S. CIRCINALIS, Hook. Muse. Exot. t. 107. 
Hab. Vancouver Island, Lyall. 
S. PLUMIFER, sp. nov. Dioicus, cwspitosus, ramis procumbentibus, 
ramulis approximatis plumiformi-pinnatis, foliis falcatis secundis e basi 
latiore subovato-lanceolatis sensim tenuiter angustatis hamatis sic- 
citate subplieatis, nervis tenuibus brevibus, marginibus inferne reflexis 
integerrimis, in ramulinis apice serrulatis, cellulis ad angulos paucis 
abbreviatis subobscuris, superioribus elongatis angustis, perichetialibus 
elongatis erectis pallidis late lanceolato-subulatis apicibus serrulatis, 
theca in pedunculo elongato longe cylindracea suberecta curvata, 
operculo brevi subulato rostrato, peristomio dentibus pallidis teneris, 
interno tenero processibus latiusculis perforatis ciliis binis zequilongis 
angustis interpositis in membrana alte exserta. 
Hab. N. America, Drummond ; Canada, Shepherd; Columbia, Douglas ; 
N.W. coast of America, Douglas and Menzies; Pack River, Lyall. 
Very common on trees and on the ground in British Columbia, Lyall; 
Vancouver Island, Lyail. 
Shining yellowish green, becoming in age pale brown, more 
slender than ZZ. imponens, and in habit approaching more to H. 
crista castrensis. In its narrow glossy leaves, long curved capsule, 
and rostrate operculum it is sufficiently distinct from H. imponens 
and H. hamulosum. This may be the H. subimponens, Lesq.; but 
the operculum is different from that described in the short account 
of the species. 
S. cRISTA CASTRENSIS, Linn. 
Hab. Saskatchewan, Bourgeau. 
S. RoBvsTUS, Hook. Musc. Exot. t. 108.

Very few specimens, which give no further information as to 
the habit of the species. 
Belonging to this group are also— 
S. COMPLEXUS, sp. nov. Dioicus, late czspitosus, ramis pinnatis, foliis 
secundis e basi latiore ovato-lanceolatis hamatis concavis nervis binis 
brevibus marginibus subintegerrimis, cellulis ad angulos pluribus 
abbreviatis subquadratis obscurioribus, superioribus elongatis angustis 
apicibus quasi prominulis, perichetialibus elongatis erectis oblongis 
subulatis, internis lanceolatis subito subulatis subserrulatis plicatis, 
theca in pedunculo rubro cylindracea inzquali inclinata, peristomio 
dentibus flavis e medio subulatis, interno processibus angustis ciliis 
binis interpositis.
