40 The Irish Naturalist. February^ 



(Fungi), A. D. Cotton and Dr. F. Borgesen of Copenhagen 

 (Marine Algae), F. J. Lewis (Peat deposits), R. LI. Praeger, 

 and several others. While most of the party returned at 

 the end of a week, A. D, Cotton worked on at Louisburgh 

 and Achill till May 15. 



On May 29 Rev. W. F. Johnson and Mrs. Johnson went 

 down, and spent a month, mainly on the island, collecting 

 insects. In connection with the 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. Hinch 

 (Glacial fossils), R. LI. Praeger, and others went to the 

 island. Advantage was taken of exceptionally calm weather 

 to land and collect on Mw^eelaun, an isolated rock lying 

 two miles south of Clare Island. This first party was 

 followed five days later by a larger contingent, including 

 R. J. Ussher and Pastor Lindner (Birds), W. F. de V. Kane 

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

 (Archaeology), Professor G, H. Carpenter (Aptera), J. S. 

 Dunkerly (Infusoria and Flagellata), A. W, Stelfox (Land 

 and Fresh-water Mollusca), G. O. Sherrard (Nematodes), 

 and Professor Gwymne 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 IJssher 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 Louis- 

 burgh, where he was joined by P. H. Grimshaw (Diptera), 

 and a very good fortnight's work was carried out in that 

 area.
