Pilsbry did not justify his action. Later, he (Pils-
bry, 1908a: 309) treated Cionella Jeffreys,
1830, as a synonym of Cochlicopa and Co-
chlicopidae and Cionellidae as synonyms of
Ferussaciidae. Although Cionellidae is still
occasionally used, especially in North America,
Cochlicopidae is in prevailing usage and
is conserved under Art. 40.2, with the precedence
of Cionellidae. -inae, Watson (1920:
