Tornidae is a family of very small and minute sea snails with an operculum, marine gastropod mollusks in the clade Littorinimorpha. This family used to be known as the Vitrinellidae. Iredale has shown that the family Adeorbidae Monterosato, 1884 should be called Tornidae
Family names cited with two dates (the second one in parentheses) are those ruled by Article 40(2) of ICZN. "If ... a family-group name was replaced before 1961 because of the synonymy of the type genus, the replacement name is to be maintained if it is in prevailing usage. A name maintained by virtue of this Article retains its own author [and date, the first date cited] but takes the priority of the replaced name [the date cited in parentheses, here alluding to Adeorbidae Monterosato, 1884]
