I have twice received the specimens of the present species 

 for determination from southern Japan. It was a question to 

 me if, as Dickie reported to have collected, another species C. 

 cribrosa Harv. really occurs on our coast. In the Herbarium 

 of Kew Gardens I was fortunate enough to have the opportu- 

 nity of seeing the specimen collected by Moseley in the Chal- 

 lenger Expedition upon which Dickie's report was based. It is 

 a small fragment but the perforations seem to show the charac- 

 ters of C. perforata J. Ag. and not of C. cribrosa Harv. 



The figures illustrated by Okamura under C cribrosa Harv. 

 in his Icones Jap. Alg. I.e., are excellently showing all the char- 

 acters of the present species.
