about equal to the beautiful figure, PI. ii. in ' Phycologia 

 Britannica.' But at times in Ayrshire and in the island of 

 Cumbrae the frond is remarkably narrow, not above half a

 Rev. Gilbert Laing from Orkney, and I have one magnifi-

 of which the frond is so large that it might be mistaken for 

 a young specimen of Delesseria sanguinea. 



6. Delesseria ruscifolia, Lamour. (Plate XIII. fig. 49, 

 plant with tubercles on the leaves and leaflets, natural size.)

 digitata, and on other Algse. Annual. Summer and 

 autumn. It is rare in Scotland. It has twice been pro- 

 cured, floating, in fine condition, by Miss M'Leish, in the 

 sea at Saltcoats. Miss White, Isle of Portland. By far the
