I have met with this species only once. It grew faste- 

 ned to Chcetomorpha melagonium within the upper part of the 

 sublitoral zone, on a depth of about 3 — 5 fathoms. 



Distribution: Only found at SvaBrholt, rare. I think it 

 more commonly spread along the open part of the coast.

I found a few sparingly branched and barren specimens 

 of a Chantransia, appearing to belong to this species. They 

 grew epiphytic on Sphacelaria arctica within the litoral zone. 



Distribution: Only found at Svserholt and Syltefjord, rare.

As citied by K j e 1 1 m a n (1. c.) one of the forms of this 

 species, found in the Norwegian Polar Sea, seems no doubt 

 identic with the form described and figured by F a r 1 o w 

 under the name of Trentepohlia virgatula, and th^s form again 

 I consider to be identic with Kiit zing's Callithamnion pili- 

 ferum from Bretagne (Tab. Phyc 1. a). Farlow quotes
