180 COLLIER AND STANDEN: 
On Monday, the 15th, the party started promptly at 6 a.m. 
on board the ‘‘ Duras,” bound for Aranmore, the largest of 
the Aran Islands, the prospect of visiting which had been one of 
our greatest inducements to join the trip. These islands, which 
are celebrated as being the locality for the largest British 
specimens of “7. zemoralis, and also as one of the localities for 
Vertigo Moulinstana, are the remnant of a great sea-shelf of car- 
boniferous limestone, with precipitous cliffs on the Atlantic side 
200—300 feet in height, and a series of terraces sloping down to 
the water on the other. They are extremely barren, and ina dry 
season there is very little vegetation. The cracks in the 
mountain limestone, however, are filled with beautiful ferns and 
other plants, and are the favourite resort of the larger He/zces. 
Towards the eastern end of the island of Aranmore is Killeany 
Bay, where there is a considerable extent of sub-aerial sands, 
which are the resort of many land shells, numbers of which are 
buried by the shifting sands during gales of wind. At times 
also on the sea-board at low water, thousands of marine shells 
are blown up amongst them, We found, to our great dis- 
appointment, that time would not allow of a visit to the locality 
for V. Moulinsiana, which is a low swampy ground at the 
extreme western end of the island, about three miles from our 
landing place, Portmurvey, and our course lay in the opposite 
direction. After visiting the wonderful old pre-historic fort of 
Dun A‘ngus—the finest structure of its kind in Europe—we 
made our way across the island towards Kilronan. The intense 
heat of the day, and consequent dryness of everything, prevented 
our finding much of interest in the way of shells, with the excep- 
tion of Hyalinia Draparnaldi. In a low swamp near Dun 
Oghill a few specimens of Péstd/um milium occurred, and this 
locality was carefully searched for specimens of Vertigo, but 
unsuccessfully. Well on in the afternoon, and just as we began 
to despair of finding anything worth having, a welcome shower 
came on, and we lost no time in making our way towards 
Killeany. The heavy rain acted like magic, and we found He/rx
