botanists, geologists, zoologists, and archaeologists were soon hard 

 at work on what was comparatively new ground to many. So far 

 back' as 1865 the Club collected worked flints from the- thick- 

 bedded accumulations of gravels that occur on the shores of 

 Lough Neagh at and around Derryadd Bay, where a considerable 

 number of specimens were again found during the present visit. 



The district visited did not prove very rich in bird life, but 

 the ornithologists of the party reported having noted thirty-two 

 species about the shore of Derryadd Bay. Of these, the most 

 interesting was the yellow wagtail, Motacilla rait. This migratory 

 species nests in considerable numbers around Lough Neagh, as 

 well as near some of the large Connaught lakes, but is unknown 

 elsewhere in Ireland. The Grasshopper-Warbler, Locustella ncevia, 

 was also noted near the lake in Lurgan Demesne. 



The conchologists found the dry weather conditions most 

 unfavourable for collecting land-shells, but, along the lake shore, 

 nice specimens of Succinea elegans were abundant in certain damp 

 muddy spots, where it was feeding in company with a fresh-water 

 species — Limncea palustris. The latter was the short malleated 

 and obese form for which Lough Neagh is noted. Several 

 Planorbis carinatus were also collected — that curious non-typical 

 form found in Lough Neagh and Lough Beg and the canals 

 and rivers connected with both. This is the form so puzzling 

 to English conchologists, who often confuse it with P. 

 marginatus. Well-known authorities consider that our Irish 

 specimens belong to a more primitive race than the British forms, 

 where the separation between the two species is very well defined. 

 Some Pisidia were collected for future examination. 



A copious supply of Volvox giobator was noted, also a number 

 of varieties of water-fleas and cyclops. 



Several interesting plants were noted by the botanists of the 

 party, the following being the more important : — Ranunculus 

 circinatus, Thalictrum flavum, Nasturtium palustre, Myriophyilum
