Abstract
Abstract.—The bopyrid isopod species Bathygyge grandis Hansen, 1897, a reported parasite of several species of the genus Glyphocrangon (Caridea, family Glyphocrangonidae) worldwide, is fully described for the first time on the basis of material collected off the coast of southern California, the closest collection known to the type-locality of the species. Included are a complete synonymy and a discussion of the systematic position of the genus Bathygyge.
