served, on tlie contrary lie speaks of quite a net of currents in 
the Polar Sea, where an alga must move from one stream to 
anotker if it should make such a voyage. Kjellman rightly 
observes that such a complicatecl drift can hardly be thought 
possible, and he therefore seeks the solution of the problem in 
tlie former disposition of land and water and in altered hydro- 
graphic conditions. As to the supposition of Agardh, that it 
will probably appear by more scrupulous examination, that the 
number of species widely spread or at least common to the 
Atlantic and Pacific is rauch smaller than hitherto presumed, 
Kjellman is most disposed to assent to his opinion. However 
in the latest careful work ab out the fiora of the northwestern 
coast of America (49), the only part of the north-pacific coast- 
lines that can be said to be comparatively well known, 
Setchell and Gardner have, even if some old statements 
about the occurrence of atlantic species are cancelled, also 
identified some algae, formerly regarded as representative 
species, with atlantic ones, or at least only given them rank 
of varieties. Consequently the number of atlantic-arctic-pacific 
species has become as great as previously mentioned and also 
tfie group of atlantic-pacific species has sooner become augmented 
than diminished. 
In the following takle (VII) the latter algae are enumerated. 
I have here also inserted separate columns f'or the Bering Sea 
and for the northern part of the eäst coast of Asia, although 
nearly all species are stated only from the american side.
