Palaeotrochidae Knight, 1956 [8 March]

Type genus: \Palaeotrochus Hall, 1879
Remarks; No diagnosis, but made available
under Art. 13.2.1 by usage as a valid name
before 2000. First diagnosed and -oidea [as
-acea]. Knight, Batten & Yochelson (in
Moore, 1960: 302). Gurich (1896: 309) had
already used the name Palaeotrochidae to
group the "ancient trochids", but did not implicitly
or explicitly include Palaeotrochus,
and the name appears to have been descrip-
tive.

Paludestrinidae Newton, 1891 [22 August]
Reference; Systematic list of the F. E. Edwards
collection of British Oligocène and Eocene
Mollusca in the British Museum {Natural History):
226
Type genus: Paludestrina d'Orbigny, 1840
Remarks; There is an earliest and hitherto
overlooked type species designation for
Paludestrina, by subsequent designation by
Nevill (1885; 46); Paludina nigra d'Orbigny
1 840, which is a species of Eatoniella. This
would render Paludestrinidae a senior synonym
of Eatoniellidae Ponder, 1965. The
case will be presented under Art. 41 to the
ICZN by D. Kadolsky (pers. comm. pers.)
to conserve the name Eatoniellidae.
Paludestrinidae was introduced as a substitute
name for Hydrobiidae, based on the
erroneous assumption that its type genus
Hydrobia Hartmann, 1821, was a junior
homonym of Hydrobius Leach, 1817 [Co-
leóptera], -inae, Preston (1915; 167).
