I have not seen Unger's description of this species but 

 by comparison of specimens from Tromso, determined by 

 K j e 1 1 m a n, it also occurs at East-Finmarken. Here it some- 

 times attains a considerable size. I have taken specimens, 

 which were about 22 cm. long, 18 cm. broad and 9 cm. high. 

 However, it seems to be rather much varying as to form 

 and ramification. All the specimens collected at East-Fin- 

 marken belong to the typical form, but from Malangen and 

 other places in Tromso amt I have specimens which are so- 

 mewhat differing. They will be described by a later occasion. 



The species is always sublitoral and oftenest occurs 

 on sandy and shingly bottom within the upper part of the 

 zone, on a depth of 3 — 10 fathoms water. It thrives best 

 on sheltered places and is seldom met with on open shore. 

 At East-Finmarken I have taken tetraspore-specimens in the 

 beginning of August, in Tromso amt in June. 



Distribution : Found at Kjelmo in Sydvaranger, pretty 

 plentiful but local, Vardo and Havningberg, scarce.

A few specimens of this alga I found attached to L, 

 glaciale within the sublitoral zone on a depth of 4 — 6 fa- 

 thoms, and to stones and shells of Balanidse on a depth of 

 10 — 15 fathoms water. .It bears tetraspores in July. 



Distribution: Found at Kjelmo and Kirkenses in Syd- 

 varanger, rare.
