Diagnosis
Hormathiidae either with a flat adherent pedal disc or with a cup-like base which encloses a cavity full of mud or foreign matter such as small stones. Column usually elongate divisible into scapus and scapulus, the former tuberculate and provided with a weaker or stronger cuticle. Arrangement of the tubercles variable, sometimes they show a tendency to form longitudinal rows. Coronal tubercles mostly 12 or a multiple of 12, sometimes merging into ridges of the scapulus. Scapulus usually with 12 ridges, which are sometimes broken up into tubercles. No cinclides. Tentacles 96 in number or a few more, hexamerously arranged. All the tentacles or at least some of them more or less distinctly thickened on the aboral side at the base. Longitudinal muscles of tentacles ectodermal, radial muscles of oral disc ectodermal or more or less mesogloeal, not decidedly stronger over the exocoels than over the older endocoels. 2 well developed siphonoglyphs. Pairs of mesenteries 48 or a few more, 2 pairs of directives. No more mesenteries distally than proximally. Retractors of mesenteries as a rule diffuse.
