NOTES ON THE GORDON COLLECTION OF ECCS OF 

 THE ACCIPITRES; 



By H. KiRKE SWANN. 



The very interesting account of his collection given by Mr. 

 Gordon in the March number of " The Oologists' Record " tempts me 

 to add some supplementary remarks, principally on rare eggs in my 

 own collection and eggs which Mr. Gordon does not possess. Mr. 

 Gordon's and my own are the only two important collections of 

 eggs of the Accipitres outside the Museums, and I believe I am the 

 only collector confining himself entirely to the Accipitres. 



Mr. Gordon states he has 172 forms all told, plus two additional 

 mentioned by the Editor, and minus one inserted in error. I have 

 at present 170 forms, but, although I possess a great many more 

 eggs than Mr. Gordon, I have only 36 forms he has not got, while I 

 lack 38 of those he possesses. 



Our united collections, therefore, contain the eggs of 208 forms 

 of Accipitres. The British Museum collection contains the eggs of 

 at least 45 forms not represented in either of our collections. Tring 

 Musevmi, out of a total of about 150 forms, has about 40 I do not 

 possess, but a number of these are included in the British Museum 

 figure. I have over 50 forms myself not represented at Tring. 



There are also a few additional known eggs in the Norris and 

 other collections, as well as in the American and other foreign 

 museums. Therefore we may conclude that the eggs of not more 

 than 300 forms are known out of the total of 682 I enumerate. I 

 will now proceed with a few remarks on the eggs in my own 

 collection that are especially worthy of note. Those marked with 

 an asterisk (*) are not represented in the Gordon collection. 



*Gymnogyps caUfornianus. Calif ornian Condor, c/1. From the 

 Mexican border. The known eggs are very few in number. 



.Egypiiis monachtts. Cinereous Vulture. 6/1. The largest and most 

 handsome of my eggs are from Semiretschje-gebiet, Kuldscha, 

 Asia, but I have a smaller egg, taken by Howard Saunders at
