Desniotrichiim iindnlntum , Punctaria laiifolia, Litosiphon filiforme, 

 Phæostromd parasiticiim, Phiillitis zosterifolio , Desmarestia ligulata, 

 Chorda tomentosa, Laminaria færoensis. It is most probable, lliat 

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

 ther investigalion, the lemainding species are partly some that 

 grow in more southern regions and most probably do not occur 

 in Nordland, partly the species hitherlo found at the Færoes only, 

 of whose occurrence oulside the Færoes we know nothing as yet. 

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

 oes but not hitherto at Nordland, namely: Chlorochijtrinm inclii- 

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

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

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

 maritima, Ulvella fucicola, U. confluens, Pringsheimia scutata, 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- 

 loivii, Pleurocapsa amethijstea, Hyella cæspitosa, H. endophytica, Spi- 

 rnlina subsalsa, Phormidium autumnale, Lyngbya lutea, Microcoleus 

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

 probably a great number of these species will likewise be found 

 in Nordland. 



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

 to papers by Foslie; Kjell man, however, has also contributed 

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

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

 algæ are common to the Færoes and Finmark, that is 91 in all 

 or 58 °/o of the Færoese algæ and 72 % of those of Finmark. The 

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

 are as follows: Chantransia microscopica, Turnerella Pennyi, Polysi- 

 phonia arctica, Spermothamnion Turneri, Ceramium Deslongchampsii, 

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

 matolithon inuestiens, 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, Phæo- 



' Kl een, however, mentions both a Cladophora arcta and a Cl. uncialis, 

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

 Spongomorpha mentioned here.
