So far as we are aware, the Black-ami- White Stormy 1'etrel is only known to 

 have been taken in a single instance within our waters, and its claim to a phut' 

 in the fauna of North America rests entirely on the capture of these specimens on 

 -the Gulf coast of Florida. Seven examples of this bird are said to have been cap- 

 tured with a hook and line by the captain of a vessel while at anchor in the 

 harbor of St. Mark's, Fla. One of these was secured by Mr. John Hooper, of Brook- 

 lyn, N. Y. They were observed about the vessel two days; after which none were 

 met with. In regard to their distribution in other parts of the world, anil habits 

 generally, I have no information.
