 Jiarv report on the Fucaeeoiis algte of Japan in the Tokyo 

 Botanical Magazine." In that report the present writer asked 

 for the loan of specimens to enable liim to secure as complete 

 data as [)ossible in discussing the distribution of the family on 

 our coasts, and several botanists who had specimens in their 

 herbaria kindly forwarded them for the writer's examination. 

 Prof. K. MiYABE who had for twenty years carefully studied 

 the marine flora of Hokkaido placed all his collection, together 

 with that of the Fisheries Department of the Hokkaido Local 

 Government, at the writer's disposal. These extensive collections 

 have thrown much light upon the northern species, as may be 

 seen under the proper headings. The present writer may declare 

 with assurance that few species of the family Micacece, if any, 

 are likely to be found in Hokkaido to be added to the present 

 work. Only by the unequalled kindness of Prof. Miyabe was 

 such a result possible. A species found in his collection, 

 undoubtedly new to science, is described in this paper under the 

 name Sargaasum Miyabei in recognition of his generosity. 



Greatly to the regret of the writer it is necessary to say 

 that the coast of Loochoo as well as that of the southern parts 

 of the Kiushiu Islands have not been thoroughly botanized. The 

 s})ecimens from those localities were few in number and often 

 fragmentary. Many of them belonged to the "duplicate-leaved" 

 form, the most (juestionable members of Saygasmtn. Some of 

 them were sent to Major Theo. Reinbold for his opinion on 

 them ; and he was so kind as to take the trouble to compare 

 them with the authentic specimens and to give invaluable advice
