Miller (J. c.) founded the bows genus with the dicwinn ie: 
ters :—‘‘ Peristomium duplex; dentes externi 16 angustissimi sub- 
ula trabeculati linea longitudinal plus minus evoluta vel obsoleta 
xarati colorati, interni: cilia totidem capillaria pallidiora. externis 
anion ga, membrana imine carentia, parum suleata et ad carinam 
linea longitudinali hic illic secedente percursa; calyptra dimidiata.” 
Further (/.c. p. 447), in his Conspectus Fabrontacearum, the inner 
peristome of Schwetschkea is described as consisting of.“ cilia 16

In thie genus Schwetschkea Miiller described three new species, 
and also referred to it Neckea pyymea Dozy & Molkenb. Ann. Sci. 
Nat. iii. sér. mu. 813 (1844). Of the la Akad species, and of two 
other species, viz. Pterogonium lawum Wils. Lond. Journ. of Bot. 
vii. 276 (1848), and Neckera gracillima Tayl. l.c. 192, Miiller_ob- 
served as follows :—‘* Wie weit es pygmea Dz. et Mb., welche 
die Bryol. Javanica (ii. p. 180) gewiss ganz richtig als Fabroniacee 
erkannte, wenn sie auch das Moos sicher nicht richtig als dnacamp- 
todon p ygmaus Lac, palit lasst; wie weit Neckera lawa Syn. Muse. 
(Pterogonium laxum Wils.) von der chinesischen Insel Tschusan, und 
wie weit Neckera gracillima Tayl. vom Pichincha bei Quito hierher 
gehort, weiss ich nicht zu entscheiden. Ich vermuthe nur sehr 
stark, dass die N. pygmen von Borneo eine Schwetschkea sei, weshal 
ich sie auch derselben unten einflecten werde.” Apparently on te 
strength of the above remarks, we find Jesee in his poe)

Now, the fundamental generic character of 'Saksoesshidd is found, 
according to Miiller, in the structure of the inner peristom e, which 
is vagy by this author as consisting of cilia-like teeth ‘with no 
trace of a basal n turning to the figures of Leskea 
senna in Musei Archip. Ind. tab. xlix., however, we find cilia 
of the internal eee represented as springing from well- 
developed basal membrane which reaches to a quarter of the wont 
of the teeth of the axterual aden Having had an opportunity 
of examining the fruit of a moss which I believe to be this species, 
and of three other species which es been referred to Schwetschket,
