Diagram showing the order of appearance of the septa in a corallite with three cycles of entosepta () and an outer cycle of exosepta ( X.). The Roman numerals indicate the cycle to which the septa belong and the letters their sequence in the cycle. Studies on the mesenterial sequence of other corals indicate that a similar septal succession will in all probability be followed by most forms in which the adult calice shows a regular hex- ameral cyclic plan. Individual departures from the order may be expected, but are to be looked upon as irregularities ; regu- larity of growth of the higher cycles of mesenteries and septa is.
