of the Conoidea.. The type species of ''Fusiturricula'', ''Turris fusinella'' Dall, 1908, is even different from what is currently conceived as belonging to that genus, but those species are similar to ''Cruziturricula'' ''sensu auctt.'' Although ''Fusiturricula'' (and ''Cruziturricula'') definitely do not belong in the family Drilliidae (they may represent a new family), they are assigned in the Drilliidae provisionally as a working hypothesis.
