Note
The cubomedusa Carybdea marsupialis and the rhizostorne scyphomedusaPhyllorhiza punctata are reported from waters of California and the easternPacific for the first time. Previously, C. marsupialis was only known from theAtlantic Ocean. It apparently is native to this area but was confused with Carybdearastoni which is known from Hawaii and the central and western Pacific. P.punctata was recently found in San Diego Bay, previously it was known in thePacific from Hawaii and the tropical Indo-Pacific. Its recent appearance in Californiawas probably due to transport of polyps on the hulls of ships. A synopsisof cubomedusae and scyphomedusae from the waters of California is presented; a total of 19 species are known.
