means as I had at command, I conclude these masses to be 
the work of some insect. I noticed this species only to be 
so ornamented. H. atrovirens, (275, n. sp., W.C.) a small 
dirty-looking species found on wet rocks and stones in low 
shaded spots, is apparently very near H. flexuosum, R. Cunn., 
differing, however, in its involucre, &c. the involucre in that 
species being “ orbiculate.” H. revolutum, (276, n. sp. W.C.) 
a small species, epiphytal on the reclining branches and 
trunks of trees, in damp and shaded places ; in affinity very 
near H. Tunbridgense. The deeply laciniated margins of the 
segments of its frond, will, however, be found constantly re- 
volute. After allit may prove but a variety of H. Tunbridgense, 
of which English species I have not an accurate description. 
The elegant little 77. semibivalve (277) grew plentifully 
here on fallen and reclining trees. A handsome species of 
Polypodium (278) apparently a variety of P. Grammitidis, 
R. Br. but having its lobes deeply incised and sub-pinnatifid ; 
and an elegant species of Grammitis, (279, G. ciliata, n. sp. 
W.C.) I also obtained in this locality. Both these ferns are 
epiphytal on living trees. G. ciliata has close affinity with 
G. australis, R. Br. from which, however, it differs in its 
being a much smaller plant, in having its sori more prominent 
and crowded, and in being villous underneath and beautifully 
ciliated at the margin. Several charming mosses (280) too, I 
gained during my very short stay here, among which I was 
very much pleased to find in fruit the very beautiful one 
whose fronds I had before detected in a wood near Turanga, 
(vide sp. No. 45). The mosses (280) must speak for them- 
selves ; I hope, however, that some new species may be found 
among them. 
. The next morning I recommenced my journey; experiene- 
ing no little difficulty in the obtaining of a guide over the 
mountains, in which service I was obliged to enlist all my 
persuasive powers. We commenced ascending from the shores 
of the lake, through dense woods chiefly composed of Jwerba 
and Fagus. Having. gained the summit of the range we 
found travelling easy ; for, in these forests where the broad-
