The figure is from Gosse's British Actinology. It also grows much longer in proportion to the breadth. The figure to the right is of one unexpanded. One of its lasso- cells, in different states, is shown in figures 3, 4, 5, on page 81. The corallum of a related species, Oaryophyllia cyaihus^ is given on page 42. The walls and septa are remarkably solid. The Oaryophyllia flavus hdi.^ been found not only in the Mediterranean, but also as far north as the British Isles, and in the Florida Straits. Another example of this tribe, as defined by Prof. Verrill, is the species of Astrangia occurring alive along the southern shores of New England, and on the coast of New Jersey. Specimens are not uncommon in the vicinity of New Haven, on the rocks by the Light-House, and at other places in Long Island Sound, and when alive it is an exceedingly beautiful.
