Preserved: Greenland: off Akuliaruseq (60°09’N. 44°10’W) (140 m), 12 Jul 1970, polyps on steep rocky slope (type with sponge fibers in the hydrorhiza); Cape Farewell Expedition st. 93; southwest Qeqertat (59°52.8`N, 43°31.5`W) (225 m) (no date), 10 polyps without gonophores, on encrusting bryozoans, ZMUC (without collection number). Description. Hydroids 7.3–29.0 mm in height, covered by thick, heavy perisarc, growing on rock, sponge, and encrusting bryozoans. Hydrorhiza swollen, with 1–3 large, strong, club-shaped processes, covered by stiff perisarc. Hydranth large, oblong; hydranth body 1.4–3.7 mm high, 0.7–3.5 mm in diameter at base. Oral tentacles filiform, ca. 40 in number, arranged in five whorls, adnate to hypostome around mouth, tentacles laterally flattened in cross section; most proximal whorl arising at right angles to hypostome, most distal whorl ... : Published as part of Campos, Carlos J.
