Herein we try to clarify these cases by proposing available replacement names. For three taxa new replacement names are introduced: Nassarius fritzsteiningeri nov. nom., (pro Nassa dispar BOETT- GER 1902), N. signatodentis nov. nom. (pro Buccinum signatum “PARTSCH” HÖRNES 1852) and N. taurinospeciosus nov. nom. (pro Nassa speciosa BELLARDI 1882).

Wir versuchen diese Fälle zu klären und verfügbare Ersatznamen vorzuschlagen. Für drei Taxa werden neue Ersatznamen eingeführt: Nassarius fritzsteiningeri nov. nom., (pro Nassa dispar BOETTGER 1902), N. signatodentis nov. nom. (pro Buccinum signatum „PARTSCH“ HÖRNES 1852) und N. tauri- nospeciosus nov. nom. (pro Nassa speciosa BELLARDI 1882).
