 part of the sublitoral regions, descending to a depth of a- 

 bout 4 fathoms; and £ hystrix sublitoral, on a depth of 2 

 8 fathoms. Specimens with zoospores have been coUectedin

This species approaches on the one side to S, arda (f. 

 puhinata) and on the other side to S. atrovirens. Cp. Wittr. 

 et Nordst. Alg. exsicc. Ni\ 616. But it is distinguished 

 from both by essential characteristics. 



The plant lives in rock-pools in the upper part of the 

 litoral region at exposed places. I do not know when it 

 develops its reproductive organs. Specimens collected in 

 July were sterile. 



Bistrihution: Found at Kiberg and Pasvig, local but 



pretty plentiful.
