southern limits. Of course by no means 

 all the important species can be men- 

 tioned in this brief account. Those 

 that I have named are among the most 

 notable, and will give an idea of the 

 algal facies. That the subarctic flora 

 is dependent upon the influence of 

 the eastern branch of the Behring cur- 

 rent is capable of clear demonstation.

 southern end of Kiushu island. 



In this region the district from Kink-

 forms. This is as would be expected 

 from the distribution of the current. 

 A poor specimen of Chordaria abietina 

 has been picked up at Cape Inuboi,
