It was my original intention to examine only the mosses and 
lichens, but the latter proving to be few in number, I thought it better 
to add the hepatics than to reserve them for a separate Eeport. 
I may mention that the lichenologists who may visit the Mourne 
Mountains will be disappointed with the collections of lichens to be 
made on them. Many of the tops are sub-alpine, and various species 
which should be expected and were looked out for by myself, are 
remarkable for their absence, whilst even the most common sorts 
usually found in such places are scarce and poor. I say this, though 
aware that I may have overlooked many that will hereafter reward 
other investigators. 
!N'or do I think that, often as I have visited the breezy tops, or 
grubbed in the damp glens, or peered along the lonely rocks and bleak 
slopes of the Mournes, I have exhausted the stores of hepatics and 
mosses indigenous to the district.
