is rendered evident by the following notes. Two packets of about 
20 species each were sent during 1905 from Wonsen, and, with the 
exception of two species, none of the plants hi the two packets 
were the same. In supplies from Fusm only three species were 
found which were included in the Wonsen list. Okamura'fl list 
above referred to is found to be again very different. The 
marked dissimilarity in these collections shows therefore that 
there is a considerable variety in species, and that before an 
adequate idea of the marine vegetation of the country as a whole 
can be formed, a much larger supply of material is necessary, not 
only from various localities, but collected at different seasons of the 
year. In some cases the material sent was insufficient for identifi- 
cation, and in not a few instances the generic names only could be 
given. The omission of these from the list, and also of certain 
critical species, will account for the number of names being 
somewhat smaller than might be expected. 
The algae received from Corea resemble, as one would expect, 
those of Japan — the only eastern country of which the marine flora 
is well known. Besides including some of the most interesting 
Japanese species, the packets sent contained several plain- which 
have not hitherto been recorded from Japan, and others which 
The recording of several critical species of which no authentic 
specimens exist in this country, and as to which further informa- 
tion is desirable, is for the present postponed.

The Corean specimens, like those known from Japan, resemble 
the Californian variety of Codium mucronatum rather than the 
Australian.
