ly placed Bulla Linnaeus, 1758, on the Offi-
cial List with Bulla ampulla Linnaeus, 1758,
as type species. Vesica has the same type
species (by subsequent designation by Gray,
1847b: 161), and Vesicidae is thus an ob-
jective synonym of Bullidae.

Type genus: Vitriplutonia CoW'mqe, 1893
Remarks: Replacement name for Plutoniinae,
based on the erroneous assumption that its
type genus Plutonia Morelet, 1864, was preoccupied
by Plutonia Hicks, 1871 [Thlobita].
Vitrinoplutoniinae is an incorrect subsequent
spelling by Thiele (1926 [in 1925-1926]: 143).
ViviPARiDAE Gray, 1847 [November] (1833)

Type genus: V/V/pams Mon tfort, 1810
Remarks: -inae. Gill (1871: 7); -oidea [as
-oideae], Hannibal (1912a: 192). When he
established Viviparidae, Gray listed Paludina
in synonymy of Viviparus, and Viviparidae is
implicitly a substitute name for Paludinidae,
earlier employed by Gray (e.g., 1840c: 152).
Under Art. 40.2, Viviparidae takes the precedence
of Paludinidae. Placed on the Official
List by Opinion 573 (1959: 118).
