By the kindness of J. G. A g a r d h I have had the op- 

 portunity of examining an authentic specimen of this species 

 from Bohuslan. The Finmarkian specimens coincide fully 

 with that one 3 only smaller and a little thinner. Among the 

 quoted figures it most nearly resembles K ii t z i n g's B. crispa 

 Tab. Phyc. 3, t. 28, fig. a. 



The plant is litoral, occurring on rocks near high-water 

 mark, on exposed coast, together with Calothrix scopulorum. 



Distribution: Only found at Kjelmo in Sydvaranger, 

 rare. 



Bangia virescens nob. 



B. rupicola, luteo-virens; fllis cylindraceis, simplicibus articulatis 

 12—30 [J. crassis, dense intricatis atque crispis, arcticulis aequalibus ad 

 triplo brevioribus. Tab. 2, fig. 2—9. 



The species forms rather thick, uniform and sometimes 

 extensive strata on rocks between tides, mostly at high-water 

 mark in exposed localities. The surface is a little rough or 

 undulate-lacunosed. It has a yellow-green colour, and its habit 

 is rather that of an Urospora than a Bangia. It also some- 

 times grows alternating or mixed with Urospora penicillifor- 

 mis. The thickness of the threads varies between 12 and 

 30 jx, most commonly about 20. They are so densely inter- 

 woven that pretty large parts of the layer may be easely 

 removed from the rock with a knife. 



The plant seems to be dioecious. But I am uncertain 

 whether the organs figured on t. 2, fig. 7 — 9 really are sporo- 

 carps and antheridia. It has been collected with these organs 

 at East Finmarken in July and at West-Finmarken at the 

 end of May. It seems to disappear in August 



Distribution; Pretty common and rather plentiful almost 

 all along the unsheltered part of the coast. I have seen it
