300 MR. W. MITTEN ON NEW SPECIES OF MUSCI FROM CEYLON. 
dimidio inferiore subelliptico concavo pellucide areolato, exinde ad 
apicem caulinis similia; theca in pedunculo brevissimo subsessilis, 
globoso-ovalis, rostello brevi erecto subobliquove terminata, calyptra 
parva plus minus profunde fissa; flos masculus foliis internis elongatis 
marginibus haud inflexis. 
Hab. Ins. Ceylon, ad terram. Dr. Thwaites. 
Plantule cum foliis lineam parum superantes. Folia perichetialia cir- 
citer lineam longa, omnia siccitate crispata viridia. Theca ob brevitatem 
pedunculi fere immersa. 
TortuLa, Hedw. Fund. 11. 92. 
Helicopodon, Mitt. Musc. Austr. Amer. 142. 
T. coNsANGUINEA, Thw. et Mitt. 
Dioica, humilis ; folia a basi parum erectiora, patentia, oblonga, obtuse 
acuta, integerrima, nervo percurrente dorso superne scabro, cellulis 
superioribus parvis rotundatis, inferioribus oblongis pellucidis, partem 
quartam folii longitudinis occupantibus, omnibus limitibus angustis 
distinctis; perichetialia inferne latiora, pellucidiora, ovato-oblonga, 
exteroquin conformia; theca in pedunculo rubro, oblongo-cylindracea, 
operculo subulato; peristomium thecæ longitudine equale, bis tor- 
tum; flos masculus satis magnus, foliis basi dilatatis cinctus. 
Hab. Ins. Ceylon, ad terram. Dr. Thwaites. 
Caulis 3-6 lineas altus. Folia semilineam longa, pallide glauco-viridia, 
sicca appressa curvata. Pedunculus sexlinearis. 
Macromitrium, Brid. i. 306. 
Goniostoma, Mitt. Muse. Austr. Amer. 194. 
M. ANGULOSUM, Thw. et Mitt. 
Rami humiles, ramosi; folia patentia, incurva, ligulata, obtusa, nervo 
percurrente carinata, integerrima, cellulis rotundis obscuriusculis, 
basalibus paucissimis oblongis pallidioribus; perichztialia breviora, 
lanceolata, acuta; theca in pedunculo breviusculo, sicca tetragono- 
ovalis, per longitudinem plicata, collo sensim angustato; calyptra 
nuda. 
Hab. Yos. Ceylon. Dr. Thwaites. 
Rami 2-3 lineas longi. Folia lineam longa, viridia, siccitate crispata, 
humida apicalia sepe apicibus incurvis. Pedunculus trilinearis, cras- 
siusculus. Theca humida leevis, sicca ore plicis contractis clausa. 
This nearly resembles M. goniopodum, Mitt. Musc. Aust. Amer. 
198, but has its leaves wider at their apices, and the capsule hasa 
longer neck.
