76 EGGS OF BRITISH BIRDS. 



THE CANAEIAN FORK-TAILED PETEEL. 

 (Oceanodroma cryptoleucura.) 



This species was originally described from the Sandwich 

 Islands, but it has recently been discovered in the Salvage 

 Islands, the Canaries, and on St. Helena in the Atlantic. A 

 specimen, now in the collection of Mr. Boyd Alexander, was 

 picked up dead on the beach at Littlestone in Kent, on the 

 5th of December, 1895. 



Mr. Ogilvie-Grant describes the egg as exactly like that of 

 Leach's Petrel, and measuring 13 by 096 inch. It has, there- 

 fore, not been thought necessary to figure it. 



WILSON'S PETEEL. 

 (Oceanites oceanica.) 



This is a southern species, which breeds on Kerguelen Island, 

 and probably on other islands of the South Atlantic Ocean. It 

 wanders north, and has many times been obtained off the shores 

 of Great Britain. 



The Rev. A. E. Eaton says that in Kerguelen Island these 

 Petrels love to make their colonies on the slopes of shattered 

 rocks, wherever there are suitable chinks and crevices, or dry 

 places under stones and large boulders, either close to the sea, 

 just above high-tide mark, or on the sides and summits of high 

 hills. He obtained eggs in January and February. They are 

 white, with a more or less obscure zone of minute reddish-brown 

 spots, generally round the larger end. They are of about the 

 same size as those of the Fork-tailed Petrel, and consequently 

 cannot be distinguished from them, averaging about 13 inch 

 in length, and 09 inch in breadth.
