198 NATURAL HISTORY SOCIETY OF DUBLIN. 



BTymenophyUum Tunlridgense. — At a former meeting of the Society 

 I recorded the occurrence of this Tern on conglomerate rocks in the 

 neighbourhood of Longford. I have since searched similar places, ap- 

 parently well suited for its growth, hut without success. It grows in 

 the greatest luxuriance in the gneissose hills, on the south side of 

 Lough Grill, near Sligo, so that it is not improbable that the plants of 

 the Longford station may be a waif from Sligo. 



Asplenium ruta-muraria, var. attenuata. — I also recorded at a former 

 meeting the occurrence of a well-marked variety of A. r. muraria, on a 

 wall near Athlone.* 



Botrychium lunaria By no means common in the midland coun- 

 ties. I met with it on an esker, a few miles north-east of Athlone. 

 Some years ago I saw plants gathered at Doon, King's County. 



Ophioglossum vulgatum Yery abundant in pastures all through 



these counties. 



LYCOPODIACE-S!. 



Lycopodium selago. — Common in all the bogs. 



L. selaginoides. — Very abundant on the shingly shores of the "West- 

 meath Lakes, particularly Lough Ennel ; on the mossy slopes of the 

 canal cuttings near Mullingar. 



Isoetes lacustris. — Abundant in the shallow waters near the edges 

 of all the lakes. 



I have not gone into the Algae, but I could not help observing the 

 following — 



JYostoc commune. — In abundance in the hollows of limestone rocks 

 in the county of Roscommon. 



Chcetophora endiviafolia. — In wet crevices of the rocks, and at the 

 edges of springs and streams in the same county. 



Batrachospermum moniliforme. — Yery abundant in the River Suck, 

 near Ballinasloe, and in the same neighbourhood. 



B. vagans. — Plentiful in Cloghan Lough, a bog pool on the east side 

 of the River Suck, near Ballygar, county of Galway. 



Mr. Foot's paper was illustrated by dried specimens of some of the 

 rarer of the plants mentioned in the foregoing list. 



Dr. Moore said, he considered the paper just read a very appropriate 

 one for the Natural History Society of Dublin. Although to the ex- 

 perienced botanist the plants noticed might not at first seem to possess 

 much interest, judging from their comparative rarity in Ireland, they 

 were important in a distributive point of view, their habitats being in 

 the midland counties, which were less known to naturalists than the 

 seaboard counties. He had some experience of this fact lately, when 

 endeavouring to collect data for a small work about to be published on 

 the distribution of the Irish plants. He and the gentleman with whom
