276 MOSSES FROM THE 
Spores small. Operculum shorter than the capsule, conico-rostel- 
late. Calyptra reddish-brown, hairy, very small.— Dioicous ? 
It has some affinity with A. viticulosus, and its allies. The calyptra 
connects it with Lasia of Bridel. It is smaller than L. subcapillata, 
and is not easily to be confounded with any described species. 
Tas. X. B. Fig. 1, Plants, nat. size; f. 2, 3, portions of a plant; 
the latter with capsules, accompanied by operculum and 
calyptra; f. 4-9, leaves; f. 10, perichætium ; f. 11, portions 
of peristome :—all more or less magnified. 
30. Pterogonium lacum, (n. sp.) Caule repente parce ramoso, 
ramis brevibus vagis, foliis laxis subdistichis subsecundis ellip- 
tico-lanceolatis seminerviis, perichætialibus minoribus erectis 
acuminatis, seta brevissima levi, capsula ovata suberecta, oper- 
culo brevirostro, calyptra pilosiuscula. (Tab. X. E.) 
Has. With the last, on old trees, Chusan. 
In size and appearance very similar to the figure of Anomodon 
Grateloupii, Montagne (Ann. Sc. Nat. Aug. 1845, p. 100.), but 
different as to the peristome and calyptra, and the leaves not acu- 
minated. It belongs to Lasia of Bridel. A very minute species. 
Stems an inch long, creeping, leafy. Leaves not crowded, con- 
cave, minutely serrulate, perichætial leaves nerved half-way. Seta 
not two lines in length, flexuose. Vaginula slightly hairy. Oper- 
culum shorter than the ovate capsule, conico-rostellate, as in £no- 
modon Grateloupi. Annulus obscure. A rudimentary inner 
peristome is present. Spores rather large, greenish. Inflores- 
cence monoicous.

31. Neckera dendroides. Without fruit. Shaded bank on Cow- 
Loon side, Hong-Kong, Sam-Sa Bay. Appears to have grown 
on a tree. 
32. Neckera Beyrichii, Schwaegr. (?) var. foliis acuminatis. Pos- 
sibly a different species, but the characters very obscure. On 
a dry shaded rock, Pih-quan Island. 
33 and 34. Thesame. On old walls and trees, Chusan.
