Diagnosis Filiferan hydroids with strictly stolonal colonies. Hydrorhiza consisting of a creeping stolon with branches and anastomoses, becoming a dense network; coenosarcal tubes of stolon encased in a sheath of perisarc, not encrusting, or calcareous or covered with naked coenosarc. Hydrorhizal spines and nematophores absent. Zooids monomorphic, consisting of sessile hydranths encased basally in a short, wrinkled sheath of perisarc, otherwise naked. Hydranths of a colony tending to be separated rather than clustered in a dense clump, sessile, highly contractile, elongate and nearly cylindrical when extended, with a slight to distinct bulbous area below a somewhat constricted neck region, bulbous again distally at insertion of tentacles; without carbonate granules in the gastrodermis; tentacles filiform, in two very closely-placed whorls, appearing as a single whorl in contracted hydranths; hypostome dome-shaped. Gonophores fixed and rounded sporosacs without traces of radial canals, ring canal or tentacles, borne on unmodified hydranths, arising in grape-like clusters on hydranth column from a distal band beneath tentacular whorl.  [details]
