MUSCI ANTARCTICI. 551 
crispatis, pericheetialibus ovato-acuminatis, seta levi, theca 
ovata horizontali, operculo rostrato, calyptra subpilosa basi. 
fimbriata. 
Has. Bay of Islands, New Zealand. 
A small species allied to H. Dicksoni, but with the areola- 
tion of the leaf much more minute, calyptra like that of Dal- 
tonia splachnoides. 
53. Hook nz rotundifolia, nov. sp.; caule ramoso compla- 
nato, ramis compressis, folis imbricatis subdistichis ovato- 
rotundis apiculatis marginatis apice denticulatis seminerviis 
(areolis majusculis hexagonis), seta levi, theca elliptico- 
oblonga horizontali, operculo rostrato. 
Has. Bay of Islands, New Zealand. 
Still more closely allied to H. Dicksoni, but differs in the 
smaller leaves, with a broader denticulate margin. From H. 
crispula, which it also much resembles, it is distinguished by 
the rounder leaves, with larger and more uniform areole. 
24. LEsKEA, Hedw. 
54. Leskea nitida, nov. sp.; caule vage ramoso, ramis lon- 
Siusculis subsimplicibus teretibus, foliis imbricatis sub- 
erectis ovato-oblongis acuminatis concavis integerrimis 
basi binerviis, seta levi, theca cylindrica suberecta cur- 
vula, operculo brevirostrato. - 
Han. Hermite Island, Cape Horn, barren. Described in part 
from a specimen gathered in Staten Land, by Menzies. 
No. 18. 
Resembles Hypnum stramineum, but has the leaves acu- 
minated, and almost piliferous, and the operculum rostrate. 
25. Hypnum, L. 
56. Hypnum elongatum, nov. sp.; caule elongato robusto 
Subramoso, ramis elongatis, foliis erecto-patentibus ovato- 
lanceolatis apiculatis striatis serrulatis nervo excurrente. — 
Han, Lord Auckland’s group and Campbell's Island, 
n. 
Similar to H. densum, Sw.; but has leaves less attenuated
