Galeodea is a highly speciose, almost cosmopolitan genus (taking the many fossil species into account) recognisable by its sculpture of many narrow, rather widely spaced, prominent spiral cords, strengthened or grouped into wider cords at the nodule rows in many species, and raised into 1-5 or more rows of narrowly rounded, small to quite large nodules on the last whorl of most species; by its moderately long, narrow, slightly twisted, unnotched anterior siphonal canal, rather than the very strongly twisted, deeply notched, fasciolate, dorsally directed anterior canal of the superficially similar phaliine genus Echinophoria by its weakly thickened and slightly flared to prominently varicate outer lip, with ridges or nodules on the inner edge in many species; and by its narrowly oval operculum (with the upper left margin weakly to moderately deeply embayed to accommodate the parietel bulge in most species) with its nucleus at or near the anterior third to half of the height near the right (abaxial) opercular margin.
