Notes on Marine Algoe. By E. A. L. Batters. 113 



32. Conferva MELAGONruM, {Wei. et Mohr.) — This plant is to 

 be found in deep pools near the Coves ; its long stiff filaments 

 which stand straight up in the water like pieces of wire, render 

 this species unmistakeable ; it is rather rare. 



33. Conferva ^rea, {Billw. ) — Eare. This species is some- 

 times to he found in shallow sandy pools near the *' Grreenses." 



34. Calothrix scopuLORrM, {Ag.) — Common on the coast near 

 Berwick. This plant forms a dark green film on rocks near 

 high water mark rendering them very slippery. 



35. Calothrix fasciculata, {Ag.)—A. taller, handsomer, and 

 much rarer species than the last ; it is not uncommon near 

 " Sharper Head." 



In addition to the preceding species, the whole of which may 

 be found described and figured in any good manual of the British 

 Algae, the following species, hitherto unrecorded on our coasts, 

 have been found at Berwick, and my very best thanks are due 

 to Mr Holmes, F.L.S., for his kindness in naming my specimens 

 and furnishing me with much valuable information concerning 

 them. 



36. Phyllitis fascia, — Very rare. This species is very like 

 Chorda lomentaria, only flat ; it is to be found a little to the north- 

 ward of the Needle-eye ; it was first found on our coasts by Mr 

 Holmes at Elie in Fifeshire, and has, I believe, been found no- 

 where else in Britain except at the station above recorded. 



37. Phloespora tortilis. — This plant looks like a very curly 

 variety of JDictyosiphon fosniculaceus ; it has been recorded from 

 two or three Scotch and one Durham localities. 



38. Melobesia laminari^. — Not uncommon. Parasitical on 

 the stems of Laminaria digitata on which it forms a thin crust ; it 

 may be known by its very depressed cystocarps scarcely visible 

 above the surface of the pond. 



39. NiTOPHYLLTJM REPTANS. — Pare. Parasitical on the stems 

 of Laminwria digitata, and attached to them by innumerable little 

 rootlets ; it was first noticed in this country at Sidmouth by Mr 

 Holmes. Berwick, I believe, is the only other locality where it 

 has been found in Britain. 



40. Thamnidion intermedium. — Very rare. A species which 

 at first sight might be taken for CallitJiamnion Turneri, but the 

 stem is forked, and the fruit corymbose and borne on the lateral 

 branches. 



41. Dasya Gibbesii. — Very rare indeed. Not unlike D.
