Mixed to some extent with E, anreum this species was at first sight not 

 ■oasy to separate, but under the microsco].)e the cell-structure at once dis- 

 tinguishes it; the cells are not remarkably wddej though wide for the si/e of 

 ]oaf, but, being quite empty and the walls extremely thin, the texture is 

 xcmarkably delicate and pellucid ; and in the branch-leaves the marginal 

 colls form a still more hyaline border; the leaves arc less strongly falcate 

 than In the two previous species,

I had described (and distributed) this plant as CaUiiitominm ].>^tim(Oiiuu^ n. gen. k sp. 

 Since, liowevcr, the MS. of tliis paper \vas iu the printer's hands I havo ascertained its 

 identity with a New Ireland plant collected by Micholitz in 1SD3, described by Brotherus 

 (ung^inally under Uctropof/teciiun as above^ but now recognized by liiui as congeneric with a 

 Philippine Is. moss for wliich he created in 1913 tlie genus lHa(jiothcehpsis (Piulipp, Jonrn. 

 Sci, viii. 87), 



The genus differs from J "e^/cie/ifna principally in the distinct structure of the peristome, 

 ;uid as both genus and species are little known I have let the description stand. — II. N. D.,
