I then applied to the late Prof. Alfred Newton, who edited 

 Wolley's notes, but he could not throw any lij;ht on the 

 subject ; and after a good deal of barren searching in the 

 pages of likely literature, I could only come to the conclu- 

 sion that Wolley had in this instance probably made some 

 mistake. The paragraphs in which the statement appears 

 were written l)y him in 1853 for Hewitson's use. The 

 statement is repeated — again without any indication of its 

 origin — in the first volume of the 4th edition of 'Yarrell,' 

 and of course it has since found its way into other j)ubli- 

 cations. The idea of a pair of Sea-Eagles having their evrie 

 on the Bass makes a strong appeal to the imagination, and 

 naturally writers of articles on the bird-life of the famous 

 Kock like to introduce it. Its re-statement quite recently 

 in two articles in the daily press has revived my interest in 

 the matter, and prompted me to send you this letter in case 

 some member of the B,0,U, can solve my difficulty. Person- 

 ally, the middle of a great Gannet colony does not appear to 

 me to he a nesting-site quite suited to the tastes of the 

 White-tailed Eagle, If Wolley had said St. Ahb's Head, 

 there would at least have been the '' Earnsheugh,^' a elill' to 

 the west of that point, to give colour to the assertion.

A Correction, 



Sir, — I wish to make the following correction to my 

 paper, "The Birds of Tasso and adjoining Islands of the 

 Rokelle River, Sierra Leone," in 'The Ibis' for April 1921, 

 page 271 : for Blue Flycatcher {Platijsteira cyanea) read 

 Blue Flycatcher {^Elininia lonyicuuda).
