South Georgia: probably common in the sublitoral region. Cumberland 

 Bay, Boiler Harbour, 5—10 m (St, 48, 49, 20. 4. 09, ?); Moraine Fiord, drifted (18. 4. 

 09); Strömnaes Harbour, 8 m, stones (St. 50, 24. 4. 09, ©); Bay of Tsles, Rosita Harbour, 

 8 m, gravel (St. 52, 25. 4. 09, ?, ©). 



Distribution: N. Zeal., S. Georgia, 



Curdiea Harv. 



C. reniformis Skottsb. ia Kylin & Skottsb. p. 18 f. 9. 



South Georgia: Bay of Isles, Rosita Harbour, 8 m, rocks and gravel (St. 

 52, 25.4.09,?). 



The cystocarps of this species and of the closely related C. Racovitzae Hariot 

 are scattered över the frond and not at all confined to the margin as is the case in all 

 other Curdieae (I have gone through the rich material in Herb. Agardh), where they 

 are also much more protruding. According to the customary subdivision of the subfam. 

 Melanthalieae (vide De Toni, Sylloge 4: 2 p. 412), the Antarctic species cannot belong 

 to that genus nor to the same group, but come near Sarcodia; however, they have not 

 the anatomical structure of this, but of Curdiea. 



In the fronds Entocolax Rhodymeniae Reinsch, Meeresalg. Siidgeorg. p. 399, T. 

 XV, f. 7 — 8, is plentiful. I think the male conceptacles of C. Racovitzae, described by 

 Gain, Fl. Algol, p, 61, f. 54: — 59 are perithecia of this same Entocolax. 



Distribution: S. Georgia, 



Gracilaria Grev. 



G. aggregata Hook. Fil. et Harv. Lond. Journ. Bot, 4 (1845) p. 261, Fl. Ant. II p. 478. 

 Cotton, Crypt, Falkl. p. 180. 



Falkland Islands: Cape Pembroke, on small stones in tide-pools (St. 

 3 b, 7. 11.07). 



There has been some uncertainty about this, but I believe Cotton has removed 

 all doubts as to its position. He refers Gymnogongrus implicatus of Hohenacker, Exs. 

 no. 181 to this with some doubt; I have examined the specimen in the Upsala set, and 

 I find that Cotton' s identification is quite correct. 



On some of my specimens there are small scutate discs suggesting some parasitic 

 species, but they are only young horizontal thalli of the Gracilaria, small erect fronds 

 arising from some of them. 



Distribution: Falkl. 



G. pulvinata nov. spec. — Fig. 3 a — c. 



Syn: Dumontia fastigiata Bory var. minor, Hohenacker Exs. no. 282 (Port Stan- 

 ley); Chaetangium fastigiatum v. minor J. Ag. Hariot Miss. Sci. p. 96.
