The daughter corallite arises from the dissepimental tissue of the parent (Text-figs. 6, 7). In the early stages, the adult corallite becomes egg-shaped in cross-section with the more pointed end containing dissepimental tissue only, the septa having withdrawn from the epitheca in this area. This projection expands in size and septa begin to appear on the wall farthest from the parent. Some septa from the parent itself may extend slightly into the developing individual where the two are joined and these appear eventually to contribute to the latter's full complement of septa. As the process continues, the daughter corallite grows more circular and forms a bilobed complex with the parent. At the same time, new septa are inserted on.
