ceramidiis pusillis ovatis breve pedicellatis. Nobis in Lond. Journ. Bot. vol. iv. p. 265. (Tas. CLXXXII. 
Fig IIT.) 
Has. Hermite Island, Cape Horn; very rare. 
Fil. 3-4 unc. longa, capillaria, flaccida, tenacia sed non fragilia, dense ceespitosa, basi irregulariter dicho- 
tome ramosa, ramis omnibus diametro sequalibus. Ceramidia minima, lateralia, elliptico-urceolata. Color luride ruber. 
Prate CLXXXIT. Fig. 111.—1, portion of branch; 2, ditto with ceramidium :—both highly magnified. 
7. PoLYsSIPHONIA abscissa, Hook. fil. et Harv. ; coccinea, frondibus circumscriptione ovatis tenuibus 
membranaceo-gelatinosis flaccidis tenacibus oligosiphoniis, caule primario parce diviso flexuoso ramos 
secundarios alternos multifidos circumscriptione obovatos emittente, ramis filiformibus minoribus alternis 
subdichotome divisis, ramulis fastigiatis (quasi abscissis) fibrilliferis, articulis ramorum diametro quadruplo 
v. sextuplo, ramulorum duplo triplove longioribus bistriatis, ceramidiis pusillis ovatis breviter pedicellatis, 
Nobis in Lond. Journ. Bot. vol. iv. p. 266. (Tas. CLXXXIII. Fig. IT.) 
Has. Hermite Island, Cape Horn; dredged up in about six fathom water. 
Frons seu ramus primarius 3-4 unc. longus, filiformis v. capillaceus, flexuosus, alterne ramosus, ramis grada- 
tim brevioribus, hinc circumscriptio frondis totius ovata evadit. Rami inferne nudiusculi, superne fastigiatim ramu- 
losi; ramulis ultimis tenuissimis, confertis. Caulis tubuli sub quatuor. Color roseus v. coccineus. 
A beautiful species, of which the only specimens were procured with the dredge in St. Martin's Cove. 
The fastigiate branching of the ramuli and the colour are, of themselves, sufficient to distinguish this from the 
P. microcarpa, to which it is most nearly related. The principal stem is very conspicuous though slender, and 
the branching regular and tolerably uniform. 
Prats CLXXXIII. Fig. IL.—1, plant of the natural size; 2, branch and ramuli; 3, portion of ramulus ; 
4, portion of ramus; 5, ditto, with ceramidium :—all highly magnified. 
8. PoLysIpHoNIA flabelliformis, Hook. fil et Harv.; pusilla, setacea, badia, rigidula, fronde brevi basi 
simplici stipitiformi apice flabellatim ramosa, ramis irregulariter dichotomis multifidis apice subfastigiatis, 
ramulis ultimis erectis longe nudis, axillis angustis, articulis multistriatis inferioribus diametro multiplo 
superioribus sesquilongioribus. Nobis im Lond. Journ. Bot. vol. iv. p. 266. (Tas. CLXXXIII. Fig. I.) 
Haz. Crozet Islands; on Macrocystis pyrifera. 
Frons uncialis, solitaria, rigida, crassitudine setze porcine, inferne simplex, superne distiche flabellatim ramosa, 
crassiuscula, circumscriptione orbiculari. Rami multifidi, irregulariter dichotomi, fastigiati, ramulis erectis. Articuli 
rami valde elongati, striis numerosis notati. Color badius, vix rufescens :—chartee vix adhseret. 
Only one specimen of this very distinct species was procured, from a piece of Macrocystis floating off the 
Crozet's Islands, of which group the present, the Callithamnion Ptilota, nob., and Ballia Brunonis, are the only 
known vegetable productions.

Var. 8. Davisii ; robustior, caule primario regulariter ramoso, ramis erecto-patentibus -sub-bipinnatim 
ramulosis, ultimis erectioribus densioribus parciusque divisis. P. Davisii, nobis in Lond. Journ. Bot:
