This spedes is ratker variable, and may perhaps include 

 otker forms tkan the akove mentioned oiies, wKick ougkt to 

 be kept distinct. At several places I met witk a {orm py g- 

 nuca on rocks at kigk-water mark. It is only 3—4 cm. long 

 bearing richly receptacles, but as yet I do not know whether 

 it may be regarded only a atunted form produced by nnfa- 

 vourable conditions of life. I have, on the contrary, seen 

 specimens most nearly related to the typical form bearing 

 receptacles even 11 cm. in length. The form latifrons cor- 

 responds with f. grancUfrons of F. serratus and f. vadorum 

 of F. vesiculosus. It generally bears air-bladders of aleng- 

 thened shape until 8 cm. long. The typical form also is 

 provided with such ones, though more seldom. 



The present plant is litoral, mostly occurring in the 

 lower part of the 2one, and åt several placea it forms a 

 rather broad girdle, at others growing in company with 

 F, vesiculosus or F. scrrahis. Although it appears in great 

 abundance at most places along the misheltered part of the 

 coast, the nnmber of individuals seem in general to be less 

 than at West-Finmarken. It bears receptacles in June and 



' ri 



July (f, typica), and in the first part of August (f. vaclonim). 

 The latter grows farther down than the typical 'form, at 

 extreme low-water mark, or perhaps descending into thesub- 

 litoral 7.Qni\ It seems to prefer sheltered localities.
