On the basis of the floristic similarities examined by the present authors for the benthic species of the Chlorophyceae and the Phaeophyceae, the Japan Sea coasts may be divided into two phytogeographic regions : (1) from Kagoshima-ken (Cape Noma) to Tsugaru Strait and (2) from Tsugaru Strait to Hokkaido (Cape Nosappu). This result agrees well with OKAMURA's phytogeographical opinion. But the present study showed that the discontinuity of these two regions at Tsugaru Strait is not so strong. Being influenced with Tsushima warm current, these two regions have commonly temperate algal floras. From the view points of the phytogeographical indexes, I/H value and L/F value, the Noto Peninsula is considered to be situated in a warm temperate region of Japan Sea coasts. Further investigation will make it clear that this Peninsula has a warmer algal flora.
