nests being placed in the tops of tall beech trees. The many large 

 lakes are doubtless well stocked with water-frequenting birds, but 

 time did not permit their exploration. Several Mute Swans were 

 noted, some of them being accompanied by their broods, but of 

 the Ducks only the Mallard and Pochard were observed. Every 

 lake visited was tenanted by one or more pairs of Great-crested 

 Grebes, and the Little Grebe was also very common. 



Among the Grustaceans the following were obtained : — The 

 Amphipod Gammarus pulex, and the fresh-water Isopod Asellus 

 aouaticus, both of these being found commonly in the lakes and 

 streams. Previous to their visit only the four common species of 

 Woodlice — Trichoniscus pusillus, Philoscia muscorum, Oniscus 

 asellus, and Porcellio scaber — were recorded from County Cavan, 

 and to these they were enabled to add four, viz., Trichoniscus 

 roseus, T. pygmceus, Porcellio pictus, and Metoponorthus pruinosus. 

 Of these two must be regarded as introduced species — T. roseus 

 and M. pruinosus — having been found only in a greenhouse. 



Mr. Balfour Browne reported the capture of Dytiscus circum- 

 cinctus by Mr. Welch near Drumlane. Hitherto this species had, 

 in Ireland, only been taken in Armagh, but during the past Summer 

 it has been taken by the speaker near Moira, County Down. 



Mr. A. W. Stelfox described the Land and Fresh-water Shells 

 which were found during the July excursion, and compared the 

 list with one compiled in the mountainous part of the county on 

 a previous occasion. Five species proved to be new records for 

 Cavan, of which the most interesting were Acanthinula lamellata, 

 Hygromia fusca, Arianta arbustorum, and Acroloxus lacustris. 



The Spiders and Harvestmen were submitted to Mr. D. R. 

 Pack Beresford, who reports : — 



" Most of the Spiders sent me were unfortunately immature, 

 and many were therefore impossible to identify. I found however 

 seven species : — Tegenaria derhamii Scop., Labulla Uwracica VVid., 

 Meta segmentate: CI., M. meriance Latr., Lvcosa turicola De Geer, 

 Pardosa pullata CI., and P. amentata CI. Of these only
