southern part of Japan, but they nre not included here, being- left for 

 future publication. 



During the past fifty years, the Marine Algae of Japan have 

 attracted the notice of several European botanists, and the literature 

 relating to them is not inconsiderable. Yet the calcareous algae 

 seem to have been neglected by these collectors and investigators, 

 only a few species being mentioned in their writings. 



Georg von Martens enumerated^) 6 species of Corallinae which 

 were collected on the coast of Japan and its vicinity. Afterwards a 

 few more species were reported from Formosa collected by Warburg 

 and determined by Heydrich^). De Toni 3), Wildeman*), and others 

 compiled a list of Algae reported from Japan and Eastern Asia, 

 in which 11 species of Corallinae are assigned to Japan. 



Among these 11 species, some are limited to Formosa and 

 Loochoo, upon which I do not touch at this time, and of others it 

 has been impossible for me to verify the existence. Cheilosporum 

 (Arthrocardia) frondescens, Corallina(?) filicula, and Corallina 

 officinalis v. mediterranea, reported by Martens to have been collected 

 at Yokohama, are especially doubtful to me. When we set these 

 members aside, we have left only two or three sj)ecics which I feel 

 justified ill incorporating in the present studies. 



The figures in the accompanying plates have been made from 

 sections of the di-ied materials, if not otherwise stated. The author 

 found Pereny's fiuid answers best for the decalcification of the 

 material. In the case of more delicate plants acetic-sublimate or 

 Flemming's fiuid may also be used. For staining he preferred
