MEESIACEzE. 



Aulacomnium palustre, ScJnuceg. In wet places about shores, or even 

 in the water ; frequent in all the Areas. 



BARTRAMIACEyE. 



Philonotis fontana, Brid. "I.," IV., VII. On wet shores or at the 

 margin of the water ; common in IV., and occurring in all the other 

 Areas sparingly. P. calcarea, Schp., occurs on the boggy shore at the 

 S.E. end of L. Leven, where there are probably seams of lime. 



Breutelia arcuata, ScJip. IV. On rocks, generally scarce at the loch 

 shores, but it grows in magnificent luxuriance at Loch Dungeon. 



BRYACEvE. 



Several species of Bryum occur, but seldom in abundance. B. alpinum, 

 Huds., is sometimes noticeable on rocks of the liill lochs in Area IV. 

 B. bimum, Schreh., occurs in scattered patches on wet or boggy shores 

 here and there in all the Areas ; similarly does B. pallens, Swartz. 

 At Burntisland Reservoir in July, a curious form of the last mentioned 

 was very abundant on the clayey bottom in water to a depth of about 

 18 inches. Returning in October for more of it for Mr H. N. Dixon, not 

 a trace could be found, owing to the water level of the reservoir having 

 fallen greatly through drought. Respecting this plant Mr Dixon 

 wrote as follows : — " Mr Nicholson, to whom I sent the Burntisland 

 Reservoir Bryum, agrees with me that while, at first sight, it resembles 

 B. neodamense, Itzigs., it is really an altered form of Bryum pallens, 

 Swartz." 



Mnium punctatum, L. IV. Frequently abundant on wet, somewhat 

 sandy shores and in bogs ; also in the other Areas, but not plentiful 

 at the lochs. 



FONTINALACE^. 



Fontinalis antipyretica, L. " I., II.," IV., V., VI., VII. Abundant in 



many places. I have not dredged it from a greater depth than 10 



feet in any of the four last Areas. In V. and VII. it is less 



common than elsewhei-e. 

 Fontinalis squamosa, L. IV., VI. Sometimes plentiful, but not a 



common moss in the lochs, 



HOOKERIACE^. 



Pterygophyllum lucens, Brid. IV. Abundant about the wet shores of 

 the hill lochs, mostly on the soil.
