" Irides brown ; bill black ; feet pale flesh-color ; the toes black at 

 their ends. Extent of wings twenty-four and one-fourth inches." 

 (Peale.) 



The specimens of this bird, in the collection of the Expedition, are 

 from a much more eastern locality than heretofore noticed, as will 

 appear from the following note by Mr. Peale : 



" Two specimens were shot on the 21st of March, in latitude 68° S., 

 longitude 95° W. Their flight was very swift, wild, and irregular, 

 and they evinced no partiality for the vicinity of the ship, although 

 she was lying-to in a dense fog, a time when Petrels generally collected 

 around us to glean the offal thrown overboard." 



The locality here given is much nearer the continent of America 

 than this bird has ever before been noticed by voyagers. We find the 

 two specimens, above alluded to, in the collection of the Expedition, 

 and, on comparison with others from Mr. Gould's collection, now in 

 the Museum of the Philadelphia Academy, can distinguish them by 

 no character whatever. 



* " Head and wings sooty-black ; back and tail gray; throat, breast, and belly, white, 

 tinged with salmon-color when living, but changing to white after death ; an interrupted 

 plumbeous band crosses the breast ; two outer tail-feathers light gray, white beneath, 

 shafts white; all the others brown ; under wing-coverts white; the lesser ones nearly 

 black ; bill black ; feet pale flesh-color ; the toes black at their ends ; irides brown. 



" Total length ten and seven-tenths inches ; extent of wings twenty-four and one- 

 fourth inches ; bill, to the angle of the mouth, one and four-tenths inches ; over the 

 culmen nineteen-twentieths of au inch ; middle toe, including the nail, one and three- 

 tenths inches."
