316 MR. W. MITTEN ON NEW SPECIES OF MUSCI FROM CEYLON. 
apicem versus incurvo, integerrima, nervis binis basi conflatis, cellulis 
angustissimis, basalibus nullis diversiformibus areolata ; perichzetialia 
erecta, exteriora brevia, interiora elongate oblonga concava, versus 
acumen subulatum parum excavata, ad thecam oblongo-ovatam brevi- 
pedunculatam emergentem appressa; peristomium et humidum et 
siccum in conum acutum prominens e dentibus angustis firmis dorso 
articulationibus prominentibus denticulato-asperis pallide fuscis com- 
positum.—Meteorium crassicaule, Mitt. Musci Ind. Or. 
Hab. Ins. Ceylon, Rambodde : Gardner, no. 9; Thwaites, no. 181. 
This fine species in size and appearance very nearly resembles 
the Meteorium crassicaule (C. Müller), Bryol. Jav. t. 210, but 
differs in its more elongated branches, which produce but few 
flagelliform shoots. The leaves in all the specimens are of a rich 
glossy brown colour, except towards the apices of the stems, where 
they are straw-coloured and less glossy ; they are destitute of any 
longitudinal folds. The Meteorium flexipes, Mitt. Muse. Ind. Or., 
in foliage and appearance nearly resembles P. ceylanicum ; but its 
capsule is exserted. All these species present characters which 
are rather those of Pterobryum than of Meteorium ; for they are 
not species having a pendulous habit.
