Notes on some Mosses from the Three Lothians. 

 By James M'Andrew, 



Assoc, of the Botanical Society of Edinburgh. 



Perhaps the following notes may prove interesting to local 

 and Scottish bryologists. They consist principally of new 

 records of British mosses gathered in the Lothians since the 

 " Census Catalogue of British Mosses " was published in 

 1907. I am indebted to Mr. William Evans, Edinburgh, 

 for about one-half of them ; the others were gathered by 

 myself and from time to time reported to Mr. R. H. 

 Meldrum, and will no doubt in due course appear in the 

 next edition of the "Census Catalogue."
