ON THE PLANT REMAINS OF THE SCOTTISH PEAT MOSSES. 831 



it could be any other, D. strictum would be an interesting plant to find 

 occurring in Iceland at that period ; but under the circumstances it must 

 unfortunately be left out of account. A fragment or two of a peculiar and 

 quite unrecognised moss was also unhappily lost at the same time with 

 the Dicranum. 



Philonotis fontanel, Brid. One stem seemed to show an approach to the 

 characters of P. adpressa, but not very markedly. 



Mnium punctatum, L. 



Fontinalis sp. The same as in the second section in the third valley. 



Hypnum uncinatwn, Hedw. 



H. molluscum, Hedw. 



H. cuspidatum, L. 



Hylocomium triquetrum, B. and S. 



A similar association to those contained in layer 6 of the first valley ; the bulk 

 being aquatic mosses, such as would be found in or by a stream, while one or two are 

 terrestrial or rupestrial species which might have been brought down from the uplands. 



From another section in the third valley associated with Betula verrucosa : — 



Philonotis fontana, Brid. 



P. calcarea, Schp. ? 



Mnium punctatum, L. 



Fontinalis sp., probably F. antipyretica. 



Hypnum uncinatum, Hedw. 



H. cuspidatum, L. 



A similar series to those from the Betula verrucosa, Ehrh., layer in the first valley, 

 except that all are bog mosses or aquatic, none terrestrial purely. Fontinalis marks 

 either a stream or pool — not a bog.
