I'his species lias been ascribed both to Vertagus (= Clava) and Ceritkium. Dunker 

 himself and Tryon, describe it as I 'er/agus, Kobei.t and Watson (Challenger-Gastropoda) as 

 Cerithium. 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) 

 ■ rhe Vertagus Pfefferi of Dunker is not a Vertagus or Clava, but a true Cerithium". The 

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

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

 the cohunellar side, which is very strong in young and broken specimens, if one looks however 

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

 at has been stated by DUNKER, bnt also considerably in size.
