Sea-Anemone. Of the stone-depo- siting coral-animals, a large number are often associated in a com- pound structure, as in Fig. 76; this consists of a stony tree-like stem and branches; but in- stead of the soft animal matter being contained in its interior, as in the preceding case, it forms a kind of flesh that clothes the surface, and connects together the different polypes. 134. Some of the stony corals, however, are formed by polypes of a higher conforma- tion ; none of which have yet been disco- vered in a separate con- dition. Our example must therefore be taken FfG 76.—stem of Coral. from one of the compound structures found on our own coasts ;.
