A h 1 n e r lias bad the kindness to examine my collec- 

 tions of Enteromorpha. He has with doubt referred to the 

 present species a couple of specimens from East-Einmarken. 

 They grew in the litoral zone attached to Halosaccion ra- 

 mentaceum. 



Distrihution: Only found at Sværholt; very rare.

Litoral, growing on sandy localities, or in rock-pools 

 at high-water mark, on open coasts as well as sheltered 

 ones. It attains a length of about 35 cm., and it is fur- 

 nished with zoospores in July. 



Distribution: Apparently pretty common olong the whole 

 coast. I have seen it at KjoUefjord, Meljayn, Sylte^ord 

 (pretty plentiful)^ Vadso (abnndant), Bngonæs and Kjelmo 

 in Sydvaranger.
