ovato-lanceolata obtusiuseula, inferne convoluta, apicibus basin thecæ 
ovalis brevicollis octoplicatz attingentibus ; operculum convexo-acumi- 
natum ; peristomium dentibus latis 8, ciliis nullis. 
Hab. Ins. Ceylon, ad corticem, Dr. Thwaites. 
Caulis linea brevior, inferne radiculis rubris parce obtectus. Folia 
semilineam longa, mollia, viridissima, haud papillosa. Pedunculus 
linea brevior, pallidus. Theca fusca, collo brevissimo. 
Z. HUMILIS, Thw. et Mitt. 
Dioieus, parvulus; folia erecto-patentia, sublanceolato-ligulata, acumi- 
nata, nervo lato in acumen excurrente carinata, margine integerrimo, 
cellulis superioribus minutis rotundis distinctis lzevibus subpellucidis, 
inferioribus oblongis pellucidis; perichetialia pauca, subduplo longiora, 
erecta; theca in pedunculo brevi gracili, cum ejus collo ovali oblonga, 
opereulo conico rostrato ; peristomium dentibus latis 8, ciliis brevibus 
angustis 8. 
Hab. Ins. Ceylon, ad corticem, Dr. Thwaites. 
Caulis 4 lineas altus. Folia inferiora fusca, superiora viridia, linea 
breviora, strictiuscula. Pedunculus sesquilinearis. Theea fusca, pro 
plantula satis longa. Flos masculus non visus. 
Z. BREVICILIATUS, Thw. et Mitt. 
Synoicus ; caulis inferne fusco-tomentosus ; folia a basi brevi angustiore 
erecta, cellulis paucis oblongis pellucidis areolata, patentia, ligulata, 
flexuosa, acuta, nervo infra apicem evanido carinata, margine apicem 
versus denticulato, cellulis parvis rotundatis obscuris minutissime pa- 
pillosis; perichztialia intima brevia, lanceolata acuta, integerrima ; 
theca longe pedunculata, ovalis, in collum sensim angustata, ore parvo, 
operculo subulato obliquo; peristomium simplex, internum, ciliis bre- 
vissimis 16. 
Hab. lus. Ceylon, Dr. Thwaites. 
Caulis semiunciam altus. Folia pallide viridia, lineam longa. Pedun-

torto pungente, integerrima, nervo debili supra medium evanido, 
margine e seriebus cellularum angustissimarum tribus in limbum an- 
gustum callosum conflatis, cellulis amplis pellucidis; theca in pedun- 
culo recto, sporangio globoso, collo pyriformi breviore, operculo plano ;
