The single known example of this species was procured in April, 1880, at Mount 

 Morris, Livingston Co., New York, and is now in the collection of Mr. William Brewster, 

 who first identified it as (E. gularis (Peale), but in 1886 came to the conclusion that it 

 was a distinct species, and named it (Estrelata scalaris. 



" This Petrel," writes Mr. Brewster, " differs from CE. fisheri in having a stouter, more 

 strongly-hooked bill, much shorter nasal tubes, less white on the forehead, crown, 

 and wings, the inner two pairs of tail-feathers perfectly plain on both webs, and the 

 outer three pairs with faint sparse mottling on the inner webs only. From both 

 CE. fisheri and CE. gularis it differs in having the feathers of the back, as well as the 

 greater and middle wing-coverts, tipped and edged with white, giving the back a 

 scaled appearance, and on the wings forming distinct bands. Neither CE. fisheri nor 

 CE. gularis shows any trace of white on the back, and neither has anything approaching 

 well-defined wing-bands. The nostril-tubes in CE. scalaris are apparently shorter and 

 more prominent than in CE. gularis, their superior outline straighter, the ends more 

 squarely cut off, and less deeply incised. . . 



" Despite the wide dissimilarity in colouring, the bird under consideration is clearly 

 more closely related to CE. gularis than to any other known species. They may prove 

 to be merely the dark and fight extremes of a species subject to dichromatism." 



The following description of the original specimen was published by Mr. Ridgway 

 in his " Manual," and copied by Salvin in the " Catalogue of Birds " (p. 416). 



" Inner webs of primaries abruptly white for at least the inner half. Wing more 

 than 9 inches. Above, including the whole top of the head, dark bluish-grey, the
