Perrier, 1884

Starfish with generally inconspicuous marginal plates; there is no sharp limit between dorsal and oral side of the disc and arms. The spines on the dorsal side are single, or in groups, which may be arranged in longitudinal series.

Tube-feet and pedicellariae
The tube-feet are mostly in four series, never with a sucking disc. Both crossed and straight pedicellariae are present. The presence of crossed pedicellariae is characteristic for this Order of starfish.
