A British Marine Flora is being compiled, but no date 

 for its appearance has, I have been kindly informed, as 

 yet been fixed by its author. 



The works by Murray and Hauck quoted above may be 

 of some help, especially the former, although it treats of 

 foreign as well as British marine algae. It contains a 

 short list of books and atlases of algological interest. 



Vol. I., part 2, of Engler and Prantl's " Die Naturlicken 

 Pnanzenfamilien," which treats of the algae, is a very 

 useful book to consult. By the aid of this the beginner 

 may often be able to determine the genera.
