296 The Irish Naturalist. November, 



The Gobbins Caves. — IVlessrs. Scharff and Ussher, on 

 behalf of the Irish Cave Fauna Committee, with Dr. Haddon 

 and a few friends, took advantage of the off-day to visit, under 

 R. Welch's guidance, the cave from which so many bones of 

 mammals, birds, and fish, have recentl}^ been obtained b}^ Mr. 

 B. D. Wise, who joined the party, and kindly acted as host for 

 the da3^ The cave was carefully examined by the party, and 

 a report will be made later. Another cave which may also 

 yield good results was examined, and some of the Seven 

 Sisters Caves, which were entered from a boat. The party 

 returned along the undercliff Cretaceous sections, and visited 

 several of the curious Chalk rocks ^^xiordX^dihy Helix aspersa 

 and H. nemoralis. 



RosTREVOR AND Cari^ingeord (Sept. 13 and 14). — This 

 excursion, w^hich was limited solely to those professionally or 

 otherwise intimately associated with the science of geology, 

 was arranged originally to give Professor Sollas the oppor- 

 tunity of explaining personally the geology of Barnavave. In 

 his unavoidable absence, the conducting of the party was 

 undertaken by H. J. Se3^mour. A party of nineteen left 

 the G. N. Terminus, Belfast, on Saturday afternoon, for 

 Warrenpoint. Trams were taken to Rostrevor, where the first 

 halt was made at the so-called green granite quarry behind 

 the Mourne Hotel. The party then proceeded to the Clough- 

 more, and from this point, the chief characteristics of the 

 geology of the surrounding district were briefly indicated. 



Proceeding round the flanks of the mountains in a southerly 

 direction, the party descended to the shore near Killowen, 

 where they examined and obtained specimens of the lampro- 

 phyre dyke which occurs there. The modes of occurrence 

 of these dykes, which are post-Silurian, and of the basalts 

 which are post-Carboniferous were contrasted and explained. 

 A short walk brought all back to Warrenpoint, whence they 

 proceeded to Greenore Hotel, via Omeath. 



The next morning an early start was made, and the party 

 proceeded to walk across the low-lying flat tract of country, 

 the so-called 25-foot raised beach, arriving shortly at the 

 gently undulating ground of Carboniferous limestone form- 

 ing the foot hills of the great igneous complex composing the 

 Carlingford Mountains. Several limestone quarries were 

 visited, and the dykes and sills of basalt traversing the
