Type genus: Jacosta Gray, 1821
Remarks: Introduced as a replacement name
for Helicellidae Ihering because Pilsbry treated
Jacosta as a senior synonym of Helicella
Férussac, 1821 . Jacosta has been placed on
the Official Index by Opinion 431 (1956: 349,
351 ), hence rendering Jacostidae invalid.

Janthinidae Lamarck, 1822
Reference: Histoire naturelle des animaux
sans vertèbres, 6(2): 204
Type genus: Janthina Röding, 1798
Remarks: The name Janthinidae is sometimes
attributed to Lamarck (1812:117), who keyed
"Janthine [Genre unique de sa famille]" [= only
genus of its family]; we do not regard this as
a valid establishment of the name under the
Code. Original spelling (1 822) "les Janthines"
(vernacular). First latinized [as lanthinea,
based on lanthina, an incorrect subsequent
spelling] by Children (1823 [in 1822-1824]:
248), with explicit reference to Lamarck, -inae,
Swainson (1840: 195, 210); -oidea, Golikov
