Lett — On the Mosses of the Mourne Mountain District. 301 
Thuidium recognitum, Hedw. 
Anglesey Mountain, near Omeatli : H. "W. L. Yery rare, and 
not hitherto recorded from Ireland. This moss is described 
as growing " on limestone rocks and chalk hills " ; but there 
are neither where I got this, and the nearest lime to the spot 
is some five miles distant, at the Carlingford quarries. Mr. 
Gr. A. Holt decided that this is unmistakably the plant 
collected by me.
