chromatophores comparatively shorter and broader in a living state. A basal disc 

 is very conspicuous, not very unlike that of a Myrionema, and bearing basal game- 

 tangia. On the other hand, there is in the Subantarctic a real E. confervoides, which 

 Prof. Kuckuck declared identical with European plants. E. exiguus is perhaps similar 

 to E. pygmceus Aresch. = confervoides f. pygmcea Kjellm. 



Fuegia: Orange Bay, on Lessonia (St. 45, 11. 3. 09, gt.). Falkland Is- 

 lands: Port William, on Macrocystis (St. 2, 7. 11. 07, gt.). South Georgia: 

 Bay of Isles, on Desmarestia ligulata (St. 52, 25. 4. 09, gt.). 



Distribution: Fuegia, Falkl., S. Georgia. 



E. confervoides (Roth) Le Jol. 



Patagonia: Canal Gajardo, on rocks (St. 21 b, 27. 4. 08, gt.). Fuegia: 

 Slogget Bay (St. 47, 16. 3. 09, gt.). Falkland Islands: Stanley Harbour, on 

 other algae in the litoral region (St. 1, 3. 11. 07, gt.); Cape Pembroke, common in 

 tide-pools on Corallina (St. 3, 7—8. 11. 07, sp. & gt. on different individuals); West 

 Falkl., Halfway Cove, sublit. 5 m (St. 5, 25. 11. 07, gt.); Westpoint Isl., on Macro- 

 cystis (St. 8, 6. 12. 07, gt.). South Georgia: Boiler Harbour, on Desmarestia 

 Harveyana (St. 48, 20. 4. 09, gt.). 



Distribution: N. Atl. and Pacif. Oceans, circumpolar subantarctic. 



E. siliculosus (DjLLW.) LYNGB. 



Patagonia: Skyring Water, Rucas Bay in large masses at 1 dm depth 

 (St. 19 b, 25. 4. 08, gt.). Fuegia: Admiralty Inlet, on Adenocystis (St. 13, 25.3. 

 08, gt.). Falkland Islands, Cape Pembroke, with the former (St. 3, 7. 11. 



07, gt.); Westpoint Island, tidal basins, on Ballia (St. 8, 6. 12. 07, gt.). 



Distribution: Probably the same as of E. confervoides. 



E. Constanciae HäRIOT. 



West Patagonia: Puerto Bueno, sublitoral on other algae, 1 — 3 m (St. 

 27, 3. 6. 08, gt.). Falkland Islands: Cape Pembroke, upper litoral with 

 Bostrychia (St. 3, 7. 1. 08, gt.); Westpoint Isl., in basins on Floridese (St. 8, 5. 12. 07, 

 gt.). — The specimens from St. 27 correspond very well to Hariot's description and 

 figure (Miss. sci. Cap Horn, Pl. 3), but the gametangia sometimes are as much as 

 100 1*, long. There are numerous band-like chromatophores in each cell, the younger 

 ones being short, almost disc-shaped as in the figure quoted. 



Distribution: Subant. Amer., Falkl., S. Georgia, Kerg. 



E. penicillatus Ag. 



Patagonia: Canal Fitzroy, Los Amigos, on drifted Leaihesia (St. 17 b, 19. 

 4. 08, gt.); Skyring Water, Puerto Altamirano, on stones, 1—2 dm (St. 18, 22. 4. 



08, gt.). 



Distribution: Aret. & Atlant., Baltic, Subantarct. Amer.
