Desmotrichuni iindiilatiim , Piinctaria laiifolia, Litosiphoi} /Hi forme, 

 Phceostroma parasiticiim , Phijllitis zosterifolia , Desmarestui lif/ulata, 

 Chorda tomentosa , Laminaria fceroensis. It is most probable, that 

 a great many of these 'species will be found in Nordland on fur- 

 ther investigation, tlie reniainding species are partly some that 

 grow in more soutliern regions and most probably do not occur 

 in Nordland, partly the species hitherto found at the Faeroes only, 

 of whose occurrence outside the Faeroes we know nothing as yet. 

 Of green and bluish-green species 40 have been found at the Faer- 

 oes but not liitherto at Nordland, namely: Chlorochijtrium inclu- 

 siim, Codiolum gregarium, C. piisiUiim, Enteromorpha Linza, Pra- 

 siola crispa ''marina, P. fiirfuracea, Ulothrix consociata, U. pseudo- 

 flacca, U. flacca, Endoderma Wittrockii, Acrochaete repens, Pilinia 

 maritima, Ulvella fucicola, U. confluens, Pringsheimia sciitata, Uro- 

 spora Wormskioldii , Spongomorpha vernalis, Acrosiphonia flagellata, 

 A. incurva, A. grandis, A. hystrix^, Cladophora sericea, Gomontia po- 

 lyrhiza, Ostreobium Queketti, Derbesia marina, Vaucheria coronata, 

 Valonia ovalis, Chlorogloea tuberculosa, Dermocarpa violacea, D. Far- 

 lowii, Pleurocapsa amethystea, Hyella ccespitosa, H. endophytica, Spi- 

 rulina subsalsa, Phormidium autumnale, Lyngbya lutea, Microcoleus 

 tenerrimus, Calothrix ceruginea, C. scopulorum, Rivularia atra. Most 

 probably a great number of tliese species will likewise be found 

 in Nordland. 



What we know of the algae-flora of Finmark is mostly due 

 to papers by Foslie; Kj ell man, liowever, has also contributed 

 important information. According to our list, 125 red and brown 

 algae have been found there. Of these algae 50 red and 41 brown 

 algae are common to the Faeroes and Finmark, that is 91 in all 

 or 58 Vo of the Faeroese algae and 72 % of those of Finmark. The 

 34 species which are found at Finmark but not at the Faeroes 

 are as follow^s: Chantransia microscopica, Turnerella Pennyi, Polysi- 

 phonia arctica, Spermothamnion Turneri, Ceramium Deslongchampsii, 

 C. cincinnatum, Petrocelis Middendorffi, Peyssonnelia Rosenvingii, Phy- 

 matolithon investiens, Lithothamnion flavescens, L. foecundum, L. in- 

 termedium, L. fornicatum, L. tophiforme, L. norvegicum, Lithoderma 

 lignicola, Ralfsia deusta, Ectocarpus terminalis, E. nanus, E. ovatus, 

 E. penicillatus, Myriotrichia fdiformis, Sphacelaria racemosa, Phceo- 



* Kleen, however, mentions both a Cladophora arcta and a CI. uncialis, 

 which are most probably identical with some of the species of Acrosiphonia and 

 Spongomorpha mentioned here.
