This seems to be a typical member of the Dictyosiphonacese. My figures ex- 

 hibit the mode of grovvth and the distinct top-cell. There is of course much difference 

 between S. Jiirsutus and the type of the genus, S. australis, but if S. jasciculatus is 

 included in this genus, I can see no other possibility than to bring also the new spe- 

 cies there. On the other hand, it differs from the last mentioned in being epiphytic, 

 bl the much smaller size, the shape of the branches, the thin wall of the thallus 

 cavity and the hairs.

 only few specimens seen (St. 1, 1. 11. 07). — Determined with the assistance of 

 Prof. Kuckuck.

Falkland Islands: Port Stanley on Godium, drifted (1. 11. 07, with sp. 

 and gt. on the same specimens); Cape Pembroke, common, mostly on Codium (St. 

 3, 7. 11.07, sp. & gt. on different indiv.); Port Louis (St. 11, 7. 2. 08, gt.). — 

 Kutzing^ figure leaves no doubt of the identity of his Phycolapathum lanceolatum. 



In one instance gametangia and sporangia were found on the same individuals, 

 but otherwise they belong to different plants. I ha ve thought it convenient to publish 

 some new and better figures of this interesting and characteristic subantarctic alga. 

 Several very young plants were collected in November, showing the mode of growth 

 (fig. 14 i-k).
