416 ORNITHOLOGY. 



Not entirely satisfied that this is the species meant by Gmelin and 

 Latham, we give it provisionally only as Procellaria nivea, but should 

 another white species, with the shafts of any of its feathers black, as 

 described by those distinguished authors, become known, this name 

 must give place to that of Mr. Peale, above cited. 



Our plate represents this bird rather smaller than the size of life.

Of this well-known bird we find numerous specimens in the collec- 

 tion of the Expedition, and it is frequently mentioned in the Journal 

 of Dr. Pickering. These specimens present no characters other than 

 have long been known to naturalists. 



The first notice of this species, by Dr. Pickering, is on the 19th day 

 of January, 1839, in latitude 39° S., in the Atlantic Ocean. Subse- 

 quently, it is mentioned by him at various points, and, for the last 

 time, on the 14th day of July, in the same year, on the western coast 

 of South America, the day after sailing from the harbor of Callao, in 

 about 12° S. latitude.
