MR. W. MITTEN ON NEW SPECIES OF MUSCI FROM CEYLON. 297 
gine dorsoque serrulatis; theca in peduneulo elongato, oblonga, cur- 
vata, sicca et evacua pluries plicata, leptodermis, basi callosa, ore 
obliquo. : 
Hab. Ins. Ceylon. Dr. Thwaites. 
Caulis semiunciam altus. Folia bilinearia, fusco-viridia absque nitore, 
siccatione vix mutata. Pedunculus 9 lineas longus, ruber. Theca 
evacua pallide fusca, membranacea. 
This moss nearly resembles in size and general appearance 
D. virens, Wedw.; but its foliage is less curled, and the leaves 
are more narrow towards their points. 
CAMPYLOPUS, Brid. 
C. SUBULIFOLIUS, Thw. et Mitt. 
Caulis rigidus, radicellis rubrofuscis tomentosus ; folia sparsa patentia, 
inferne lanceolata, superne subulato-angustata, stricta, canaliculato- 
concava, nervo inferne 2 folii latitudinis, superne fere totam partem 
subulatam occupante, dorso apicem versus lamellis paucis humilibus 
parce denticulatis alato, margine erecto apice serrulato, cellulis alari- 
bus pluribus quadratis rubro-fuscis, inde viridibus angustis sensim in- 
ovales minutas transeuntibus; perichetialia basi ovalia convoluta, 
nervo in subulam angustiorem longiorem magis serrulatam educto ; 
theca ovalis gibba, ore obliquo, operculo rostrato, calyptra fimbriata. 
Hab. Yns. Ceylon. 
Caulis unciam altus. Folia lineas duas longa, superiora luteo-viridia, in- 
feriora fuscescentia, omnia apicibus concoloribus.

P. NITENS, Thw. et Mitt. 
Ciespitosum; caulis gracilis subsimplex fusco-ruber; folia erecto-patentia 
subsecunda, apicalia curvata secunda, sicca medio inflexa plana laxe 
contorta, elliptico-lanceolata, subulato-attenuata, nervo hyalino nitido 
usque fere ad summum apicem a pagina planiuscula distincto, mar- 
gine apice minute denticulata, cellulis alaribus pluribus quadratis ob- 
longisque flavis, superioribus ad marginem angustissimis hyalinis, 
in limbum latum nitidum usque ad $ folii longitudinis inferne 7 folii 
latitudinis oceupantem productum conflatis, interioribus minutissimis 
rotundis obscuris areolata. 
Hab. Ins. Ceylon Prov. central. in collibus altioribus, ad arborum trun- 
cos late cespitosum, vulgatissimum. Dr. Thwaites. 
Caulis subuncialis. Folia sesquilineam longa, pallide luteo-viridia, sub- 
glauca, nervo limboque marginali nitidis. 
Nearly resembling P. amene-virens, Mitt. Musc. Ind. Or. 
(Leucoloma), but with a much broader band of hyaline ceils on 
the margins of its leaves.
