CONTRIBUTIONS TO THE 

 NATURAL HISTORY OF LAMBAY. 



[Communicated to the Dublin Naturalists' Field Club, Feb. 12, 1907.] 



PREFACE. 



BY R. LLOYD PRAEGER. 



Shortly after the present owner entered into possession of 

 Lambay, I ventured to suggest to him that a systematic 

 examination of the fauna and flora might lead to important 

 scientific results, and moreover add to the interest which he 

 already felt in the native inhabitants — animal and vegetable— 

 of the island. Mr. Baring accepted the suggestion at once. 

 Workers in the various branches of natural history were 

 enlisted, and the survey was begun in June, 1905, when a week 

 of cloudless weather favoured our first invasion. The party 

 on this occasion consisted of H. J. Seymour (Geology), 

 R. Patterson (Birds), Dr. Scharff (Land Mollusca, &c), A. W. 

 Stelfox (Land Mollusca), W. F. de V. Kane (Lepidoptera), 

 J. N. Halbert (other Insecta), W. Rankin (Marine Crustacea), 

 D. M'Ardle (Cryptogams), R. LI. Praeger (Phanerogams), 

 and G. E. Low (photography). Later in the same year various 

 members of the party revisited Lambay and continued their 

 work. At Easter, 1906, another joint visit was made, and the 

 marine fauna and flora especially were collected, the party 

 consisting of N. Colgan (Marine Mollusca), A. R. Nichols 

 (Polyzoa, Echinodermata, &c), H. J. Buchanan-Wollaston 

 (Hydrozoa, &c), A. L- Batters (Algae;, with J. de W. Hinch 

 (Glacial Geology), N. H. Foster (Birds), R. Patterson, 

 W. Rankin, and R. LI- Praeger. In June of the same year a
