Has. Lord Auckland's group; on rocks in the sea, very abundant. 
Fila tenuissima, 4 unc. longa, rigidula, simplicia v. parum divisa, erecta, stricta, ramis lateralibus ornata. Rami 
seepius terni quaternive, verticillati, rarius bini, rarissime alterni, longissimi, filo primario longiores, erecti, strictissimi, 
simplices, ramulis omnino destituti, apice sphacelati. Ærticuli fili primarii diametro 7—8-plo longiores, clavati, geni- 
culis nodosis, ramorum cylindracei diametro 3—4-plove longiores. Color siccitate luride viridis, opaca ; planta vivente 
pallida, subhyalina.— Charte laxe adheeret. 
Very nearly allied to C. Aagelliformis, Suhr, a native of the Cape of Good Hope, agreeing with that plant in 
the remarkable ramification, but differing in the more slender habit, not being one half the diameter, and in having 
much larger articulations, especially on the main threads, which are singularly clavate with swollen joints, a character 
we do not observe in any states of C. flagelliformis. It cannot be confounded with any other species of the genus.

Has. Lord Auckland’s group; very abundant. 
Equally abundant in the Antarctic as in the Northern Seas. Montagne gives the C. adherens, Ag., as a native 
of this group,

1. Urva /atissima, Linn., Flor. Suec. no. 1159. Mont. Voy. au Pole Sud, Bot. Crypt. p. 33. 
Has. Lord Auckland’s group and Campbell’s Island; most abundant. 
The U. reticulata, Forsk., is mentioned by Montagne as a native of this group. 
38. PORPHYRA, Agardh. 
1. PORPHYRA capensis, Kützing. 
Has. Lord Auckland’s group and Campbell’s Island; on rocks in the sea. 
This differs from the European P. vulgaris in the rigid texture of the frond, which is not always simple in the 
Cape of Good Hope specimens. The P. colwmbina, Mont., appears to be the same plant.

Haz. Lord Auckland’s group; on the fronds of the smaller ۰ 
We have observed what we take to be this species, together with an Achnanthes and several other imperfect 
Diatomacee, upon Ptilota formosissima and some of the filamentous رما‎ amongst which is probably the Ach- 
nanthes brevipes, Ag. :
