Diagnosis

Actinoscyphiidae with the pedal disc definite but sometimes very small and often embracing worm-tubes or needles of Hyalonema. Column thick to very thick, smooth. Tentacles arranged in two cycles at the margin of the wide oral disc, and provided with mesogloeal swellings at the bases of their outer sides. Longitudinal muscles of tentacles and radial muscles of oral disc ectodermal. Sphincter mesogloeal, weak in comparison with the size of the body. Siphonoglyphs well developed. Mesenteries more numerous than tentacles. Six pairs of perfect and sterile mesenteries with diffuse retractors, other mesenteries, at least the older ones, fertile. Animals of fairly large size. Cnidom: spirocysts, basitrichs, microbasic p-mastigophores.
