dantly found on the rocks near the low water mark on the coast 

 of the North Kuriles. It was already found on the north-west 

 coast of North America as far west as the Aleutian Islands. It 

 is interesting to find this species within our boundary.

I mention here another species of Coilodesme to be added to 

 the algal flora of Japan. It is found growing attached to the

 than C. hulligera and may be found on the coast of Hokkaido 

 proper.

In the Illustr. of the Mar. Alg. of Japan, Vol. I. No. 2, Oka-

 sure that Phyllitis Fascia Kutz. is quite common in the northern 

 Japan. On the coast of Hokkaido the occurrence of Endara-
