54 MR. MITTEN ON SOME NEW SPECIES OF MUSCI 
uoso rubro lsevi apice (sicco) ruguloso ovali cernua ; operculo subulato gequilongo ; 
peristomio satis magno, dentibus medio linea pallidiore notatis valde trabeculars 
crassis, interno processibus paulo longioribus solidis in membrana ad tertiam partem 
dentium longitudinis producta ; calyptra superne scabra. 
Hab. River Niger {Vogel) ; Nupe {Barter). 
Leaves narrower than in any of the described species ; seta smooth below, appearing slightly rough in 
the upper part when dry.

Hab 
A small species agreeing in size and habit with the Javan F. Zollingeri, but with leaves of a firmer 
substance, of an obscure olive-brown colour. 
Tab. V. fig. 10. 1. Plant (natural size) ; 2. the same, and 3. a leaf (magnified). 
F. OPACiFOLius, Mitten. Monoicus, caule brevi ; foliis patentibus late lanceolatis acutis 
siccitate non mutatis, lamina vera ad medium producta subinaequali crassiuscule 
hyalino-marginata, lamina apicali latiuscula dorsalique tenuiter crenata, cellulis opacis 
obscuris, nervo pellucido luteo percurrente ; theca in pedunculo bilineari ovali erecta, 
operculo subulato, peristomio generis, calyptra basi integra papillosa, floribus masculis 
gemmiformibus in foliorum caulinorum axillis reconditis. 
Hab. River Niger {Vogel) ; Natal (Guenzius). 
The opaque rather broad leaves^ pellucid nerve, and strongly margined border of the true leaf distin- 
guish this species from its allies. The calyptra resembles that of F. serratus from the Nilgiri Mountains.

¥. RA^irLOSTTS, Mitten. Dioicus ? caule fertili brevi, ramis gracilioribus e basi egredientibus 
ramoso ; foliis patentibus siccitate crispatis lanceolatis immarginatis, lamina vera ad 
medium producta apice subinaequali, nervo subpellucido percurrente, marginibus 
ubique tenuiter crenatis, cellulis minutis obscuris diametro xrunr uncise metientibus ; 
theca in pedunculo triliueari gracillimo ovali erecta, operculo subulato, peristomio 
generis, calyptra basi integra lsevi. 
Hab. River Niger [Vogel). 
Allied to F. elegans, Schw., but with a different habit. From F. opacifolius it differs in the absence of 
margin to the true leaves, as -well as in their form and in the inflorescence, and also in the smooth calyptra.
