fs 1. CALLITHAMNION Plumula, Agardh, Sp. Alg. vol. ii. p. 159. 
Has. Hermite Island, Cape Horn; dredged up from about seven fathom water; very rare. 
Decidedly the same as the European and North American plant.

: C. Plumule simillimum, sed rigidiusculum, ramis latioribus, ramulis robustioribus articulisque brevioribus. 
This so closely resembles the C. Plumula, that it is difficult by mere words to discriminate them; yet, on 
| comparing them under the microscope, they are obviously distinct. CO. simile is a much coarser and more rigid 
dis, als | plant, with the ramuli more robust in proportion to the diameter of the articulation they spring from, and the articu- 
satis | lations themselves are shorter. Again, from the circumstance of the true C. Plumula occurring at Cape Horn, where 
-mü | this, (the only Kerguelen's Land species), does not appear, we incline to regard the present as a representative 
species rather than a variety. 
3. CALLITHAMNION Ptilota, Hook. fil. et Harv. ; parvum, rigidulum, setaceum, fronde pinnatim ramo- 
ns. Cir sissima, ramis vix distichis venoso-striatis subopacis, secundariis opposite pinnulatis, pinnulis simplicibus 
patentibus subulatis e quoque ramorum articulo ortis, articulis diametro duplo longioribus. Nobis in Lond.

l Has. Crozet Islands; on a floating mass of Macrocystis pyrifera. 
Frons 1-2 unc. longa. Caulis crassitudine setæ equinæ, repetitim pinnatim ramosus; ramis suboppositis 
i | patentibus demum deflexis, inferioribus subuncialibus ; secundariis breviusculis pinnatis, pinnis plurimis densis, 
oppositis, simplicibus, subulatis, e omni articulo rami ortis. Color fusco-ruber :—chartee vix adheeret. 
Only one specimen of this very distinct little species was found : it grew on a piece of floating sea-weed, picked 
up at a considerable distance from the shore.
