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.
|G. Breton 1978||Arms relatively long (R>2r). Architecture of the arm with rows of carinal, superomarginal, inferomarginal plates to the arm tip and a row of actinolateral reduced to the arm base. Carinal, superomarginal and inferomarginal plates in equal number. Localy, few intermarginal plates of reduced size. Superomarginal and radial plates notably wider than long in the larger part of the arm (l/L equals two). Inferomarginal, superomarginal and carinal plates low. External face of superomarginal plates slightly domed, with ornament of fine, dense granule pits. No raised central area differentiated.|
