neck, quickly becoming ovate-cylindric, 1:75 mm. long. 
Strize extending to the middle of the capsule, composed of 4-5 
series of rather wide cells, when dry prominent, furrowing the 
capsule to the middle. Stomata emersed, in lower part of 
sporangium. Annulus bi-triseriate, persistent. Peristome 
of 8 external teeth, red, laxly recurved when dry, in double 
pairs, entire, obtuse at apex, legs connected, jointed, joints 
very short, very densely papillose. Cilia 8 shorter, obtuse, 
papillose, reaching to half or more of the teeth, and having 
3-4 joints. Spores 24—26 micromill. in diameter. 
Hab.—Mount Wellington, on trees, W. A. Weymouth, No. 
895, New Town Rivulet ; and No. 897, St. Crispin’s. 
Akin to O. Tasmanicum, Hk. jf. Wils., but more than 
sufficiently distinguished by its much greater size and 
distinct strize, and other marks. 
6. Mniobrywm Tasmanicum, Broth., n. sp. 
Dioicous; cespitose. In tall, soft, pale, glaucous-green, 
somewhat loose tufts, not shining. Stems up to 8 cm. high, 
erect, flexuous, red, the lower part with fuscous radicles ; 
branching by slender, laxly leaved innovations up to 3 cm. 
long. Leaves of the stem patent, of the innovations 
patulous; all nearly equal, shortly decurrent, linear-lanceo- 
late, somewhat flat, acuminate, acute, about 3mm. long and 
0:47-0°53 mm. wide, margin erect everywhere, from middle 
to apex acutely serrulate, not bordered; nerve thin, about 
0:05.mm. wide at the base, vanishing below the apex; cells 
elongate, narrow, in middle of leaf 0°175-0°225 mm. long and. 
0015 mm. wide, all nearly equal, thin-coated, very smooth. 
The rest unknown. 
Hab.—On the wet banks of streams, Mount Wellington, 
W. A. Weymouth, No. 1,151 Falls Track; No. 1,153 St. 
Crispin’s; and No. 1,154 New Town Falls. 
Near Mn. albicanti (Wahlenb.), Limpr., but differing 
specially in the narrower and narrowly acuminate leaves, 
acutely serrulate from middle to apex, and likewise in the 
much longer and narrower cells, pointed at the ends. 
7. Cyathophorum densirete, Broth., n. sp. 
Dioicous; slender, green or pale-yellow-green, shining. 
Stem creeping, covered with dense reddish-fuscous tomentum ; 
stipites sparse, erect, slender, flexuous, apex more or less atten- 
uate, simple, black, densely leafy. Leaves scarcely altered 
when dry, patulous when wet, irregular in outline, base ventri- 
cose at the upper side, ovate, acute, margin erect, coarsely and 
acutely serrate from middle to apex ; nerve very short, rather 
broad, forked; cells rhomboid, firm and resisting, the upper 
0:045—0'06 mm. long and 0:015—0:020 mm. wide, margin 
narrow, forming an indistinct border. Amphigastria much
