I904- M'Ardle. — Sligo Confcre7tce, Bryophyta. 209 



The uumber of Mosses collected is 84. Mauy of them are rare, such 

 as Hypmim irrigimin, Aniblysteginin confenmdes^ &c. ; aud the appended list, 

 though provisional only, may be taken as the fullest account we possess 

 of the Mosses from the Counties of Sligo and Leitrim. 



The identification of these plants involves a considerable amount of 

 microscopic work, which takes time to accomplish ; and I should not 

 have been able to present both lists for this number of the Irish 

 Naturalist were it not for the kind assistance given to me by the Rev. 

 Canon Lett, to whom I offer my best thanks. 



All the stations belong to Co. Sligo, except those in Glencar, which are 

 in Co. Leitrim.
