I met with this species at a single pl ace only. It grew 

 in a small and shallow rock-pool (or chiefly in the margin 

 of. the pool) at or perhaps a little above high-water mark 

 in a rather exposed locality, and jointly with Calothrix sco- 

 pulorum. The Finmarkian specimens belong to the foini 

 aduUior. Cp
