Sycon coronatum sensu Row 1909
Other than the size of the specimen and its fringe, Row (1909: 185) has not described this material. This European species described by Ellis & Solander 1786 (as Spongia) is considered a junior synonym of S. ciliatum (Fabricius, 1780) . It is unlikely that the Red Sea specimen belongs to that species. This record remains incertae sedis.
