Clare Island Survey — General Introduction and Narrative. 1 9 



geological survey of the area, Newell Arber spent several days in June 

 collecting Carboniferous fossils from the sandstones of the north-eastern part 

 of the island. During the same month C. J. Patten again visited Clare 

 Island in pursuance of his study of the Birds ; and W. West paid a second 

 visit of ten days' duration to complete his work on the fresh-water Algae. 



A double party was arranged in July. On the 12th of that month Miss 

 Stephens (Sponges), J. de W. Hindi (Glacial fossils), E. LI. Praeger, and 

 others went to the island. Advantage was taken of exceptionally calm weather 

 to land and collect on Mweelaun, an isolated rock lying two miles south of 

 Clare Island. This first party was followed five days later by a larger con- 

 tingent, including E. J. TJssher and Pastor Lindner (Birds), W. P. de V. Kane 

 (Lepidoptera), T. J. Westropp and the late Dr. G. Fogerty (Archaeology) 

 Professor G. H. Carpenter (Aptera), J. 8. Dunkerly (Infusoria and Flagellata), 

 A. W. Stelfox (Land and Fresh-water Mollusca), G. 0. Sherrard (Nematodes), 

 and Professor Gwynne Vaughan (Botany) ; several of these had previously 

 done some days' work on Achill. The break-up of the party was gradual, 

 and while Kane, Dunkerly, Hinch, and Gwynne Vaughan subsequently 

 worked at Louisburgh or Achill, Westropp, Fogerty, Stelfox, and Praeger 

 sailed on to Caher Island, Inishturk, and Inishbofin (and Ussher and Lindner 

 ■to the latter two), for the purpose of completing their survey by studying 

 the insular areas adjoining the immediate scene of the main work ; results of 

 very considerable interest were obtained. In the meantime J. N. Halbert 

 was collecting insects at Louisburgh, where he was joined by P. H. Grimshaw 

 (Diptera), and a very good fortnight's work was carried out in that area. 



On August HE. Heron-Allen and Arthur Earland arrived at Mulranny 

 for the purpose of collecting Foraminifera. A. D. Cotton at the same time 

 paid his final visit for Marine Algae, working first at Achill Sound, and 

 subsequently on the island. The SS. " Helga," with G. P. Farran and 

 E. Southern on board, came in, and dredging was carried on for some days. 

 After the departure of the steamer further work was done, and the search 

 for Foraminifera was extended as far south as the famous deposit of Dog's 

 Bay near Eoundstone. 



The especially low spring tides of September were utilized by A. E. 

 Nichols fPolyzoa) and N. Colgan (Mollusca) for collecting at Louisburgh, 

 while Miss Stephens (Sponges) and Miss Knowles (Lichens) worked during 

 the same period with the " Helga " staff at Blacksod ; but tempestuous 

 weather interfered to some extent with their researches. 



During the same month D. K. Pack-Beresford spent a week working at 

 the Spiders of the district lying between Clew Bay and Killary Harbour. 



At the beginning of October Mr. and Mrs. Carleton Lea (Fungi), and
