Portion of a filament with tetraspores and glands. Besides the main form I found the above-mentioned variety and form; I follow Rosenvinge in regarding these as forms be- longing to this species. The specimens re ferred to var. boreale agreed fairly well with Kjellman's figures, but sometimes the tetrasporangia had a uni- cellular stalk. The specimens bear quantities of glands (cfr. Rosenv., Grønl. Havalg., p. 788). I have figured (fig. 59) a small portion of one of the specimens which are referred to formå corallina, as they differ somewhat from Kjellman's ligures; the branches of the second order were more rigid and graceful in form, like a feather, being set with branches of a third order which gradually shortened towards the apex.
