Fusus is a genus of small to large sea snails, marine gastropod molluscs in the family Fasciolariidae, the spindle snails and tulip snails.

Fusus as a name for a genus of gastropods has confusingly been used three times. These names are, in whatever taxonomical sense, now invalid. This page is kept for historical reasons.

The name of the genus Fusus Bruguière, 1789 is invalid as it is a junior homonym of Fusus Helbling, 1779. (Placed by the ICZN on the Official Index by Opinion 1765, 1994, Bulletin of Zoological Nomenclature, 51(2): 159). The accepted name is Fusinus Rafinesque, 1815 ^[2]

The genus Fusus Helbling, 1779, has also been placed on the Official Index by Opinion 1765 (1994, Bulletin of Zoological Nomenclature 51(2): 159-161), i.e. it cannot be used as a valid name. The type species of Fusus Helbling is Murex intertextus Helbling, 1779 (= Fusus intertextus Helbling, 1779), and it belongs in the family Colubrariidae.^[2]

Fusus Helbling, 1779 (Mollusca, Gastropoda) has been suppressed, and Fusinus Rafinesque, 1815 and Colubraria Schumacher, 1817 are conserved. ICZN 1993. Opinion 1765. Bulletin of Zoological Nomenclature, 51(2): 159-161 CZN 1993. Opinion 1765. Bulletin of Zoological Nomenclature, 51(2): 159-161

The genus Fusus Röding, 1798 (type species = Fusus cynara Röding, 1798 = Turbinella angulata (Lightfoot, 1786) ) is a junior homonym of Fusus Helbling, 1779. It has also been placed on the Official Index of the ICZN by Opinion 1765 and is an invalid name.
