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.
|A. Boczarowski 2001||Aboral side of central disc is highly swollen, encrusted by network with radiate spicules. Arms short and wide, ambulacrals with thin, big groove. Laterals with wide, strong juncture. Very long, thin spines consist of three blades.|
|J. Dean Shackleton 2005||Loss of inferomarginals; loss of inferomarginal spines; loss of buccal slits.|
