a more concise account of the birds observed on the coast 

 of CO. Dublin. Among the sliortcr^ but by no means less 

 important notices, Mr. R. Warren supplies some interesting 

 information respecting the spring-migration of Motacilla 

 alba along Killala Bay, in the west ; and Mr. R. J. Ussher 

 describes a large colony of Cormorants [Phalacrocorax curbo) 

 breeding on trees on an island in a lonely lake in tlic Mayo

 Among the especial rarities for Ireland, occurrences of the 

 Rose-coloured Pastor, Golden Oriole, Night-Heron, Wood- 

 Sandpiper, and ^lontagu's Harrier may be mentioned, and 

 these records indicate an increased interest in tlie avifauna

19. Jachon's ' Thousand Days in the Arctic' 



[A Thousand Days in the Arctic. Ry Frederick G. Jackson. Two 

 vols. London and New York : Harper Brothers, 1899.]

 the history of his thousand days in Franz-Josef Land, con- 

 tain numerous references to birds, especially to those which

 Appendix to the present work, contained in Mr. Jackson's 

 own field-notco on the birds met with during the stay in 

 Franz Josef Land, and in an article on the eggs collected, 

 prepared by Mr. F. W. Frohawk.
