Leach's Fork-tailed Petrel breeds in the Kurile Islands (Blakiston 

 and Pryer, Ibis, 1878, p. 218). There is an example in the Pryer 

 collection obtained by Mr. Snow in this locality, and Captain 

 Blakiston has sent me others (Seebohm, Ibis, 1884, p. 33). 



Leach's Fork-tailed Petrel breeds on some of the western islands 

 of Scotland and Ireland, as well as in the Bay of Fundy on the 

 American coast. These colonies appear to be completely isolated 

 from the colony in the North Pacific, which extends to the Com- 

 mander Islands and the Aleutian Islands. 



266. PROCELLARIA MELANIA. 

 (BLACK PETREL.) 

 Procellaria melania, Bonapaite, Compt. Bend, xxviii. p. 662 (1854). 



The Black Petrel is slightly larger than Leach's Petrel (wing from 

 carpal joint 6;^ inches), the fork of its tail is somewhat deeper (I^ 

 inches), and the rump and upper tail- coverts are sooty brown like 

 the rest of the plumage ; but in both species the margins of the 

 tertials and scapulars are paler.
