Marine Algce of Bemvick-on-Tweed. 247 



Hnb. Epiphytic on various small Algae in shallow pools between tide- 

 marks, also on rocks. -Tan. — May. Not common. Berwick 

 Bay. Coves, Holy Island. 



The fronds of this pretty spring species are at first saccate, 

 and very much inflated, resembling a "Florence-flask in 

 miniature," but when old, they are split to the base into irregular 

 segments. The fronds, which are of a beautiful yellowish green 

 colour, are very thin and delicate, and adhere firmly to paper in 

 drying. As Le Jolis has pointed out,* the Enteromorpha 

 Cornucopia of Phycologia Britannica is in all probability only a 

 form of this species. I have gathered at Holy Island and else- 

 where along the coast, specimens exactly agreeing with Harvey's 

 figure and description of Enteromorpha Cornucopias which should 

 undoubtedly be referred to Monostroma Grevillei.
