standing Wahlenberg's remark upon S, luteum, " tutissima ut etiam 

 facillima differentia hujus et praecedenti speciei {S. ruhrum), in colore 

 umbraculi consistit," there are intermediate states as to colour and 

 every other particular, which would warrant a botanist in uniting the 

 two. So splendid, indeed, is this colour in the apophysis of the true 

 S. ruhrum, of Hedwig, that Wahlenberg further says of it, " adeo satu- 

 ratissimus et elegantissimus, ut nihil in natura pulchrius esse queat." 

 Splachnum heterophyllnm and intermedium are new species. S. arc- 

 ^ecwm of Brown. Systyliiim splachnoides of Hornschuch; and Tayloria 

 splachnoides of Hooker. Conostomum horeale. Grimmia cali/ptrata 

 and Ilookeri (nov. sp.). Drummondia davellata Hook, (the Gym- 

 nostomum prorepens Hedw.) Scouleria aquatica Hook. ; in the pre- 

 sent work, ^. 18. Weissia turbinata, allied to W. splachnoides and 

 macrocarpa (n. sp.). Dieranum julaceum, Richardsoni, and microcar- 

 pon (n. sp.). Didymodon oblongifolinm oxiA fragile (n. sp.). Tor- 

 tula bryoides and suberecta (n. sp.). Neckera Menziesii (n. sp.), but 

 previously discovered in the north-west coast of America by the gen- 

 tleman whose name it bears. Hypnum vagans and pulchrum (n. sp.). 

 Hypnum confervoides Bridel. H. obtusifolium (n. sp.). H. robustum 

 {Hooker, Exot. Muse). H. abietinum (in fruit) ; and the variety called 

 scitum. H. erectum (n. sp.). H. neckeroides (Hooker, Muse. Exot.). 

 Climacium americanum, a very noble plant, quite distinct from C. den- 

 droides of Europe, which is also in the collection. Fontinalis capil- 

 lacea. Bryum turgidum, triquetrum, demissum (Muse. Exot.). Cin- 

 clidium stygium. Timmia megapoUtana. Arrhenopte.rum heterosti- 

 chum, and Polytrichum angustatum, Bridel, and Hooker Muse. Exot. 

 ^c. : together with many of the rarest species which have already been 

 known to inhabit Europe or the United States of North America. 



These Mosses are neatly arranged (the specimens being fastened 

 upon each leaf of paper) in two 4 to volumes, of the same size with 

 the forthcoming Fauna of these regions by Dr. Richardson, and the 

 general Flora by Dr. Hooker, and as the Narrative of the Journey by 

 Captain Franklin, to which the Natural History portions may be con- 

 sidered as forming an Appendix. The whole will then constitute a 

 very complete history, both as to geographical discoveries, scenery, in- 

 habitants and productions, of an immense extent of countiy, which 

 but a few years ago was considered as a " terra prorsus incognita."
