Melongenidae

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

Taxonomy

For a while prior to 2004, the genera Busycon and Busycotypus were placed in the Melongenidae. Then, in 2004, based on their digestive [system of gastropods|digestive system]s and on cladistic analysis by Kosyan & Kantor, 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 - synonyms: Cassidulidae Gray, 1854 ; Galeodidae Thiele, 1925 ; Volemidae Winckworth, 1945; Heligmotomidae Adegoke, 1977
Subfamily Echinofulgurinae Petuch, 1994
