Bibliography. 



In view of the publication by Mr. Adams in a recent volume of these "Proceedings " 

 of a full bibliography of Irish Lichens, as an addendum to his paper on "The 

 Distribution of Lichens in Ireland " (vol. xxxvii, Sect. B, No. 10, 1909), a list of the 

 papers dealing with the Lichens of this district appears superfluous. No important 

 paper has appeared since the date of Mr. Adams's list.
