Systematic changes since creation of ‘Bivalve life habit dataset’
B1) Species previously referred to Amusium Röding, 1798
in the regional literature for both fossil and Recent taxa are currently
under revision (Waller, 1991). These species are here treated under three
genus-level groups, Amusium (sensu stricto), “Euvola” and
Euvola (“Oppenheimopecten”) (T. Smith pers. comm.
B2) Neotropical Flabellipecten require revision and are
currently referred to as “Flabellipecten” (T. Smith pers. comm.
B3) Following Olsson (1961), Leptopecten is now divided
into two subgenera, Leptopecten ( L.) and L. (Pacipecten).
B4) Lyropecten (Nodipecten) is now elevated to
genus Nodipecten following the systematics of J. Smith (1991).
B5) Lucina (Lepilucina) has been elevated in rank
to genus Lepilucina (J. D. Taylor pers. comm. 2001).
B6) Lucina (Lucinisca) has been elevated in rank
to genus Lucinisca.
B7) The misspelling Hastasia (of Olsson, 1961) has been
corrected to Hatasia Gray.
B8) Specimens assigned to Norbicula Iredale, 1930 have
been re-identified as Varicorbula Grant & Gale, 1931 (L. Anderson
Systematic changes since creation of ‘Gastropod diet dataset’
G1) Puncturella (Esmeria) Olsson, 1964 has been elevated
to generic level and replaced by its senior synonym Altrix Palmer,
1942, following McLean & Geiger, 1998.
G2) Cingula (Microdochus) Rehder, 1943 is now
synonymized with the genus Elachisina Dall, 1918 and placed in the
Rissoidea: Elachisinidae (see Ponder 1985).
G3) Theodoxus (Vittoclithon) H. B. Baker, 1923
is now synonymized under the genus Vitta Mörch, 1852.
G4) Siliquaria Bruguière, 1789 has been replaced
by its objective senior synonym Tenagodus Guettard, 1770 (Bieler,
G5) Specimens identified as Tectarius Valenciennes, 1832
have now been subsumed within Cenchritis von Martens, 1900.
G6) Mitra (Fusimitra) Conrad, 1865 is now recognized
as a distinct mitrid genus.
G7) Hindsia A. Adams, 1851 has been replaced by its objective
senior synonym Nassaria (Nassaria) Link, 1807 (Cernohorsky,
G8) Crepidula is now treated under 3 subgenera C.
(C.), C. (Bostrycapulus) Olssen & Harbison, 1953
and C. (Ianacus) Mörch, 1852.
G9) Bezanconia probably belongs to the Cerithiidae and
has been placed there.
G10) Following Warén's (1983) suggestion, Balcis
Leach, 1847 has been synoymized with Melanella Bowditch, 1822.
