188 CRYPTOGAMIA ANTARCTICA. ] Fuegia, the 
Scotland, also on the east coast of North America, the West Indies, and on the west coast of South America. It 
is singular that Kerguelen’s Land should be its only hitherto recorded locality in the Southern Hemisphere. 
3. Conrerva Sandvicensis, Ag.; Syst. Alg. p. 92. (Tas, CXCIL. Fig. IT.) 
Has. Berkeley Sound, Falkland Islands; in pools of fresh water, and hanging from wet rocks. 
Massa pedalis et ultra, mollissima, pallide sed leete viridis, e filis tenuissimis arachnoideis densissime fasti- 
giatis constans. Fila hyalina, flaceidissima, simplicissima, vix intertexta, aciem oculorum fugientia. Artieuli diametro 
duplo longiores, subvitrei ; sacculo endochromatis interno medio constricto, leete virente, pellucido. 
Our specimens entirely agree with Agardh’s description of a plant brought from the Sandwich Islands = 
M. Gaudichaud. 
Puare CXCII. Fig. 11, plant of the natural size; 2, portion of a thread; 3 & 4, other portions of ditto : 
— both very highly magnified. 
4. CoxrERvA angulata, Hook. fil. et Harv. ; fluitans reptansve, filis simplicibus tenuissimis brevibus 
strictiusculis hic illic incrassatis angulatisque angulis radiculo ramulove abnormali auctis, articulis diametro 
3-5-plo longioribus coloratis, endochromate siccitate contracto. Nobis in Lond. Journ. Bot. vol. iv. p. 295. 
(Tas. CXCI. Fig. II.) 
Haz. Christmas Harbour, Kerguelen's Land ; common in streams, pools, and lakes of fresh water. 
Fila intertexta, tenuissime capillacea, in massam pallide virescentem subnitentem conferta. ۵ siccitate 
contracti, æquales, nune medio incrassati, nucleati, rarissime ramum emittentes, seepissime radicula parva uniarti- 
culata aucti, nune geniculatim ćurvati. 
Allied to the British C. bombycina, but readily distinguishable by its greater rigidity, angular flexures, radicles 
and different incrassations, which do not appear to us of the same character as those of Mr. Hassall's genus * Vesi- 
culifera’ The filaments are sometimes ramified, though very rarely, and perhaps only at the very base: the branch 
is always at right angles to the filament.

branch ; 4, ditto with rootlets ?; 5, ditto with swollen joint :—all very highly magnified. 
5. Conrerva ambigua, Hook. fil. et Harv. ; filis basi intertextis adnatis? capillaribus rigidulis nigro- 
virescentibus longe fluctuantibus simplicibus hic illic spurie? ramosis radicantibus, nunc processubus 
lateralibus anastomosantibus auctis diametro 2-3-plo longioribus opacis sacculo endochromatis repletis. 
Nobis in Lond. Journ. Bot. vol. iv. p. 295. (Tas. CXCI. Fig. L.) 
Haz. Christmas Harbour, Kerguelen's Land ; in the sea. : 
Fila 4—5 unc. longa, basi in stratum densum intertexta, deinde libera, elongata, massam crinitam efficientia. 
Puare OXCI. Fig. L—1, plant of the natural size; 2, filament from ditto :—magnified. 
6. Conrerva quadratula, Hook. fil. et Harv.; pusilla, filis tenuibus pallide viridibus flexuosis intricatis 
cylindraceis, articulis quadratis siccitate endochromate collapso notatis. (Tas. CXCI. Fig. IV.) 
Has. Christmas Harbour, Kerguelen's Land; in pools and streams of fresh water; very common. 
Fila simplicissima, sub 4 unc. longa, in strato dilute viridia, implicata, crispata, diametro C. floccose duplo 
triplove superantia. Articuli longitudine diametrum «equantes, cylindracei, ad nodos non constricti, pellucidi, 
endochromate plerumque in massam linearem viridem collapso medio notati. 
Puare CXCI. Fig. IV.—1, plant of the natural size; 2, thread from ditto ; 3, portion of ditto :—both very 
highly magnified.
