Habitat. Epiphytie on litoral alge, as Corallina officinalis, Asperococcus echinatus, 
Scytosiphon lomentarius, Dictyosiphon hippuroides a. 0., which are sometimes completely 
covered by it. I have met with it only on exposed coasts. It bears zoosporangia in 
July and August on the arctic coast of Norway. 
Geogr. Distrib. It belongs to the Atlantic region of the Polar Sea. Its northern- 
most point is Oxfjord in Finmarken about Lat. N. 70°. 
Localities: The Norwegian Polar Sea: Nordlanden at Gjesver; Finmarken local, 
but rather abundant at Oxfjord.

1) By the sign of interrogation I have meant to denote that I am uncertain if this genus belongs to the 
family of Ectocarpacee.
