Leipzig, the specimen of " BarhuJa mnioidei^ " in the Herbarium 

 there. On the label of this specimen is written " Tortula. Barhula 

 muioidcs Sclmiiegv. Chile. Poppig m [isit] 5. 1829." The words 

 '' Barhida mnioides Schwaegr." are without doubt in Miiller's hand- 

 writing, and the moss, as was found on comparing it with the type, 

 is Tortida prostrata Mont., the Leipzig specimens only differing in 

 being a little less robust. In Hampe's herbarium, also, there are 

 two specimens, labelled in Miiller's handwriting *' Barhula mnioides 

 Schwaegr." — from "Chili, Poppig" and "Valdivia, Chili austral.," 

 both of which are T. prostrata. In Bescherelle's herbarium, the 

 moss labelled " Streptopogon mnioides Schwgr. Corral — Chili — 

 Krause " proves lilvewise to be T. prostrata. 



The following description of T. prostrata is drawn up from an 

 examination of Montague's type in the Paris Museum, except as 

 regards the operculum and peristome, which are absent in these 

 specimens ; these parts are therefore described from the Leipzig 

 specimens.
