The nomenclature of the gênera and subgenera of the family Cardiidae is still very 

 confused. Dall's scheme in the works cited above, appears to me to be rational, and I hâve 

 followed it with certain modifications in préférence to Stewart's more récent work. 



The génotype of Carditmi is Cardittni costatum Linn. designated by Children. The sub- 

 genus Cardium s. s., is not represented in the "Siboga" collection, but there are représentatives 

 of the subgenera Trachycardium Môrch ^) — type Cardùun [Trachycardmni) isocardia Linn., 

 Rijigicardittm P. Fischer ^) — type Cardium {^Ringicardiuni) r ingens Gmelin, Fraguni Rôding ^) — 

 type Cardium [Fraguni] ttnedo Linn., Pratuluni Iredale *) — type Cardium [Prahihim) thetidis 

 Hedley, Ctenocardia H. & A. Adams ^) type Cardium {Ctenocardta) hystrix Reeve = C. (C) 

 symbolicuni Iredale, Laevicardium Swainson ®) — t\pe Cardium [Laevicarditim] norvegicum
