* Diphyscium foliosum. Linn. 
Very rare. Slievenamaddy Mountain. — Rev. H. W. Lett. This moss, 
so rare in Ireland, has been found also on Anglesey Mountain, Louth, just 
outside our district, by Rev. C. H. Waddell. 
Zygodon rupestris. Schp.

of the Bridge on the Larne road, at Kilroot ; sparingly on rocks in Rathlin 
Island (Antrim). — S. A. S.

Co. Antrim. — S. A. S. 
* Orthotrichum calvescens. Wils. 
Very rare. Two tufts of this moss were collected in the district— I 
believo in Glenshesk, County Antrim — but as the label has been lost, this 
species cannot be localised with entire certainty, — S. A. S.

diately above Drum Bridge (County Down). This moss is plentiful in this, 
its only Irish station, where it was discovered by Mr. J. H. Davies, of Glen- 
more, in 1878.
