| W. J. Sando 1983 | etalaxis with corallite diameter 3.5 to 6 mm and 12 to 16 major septa that extend about halfway to the columella but seldom extend into the dissepimen-tarium. Minor septa absent or poorly developed. Col-umella ranging from a simple axial plate connected to the counter septum to a complex structure composed of an axial plate, vertical axial tabellae, and a few septal lamellae. Dissepimentarium composed of 1 to 2 rows of large inflated dissepiments. Tabulae mostly incomplete, flat to concave, horizontal, and irregularly spaced 0.25 to 0. 75 mm apart. Ratio of tabularium width to corallite diameter about 0.6. Mode of increase unknown. |
