IT is matter of ud little surprise thai we have not yet discovered Fork- 

 tailed Petrels among the local breeding birtls of the Olympiades. ^Ir. Finley 

 assures me that they abound upon the Three Arch Rocks of Oregon and their 

 breeding range extends north to the Arctic Circle. Mr. A. W. Anthony has 

 seen them in winter off our coast, and there is every reason to suppose that 

 local breeding grounds will yet come to light. 



In lial)its these Petrels do nut dilYer materially from the well-known 

 Kaedings. Indeed. ■\Iailiiard found these two species nesting side by side on 

 St. Lizaria, near Sitka, and the only difference discovered was that the eggs of 

 fiiirata were a trifle larger and much more ailvanced in incubation.
