The specimen has been collected at Hakodate many yeai-s 

 ago. It seemed to belong to the present species but at the 

 same time referrable to E. coarcta Kjellm. Having had no 

 less doubts on the distinction between the two species, I left it 

 for future comparison. Actual examination on Kjellm ax's 

 originals at Upsala, I made it sure that my specimen was 

 identical with Kjellman's and that they were nothing but the 

 present species. 



The measurements given bj- Kjellman for the cells and the 

 thickness of frond of his species are slightly larger than in the 

 European forms of E. micrococca, but these are too trifle and 

 rather unfixed characters to claim an independent specific rank 

 for the plant. Kjellman 1 ' remarks :*"'" Sa vidt jeg forstar, ar
