Diagnosis Hydroid usually on rim of sabellid polychaete tubes, with creeping, naked stolons; hydranths almost sessile, polymorphic;gastrozooid with rounded hypostome, separated from body by a constriction; hypostome with large pad of nematocysts somewhat displaced onto one side, two filiform tentacles arising close together beneath hypostomial constriction, opposite to nematocyst pad; gonozooids and dactylozooids without tentacles, mouth-less and smaller than gastrozooids; medusa buds close to gonozooid tip. Medusa umbrella mostly hemispherical; with exumbrellar nematocyst buttons or bands alternating with tentacles; radial canals branched, obliterated canals some times present; usually instead of circular canal a solid gastrodermal marginal strand; manubrium base with four, six or more radial canals and gastric lobes, extending along proximal portions of radial canals, lobes in some species inconspicuous; gonads surrounding manubrium and extending onto gastric lobes; tentacles hollow, with swollen hollow base connected to the lumen of radial canals.
