Okamura, K., On the distribution of Co^^mw. (Bot. Mag. Tokj'^o. 

 XXVIII. 325. p. (1)— (5). 1914. in Japanese.) 



After having enumerated 32 species of Codium hitherto known 

 from several localities in the world at large, the author states that 

 of 32 species 12 are found in this country and of the 12 sp., 7 are 

 indigenous to Japan. It may be said that Codium species are 

 mainly found in the Pacific and Atlantic Oceans. Okamura. 



Okamura, K., On the marine Algae ofChosen. (Rep. Imp. 

 Bur. Fish. Sei. Invest. II. p. 17—30. PI. VI. 1913.) 



The author enumerates 102 species (8 Chlor ophyceae, 30 Phaeo- 

 phyceae, 63 Rhodophyceae and one Cyanophycea) of Chosen mostly 

 from the eastern and southern coast, putting together the materials 

 collected by him and other seven Japanese gcntlemen as well as 

 Cotton's from Fusan and Gensan (Cotton A.D., Marine Algae 

 from Corea in Kew Bull., 1906, p. 366—373). After having mentioned 

 table of distribution the author states that the general feature of 

 marine algae on the greater part of the coast north from Fusan, 

 as well as from Fusan westward to Kunsan, is the same as that 

 of the Pacific coast of the Mainisland of Japan and the coast 

 of the Japan Sea; and of 102 species enumerated some ten are 

 subarctic algae and the rest are the temperate ones. He also states 

 that he shall risk the Suggestion, though it is rather hasty to draw 

 any conclusion from such insufficient material, that Kanko wan 

 (Zarina Bay), at the north corner of which Seikoshin is situa- 

 ted, is the provisional point where the greater part of the northern 

 algae disappears. A new species of Ecklonia with specific name sto- 

 lonifera Okam n. sp. is illustrated in plate. Okamura. 



Okamura, K., Undaria and its Species. (Bot. Mag. Tokyo. XXIX. 

 346. p. 266—278. PL XI. 1915.) 



The three related species, Undaria pinnatifida Sur., Hirome 

 Undarioides Yendo and Laminaria Peterseniana Kjellm. have been 

 long considered to have the following many points in common 

 viz.: presence of cryptostomata, characteristic, dot-like mucilagi- 

 nous glands and paraphyses capped with mucilaginous mass and
