FORK-TAILED PETREL. 



leach's petrel, fork-tailed storm petrel, 

 plate ccxxxii. fig. iii. 



Procellaria Leachii, . . . Bewick. Jenyns. 



Pi'oceUaria Biillockii, . . . Fleming. 

 Thalassidroma BiiUochii, . . Eytojj. 



Thalassidroma Leachii, . . . Gould. Temminck. 



This Petrel burrows in the sand, or adopts a hole 

 or hollow in a rock for its nest. 



The e^^ 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.
