''Bacchites'' is an extinct ammonoid cephalopod genus belonging to the ceratitid family, Juvavitidae. ''Bacchites'', named by Smith, 1927, has a subspherical shell with the closed umbilicus, the surface of which is almost smooth except for faint transverse ribs, vestigial constrictions, and a faint threadlike keel. The suture is ammonitic. This genus, previously included in the Haloritidae, was removed to the Jovavitidae, established by Tozer, 1971, which is based on the genus ''Jovites''. Both families are included in the Tropicaceae. ''Bacchites'' has been found in upper Middle Triassic (Carnian) age sediments in the Alps, Timor, and California. ==''References''== *Arkel ''et al.'', Mesozoic Ammonoidea; Treatise on Invertebrate Paleontology, Part L, Ammonoidea.
