170 МВ. W. MITTEN ON THE SPECIES OF 
green : it was described from Siebold's specimens as rufous, which it probably becomes 
in age, like its nearest species, Rhizogoniwm spiniforme.

This minute Moss agrees entirely in habit and colour with И. domingense, Е. ceyla- 
nicum, and Е. Hanningtoni. All have the fertile branches with larger leaves. Until the 
discovery of this species, the genus had been supposed to be gymnostomous. The 
typical species being F. domingense, in which the capsule is exserted, from this the 
Aulacopilum of Wilson differs only in its calyptra clasping at base, and opening laterally 
as in Calymperes. Considerably different from these species is the Leptocalpe (Е. coro- 
natum) of the * Musc. Aust.-Amer.,” in Journ. Linn. Soc., Bot. xii. 403, which C. 
Mueller thinks to be the same as Montagne’s Leptangium, the calyptra of which last 
is undescribed. In Æ. coronatum, as in Е. japonicum, the capsule is immersed. In the 
last it is of thin paper-like substance, pale green in colour except at the mouth, which 
has a band of orange-coloured cells corresponding with the teeth, which are regular in 
outline, smooth and wax-like in substance.

89. D. DENTATUS, sp. n. Caulis primarius repens. Rami decumbentes, demum penduli, 
ramulis inordinatis pinnati. Folia ramea patentia subdivergentia, sicca appresse 
imbricata, a basi ovata inferne marginibus recurvis caulem amplexante in acumen 
lanceolatum planum producta, nervo infra apicem remote dentatum evanido, cellulis 
superioribus oblongis basalibus ad angulos transverse oblongis. Folia ramulina 
angustiora fere ovato-lanceolata, siccitate magis appressa.

Very much like the Indian D. ferrugineum from the Nilgiri Mountains; but a little 
more slender, and with leaves a little shorter. Fruit has yet to be discovered for both 
species to be certainly placed in this genus; they are, however, unlike any species of
