Some New Algæ from Japan.

.r^mong the algal specimens in my possession, mainly col- 

 lected by myself in the northern parts of Japan, there are a 

 number of forms which are interesting in various points. Accounts 

 of some of them have been already published, but there still 

 remain scores of them for future description. My recent visits to 

 the Herbarium of the Academy of Science in St. Petersburg, and 

 to that of the Botanical Museum in Upsala, removed sundry 

 doubts relating to many of them. Four of them are mentioned 

 in the following pages, in the hope that they may be of some 

 interest to the reader. 



The present paper has been completed in the Botanical 

 Museum of Kristiania. Prof. N. Wille, the director of the 

 Museum, was so kind as to allow me the privilege of the free 

 use of his laboratory as well as his own collection of literature. 

 I wish here to express my sincerest thanks to him for his 

 kindness.
