FROM THE CAMEROONS MOUNTAIN AND RIVER NIGER. 159 
bus, cellulis magis prominentibus basi paucis abbreviatis, perichzetiali- 
bus e basierecta ovata sensim lanceolato-attennuatis subintegerrimis 
patulis, theca in pedunculo longissimo rubro ovali inzquali horizon- 
tali pendulave, operculo conico longirostrato, peristomio interno pro- 
cessibus solidis ciliis singulis ejusdem longitudinis in membrana ad 4 
dentium longitudinis exserta. 
Hab. Fernando Po, alt. 3000-8000 feet, on stones up the mountain, Mann. 
Habit similar to that of S. fruticellus and S. reptans, but more robust, 
and approaching small states of S. tenuis, (Neckera) Hook. The capsule 
is sometimes regularly plicate, but not uniformly so. Very near to S. pseu- 
doreptans, C. Müller, but different in capsule and peristome. 
LEPIDOPILUM, Brid. 
L. DEVEXUM, sp. nov. Monoicum, caule parce ramoso, foliis compressis, 
lateralibus inæqualibus divaricato-decurvis asymmetricis intermediisque 
ovato-lanceolatis, mediis æqualibus minoribus, nervis ad medium pro- 
ductis, marginibus a medio ad apicem serrùlatis paululum recurvis, 
cellulis longitudine latitudinem duplo superantibus, perichætialibus 
parvis ovatis acuminatis, theca in pedunculo gracili brevi bilineari ru- 
goso apice flexo horizontali ovali, peristomio dentibus subulatis interno 
processibus carinatis angustis dentium longitudinis basi in mem- 
brana brevi exserta, calyptra sublævi subintegra. 
Hab. Cameroons Mountain, alt. 4000 feet, Mann. 
In size and appearance similar to L. latifolium, Müller, and the nume- 
rous closely allied South American species; but differing from all in its 
capsule being horizontal from the curvature of the very short seta, which 
is rugose, not papillose, and in the calyptra, which is more nearly smooth 
and entire than is usual in the genus. 
L. VERSICOLOR, sp. nov. Monoicum, caule depresso ramoso, foliis com- 
pressis, lateralibus patulis subarcuatis oblongo-lanceolatis apice latius- 
culo acutis, mediis intermediisque paulo brevioribus sursum angus- 
tioribus acutioribus ad medium binervatis, cellulis oblongis mollibus 
inferne longioribus, marginibus apice dense serrulatis, perichetialibus 
brevibus lanceolatis pedunculo elongato gracili sub collo theca ovali- 
cylindracez horizontaliter ruguloso, operculo conico acuminato, peri- 
stomio interno processibus solidis ciliis nullis. 
Hab. Fernando Po, Mann. 
Near to L. Utacamundianum, Mont., but with narrower leaves and smaller 
cells.
