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.
|D. B. Blake and D. R. Elliott 2003||Primary circlet weakly enlarged; interadials, radials, nearly equisized, transversely elongate; "extraneous" or "x" ossicle not developed. Carinals in single series, ossicles not abutted; no lateral series. marginals in single series, robust, equidimensional; marginals, adambulacrals together forming rounded arm margin. Axillary absent. Ambulacrals, adambulacrals offset, two podial pore rows present.|
