So far as we are aware, the Black-and- White Stormy Petrel is only known to 

 have been taken in a single instance within onr waters, and its claim to a place 

 in the fauna of North America rests entirely on the capture of these sjjecimens 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 Avas secured by Mr. John Hooper, of Brook- 

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

 met with. In regard to their distribution in other parts of the Avorld, and habits 

 generally, I have no information.
