Hitherto knowm only as an inhabitant of the seas of the Northern hemisphere; where its range is uot wide
In the southem it appears to be confined to the extreme south of America, flom-ishing in the deep bays whieh indent
the coasts of Fuegia. Some specimens are altogether sbnilar to those of European growth; others of which we
have constituted the var. lanei/olia are larger, longer, sometimes almost a foot long, much nan-ower, and more
attenuated at both ends. I t is a veiy handsome variety.

This is perhaps most closely albed to D. sanguìnea, from whieh it maybe distinguished by the altcruatc
nervation and dividing of the frond. The D. alata, whieh it is also near, differs in the texture and colon.- of
frond. No fruiting specimens were found.
P late CLXXV. The absence of fructification precludes the necessity of dissections.

H ab. Falkland Islands ; abundant in Berkeley Sound and Po rt VfiUiam.
OriginaUy discovered at the Cape of Good Hope, where it is very abundant. More recently it has been
gath ered in the coast of California, whence its existence in the Ealkland Islands might have been considered
probable, even before its recent discovery in that part of the Southem Ocean. It is very plentbnl on the long
shelving beaches of the islands in question, but was not seen on the deeper and more rocky shores of Fuegia.

Were tbe vai-. /3. found upon tbe coast of Europe, it would be undoubtedly referred to D. hypoglomm, and it
may well be considered very doubtful whether the D. crassinervia of the Southem Hemisphere be the representative
of its northem congener, into the likeness of which it varies ; or whether, as is perhaps more probable, both
are not varieties of the same species. The tme D. ruscifolia is a native of the Cape of Good Hope, of Tasmania,
and, according to Gaudichaud, of the Falkland Islands also.

H ab. Hermite Island, Cape Horn, and tb e Falkland Islands ; most abundant b oth on tb e outer coasts
•and in the harbours.
A veiy handsome species, of which M. Bory gives a sufficiently characteristic but discoloured figure. The
origbial colour of the plant is a rosy or vinous red. In every respect, except the position of the granules, which
are here scattered over the surface of the frond, tbis is very nearly albed to D. sinuosa, Ag.

A I'ery noble species, of which fine specimens were cobected, thrown up on the stony shores of Kerguelen’s
Land and the outer coasts of the Fidkland Islands ; and which, as it was never seen attached, either in the shabow
or deep bays of any of the coasts visited by the Expedition, finds, we conclude, a congeuiid home amongst tbe wild
breakers that fringe many parts of these iron-bound coasts. Specifically it is albed to the European B. sinuosa,
