Wilson's Storm-Petrel is one of the most widely distributed of the whole Order 

 Tubinares, having been found everywhere except in the North Pacific Ocean. It has 

 been suggested that two forms of the species exist, viz., a northern and a southern one, 

 the former having been separated by Bonaparte as larger, and having a more slender 

 bill and longer tarsi, while, at the same time, there was less white on the wing, and 

 the tail was emarginate. 



Professor Giglioli was inclined at one time to agree with Bonaparte, and believed 

 that the larger form, O. oceanicus, was confined to the South Atlantic Ocean, the 

 Indian Ocean, and the Australian seas. 0. wilsoni, on the other hand, was considered 

 to inhabit the North Atlantic islands, the coasts of the United States, and the Pacific
