Falkland Islands: West Falkl., Halfway Cove, on Macrocystis (23. 4. 

 07, gt.). — I can see now that the gametangia described in 1907 were unripe. The 

 ripe ones are narrow conical, sessile or pedicillate, sometimes apical in a short branch,

120 — 190x24 — 36 \i.. The main filaments attain 80 ^ across. The chromatophores 

 are narrow, bandlike and branched and several in each cell. This species should be 

 compared with E. fasciculatus, from which, however, it seems to differ considerably. 

 Distribution: Falkl.
