Edwardsiidae with the column divisible into scapus and scapulus, the former very long and provided with an usually strong, sometimes very thick cuticle. Aboral end rounded, flattened or rarely physa-like. Scapus without nemathybomes and tenaculi, with nematocysts either scattered or arranged in groups. Scapulus often ridged with numerous nematocysts on the ridges. Tentacles 6+6+12 to about 40, the inner longer than the outer ones. A single, ventral siphonoglyph. Mesenteries as in Edwardsia. Retractors diffuse, fairly restricted, parietal muscles well developed. Cnidom: spirocysts, basitrichs, microbasic b- and p-mastigophors.
