Among the 42 species that are indicated as spread over 
tlie whole province we find again the widely distributed species 
of 1. in table III with two exceptions, Laminaria cuneifolia , only 
fonnd (?) in the White Sea, and Rhodymenia palmata not known 
from Spitzbergen. Most of tlie others are widely spread. Of 
special interest however are Maria grandifolia and Laminaria 
Agardhii , which perliaps are confined to this area and Scapho- 
spora arctica that only here enters the arctic regions. 
Of the species which enter the arctic Sea along the north 
coast of Enrope 5, viz., Dictyosiphon corymbosus , Eudesme vires- 
cens, Porphyra umbilicalis , Chantransia secundata , and Polysipho- 
nia urceolata are also found in Western Greenland. It certainly 
is dne to the favourable conditions of immigration, that these 
niostlv atlantic algae here have reached so far north, as is also 
the case witli: Mesogloia vermiculata, Pelvetia canaliculata , Cysto- 
clonium purpurascens, Polysiphonia nigrescens, Dumontia filiformis 1 
Polyides rotundus, Lithothamnion Lenormandi , Corallina offici- 
nalis , all species tliat nowhere eise belong to the arctic regions, 
likewise as witli Lithosiphon Laminariae , if that alga is really 
found on the coast of Novaja Seinlja. On the other side Laminaria 
cuneifolia , an arctic-pacific species, here should have its limit, if 
the plant found in the White Sea is rightly determined by Oobi. 
Among the 9 species indicated only for Spitzbergen 3 are 
endende, viz., Turnerella rosacea , Rhodochorton intermedium, Rh. 
spetsbergense. Ceramium arcticum, lately described by Agardh 
(6), is also known from northern Eorway. Maria esciüenta is 
dubious and perliaps also Rhodymenia pertusa , which is a paeihe 
species nowhere found in arctic waters. R osenvinge (42, p. 811) 
has shoAvn, that Grreenkind-speciniens conveyed by Ivjellman 
to this species are Rh. palmata, and the same perliaps is tlie 
case witli the Spitzbergen specimens. It also would be astoun- 
ding if the latter, common species there should be substituted 
by such a traveller from afar. Fucus ceranoides only here enters
