Characteristics
Elongate Halcampidae with the column divisible into physa, scapus and capitulum. Physa small, often flattened, not ampullaceous, probably without pores. Scapus with cuticle and tenaculi. Capitulum with scarce spirocysts. Sphincter simple, weak, extending a little into the base of the tentacles. Tentacles always more than 12, short. Siphonoglyphs indistinct. Mesenteries arranged at least in two cycles, divisible into macro- and microcnemes. Only the mesenteries of the first cycle perfect, fertile and with strong reniform to circumscribed retractors. Parietal muscles well developed. All mesenteries extended over the whole length of the column. Same number of tentacles and mesenteries. Cnidom: spirocysts, basitrichs, microbasic p-mastigophors.References
