Among the 42 species that are indicated as spread over 
the whole province we find again the widely distributed species 
of 1. in table III with two exceptions, Laminaria cuneifolia , only 
found (?) in the White Sea, and Rhodymenia palmata not known 
from Spitzbergen. Most of the otliers are widely spread. Of 
special filterest however are Alaria grandifolia and Laminaria 
Agardhii , which perhaps 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 Europe 5, viz., Dictyosiphon corymbosus , Eudesme vires- 
cens, Porphyra umbilicalis , Chantransia secundata , and Polysipho- 
nia urceolata are also found in Western Greenland. It certainly 
is due to the favourable conditions of immigration, that these 
mostly atlantic algae here have reached so far north, as is also 
the case with: Mesogloia vermiculata, Pelvetia canaliculata , Cysto- 
cloniurn purpurascens, Polysiphonia nigrescens, Dumontia filiformis , 
Polyides rotundus, Lithothamnion Lenormandi , Corallina offici- 
nalis , all species that nowhere eise belong to the arctic regions, 
likewise as with Lithosiphon Laminariae , if that alga is really 
found on the coast of Novaja Senilja. 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 Gobi. 
Among the 9 species indicated only for Spitzbergen 3 are 
endemic, viz., Turnerelia rosacea , Rhodochorton intermedium, Rh. 
spetsbergense. Ceramium arcticum, lately described by Agardh 
(6), is also known from northern Norway. Alaria esculenta is 
dubious and perhaps also Rhodymenia pertusa , which is a pacific 
species nowhere found in arctic waters. Rosenvinge (42, p. 811) 
has shown, that Greenland-specimens conveyed by Kj eil man 
to this species are Rh. palmata , and the same perhaps is the 
case with 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
