Corallimorphidae with often irregular margin. No distinct sphincter. Tentacles short, simple, the distal end [sic] with weak acrospheres, containing spirocysts and the same nematocysts as in Corynactis. No distinct difference between the dicyclic (?) marginal tentacles and the smaller discal tentacles which are arranged in simple radial rows with 2 to many tentacles in each row. No siphonoglyphs. Directive mesenteries present or absent. Retractors rather weak. Parietobasilar muscles very weak, not folded. Vertical fission common, resulting when incomplete in individuals with up to seven mouths. The individuals often live aggregated in patches. Cnidom: spirocysts, holotrichs (atrichs?), microbasic p-mastigophors.
