19. J. incurvicolla, n. sp.; caule cæspitoso erecto apice in-

Tufts wide, blackish-olive. Stems about half an inch high, 
bending at their tops in the same direction. Leaves convex 
from the recurvation of both margins, round, yet slightly 
gibbous on thé inferior side, secund, those on the top of the 
shoot compressed, dentation large in proportion to the size 
of the leaf. Structure densely cellular. 
The present approaches nearer to Jung. punctata, Tayl., 
lately found in Ireland, than to any other of the tribe; from 
this it may be known by its smaller size, darker colour, 
its more round leaves, and their dentation more frequent as 
well as more minute. ; 
20. J. gregaria, n. sp.; caule cæspitoso erecto ramoso Capi- 
tato, foliis imbricatis erecto-patentibus secundis margine 
recurvis integerrimis, calyce terminali oblongo truncato 
apice scarioso integerrimo, capsula sphærica. 
Has. New Zealand. 
Tufts several inches wide, pale dusky olive-green. Stems 
two inches high, irregularly branched, branches erect. Leaves 
suddenly enlarging at the top of the stems into a flat capi- 
tulus ; entire, or, on the young shoots, showing now and then, 
only a single diminutive tooth; perichetial leaves subdenti- 
culate. Calyx large yet short, wide, oblong, split down on 
one side, the mouth subcompressed, whitish and skinny ph 
quite entire, Capsule globular. [um
