This species is literal as well as sublitoral. In the lito- 

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

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

 the sublitoral zone it descends to a depth of 10 fathoms 

 and principally covers smaller stones 1 . It is most abundant- 

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

 ces (for inst. Kjollefjord) growing in as considerable num- 

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

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

 tetrasp ore-specimens at the end of June, in July and in the 

 beginning of August. 



Distribution : Pretty common almost everywhere, at 

 some places abundant.

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

 which till now has been found only at Iceland. The spe- 

 cies approaches very nearly to the preceding one, as the 

 author 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. 



Distribution : Found at Mehavn and at Kirkenaes in 

 Sydvaranger. Perhaps it is more commonly distributed and 

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



Lithophyllum zonatum nob. 



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



1. Perhaps it descends to a still greater depth. In Tromso amt it is subli- 

 toral as well as ejjtoral, descending to a depth of about 30 fathoms.
