P. S. — It is somewhat remarkable, that, live months after I had an- 

 nounced the occurrence of this bat in Gal way to Drs. Harvey and Kina- 

 han, the latter gentleman should have had the opportunity of recording 

 its occurrence at Ennis, where it appears to be rather common, Mr. F. J.

 commoner species of Lichens, since these plants have been examined 

 by the aid of powerful microscopes, I have thought it better to include 

 all those species which have come under my own observation. The 

 synonyms quoted from examination of authentic specimens are distin- 

 guished by a note of admiration. I have to thank Mr. Moore and Rear- 

 Admiral Jones for the kindness with which they have allowed me to in- 

 spect their collections.
