elongated obovate. The stipe ig very thin in the lower part, 

 and is not always passing into the club withont any limit. 

 By Finmarkian specimens the club sometimes is soraewhat 

 thicker in proportion to the length than by specimens from 

 the Paroe Islands, but otherwise coinciding with one ano- 

 ther. The plant is smaller, and it has another general ap- 

 pearance than C, cylindraceum, the strata being thinner and 

 the colour a little paler, and often it grows together with 

 other smaller algæ, especially Phycochromophyccæ. 



I have seen it growing almost side by side with the 

 named species, on rocks in the upp er part of the litoral zone.

In the above quoted paper I made a mistake in refer- 

 ring the present plant to C. cylindraceum. I thence only 

 saw it in smaller number, and in some respects resembling 

 (7. cylindraceum I thought it ought to be referred to that 

 species. Later I have found it in rather considerable abun- 

 dance, and now it seems to me notto be referrible to the na- 

 med species. It is, like theother species of the genus, rather 

 variable, and perhaps most nearly related to (7. pusillum, 

 but the club is longer than the stipe and generally a little 

 thicker, and often also with a rather distinct limit between 

 the stipe and the club. On the other hand it resembles G» 

 NordcnsMoldianum by the club being longer than the stipe 

 and often elongated-obovate. But it seems to be a larger
