172 MR. W. MITTEN ON THE SPECIES OF 
lanceolatam ramulis approximatis simplicibus divisisve pinnatim ramosi. Folia 
ramea erecto-patentia ovata, inde;in acumen elongatum loriforme planiusculum, 
apice latiuseulum acutum, margine serrulatum producta, subplicata, nervo infra 
apicem evanescente, e cellulis angustis areolata ; ramulina conformia, magis patentia. 
Perichætia foliis internis ovatis in acumen tenue serrulatum producta. Theca 
immersa ovata, operculo conico acuminato, peristomio parvo. 
Fertile specimens, “ Challenger ' Exp. ; Kintoki, Hakone, barren, Bisset. 
Rami frondiformes 11—3-unciales, parte stipitiformi unciali, foliis appressis, in medio 
frondis eum foliis 2 mm. lati. Folia fusco-viridia, siccitate parum mutata, longitudina- 
liter subplicata, apicibus semitortis tortisve. Perichetia ad os thece З mm. longa. 
Theca 1 mm. longa. Peristomium e dentibus teneris, lamina interna obsoleta. 
Very closely resembling the West-Indian and S.-American P. angustifolium, in size, 
ramification, and colour, with the same substriate leaves, which are not hollowed out as 
is so generally the case among the species of this genus. The Japanese species has the 
upper portion of its leaves more strap-like, more distinctly denticulate, and generally 
twisted, and the capsule is not so deeply immersed. 
97. PTEROBRYUM FASCICULATUM, Sp. n. Rami brevissime stipitati, ramulis pluribus 
approximatis pinnati subfasciculati. Folia imbricata patentia ovalia caviuscula, 
basi angulis ventricosis densissime areolatis carnosulis subauriculata, apice in 
acumen breve canaliculatum subserrulatum integerrimumve contracta, longitu- 
dinaliter subplicata, fere leevia, nervo medio evanido, margine late implana rectave, 
cellulis angustis areolata. 
Barren stems, ‘Challenger’ Exp. 
Rami 1-1j-unciales, ramulis 1-14 cm. longi, cum foliis 2 mm. lati. Folia fusco- 
viridia, sicca subnitentia. 
The specimens appear to be a small state of a species similar to the African P. Hanning- 
toni, more dense in foliage than the Javan P. convolutum and with wider leaves. 
Duby's P. imbricatum will be found under Climacium Japonicum.

98. M. PENSILE, sp. n. Rami penduli flexuosi, ramulis variis curvatis ramosi. Folia 
patentia dense inserta basi sese amplexantia, late cordato-ovata, alis basalibus convo- 
lutis, inde margine recurva flexuosa in acumen subulatum apice capillari contracta, 
nervo supra medium evanido, margine tenuissime serrulata, apice integerrima, e 
cellulis parvis angustis carnosulis obscuriusculis areolata. Flores masculi gemme- 
formes, antheridia septem satis magna includentes. 
А. few stems which appear to have grown in a pendulous manner, ‘Challenger’ Exp. 
Rami 6-10 em. longi, ramulis cum foliis vix 2 mm. crassis. Folia stramineo-viridia 
fuscescentia, haud nitida 
nitida, neque opaca, sicca parum mutata. 
In appearance similar to M. patulum and other allied S.-American species; but with
