This spedes is litoral as well as sublitoral. In the lito- 

 ral zone it grows in rock-pools, on rocks or attaclied to 

 shells (chiefly Mytilus) in the lower part of the zone. In 

 the suhlitoral zone it descends to a depth o£ 10 fathoms 

 and principally covers smaller stones^ It is most ahnndant- 

 ly met with on a depth of 1 — 3 fathoms and at some pla- 

 ces (for inst. KjoUefjord) growing in as considerahle num- 

 bers as to give the vegetation its character. It occurs as 

 well on exposed places as on sheltered ones. I have tåken 

 tetraspore-specimens at the end of June, in July and in the 



beginning of August. 



Dlstrihution : Pretty common almost everywhere, at 



some places abundant.

I have met with a few certain specimens of this plant, 

 which till now has been foiind only at loeland. The spe- 

 cies approaches very nearly to the preceding one^ as the 



r 



åuthor remarks himself. To me it seems doubtful whether 

 it can be specifically distinguished from the former. The 



plant grows on similar localities as L. Lenormandi. Tetra- 

 spore-specimens have been collected in July. 



Bistribittion : Found at Mehavn and at Kirkenæs in 

 Sydvaranger. Perhaps it is more commonly dlstributed and 

 some of my notes on L. Lenormandi really refer to L. læve. 



Lithophyllum zonatum nob. 



In the most eastern part of the district I found a so- 



1. Perhaps it descends to a still greator depth. In Troniso amt it is aubli- 

 _., toral as well as elitoral, descending to a depth of ^bout 30 fathoin«.
