Dr. E F. Scharff, A. G. Tansley, and K. Lloyd Praeger (Secretary)), the Eoyal 

 Society of London, and the Eoyal Dublin Society, helped materially to defray 

 the cost of the Survey, and, in the case of the Eoyal Society, the cost of 

 publication. 



A brief account of the field-work is now given. 



Narrative of the Field-work. 

 1909. ' 



The field-work opened at Easter, when a party of seven, namely 

 Major Barrett- Hamilton (Mammals), J. Bayley Butler (Protozoa), A. D. 

 Cotton (Marine Algae), Arthur Skinner (Photography, &c), A. W. Stelfox 

 (Mollusca), Isaac Swain (Geology), and R. LI. Praeger (Phanerogams), spent 

 five to eight days upon the island. In the groups of Seaweeds and Terrestrial 

 Mollusks especially good progress was made not only on the island, but 

 subsequently on the mainland adjoining. H. Bassett and W. L. Hicks, both 

 of Liverpool University, members of a cave-exploring party who had been 

 working at Cong, joined the party before the week was out, and reinforced 

 the photographic detachment. 



The May party was small, consisting of Nevin H. Foster (Birds), 

 Eev. Canon Lett (Mosses and Liverworts), E. Southern (Worms), and the 

 writer. In all the groups mentioned good lists and collections were made 

 on the island, and subsequently in the surrounding district, where Canon Lett 

 worked Achill and Curraun, and Mr. Foster the Louisburgh area ; while the 

 welcome arrival of the Fisheries steamer " Helga " gave Mr. Southern an 

 opportunity of dredging in the local waters in company with G. P. Farran, 

 S. W. Kemp, and W. M. Tattersall, who were on board ; the result being 

 considerable collections of marine animals. Great progress was made during 

 May with the Mosses and Liverworts, as Canon Lett was reinforced by 

 W. H. Pearson from Manchester and the Eev. C. H. Waddell from Co. Down, 

 and among them much exploration was carried out. 



Early in June a party of ten went to the island, including J. N. Halbert 

 (Insects, &c), W. F. de V. Kane (Lepidoptera, &c), C. F. Eousselet (Eotifera), 

 D.J. Scourfield (Entomostraca), E. F. Scharff' (Mollusca, Woodlice, &c), and 

 E. LI. Praeger. As regards insects, the prevalence of cloud and wind during 

 the visit caused very little to be on the wing, Lepidoptera being especially 

 few ; but good collections of beetles, &c, were made. On leaving the island 

 after a five days' sojourn, the majority of the party worked the Achill Sound 

 district.
