there are not «'anting some which seem to indicate tliat, like some of the forms of Z. Novæ-Zelavdioe, the form of the
stipule may be considerably modified, as well as tbe habit of the plauts, by the situation in wliich they may have
grown.

H ad. Growing in water on the top of Fatigue Hill, elev. 4000 feet. A smaller form submersed :
St. Patrick’s River, Gunn. Wet places, iu gullies, near Brown’s River, Oldfield.
All the Tasmanian specimens of this plant are very much smaller than those from Hermite Island, but iu other
respects offer uothing to distinguish them. The species is au imdoubted Lophocolea, and is closely allied to L. palustris
{Jungemanniapalustris, Hook. fil. et Tayl. Flor. Antarct. p, 431. t. 157. f. 8), and to L. otophylla {Jungermannia
otophylla. Hook. fil. et Tayl. Flor. Antarct. p. 433. t. 158. f. 4), which has a trigonous, ovate-oblong perianth,
the lips entire aud undulate. Amongst the Antarctic species which have been eri'oneously refen'ed to Chilo-
scyphus are Lophocolea ftiscovirens {Jungertnannia, Flor. Antarct, t. 440. f. 7), where the figiu-e justly represents it
as a Lophocolea, and L. australis {Jungermannia, Flor. Antarct. p. 156. t. 65. f. 3), but the perianth is falsely described
and figured as bialate and büabiate, its true form being prismatic, and of course trilabiate.

Viridis. Caulis uncialis, prostratus, vage ramosus. Folia explanata, ceüulis teneris pellucidis hmitibus angustis.
Nearly allied to L. connata, Sw,, and L. Beecheyana, Taylor. From the first it differs in the form of the leaf
and emargination, the sinus being nairower, and the ceDs have thinner walls ; from L. Beecheyana, as well as from
Z. Martiana, Nees, it recedes in the entire ventral margins of its involucral leaves.—I*late CLXXVIII, Fig. 5 ; 1,

7. Loph ocolea amplectens (Mitten) ; caule cæspitoso decumbente vage subpinnatim ramoso exili,
foliis imbricatis subquadratis profunde emarginatis, laciniis acuminatis acutis amplectentibus, amphigastriis
ovatis bifidis, segmentis extus unidentatis. (T a b . CLXXVIII. Fig. 7.)

Jb/ia patentia, sinu lato emarginata, laciniis erectis subcomplicalis e celhdis parvis areolata. Amphigastna caulem
latitudine parum superantia, ambitu ovata.
In size and habit very nearly rcseinbliiig the European Uurpanthm scutatus, Spruce {J. scutata. Hook.), but its
leaves and stipules are of a different form, and were it not for the form of the stipule being exactly that which prevails
in almost all the species of Lophocolea, it would rank nearer to some Jungerniannue. Scraps of a species very
similar, or perhaps even identical, have been picked from amongst Lichens from Cape Horn, the Falklands, and
CampbeU’s Island.—P la t e CLXXVIII. Fig. 7 ; 1, a portion of the stem, with leaves and stipule :—magnified.

A small plant, readily distinguishable by its concave stipules, which have their two slender teeth bent back.
Ill general appearance it has more resemblance to some small forms of Plagiochila Mawitiana, Nees, thau to any
Lophocolea.—P la t e CLXXVIII. Fig. 6 ; 1, a portion of the stem, with leaves ; 2, the stipule, as seen on the ventral

Without exception the largest species of flic genus. In external appearance and colour it resembles C. Biliardieri,
but the form of its leaves, nnd particularly that of the stipules, wliich rcsemble nothing so much in outline as
the human occiput os seen from beluiid, render it very distinct fr'om all allied species. The united dorsal margins
