The type species of the genus Acteocina, Acteon wetherilli Lea, 1833, is synonymized withVolvaria canaliculata Say, 1826, type species of the genus Utriculastra; because Utriculastra and Cylichnellaare synonymous, Acteocina is the senior synonym. The systematics of A. canaliculata and A. atrataspec. nov. are examined, and a neotype is designated for A. canaliculata. Descriptions are presented ofshell, radular, and gizzard plate morphologies; geographic and bathymetric distributions are re-evaluatedbased on museum collections. Floridian specimens of A. canaliculata have planktotrophic development,hatching in 4 days and settling in 24 days; A. atrata has capsular metamorphic development,hatching in 9 days as benthic juveniles. A preliminary review of Acteocina candei (d'Orbigny, 1841) isgiven, and a lectotype is designated. Acteocina candei distinctly differs conchologically from A. canaliculata,is resurrected from synonymy, and is considered a valid species.
