and sandstones of the Old Red Sandstone. The only excep- 

 tion to this was in the immediate neighbourhood of Cork city, 

 where the Carboniferous limestone forms the valley of the 

 Lee. Suitable habitats for characteristic northern species we 

 found more plentiful than we would have expected in a 

 highly cultivated southern county such as Cork, but the 

 rough woods along the Blackwater near Youghal, at Lough 

 Allua, and especially those facing north across the north inlet 

 at Rostellan demesne, provided just the ground that Helix 

 lameltata, H fusca, Hy. excavata, and Acme li?ieata are usually 

 found on. Some small species from these woods, which 

 would otherwise have escaped observation in a hurried visit, 

 were collected by Mr. Standen — to whom we owe our best 

 thanks — from moss shakings. This method of collecting is 

 indispensable where a quick survey of the ground is required. 

 One of our main objects was to study the larger Hyaliniae, as 

 so much confusion has arisen through mistakes in the identi- 

 fication; in the British Isles generally, of Hy. drapamazidi, 

 Hy. glabra^ and Hy. helvetica ; and in Ireland between the first 

 mentioned and the large forms of Hy. cellaria. Like the 

 former Conference weeks, the weather during this was all 

 against the collector of mollusca, being hot and dry most of 

 the time. Owing to this, all chance of finding Geomalacus in 

 the west of the count}' was hopeless. This was a great 

 disappointment to us, as at Inchigeela and Lough Allua there 

 were large areas of rocky habitats, in no way differing from 

 those in which the slug is usually found, except, of course, 

 that they are further from the sea. Thanks to Messrs. Taylor 

 and Standen many doubtful points that arose during the 

 collecting were settled on the spot, while Mr. Roebuck's 

 experience in the identification of the slugs and their varieties 

 was most valuable, enabling the daily lists to be completed in 

 the field. As Messrs. Taylor and Roebuck found collecting 

 in Ireland so different from that they were accustomed to in 

 England, we thought that it would add greatly to the interest 

 of the report if they would give us a few notes on the subject, 

 which they have kindly done as follows : —

 favoured during the excursions with suitable climatological
