canaliculata, nervo crassiusculo a lamina vix distincto, subintegerrima,
cellulis inferioribus oblongis ad marginum laminis quadratis, peri-
chsetialia majora, a basi late obovata vaginantia laxius areolata nervo

Ascension, Dr. Seemann.
Very similar to D. proscripta, but with its leaves shorter, and
without the erect clasping base.

Specimens all without fruit. A dark-green Moss, from damp
rohdside banks on the high land.

Lesson, Melliss. Gathered also by Dr. flooker, and by Capt.
Haughton.
This species appears to be commonly fertile ; in general appearance
it has some resemblance to the European C.flexuosus, but all
the specimens are uniform in being of pale ochraceous brown, the
leaves quite without gloss, having at their bases the alar cells very
distinct and brown. Co'mpared by C. Mueller with C. Zollingerianus,
from J a v a ; it is also allied to some Brazilian species.
912. *C. scabricuspis, sp. nov.—Caespitosus, caulis erectus pa-
rum divisus. Folia sicca appressa, apicalia in gemmam acutam imbri-
cata, humida omnia erecto-patentia, inferne nervo lato folii latitu-
dinis £ occupante, lamina utrinque tenera cellulis angustis elongatis
basalibus parum latioribus, alaribus inconspicuis, areolata, supra folii
medium a nervo vix distincta, margine supra folii medium involuto
apice tantum parce denticulato, nervo pallido dorso apicem versus
denticulis pluribus scabro; folia perichsetialia basi lata ovalia lamina
laxiora, apicibus magis denticulatis—Melliss. A dark-green Moss,
from damp roadside banks on high land.
Stems from one to one and a half inches high, in general appearance
and colour similar to C. Helenieus, but with the apices of the
stems in the dry state thicker. This species appears to belong to
that group of the Campylopodes in which the nerve is very wide, but
soft and somewhat spongy in substance, and rarely accompanied by
distinct alar cells, the fruit being equal-sided, and the calyptra sometimes
without the fringe at its base. Species similar to the present
are found wherever the genus is represented.
918. fC. vesticaulis, sp. nov. — Compacte caespitosus, caulis
elatuS parum divisus fere ad apicem usque radicellis rubiginosis obtec-
tus. Folia erecto-patentia, sicca appressa apicalia in gemmam acutam
imbricata, lanceolata canaliculata sensim subulato-angustata, margi-
nibus conniventibus apice serrulatis, nervo tenui inferne folii lati-
tudinis | occupante, fere ad apicem a pagina distincto, lamina cellulis
oblongis, inferioribus pellucidis, alaribus propriis nullis, sensim in
minutis transeuntibus areolata, perichsetialia a basi latiora oblonga
convoluta, nervo angusto piliformi attenuato. Theca in pedunculo
brevi curvato ovalis leptoderma sequalis, siccà valde còntracta sub-
cylindracea plicata, interdum subarcuata, calyptra basi paucifimbriata.

to four inches high, below thickly covered with ferruginous rootlets,
above at the growing points, the foliage is pale yellowish-
brown.

banks on high land, Burchell, Melliss. All the specimens barren.—

915. *G. Helenicum, sp. nov.—Pulvinatum humile. Folia erecto
patentia stricta sublanceolata apice acuta cuculiata integerrima, nervo
crassiusculo percurrente carinata, cellulis superioribus obscuris
basalibus pallidis teneris angustis areolata, perichsetialia parum
longiora basi pellucidiora. Theca in pedunculo pallido ovalis, operculo
subulato.—Capt. Haughton.
Very poor and incomplete specimens have only been seen of this
species, without calyptra or peristome. I t is smaller than G. cuculla-
tifolium, found in S. Africa, and with narrower, less cuculiate
leaves. One or two stems of some Grimmia occurred amongst the
specimens of this moss, but quite insufficient to give any idea of
what species they may represent.
