166 MR. W. MITTEN ON THE SPECIES OF 
71. Ввүгм nosEUM, Schreb. Japanese name “ Kasa-goke.”’ 
Kintoki, Bisset; also gathered by Dickens, То Keiske, and Siebold ; all barren. 
It is recorded by Dozy and Molkenboer, and also mentioned by Sande-Lacoste as 
В. giganteum, Hook. 
MNIUM, Dill. 
Sect. Lumnium. 
72. М. TRICHOMANES, Мі. —2/. acutum, Lindb. in Act. Soc. Sci. Fenn. x. (1872) p. 227. 
With capsules just matured, * Challenger’ Exp. ; Ikegami, Nikko, and elsewhere, 
Bisset. 
This appears to be a common species, so frequently growing with other terrestrial 
Mosses; and is probably the М. cuspidatum, mentioned by Dozy and Molkenboer and 
in Ann. Mus. Bot. Lugd. Bat. ii. 294, to which it has a close resemblance in size and 
colour. 
73. M. nosrRATUM, Schwaegr. 
Nagasaki, Oldham; Kurosawa, Bisset. 
74. М. sPATHULATUM, sp. п. Dioicum. Folia laxe disposita, patula, oblongo-ovalia, 
suprema oblongo-spathulata, omnia obtusa, nervo in mucronem minutum excurrente, 
margine limbo e seriebus tribus cellularum composito simpliciter serrulato, cellulis 
parvis rotundatis areolata. Theca in pedunculo elongato rubro ovato-ovalis, pallida, 
nutans, operculo conico brevirostro. 
Small specimen of the female plant in poor state, sterile, * Challenger’ Eep. ; perfectly 
fruited specimens in May at Kurosawa, Shinano, Bisset; Nagasaki, Oldham; Tsus Sima, 
China, Wilford. 
Habitus, statura, faciesque omnino M. rostrati; foliis autem e cellulis minoribus areo- 
latis, floribusque diversis. Flores masculi in capitulis cyathiformibus acervati. 
There is a slight difference observable in the form of the capsule; it is slightly ovate- 
oblong, and not regularly oval. 
75. M. sPECIOsUM, sp. n. (Plate LI. figs. 6-9.) Caulis fertilis elatus simplex, inferne 
radicellis fuscis, foliis late oblongis obtusis retusisve. Folia superiora comalia 
longiora oblongo-lanceolata, patentia, nitida, nervo basi lato sensim angustato, ramulis 
pluribus in paginam dissolutis, apice in mucronem acutum excurrente, marginibus 
flexuosis limbo quadriseriato, ciliis pluribus zequidistantibus e cellula unica angus- 
tissima acuta formatis divergentibus ex apice usque ad basin angularum foliorum 
longe in caulem decurrentium fimbriata, cellulis transverse anguste oblongis, a 
nervo ad limbum marginalem in lineas sursum curvatas dispositis, parietibus angustis 
concoloribus areolata. Thecæ plures ex eodem pericheetio oblong, brevicolles, 
nutantes. Peristomium e dentibus processibusque castaneis. 
Yumoto, with fruit past maturity in August, Bisset. 
_ Caulis fertilis 8-4-uncialis, inferne subnudus. Folia inferiora brevia sensim versus 
comam longiora, comalia centimetrum longa, 5 mm. lata, omnia pallide stramineo-viridia,
