Mr. Nevin H. Foster, speaking with regard to Terrestrial 

 Isopods (Woodlice), stated that our four commonest species were 

 also found in eastern North America, while Philoscia conchii, 

 Metoponorthus melanurus and Elutna purpurascens occurred in 

 Madeira, Pyrenees, and also in Ireland, where they must be 

 regarded as Lusitanian species. 



Mr. Praeger replied briefly as follows : — 



To Mr. Oldham — There were plenty of circumpolar species 

 of flowering plants, but only three or four confined to eastern

To Mr. Smith — He was not certain in his own mind as to 

 the date of the Lusitanian flora. 



To Mr. Beeston — He regarded the absence of the Irish 

 Heaths from Cornwall as merely chance, and pointed out that 

 the Irish Spurge, Euphorbia kiberna, was found in Cornwall and 

 Devon as well as in the south and west of Ireland and S.W. 

 Europe.

 THE GIANT'S CAUSEWAY. 



Immediately after breakfast the party left in brakes for 

 Portmoon, the extreme eastern point of the Causeway. From this 

 delightful spot the members were conducted on foot along the 

 cliffs, passing over the summit of Contham Head, Bengore Head, 

 Benbane Head and Pleaskin, to the Hawk's Hollow, where the 

 first glimpse of the Grand Causeway was obtained. Glorious 

 sunshine favoured the party, and many halts were called during 

 the walk, so that the members might enjoy the views of bays and 

 headlands, and study the geological formation of the great basaltic 

 cliffs. While on Bengore Head the ornithologists had the pleasure 

 of watching a flying exhibition given by a family party of Ravens,
