Alcyonium, Lobularia, Cydonium. Fig. Cydonium Midleri. {After Muller.) * Family 2.— CORALLIDJE. Polypes irregu- larly scattered, and more or less prominent upon the surface of a polype tree or common stem, which is arborescent, fixed by a base- ment, and composed of a solid, horny or cal- careous axis enveloped by a sort of gelatino- calcareous living cortex. Corallium, Isis, Gorgonia, Antipathes. Family 3. — MADREPORID^E. Polypes in- habiting cells distributed over the surface of a stony polypary, which is fixed, and generally arborescent. The cells are small, sub-lamel- lated, and constantly porous in the intervals and in their walls {fig. 22). * Zool. Dan. tab. 3 & 4.
