Nardia emarginata, Gr. and Benn. ( = Marsupella emarginata, Bum.). 
“ I.,” IV. On wet rocks and shores of hill lochs, and often in the 
water ; rather less abundant than the last mentioned. 
Nardia scalaris, Gr. and Benn. IV. On wet sandy-peaty shores of hill 
lochs, often abundant. 
The following species are frequently found covering wet places about 
lochs, particularly on shady banks, under rocks, etc., in all the Areas, 
but especially in IV. : — Pellia calycina ( Tayl .), P. epiphylla, Lindb., 
Conocephalus conicus, Bum., and Marchantia polymorpha, L. The last 
mentioned is often found in the water of hogs as well as in drier places. 
Several species of Jungermannia are met with on the shores of the 
more elevated lochs, hut always in small quantities. 
Amongst the mountains of Area IV. many lochs are bordered 
more or less by rocks which are frequently covered in a most prolific 
manner with masses of lichens. A description of the flora of these 
lochs would be incomplete were it not, under such circumstances, to 
notice the most predominant and conspicuous species of these lichens. 
They are as follows : — Platysma glaucum, Nyl., Cetraria aculeata, 
Ft., C. muricata, Ach., Parmelia lanata, Wallr., P. omphalodes, L., 
Alectoria jubata, Nyl., Lecanora tartarea, Ach., Sphserophoron 
coralloides, Pers., Lecidea geographica, Schcer. (p. 101).

A few very abundant species that were noticed : — 
Batrachospermum moniliforme, Roth. “ I.,” IV. Abundant; very scarce 
in the other Areas. 
Batrachospermum vagum, Roth. I. Scarce. IV., VI. Frequent; very 
scarce in the other Areas. 
Enteromorpha intestinalis, Link. “ III.,” V., VII. Particularly plentiful 
in Kilconquhar Loch and Loch Fitty. 
Ulothrix sequalis, Kutz., and its var. catseniformis, Rabenh. In all the 
Areas, but particularly in IV. 
Cladophora fracta, Kutz. “ II.,” VII. Occasionally very abundant. 
Cladophora crispata, Roth. VII. Occasionally abundant. 
Cladophora flavescens, Ag. V., VII. Sometimes very abundant in 
lochs that receive the drainage of villages. 
Cladophora canalicularis, Roth. VI., VII. Abundant; less so in the 
other Areas. It covers stones and rocks about the shores of lochs 
that receive the drainage of villages, farms, and cultivated land. 
It is often covered with a prodigious quantity of diatoms, chiefly
