Alg., I.e.) 



I have reported in this Notes the occurrence of Ralfsia 

 deusta J. Ag. in the colder seas of Japan. Another species of 

 Ralfsia was found at Hakodate on mussel shells and stones in 

 the upper sublitoral region. Although no sporangia could be 

 found in the specimens I have a least hesitation in identifying 

 them with the present species. The crusts on mussel shells were 

 thinner in substance and had smoother surfaces than those on 

 stones. 



Locality. Hakodate (!). 



Distribution. Atlantic coast of Europe; Mediterranean Sea ; 

 Atlantic coast of North America ; Alaska ; Whidbey Island, 

 Washington; California.
