Haz. Hermite Island, Cape Horn ; on stones near high-water mark. 
Pusilla, dense fastigiata.. Frondes 4 unc. longee, e basi in ramos plurimos primarios divisee, rubro-purpurez. 
Caulis brevissimus. Rami elongati, curvati, apicibus arcte incurvis, ramulis simplicibus multifidisve ornati :—chartee 
laxe adheeret. 
Possibly only a variety of the preceding ; from which, however, it differs conspicuously in the very abbreviated 
stem, the consequently longer, more divided branches and the duller colour. 
8. STICTOSIPHONIA vaga, Hook. fil. et Harv.; caulibus flexuosis vage dichotome ramosis, ramis paucis 
nudis simplicibus filiformibus subcapillaribus arcuatis medio incrassatis apicibus incurvis, ramulis nullis, 
axillis patentibus, stictis minutis multiseriatis, stichidiis longissime pedunculatis lanceolatis acutis. Bos- 
trychia vaga, nobis in Lond. Journ. Bot. vol. iv. p. 270. (Tas. CLXXXVI. Fig. E) 
Has. Christmas Harbour, Kerguelen's Land; on rocks and stones above high-water mark, and in 
damp places at a considerable distance from the sea; abundant. 
Dense ceespitosa, filis intertextis quasi crinita. Prondes 4—1 une. longs, flexuose, irregulariter ramosze, capil- 
lares. Sticte parve, 6-8-seriate. Substantia rigida. Color luride purpureus :—chartee laxe adheeret. 
A remarkably distinct little species, of very simple structure. It is abundant in Kerguelen’s Land, sometimes 
inhabiting places some hundreds of feet above the sea, but probably always within reach of the spray.

1. LAURENOIA pinnatifida, Lamx. Var. y. angustata, Hook. ; Fl. Antarct. Pt. 1. p. 184. 
Has. Berkeley Sound, Falkland Islands ; abundant on the beach. 
One of the most widely dispersed of the Alga, inhabiting the shores of Europe from Norway to the Medi- 
terranean ; the Canary Islands; west coast of Africa, and Cape of Good Hope; the Peninsula of India ; Australia 
and New Zealand; the Pacific Islands, and both coasts of North and South America. This very extended range 
has, however, its limits ; the plant is neither found so far north as Iceland in the Arctic Sea, nor in the south is it 
known to inhabit Cape Horn or Kerguelen’s Land.

Has. Christmas Harbour, Kerguelen’s Land; common. 
Magnificent specimens of this noble Alga were collected by the Antarctic Expedition, though only in Kerguelen’s 
Land. The previously assigned habitat for the species is New Holland or Tasmania; but we have seen no other 
specimens than Mr. Fraser’s original one, labelled as from that quarter of the world. It therefore appears to us 
probable, that . the specimen sent by Mr. Fraser, may have been collected in Mc’Quarrie’s Island; whence other 
Antarctic plants were brought to that gentleman in Sydney, some of which have since found their way into our 
Herbaria as of Australian origin.
