Diagnosis Medusa manubrium small, usually on rather well differentiated gastric peduncle; 4-6 simple radial canals running from circular canal across underside of bell and along peduncle to manubrium; bulbs with or without excretory papillae; margin with or without cirri or marginal warts; gonads on radial canals, separated from manubriuml; 8 to many statocysts; without ocelli.The hydroids of the Eirenidae can be of 'Campanulina', 'Campanopsis' or 'Eugymnanthea' type. Hydroid colony of benthic species stolonal or ramified erect; bivalve-inhabiting species without perisarc, with pedal disc, usually solitary; planktonic species solitary, polyp budding totally into a single medusa; hydrotheca cylindrical in young colonies of erect forms, with diaphragm and folded pleated operculum formed by convergent flaps not demarcated from the hydrothecal rim; in older colonies of this type, operculum generally lost and hydrotheca reduced to perisarcal collar, of haleciid type; hydrotheca usually reduced or absent in stolonal colonies, hydranth naked, borne directly on hydrorhiza or on short pedicels; hydranth of commensal species elongated, extensile, with filiform tentacles in a single amphicoronate whorl; intertentacular web present; gonophores on hydranths, hydrocaulus, or hydrorhiza, naked or more usually at least initially in a gonotheca, in form of medusae or medusoids with gonads on radial canals.
