cairn on the summit, we commenced our descent to the 

 " shelter stone " at the head of Loch Avon, passing on our 

 way over a large field of snow. Amongst other hepatics 

 were found Pleurodada albescens, Jamesoniella Carringtoni, 

 Jung, saxicola (the second record for British Isles), and 

 Marsupella Stdbleri (its first record for Scotland). Climbing 

 out, we took the nearest route to the Derry, and thence 

 to Danzig Shiel, which we reached about midnight. 

 Similarly in 1894, another day was spent in going to 

 Glass Maol. 



The portion of the county more particularly examined 

 is bounded on the south, roughly speaking, by a line from 

 the summit of Lochnagar, along White Mountain to Loch 

 Phadruig, and on the north from Lion's Face down the 

 river Dee to Balmoral Castle. 



In explanation of the long period elapsing between the 

 collection of the specimens and the completion of this 

 paper, I may say that it has been chiefly owing to eye 

 troubles on the part of myself. Most of the specimens 

 were examined and determined long ago, but a few 

 remained for reconsideration. This I was unable to 

 carry out. Through the kind and efficient help of Mr. 

 Symers M. Macvicar, the now eminent Scottish Hepati- 

 cologist, the examination has been completed, and I here 

 acknowledge my indebtedness, and thank him not only 

 for this, but for drawing up the list from the specimens,, 

 and thus making the publication of it possible. 



A glance at Mr. Macvicar's published list of the 

 Hepaticce of West Inverness and at the following list of 

 Balmoral He/paticoi will show considerable differences, 

 although the two localities are in nearly the same latitude. 

 These differences in the main are no doubt attributable 

 to differences of altitude and distance from the sea, and 

 the consequent difference of temperature. There are, no 

 doubt, other less important factors. The only Plagiochila 

 I found was P. asplenioidcs. P. spinuliosa is reported 

 rare. To me one of the most striking facts was the 

 scarcity of Lejeunece, only L. serpyllijolia being found, 

 and that not plentiful. In this elevated district I found 

 no Frullania dilatata, and the genus Porclla was very 

 poorly represented. The rarely fruiting Blcpliarozia ciliaris
