After a bibliography of the Trinidad avifauna Mr. Chap- 

 man proceeds to tell us of liis own experiences. During his 

 sojourn he identified 136 land-birds and 15 water-birds, 

 together 151, of which 5 were new to the ornis of Trinidad, 

 and 2 of these [Chlorospingus leotaudi and Basileuterus vermi- 

 vorus olivascens) are described as new to science. Mr. Chap- 

 man's general remarks on Trinidad bird-life which follow are 

 of great interest. Few North-American migrants visit the 

 island, except 4 species uf Ducks, a Rail, and 29 Waders and 

 Water-birds. In all, there are only 10 land-birds that occur 

 on migration. We have also remarks on songs, nesting, 

 and colours, which will attract the general reader. 



The list of Trinidad birds which concludes this useful 

 memoir enumerates 306 species. It is based mainly on the 

 author's own observations and those of Leotaud and Taylor 

 (' Ibis,' 1864, p. 73). Leotaud's collection has been pre- 

 served, and is on view at the Victoria Institute, Port of Spain, 

 where Mr. Chapman made a careful examination of it. 



52. Clarke on the Persecution of the Great Skua. 



[The Persecution of the Great Skua {Stercorarius catarrhactes). By 

 Wm. Eagle Clarke, F.L.8. Ann. Scottish Nat. Hist. 1894, p. 8.] 



Mr. Eagle Clarke calls attention to the bad treatment of 

 the Great Skua during the past three years. In 1890 and 

 1891 the Foula colony, now the largest in Europe, suffered 

 so severely through egg-taking that practically no young 

 birds were produced. In 1893 matters appear to have been 

 little better. As regards the Fseroes, Col. Feilden gives the 

 results of his observations, and comes to the conclusion that 

 the ultimate extinction of the Great Skua as a breeding- bird 

 in these islands cannot long be delayed.
