If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

R. M. Finks 1960Massive, with radial architecture; skeletal net dense but separated by canal system into continuous radial trabeculae connected at right angles by similar trabeculae; ends of radial trabeculae projecting
strongly above surface; radial canals long and continuous, connected by horizontal canals corresponding to meandriform, anastomosing
grooves at surface; large oscules present; imperforate basal layer may be developed.
