166. Н. TOKIADENSE, sp. n. Caulis procumbens, ramulis pluribus erectis ramosis. -Folia 
ramea erecto-patentia, a basi cordata deltoidea, tenuissime subulata, margine ad 
angulos minutissime crenulata, alibi integerrima, nervo medio evanescente, quadri- 
plicata, e cellulis minutis versus apicem angustis, inferioribus oblongis, basin versus

imbricata, ovato-lanceolata, concava, bi- tri-plicata, apice vix vel brevi acuminata, 
latiuseula, minutissime serrulata, nervo infra apicem desinente, e cellulis per- 
angustis oblongis basalibus condensatis areolata; perichsztialia erecta subulata. 
Theca in pedunculo brevi erecta levis, sequalis ovali-cylindracea, opereulo subulato

A. small tuft of barren stems, * Challenger’ Exp. With young fruit and old capsules, 
Nantaizan, Bisset. 
Caulis procumbens 1-3 uncias longus, ramis plurimis semiuncialibus vel fasciculatim 
ramosus, ramulis semiunciam plerisque, brevioribus 2 mm. crassis. Folia viridia nitida, 
seniora ochracea, Pedunculus 1 em. altus. Тһеса 9 mm., opereulo 1 mm. longo. 
A little more robust than H. sericeum and Н. philippianum, but entirely of the same 
habit and appearance. The peristome is of the same kind; but the exact state of the 
internal peristome cannot be seen, and the calyptra is not present.

Rami 2-8 em. alti, cum foliis fere 3 mm. crassi, simplices, rarius furcati, in ceespitibus 
laxis aggregati. Folia vix nitida stramineo-viridia fuscescentia, sicca parum mutata, 
pluries plieata. Pedunculus 1 em. longus. Theca 2 mm. longa. 
A little more robust than H, sericeum, Linn., and almost destitute of the glossy foliage 
so evident in that species, and thus more nearly resembling the Leskea Bonplandii, 
Hook. Muse. Exot. t. lv., to which the Indian Isothecium nilgiriense, Mont. (Pleuropus 
_ fenestratus, Griff.), belongs, and of which a barren specimen was gathered on the city
