for the size of the moss. Beak of the operculum inclined. 
Teeth of the peristome 16, pale, very long and narrow, 
united at the base by a common membrane. Calyptra 
naked, except a few setulæ at the apex, brown. Spores 
yellow and small. 
Allied to P. compressum, (Hook. et Wils.), but differing 
quite in the peristome, having only 16 teeth, as in Cephalo- 
trichum of Bruch and Schimper. The male flowers we have 
not seen. In this moss the peristome, more evidently than 
in other species, is found to consist of two lamine, the inner 
one continuous with the sporular sac.
