Birds' Eygs in the British Museum. 515 



P. 80. The statement that " the eggs of all Pigeons are 

 Avhite when first laid and that discoloration takes place 

 after incubation has commenced " is not borne out by- 

 facts. Perfectly fresh eggs of GEiia cnpensis are a 

 brownish cream-colonr. 



P. 141. The egg of Colymbus pacificKS is figured on pi. xi. 

 fig. 6, and not fig. 5 as stated (see also pp. 149 and 

 250). 



P. 147. Procellaria pehiyica L. Four eggs from the Blasket 

 Isles are said to have been taken on April 26. Mr. W. 

 H. Turle^ who took the eggs in question, writes in the 

 'Ibis,' 1891, p. 11, that he obtained a good many eggs 

 on Irishnabro in the Blasket group in the last week of 

 May. No Storm-Petrel has eggs as early as April in 

 the British Isles. The eggs are marked in pencil 

 4/2G/89, but Turle's set-marks are rarely intelligible. 



P. 186. Sterna dongalli Mont. Three eggs ascribed to this 

 species from Glashedy, Ireland (H. Saunders), and 

 probably all, or nearly all, the eggs of American 

 origin in the Museum, are not those of the Roseate 

 Tern at all. Two eggs from the Crowley bequest are 

 also very dubious. Those from Wales and the Farncs 

 are, however, genuine. The statement that '' the eggs 

 of the Roseate Tern resemble those of the Common 

 and Arctic Terns and pass through the same variations 

 of shape and colour" is quite erroneous, and is founded 

 on unreliable material. 



P. 187. *S^. cantiaca Gm. Six eggs from Lake Since are 

 said to have been taken on May 9, but Seebohm's 

 visit to that locality was paid on 9 June, 1883, and 

 the eggs are marked with that date. 



P. 220. Larus glaucus Fab. Under this heading is cata- 

 logued a series of erythristic eggs of the Herring-Gull, 

 L^ argentatus, taken at Vardo by Nordvi (fi'om the 

 Seebohm collection). They were ascribed to L. glaucus 

 by Seebohm and figured by him as such, but it has 

 been clearly shown by the late II. J. Pearson and 

 others that the species which prodaces these red eggs
