SEA WEEDS. 309 
Mesogloea vermiculata, Le Jol. 
Petit Bot. Cobo. Fermain. Bordeaux. 
Liebmannia Leveillei, J. Ag. 
I gathered a specimen in a rockpool off Bordeaux in the autumn 
of 1894, mistaking it for a large form of MJesogloea vermiculata. On 
learning that this was its first discovery in British waters, I searched 
carefully on several occasions, but failed to find any more of it.
