discernible. Berwick Bay and all along the coast northwards. 

 Common. 



14. Sphacelaria ccespitula. Lyngl. Hydr. p. 1 05 t., 32, fig. A. 



Very minute tufts of fine filaments, growing on the roots of 

 Laminaria digitata. Filaments very slender. Branches irreg- 

 ular often secund, few. Joints about as long as broad. Colour 

 a light brown. 



Berwick Bay. Eare. 



There is a small Sphacelaria which grows in shallow sandy 

 pools a little to the north of Sharper head. It forms small tufts 

 which appear above the sand like fine wire. It appears to be 

 S. racemosa but as I have not found any fruit I cannot speak with 

 certainty. 



14. Cruoria adherens. J. G. Ag. Sp. Alg., vol. II., p. 491. 

 Frond forming a thin, smooth, fleshy crust on the stems of 

 Laminaria digitata. Frond at first circular afterwards irregular 

 in shape, half an inch to two inches in diameter. The crust is 

 composed of erect, or once or twice dichotomous, jointed fila- 

 ments set in gelatine, all of one length so as to form a smooth 

 surface,] oints nearly as long as broad, colour a dark reddish-purple . 

 Substance tough, but still fleshy-feeling, horny when dry. I 

 have seen no fructification except the terminal pyriform green 

 spore surrounded by a wide gelatinous limbus described by 

 Harvey in the Natural History Eeview vol. II. (1867), p. 203 

 and pi. 13, c. fig 1. 



Berwick Bay, common. 



16. Melohesia Lenormandi, Aresch. (Lithophyllum Lenormandi, 

 Hosanoff.) 



Frond forming a thin chalky crust on rocks, the under surface 

 closely adherent, the upper smooth. Fronds suborbicular at 

 first, afterwards overlapping one another and irregular in outline, 

 slightly zonate, margins crenate, lobed, tetraspores four-parted 

 contained in hemispherical conceptacles very much flattened on 

 the top, orifices of the conceptacles numerous. 



Berwick Bay &c., common. 



17. Melohesia corallince. Crn., Liste des Alg. mar. 1. c, Fl. d. 

 Finist. p. 160. 



Fronds small, one or two lines in diameter, pale-lilac or mauve, 

 thick, slightly convex, obovoid or deltoid, confluent, sometimes 

 lobed, conceptacles numerous not much raised above the surface 

 of the frond, spores divided into two.
