G2 SYNOPSIS OF BEITISn SEAWEEDS. 



Beparated by spaces bare of ramuli. In all other respects 

 the two plants closely resemble each other, and as they are 

 frequently found intermixed on the Bame frond of Chorda 

 lornentarta, I formerly regarded the present as merely a 

 <>f M. clavcrformis. 

 M.filtformis is much the most abundant species, and is 

 indeed very generally to be found clothing the Chorda, when 

 the latter grows in small shallow pools, exposed to Btrong 

 sunlight. In such localities almost every frond of Chorda 

 lomentaria is converted into a soft, cylindrical brush, from 

 the multitudes of these little parasites, clothed with, their 

 gelatinous, transparent hairs, which, while the plant re- 

 mains in the water, stand out on every side, keeping each 

 little filament free of its neighbour. AVhen drawn into the 

 air, the whole falls together in a gelatinous mass.
