COLLIER ! EXCURSION TO THE WEST OF IRELAND. 43 
Clausilia perversa Pult.—Common on walls. 
Succinea elegans Risso. var. ochracea Betta.—Plentiful in 
one very damp field on flags and rushes that had been cut 
down. 
Only a very short list, but we only collected on one day, 
and had no opportunity of getting any freshwater species, as we 
were here such a very short time. 
On leaving Galway, we took the steamer across the bay to 
Ballyvaughan in County Clare, which was really the locality we 
had come to visit, as I had seen some very fine Helix nemoralts 
from there collected many years ago by my friend Mr. Thomas 
Rogers. This northern part of County Clare is all on the lime- 
stone, with hills rising to a height of over 1,000 feet, very often 
in terraces of the limestone pavement—a very paradise for ferns

Helix rotundata Miill. Very scarce. 
H. rupestris Drap. Everywhere; on rocks and walls, and 
generally very fine. 
H. pulchella Mull. ‘Two specimens only. 
H. aspersa Mill. Very abundant, and a good size, but not 
very thick shells, In some of the little meadows this 
species and /. z¢a/a were so common that one could not 
step without crushing them by dozens as one walked 
across. 
H. nemoralis L. ‘The shell fav excellence of this district. 
Very fine and very variable. ‘The first two days at Bally- 
vaughan were very wet, and although we went out whenever 
practicable we could not find any, as they do not seem to 
crawl out during very heavy rain. When we found the
