Diagnosis

Aliciidae with broad pedal disc. Column in its lowermost part smooth, above this a broad zone with thick stalked outgrowths more or less distinctly radially arranged, which are drawn out distally into several short branches. On the branches, and rarely on the stalks also are found hemispheric vesicles containing microbasic and macrobasic amastigophores. There are few, but branched bands of longitudinal endodermal muscles in the stalks. Upper part (capitulum) of the column short with ectodermal longitudinal muscles. Sphincter indistinct, diffuse. Margin tentaculate. Tentacles numerous (up to about 160), hexamerously arranged with small stinging spots. Longitudinal muscles of tentacles and radial muscles of oral disc ectodermal. 2 rather weak siphonoglyphs. 6 pairs of perfect and sterile mesenteries. Retractors diffuse, weak. Basilar muscles rather well developed. Gonads from the mesenteries of second cycle. Cnidom: spirocysts, basitrichs, microbasic p-mastigophores, microbasic and macrobasic amastigophores.
