July, 1916.] YEN DO.- NOTES ON ALGjE NEW TO JAPAN, V. 257 



Ibuiid aL Lund. This form is not represented on oiu" coast so 

 lar as our material show. 



Are not Apopholoea Lyalii II. ct 11. and Carpococcus pcr- 

 phoratus }. Ac. comparable with the [)resent species? I have 

 not examined tlie structures of these plants. In the external 

 api^jcarances they rcseml)le so closely with A. concinna that I 

 can not restrain mysclt" in j^uttins^' forth the question. 



Locality. Bdshu Prov. (F. Sugiyama); Sagami Prov. (I); Ise 

 Prov. (K. Akatsuka). 



Distribution. Sandwich Islands; Peru. 



Callymenia reniformis J. Ag. var. cuneata J. Ag. 



Epicris, p. 22L— De Toni: Syll. Alg., IV, p. 297. 



Callrmenia reniformis has been reported by Martens," uiidcr 

 Eubynienia reniformis KuTZ. to have been collected in Yoko- 

 hama, The specimen now kept in the Herbarium of the 

 Botanical Museum of Berlin ajjpears to me to be Micrococla 

 chilensis Okam. Holmes also mentions the same species in his 

 list of Japanese algae. Unfortunately, I could not find any 

 Japanese specimen of it in the Herbarium of the University of 

 Birmingham, where, as I was told from him, all his eolllection of 

 algae was to be found. None of Japanese collectors has ever 

 found it on our coast and so the above mentioned informations 

 were discredited or doubted by me. 



In northern parts of Japan, how-ever, there is a form of 

 Callymenia which can be no other\yise than to identify with 

 Callymenia reniformis var. cuneata J. Ag. It varies in Its 

 shape of frond but not as to be referred to the typical form of 

 the species. 



Locality. Rebun Island (!); Otaiu Bay (!); Hakodate (I); 

 Awomori (N. Takahasui) ; Muroran (N. Takaiiasiii) ; Hidaka 

 Prov. (!). 



Distribution. Europe.
