In spite of the luxuriant development which it attains in the Trondhjem Fjord, it must probably, like Corymorpha groenlandica (Allman), Myriothela fhrygia (Fabricius), and Stegopoma plicatile (G. O. Sars), be accounted for as an arctic relict in this locality.

Colonies whose long polyp stems, generally unbranched and irregularly curved, are separated quite down to the tangled network of basal tubes. The stems are covered with a fairly vigorous, but colourless perisarc, which is irregularly wrinkled or more rarely quite smooth. The polyp wears a basal whorl of up to 25 tentacles, attaining a length of 8 mm.; the numerous distal tentacles, 2 or 3 mm. long, are densely crowded round the orifice in a whorl consisting of several rows. The gonophores are eumedusoid, without radial canals, but with a rudimentary circular canal; they are most frequently provided with three rudimentary tentacles. The gonophores are supported by 6â12 short blastostyles, which may be erect or hanging. The actiuula larvae, when deliberated, show filiform tentacles. Material: Iceland: Reykjavik.
