The margin of the tentaculiferous disc has no coloured bodies, and the tentacles are conical. It was called Anthea by Johnston. Anemonia cereus has from 100 to 200 tentacles longer than the body, and they are green, or olive and brown tipped with rose, with a brown disc, with gi-een radii. It inhabits the rocks of the English Channel. Anemonia tuedia, with short tentacles, inhabits the Scottish coasts. Other genei-a have coloured bodies on the outside of the disc. The genus Actinia has tentacles that can be retracted, and it has the chromatopliores, or coloured bodies. Actinia mesembryan- theiiium is the common Red Sea Anemone of the south of England, and it is a hardy thing, liking to get out of the water now and then on to the rocks, and to remain there closed, and then to re-enter by crawling with its disc. It is very voracious, and grows to a moderate size, and lives years in confinement. Actinia amjuicoma and A. pallida are also English species. The genus is found in all tlie northern seas, the Medi- terranean, the Atlantic, and on the Pacilic coasts. Moseley has described Actinije from 1,075 to 1,350 fathoms' depth in the Atlantic, clinging on to the stems of a Mopsea. The genus Paractis of the South Seas and Atlantic has no chromatopliores. The pretty Diantlms Anemone belongs to the genus Actinia, and has its disc lobed. An allied genus is that of Discosoma, and it contains a huge foim, which measures two feet across,, Mhah 111', flit like x l iijiet on the mud of tlu Eed Sea This genus is Mediterranean and Pacific in its distribution.* The Kenus Corynactis has the ten- tacles swollen and sub-spherical at their ends, and Melactis has a protractile mouth and knobbe
