Open and finely btiilt, zigzag and sHghth' branched upright colonies with Uionosiphonic stem. The stem and branches are divided into short internodia which form an angle one with another, and are more or less distinctly ringed, more rareh- quite smooth. From the same iuternodiiun may often proceed two or three branches, or simple internodia. The large, somewhat spindle-shaped hydrothecae are situate on the outer half of the internodium, and are very slighth- embedded; the opening part is again as a rule somewhat expanded; the aperture is set perpendicularly to the axis, and has four not very prominent teeth, between which are attached four triangular lid plates. The gonothecae are attached to the branches or stolons. They are elongated o\-aI to egg- shaped, in the latter case with the broader part somewhat below the middle. The gonotheca has a distal central aperture with four strong teeth. Material: "Ingolf St. 3 63°35' N., io°24' W., depth 272 fathoms, 0,5". The Ingolf-Expedition. V. 7. 14.
