542 MUSCI ANTARCTICI. 
wider, more rigid, less setaceous above and quite entire, the 
nerve broader, capsule longer, and the teeth of the peristome 
smaller, and scarcely bifid except at the apex. 
22. Dicranum robustum, nov. sp.; caule elongato subra- 
moso, foliis faleato-secundis longissimis lineari-lanceolatis 
setaceo-attenuatis convolutis spinuloso- serrulatis, nervo 
latiusculo excurrente, perichetialibus intimis obtusis 
mucronulatis enerviis convolutis, theca cylindrica incli- 
nata curvula strumulosa, operculo longirostrato. 
Has. Hermite Island. 
A larger species than D. pungens, differing in the longer 
more distinctly serrated leaves, with broader excurrent nerve, 
and the pericheetial leaves much shorter, capsule longer and 
strumose, teeth of peristome larger. It resembles D. majus, 
Turner, in general appearance, but has much longer leaves. 
23. Dicranum tenuifolium, nov. sp.; caule ramoso, foliis 
circinnato-falcatis e basi lanceolata longissime capillaceis 
integerrimis nervo lato continuo, theca suberecta turbinata, 
operculo longirostrato. 
Has. Hermite Island. 
Allied to D. falcatum, but leaves narrower and more pro- 
duced, and the capsule nearly or quite erect and smaller. 
24. Dicranum clathratum, nov. sp.; caule gracili subra- 
moso, foliis dissitis e basi quadrata vaginante linearibus 
patulis apice denticulatis obtusis solidinerviis, seta tortili, 
theca erecta turbinata, operculo longirostro, peristomii den- 
tibus bi-trifidis clathratis basi perforatis. ; 
Has. New Zealand. Under the falls of the Kidi-Kidi 
River. 
Nearly allied to Dicranum vaginatum, Hook., but of more 
slender habit, leaves more suddenly dilated below, more 
spreading and linear above, capsule not contracted below 
the mouth when dry, more tapering at the base, peristome 
very different in structure, and the operculum with a longer 
and more slender beak. |
