THIS Petrel breeds in burrows in the sand, among 

 stones, or adopts a hole or hollow in the cleft of 

 a huge wave-worn rock for its nest. 



The egg is white only one is laid. It is of 

 large proportionate size. 



I have to thank the Rev. H. B. Tristram for the 

 loan of the egg from which the plate is taken. It 

 was had by him from St. Kilda.
