of Ehisoclonium torfuosum, A specimen communicated to me 

 by Hauck, in habit greatly resembles Conferva fortuosa 

 Wyatt, Alg. Danm. Nr. 190, but, as I have stated before,

I have seen specimens from the southern Norway 



sum. 



which almost fuUy coincide with Adriatic ones, and also 

 transitions between the naraed forms. 



The present species, on the coast of Finmarken, has 

 only been found in sheltered localities, in the inner part of 

 deep bays. Specimens coUected in the beginning of July

Distrihutton: Found at Kirkenæs in Sydvaranger, lo- 



cal but pretty plentiful.

This plant is at first fastened to other algæ, but af- 

 terwards is getting loose, forming tanglei masses. I m^t 

 with it fastened to Didyosiphon hippuroides and Cladophora 

 gracilis, or loosely entangled with the latter and EhizoclO' 

 nium rigidum, or jointly with other algæ. It is chiefly li- 

 toral and is fre(iuently met with in rock -pools, on open as
