Ranellidae

The Tritons are principally equatorial in their geographical distribution, and belong more especially to the Asiatic fauna. Those with the siphonal canal very much produced are obtained from deep water. The cancellated forms are from sand, in deep water; and those covered with an epidermis are chiefly from sandy mud, in from six to thirty fathoms.^[2]

According to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005, the family Ranellidae consisted of two subfamilies:

• Ranellinae Gray, 1854 - synonyms: Agrobuccininae Kilias, 1973; Simpulidae Dautzenberg, 1900; Gyrineinae Higo & Goto, 1993 (n.a.)
• Cymatiinae Iredale, 1913 (1854) - synonyms: Tritoniidae H. Adams & A. Adams, 1853 (inv.); Neptunellinae Gray, 1854; Lampusiidae Newton, 1891; Lotoriidae Harris, 1897; Septidae Dall & Simpson, 1901; Aquillidae Pilsbry, 1904; Nyctilochidae Dall, 1912; Charoniinae Powell, 1933

The Cymatiinae now form a separate family: Cymatiidae.

The family Ranellidae contains the following genera:^[1]
