FROM THE FALKLAND ISLANDS, 201 
what it really represents ; but, in any case, Hohenacker’s specimen (No. 361), 
on which the Falklands record is based, appears to be only a form of 
P. umbilicalis. 
GIGARTINA PISTILLATA, Stackh. 
Known from a single species in herb. d'Urville (vide Hariot, '89, p. 69). 
The locality there given is probably incorrect. 
GYMNOGONGRUS IMPLICATUS, Kitz. (Ahnfeltia concinna, Hariot, Miss. Cap 
Horn, p. 71.) 
Howe has recently gone into the question of this species, and he regards it 
as a variety of Ahnfeltia Durvillæi, J. Ag. (Howe, '14, pp. 111-114). The 
Falkland Islands record is based on Hohenacker, Alg. mar. exsiec. no. 181, 
which is incorrectly named and is probably a small specimen of Gracilaria 
aggregata. 
CALLOPHYLLIS TENERA, J. Ag. 
It is doubtful if this plant, deseribed from the South Shetlands, is a good 
species; but, in any case, Hohenacker's Falkland record may be deleted, as 
his specimen No. 375 is a small thin fragment of C. fastigiata, J. Ag. 
RHODYMENIA SOBOLIFERA, Grev. 
An error for Callophyllis fastigiata, J. Ag. 
CHYLOCLADIA CLAVELLOSA, Grev. 
Based on an old and very doubtful record by J. Agardh (vide Hariot, 89, 
р. 76). 
NITOPHYLLUM FUSCORUBRUM, look. f. et Harv. 
This rests on Hohenacker’s Exsicc. no. 198. Тһе species may occur in 
the Magellan region, but the British Museum example of no. 198 (the only 
one I have seen) is almost certainly referable to N. lividum, Hook. f. et Harv. 
N. VARIOLOSUM, Hook. f. 
J. Agardh records this New Zealand species in his * Epicrisis ? (p. 453), 
but a specimen so named by him in the British Museum is referable to 
N. laciniatum, Hook. f. et Harv. 
DELESSERIA HYPOGLOSSUM, Lamu. 
See Hariot, 793, p. 93. Тһе specimen is probably D. phyllophora. 
D. rLATYCARPA, Lame. 
Recorded in error. See note under Nitophylla Durvillei, J. Ag., р. 182. 
LAURENCIA PINNATIFIDA, var. ANGUSTATA, Hook. f., Fl. Ла. 1. 184; ii. 484. 
The Falkland Islands records refer to a species of Chondria. See p. 186.
