FROM THE FALKLAND ISLANDS, 173 
Distris. Atlantic and Arctic Oceans, Mediterranean, North Pacific 
(Japan and America), S. Peru, Fuegia, Falkland Islands, 8. Georgia. 
The forms assumed in the subantarctie are very similar to those found in 
Europe.

DısTRIB. Falkland Islands, S. Georgia, Kerguelen (?). 
See notes under Cæpidium antarcticum, р. 168. Skottsberg's account of 
the bladder-like shoots seem to prove that the plant cannot be referred to 
Colpomenia sinuosa. The forked basal branches described by him would 
appear to be part of the Colpomenia plant (and not of the Chordaria), and 
these are unlike anything found in the ordinary Colpomenia of Europe. 
Skottsberg refers to Mitchell's account, and gives other reasons (p. 44) why 
he cannot identify it with the C. sinuosa of warmer seas. It may be noted 
here, however, that, since the publication of his report, Colpomenia has 
appeared in the English Channel, and from the variability in the distribution 
of the sporangia and tufts of hairs shown by British material, it is evident 
that some of the reasons advanced by Skottsberg will have to be reconsidered, 
and that before it is possible to express a definite opinion on the identity of 
the various extra-European forms a detailed morphological and anatomical 
study of old C. sinuosa of the Mediterranean is necessary. 
Mrs. Vallentin collected several specimens at Roy Cove, but from dried 
material it is impossible to throw further light on so difficult a problem. 
Pending further investigation оЁ preserved material I have left the plant as 
Colpomenia sp. 
UrricuzipiuM DURVILLEI, Skottsb. Subant. u. Ant. Meeresalgen, 1. p. 36. 
Adenocystis Durvillei, Hook. f. et Harv. in Fi. Ant. ii. р. 468.

Disrris. Fuegia, Falkland Islands, 8. Georgia, Kerguelen. 
On the ground of the plurilocular sporangia Skottsberg separates Adeno- 
cystis Durvillei from Л. utricularis, Skottsb. (= A. Lessonti, Hook. et Harv.), 
and raises it to generic rank. There appear to be no specimens of this 
species in the Kew Herbarium.
