The floor of the cavity is covered with papillary emi- nences, which are very rough, with irregular points, and are identical with the lower edges of the principal plates, by the convergence of which they seem to be formed. Platc-i. Thin above, but increasing in thickness below, scarcely salient, unequal, straight, the surfaces set with irregular granular tubercles, which become increasingly rough and prominent below. The edges are strongly but in-egularly notched and toothed, especially below; but the upper edge of the^>"mar/e^ is for the most part sub- entire ; the form of the outline varies much. There are normally four cycles in six systems : but the fourth cycle is always wanting either in the whole or in half of some of the systems ; the amount of defection varying much in dif- ferent corallites. The development is very un- notLANt:iA equal, and the plates of the third or fourth {mafjnified). cycle are occasionally larger than those of higher rank, even in the same system. Size. Individual corallites one-eighth of an inch in diameter, and nearly one fourth in height. Animal. Undescribed. Locality. "Weymouth Bay: deep water. When tins neat and interesting little Coral first came into my hands, I thought, notwithstanding some peculiarities, that it must be referred to the Phyllangia Americana, a native of the West Indian seas, and so announced it. But I see that there are incongruities which prevent its identification with that or any other recognised genus, and I have therefore founded a new one to receive it. It has much in common with Anr/ia, as well as rhijUavgia, but the above diagnosis will, I think, warrant my decision. In forming a generic name, I have followed the plan of M. Milne Edwards in using a common element for the genera of a given family ; thougli perhaps a little heterodox f
