Mr. H. KiRKE SwANN exhibited the following raptorial 



eggs 



Falco peregrinus anatum. Set of four eggs from 

 California, May 6th, 1914. 



Falco peregrinus pealei. Set of four eggs from For- 

 rester Island, Alaska, May 3rd, 1920. Very dark 

 eggs. 



Falco peregrinus peregrinus. Set of three British eggs 

 for comparison. Also one white egg taken in the 

 Orkneys in 1868 by Dunn and stated to be a 

 Goshawk's, but evidently a white Peregrine Falcon's. 

 This eeg had been through the collection of Colonel 

 Hanbury Barclay and other collections. 



Polyhorus lutosus. An egg, probably the only one 

 known, of this Carrion-Hawk, now extinct. It was 

 taken on Guadeloupe Island, W. Mexico, April 17th, 

 1897. 



JButeola hracliyurus. Set of two eggs taken in Dade Co., 

 Florida, March 27th, 1910. The nest was in a large 

 cypress in 7 feet of swamp water, and the eggs 

 were taken for three years in succession, when the 

 tree was blown down in a storm and the birds left. 

 This S. American species is very rare in Florida, 

 and not many eggs exist in collections. 



Buteo solitarius. Set of two eggs from the Hawaiian 

 Islands, taken February 11th, 1921. 



Dr. Ernst Hartert exhibited, on behalf of Lord Roth- 

 schild, who, to his regret, was unable to be present, the 

 following eggs, and made remarks upon them : — 



Rhamphocorys clot-bey, Algerian Sahara. These rare 

 eggs, evidently not represented in any other British 

 collection, were collected in 1913 and 1914. The 

 clutches varied from one (rare) to four, and once 

 one of five was taken. 



Ammomanes deserti algeriensis, Algerian Sahara.
