This new species of Petrel was given me by Dr. C. H. Stilwell, 

 of Brooklyn, L. I., who obtained it in Florida during the winter of 

 last year. From him I received the following communication : 



" This bird was found floating, wounded, in the salt lagoon op- 

 posite Indian river inlet, on the eastern coast of Florida, two hun- 

 dred and forty miles south of St. John's river. No one of the set- 

 tlers could tell the name of it, and I suppose it is an uncommon 

 bird in that region, though 1 cannot say particularly, not being ac- 

 quainted there much." 



Birds of this genua are usually found in high latitudes, but from 

 the difficulty of obtaining them, as they are strictly sea-birds, it is 

 probable they are more frequent on our coast than is generally sup- 

 posed. At sea they are attracted around the stern of a vessel l>y 

 any small Boating substance, and at such times are often taken with 

 a line and fish-hook baited with fat. 



In lightness of form, great length of wing, and graduated tail, it 

 somewhat resembles the genus Puffiuus ; but the bill is so strongly 

 characteristic of the Fulmars, 1 have thought proper to class it 

 with them. 



NoTE. — This bird was noticed on the cover of Nos. 8 and !», 

 Vol. IV., of the Annals of the N'< w Vork Lyceum, under the spe- 

 cific name of Brevirostris ; but that name being pre-occupied by 

 mother species described in Lesson's Ornithology, the above one 

 is substituted.
