Rediscovery of Cancellaria corrosa Reeve, 1856 (Gastropoda: Cancellariidae) in the tropical eastern Pacific

摘要

Cancellaria corrosa Reeve, 1856, a species described from an unknown locality and believed by early authors to inhabit "China Seas," has been found to be a component of the sublittoral fauna of western Central America. A more detailed description of the shell and radula of this species is provided. As specimens have been misidentified in collections as C. decussata Sowerby I, 1832 or C. gemmulata Sowerby I, 1832, features useful to distinguish these species are provided. Examination of the fossil literature for the region indicates that the lineage giving rise to C. corrosa has been present since at least the middle Miocene.
