308 MR. W. MITTEN ON NEW SPECIES OF MUSCI FROM CEYLON. 
A. ABBREVIATUM, Mitt. 
Monoicum; folia compressa, dorsalia imbricata, directione patula, ob- 
longo-ovalia, symmetrica, obtusinscule acuta, ventralia angustiora di- 
rectione vix diversa, apicem versus latiuscula, lanceolata acuta, cellulis 
parvis rotundis obscuris areolata, papillis minutis ubique erosa ; peri- 
cheetialia convolutacea, ovalia acuta ; theca in pedunculo brevi pallido, 
brevis, poculiformis, operculo breviter conico acuminato; calyptra 
lobis breviuseulis appressis, apice acuto subscabro ; flos masculus gem- 
miforinis. 
Hab. India orient. ad caudices tomentosos filicis cujusdam repens, JW. 
Bell. 
A. glauco A. tumiduloque statura simillimum, foliis autem dorsalibus 
apices versus latis obtusiusculis, angulo obtuso terminatis, et theca et 
calyptra brevioribus. 
A. INCANUM, Mitt. 
Monoicum, pinnatim ramosum ; folia compressa, dorsalia patentia ovata 
apice in acumen angustum diaphanum producta, ventralia dimidio mi- 
nora ovato-lanceolata, cellulis rotundatis obscuris, papillis minutis ; 
perichactialia erecta, interna, convolutacea, ovata subacuminata; theca 
in pedunculo pallido subzquilongo, ovalis, operculo breviter conico- 
acuminato ; calyptra ad perichztium usque descendens, apice sub- 
scabra; flos masculus gemmiformis, foliis acutis. 
Hab. Africa australis, East London, ad corticem, beatus Rooper. 
This closely resembles 4. glaucum, but has the points of its 
leaves diaphanous. 
Erpodium Beccarii, C. Muller, Venturi in Nuovo Giornale Bo- 
tanico Italiano, fasc. i. p. 18, is clearly, from its description, an 
Aulacopilum, and is stated to have leaves with an elongate hyaline 
bair-point, by which it much differs from 4. incanum. 
Anomopon, Hook. 
A. FILIFORMIS, Thw. et Mitt. 
Caulis procumbens, ramis ramosis subpinnatus ; folia caulina erecto-pa- 
tentia, undique disposita, basi subovata, acumine lato ligulato obtuso, 
nervo tenui medio evanescente, ramea compressa patula ovato-oblonga 
obtusa, nervo supra medium evanido, ob prominentiam papillarum 
margine crenulato, cellulis parvis rotundis papillosis obscuris. 
Hab. Ins. Ceylon, Dr. Thwaites. 
Caulis unciam longus; rami bilineares. Folia intense viridia subglauca. 
This appears to be a species less than A. tristis, Cesati; and, so 
far as can be seen by the specimens yet examined, the habit seems 
more depressed.
