314 MR. W. MITTEN ON NEW SPECIES OF MUSCI FROM CEYLON. 
foliis erectis lanceolatis integerrimis convolutis immersa, operculi 
rostro brevi obliquo; peristomium depressum, dentibus brevibus co- 
herentibus, vestigiis tenerrimis processus adh:zrentibus. 
Hab. Ins. Ceylon, Dr. Thwaites. 
Crassitudine caulium G. plicate similis, primo visu tamen ex omnibus 
speciebus hucusque descriptis foliis haud plicatis distincta. 
G. TORTIFOLIA, Mitt. 
Caulis eurvatus, ruber, inter folia conspicuus ; folia subcompressa, diver- 
gentia, semitorta, ovali-elliptica, sensim in acumen longiusculum an- 
gustum leve producta, plicis tribus dorso levibus exarata, parum 
excavata, margine late implano, superne denticulis angustis serrato, à 
medio ad basin usque revoluto, breviter binervia, cellulis angustis areo- 
lata; pericheetialia late ovalia, sensim acuminata, acumine erecto, inferne 
dentieulis paucis remotis inconspicuis serrata, apice integra; theca 
immersa, cylindracea, opereulo acuminato obliquo. 
Hab. Ins. Borneo, Sarawak, Everett. 
G. eleganti quoad formam foliorum similis, directione autem eorum di- 
varicata et theca immersa statim dignoscitur. 
G. compressa, Mitt. 
Caulis elongatus, curvatus; folia compressa, patentia patulave, stricta, 
elongate lanceolata, apice latiuscule acuta, basi parum latiora, plicis 
tribus statu sicco distinctioribus exarata, planiuscula, enervia, margine 
apicem versus denticulato, cellulis angustis areolata; perichetialia 
parva, late ovalia, acumen versus breviter denticulata; theca in pedun- 
culo zequilongo, evlindracea, operculo oblique rostrato. 
Hab. Ins. Borneo, Sarawak, Everett. 
More slender than G. angustifolia, and with narrower leaves, 
whieh are not acuminate. Unlike any other species in its narrow, 
flat, compressed leaves. 
G. cARINATA, Mitt. 
Caulis inferne decumbens, rarius divisus; folia patentia, interdum subse- 
cunda, ovata, vel ob margines basi reflexos latissime lanceolato-ovata, 
in acumen pungens dentatum sensim producta, concava, infra acumen 
parum excavata, tri- quadriplicata, breviter binervia, dorso denticulis 
paucis scabriuscula, margine denticulis serrato, cellulis parvis angustis 
oblique seriatis areolata ; perichzetialia parva, erecta, ovata, apicedentato- 
lobata subintegrave acuta, convoluta ; theca in pedunculo breviore, sub- 
curvata, oblongo-cylindracea; peristomium depressum, dentibus sub- 
horizontalibus apicibus incurvis inferne cohxerentibus rubris. 
Hab. Bootan (herb. Griffith). 
A robust species, with leaves less densely inserted than they 
are in G. plicata and less spreading than in G. elegans; there 
are present on the back of the leaf a few scattered teeth of the
