Contribution. I. 73 



Probably these rings indicate the number of years the plant 

 has existed, answering to the space of time the buoy has 

 been in the sea. The rhachis was provided with sporophylk 

 and showing scars of such organs that had fallen off. 



The species occurs in the upper part of the sublitoral 

 zone, on a depth of 1 — (10?) fathoms, and becomes best de- 

 veloped in rocky and much exposed localities. Specimens 

 with zoosporangia have been collected in July. 



Distribution: Common and abundant at least along the 

 open part of the coast from Svserholt to Kiberg in the neigh- 

 bourhood of Vardo.

I found at Kiberg a specimen of an Alaria, which pro- 

 bably belongs to this species. The stem (including rhachis) 

 had a length of 1.5 m. and a diameter of 2 cm. Of the la- 

 mina only a small portion was left, the costa had a breadth 

 of 17 mm. Judging from other fragments I suppose this 

 species to occur all along the open coast. Thus at Mehavn 

 and Kjollefjord I got fragments of laminse having a breadth 

 of until 50 cm , and fragments of very coarse and long stems. 



Distribution: Common and plentiful (?) along the open 

 coast. 1 



I also met with other forms. But as before mentioned, I have lost 

 the greatest part of my collections of Alaria from East- as well as 

 from West-Finmarken, and the examination of the specimens when 

 collected, and the notes from my excursions are too little particular 

 to record these frrms here, espicially in the case of a genus with so 

 feeble marked forms as Alaria. 



At a sunken rock about two (engl.) miles from the outer side of 

 Kjelmo in Sydvaranger I sow on a depth of 2—3 fathoms an Alaria 

 which reminds of A, Pylaii, but the specimens had a remarkably nar.
