated, else the name of Bruguiere should have
