MADEIRA STORM PETREL. 



Occanodroma eryptoleucura (RlDGWAY). 



* I A HIS near ally of the Fork- tailed Petrel was first described from the Hawaiian 

 _L Isles, but is now known to range from the Galapagos in the Pacific to 

 the Cape Verde Isles, St. Helena, Desertas, and Great Salvage Isles. It owes 

 its entrance into the British list to the occurrence of a single specimen obtained 

 at Littlestone, Kent, December 5th, 1895. Mr. Boyd Alexander and Mr. Ogilvie- 

 Grant have explored the Madeiran and Cape Verde haunts of this Petrel (see 

 "Ibis" 1896, pp. 53-54; it. cit. 1898, p. 98.) This Petrel burrows in the ground, 

 its nest-holes being more tortuous and deeper than those of the Frigate Petrel. 

 It lays a single white egg, " with an indistinct zone of light red, and faint 

 purplish underlying dots round the larger end." The bird closely resembles the 

 Fork-tailed Petrel, but has the tail nearly square, the outer feathers being only 

 slightly longer than the middle pair, the basal part of the outer feathers is 

 white, and the upper tail-coverts are white, tipped with black, instead of uniform 

 white (Ogilvie-Graut.)

THIS long-legged Petrel owes its trivial name to Alexander Wilson, by whom 

 it was erroneously identified with the Storm Petrel. It is a common 

 species on the American coasts, at least as far north as Labrador. Though rare
