|---|---|---|
| C. W. Merriam 1974 | Medium to large solitary trochoid to cylindrical rugose corals have numerous long, thin, usually fairly smooth septa. The longer septa reach the axis. Cardinal fossula is well defined to weak, without pronounced pinnate arrangement of several bordering septa. The dissepimentarium is wide, with multiple columns of steeply inclined mostly small dissepiments. The tabularium is wide or medium wide, consisting of a variable complex of partial to nearly complete, straight or bowed tabulae that are peripherally bor- dered by large tabellae passing into dissepiments laterally. Conspicuous vertical gaps commonly separate the tabluae. Outer wall is thin, lacking a peripherally continuous septal stereozone. |
