Worms XIV. Vol. VII. No. 3., THE WINDING SERTULARlA OR VESICULAR CORALLINE. (Sertularia volubilis, Linn. S. uniflora, Pallas.), About the trunk and tire branches of a red prickly coralline winds an other species of zpophytes, belonging to the genus Sertularia oxvesicular coralline, represented in its natural greatness in Fig. . 1. and magnified in Fig. . 2. of the annexed table. This ;winding seitularia has the appearance of a .plant, as well as all the plant-animais, inhabiting the Océan; but its substance is white, .horney, elastic, flexible and half transparent, rwhose united and subile filaments form an articulated , tortuous and filaceous stalk, .which serves as a shelter to particular polypes, adhering to it and dwelling in seperate cells (even hère indistingûishable) of thèse articulations, from whence they extend their armed fangs to catch their food. The little bells, with a dented border, on the long and articulated stalk$,of.the trunk of the sertularia, are open and transparent cases, looking like vesicles, which, in the hottest summerseason shoot out of the sertularia, and wherein form themselves oval burgeons, either cleaving to the principal trunk, or separated from if. From such burgeons issue new sertularia.s, which continue growing. The polypes of the sertularias feed upon the least and most tender microscopical worms, living in the sea-water.
