The Melongenidae, the crown conchs and their relatives, are a taxonomic family of large to very large marine gastropods in the superfamily Buccinoidea.^[1]

Taxonomy

For a while prior to 2004, the genera Busycon and Busycotypus were placed in the Melongenidae.^[2] Then, in 2004, based on their digestive systems and on cladistic analysis by Kosyan & Kantor (2004),^[2] these two genera were moved to the family Busyconidae within the superfamily Buccinoidea.

According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005), the Melongenidae consists of two subfamilies:

Subfamily Melongeninae Gill, 1871 (1854) - synonyms: Cassidulidae Gray, 1854 (inv.); Galeodidae Thiele, 1925 (inv.); Volemidae Winckworth, 1945; Heligmotomidae Adegoke, 1977
Subfamily Echinofulgurinae Petuch, 1994

Genera in the family Melongenidae include:^[3]
