or rarely simple; according to Sauvageau, who examined the type in Herb. Kut- 

 zing, the simple ramuli were more or less confined to adult parts. This is not the 

 case in my specimens from St. 16 and 27. But I cannot see any valid specific 

 character in this, and I still believe that my plants represent C. antarcticus. Is this 

 species really different from C. setaceusl I hardly think so. The latter would be 

 characterized by its longer, not branched ramuli, the former by the ramuli being a 

 little shorter and often forked. Both seem to differ from C. spongiosus and verti- 

 cillatus in the more slender branchlets and in the almost total absence of hairs, at 

 least on the sterile ones. 



W. Patagonia: Puerto Bueno, sublitoral on Mytilus, 1 — 3 m (St. 27, 3. 

 6. 08, sp.). S. Patagonia: Otway Water, Puerto Toro, 20 m, and drifted (St. 

 16, 18. 4. 08, sp.). 



Distribution: Patagonia, Fuegia, Falkl. 



C. spongiosus (Lightf.) Ag. — Fig. 18 f. 



Patagonia: Skyring Water, drifted near Punta Rocallosa (Apr. 08, sp.) — 

 I am unable to separate this from ordinary C. spongiosus. The earlier records of 

 this from the south were justly regarded as doubtful by Sauvageau. My specimens 

 are not quite so dense as C. spongiosus, but do not show the marked distant verti- 

 cils of C. verticillatus, which species agree in most respects. The ramuli in my plants 

 agree very well with the figures published by Sauvageau 1. c. p. 533, as do also 

 the fertile branchlets. On the other hand, the plants are rather unlike all the spe- 

 cimens referred to C. setaceus or antarcticus. The number of ramuli to a verticil is 

 10 to 12, thus much less than the average in C. spongiosus or verticillatus, which is 

 24 according to Sauvageau. But var. patentissimus Sauv. of the latter has 8 to 12. 

 Sauvageau says the summer ramuli in C. spongiosus are branched, the spring and 

 autumn ones often simple. My specimens were taken in April, i. e. in the autumn 

 and have branched ramuli.

Laminariaceae. 

 Phyllogigas Skottsb.

South Georgia: Cumberland Bay, Moraine Fiord, drifted (20. 4. 09); 

 Boiler Harbour, c. 5—10 m (St. 48, 49, 20. 4. 09); Bay of Isles, drifted (25. 4. 09). 

 — Unfortunately, the material is sterile, so I have nothing to add to my previous 

 notes in Ant. Meeresalg. I p. 63. The species was probably collected in South Geor- 

 gia as early as in 1882, for Laminaria saccharina var. angustata Reinsch, Meeresalg. 

 Siidg. p. 414 very likely ref ers to Phyllogigas.
