Diagnosis
Hormathiidae with well developed base which is often attached to shells. Column divisible into scapus and scapulus, the former provided with tubercles sometimes showing a tendency to be arranged in rows, more rarely most of the tubercles are reduced so that only a ring of tubercles, coronal tubercles, remain, in the uppermost part of the scapus. In young specimens the tubercles are often small or absent. Scapus usually with a more or less strong cuticle. Tentacles without mesogloeal swellings on their outer sides, not more than 96 (or exceptionally a few more). Same number of mesenteries proximally as distally. Longitudinal muscles of tentacles and radial muscles of oral disc ectodermal, the latter sometimes meso-ectodermal. Two well developed siphonoglyphs. Retractors diffuse.
