Aurelianidae with very wide pedal disc. Column without vesicles, smooth, divisible into scapus and capitulum, the former with a more or less distinct periderm, the latter containing spirocysts which are absent or almost so from the scapus. Fosse distinct. Sphincter fairly to very strongly pinnate circumscribed, with a distinct central axis of the mesogloea. Tentacles short, simple or somewhat lobed, comparatively few, arranged in cycles; two tentacles communicating with each main exocoel, two to four (six) with each main endocoel. Longitudinal muscles of tentacles and radial muscles of oral disc chiefly mesogloeal. One siphonoglyph. Mesenteries more numerous proximally than distally. All stronger mesenteries perfect, fertile and with strong pinnate, circumscribed retractors. Parietobasilar and basilar muscles well developed. The weaker mesenteries, in the proximal part of the body, without filaments. Cnidom: spirocysts, basitrichs, microbasic p-mastigophors.
