European specimens.

C. TasManica (Mitten). Monoica, ramis elongatis inferne sæpe denu- 
datis superne ramulis brevibus ut plurimum fertilibus dense approxi- 
matis, foliis patentibus orbiculari-ovatis acutis nervo sub summo apice 
evanido margine e medio ad apicem minutissime. sed dense serrulato 
nullibi recurvo cellulis minutis ovoideis ad basin angustis elongatis, 
perichztialibus e basi ovali subulatis thecam ovatam longe superanti- 
bus, operculo convexo acuto, peristomio interno processibus angustis 
dentium longitudine in membrana brevissima annulo duplici. 
- Hab. Tasmania, on rocks, Jackey's Plain Creek, Mr. Archer. 
More robust than C. dilatata or C. Mülleri, the margins of its leaves 
not recurved below, and the perichetial leaves more subulate, but of the 
same habit and colour. 
C. CRENULATA (Mitten). Monoica, ramis pinnatis, foliis late-ovalibus 
acutis obtusisve concavis nervo paulo ultra medium evanido margine 
apice crenulato inferne recurvo cellulis minutis ovoideis basi elongatis, 
perichetialibus convolutis thecam paululo superantibus acuminatis 
. apicibus erosis, theca ovali, operculo conico acuminato. 
Hab. Victoria, Tarwin, Dr. F. Mueller, No. 107. 
Habit of the branches more nearly that of C. patens, but closely allied 
to C. dilatata, and, like it, probably a riparial species; from this, how- 
ever, it differs in the shorter nerve of the leaves, more robust habit, and 
more shortly acuminated perichztial leaves. 
З. Твлснуруз, Schw. 
Т. Новхвсносни (Mitten). Caule repente, ramis longissimis pendulis 
flexuosis subpinnatim ramosis, foliis e basi cordata caulem amplexante

apicem versus evanescente carinatis bistriatis e cellulis minutissimis 
subopacis margine pellucidioribus rotundatis areolatis, perichetialibus 
ovato-lanceolatis, theca in pedunculo brevi basi paraphysibus longe
