to be thrown over to them. They had probably learned to expect 

 food from ships by being near the whaling vessels while they were 

 " cutting in " or " trying out " a whale, at which time large quanti- 

 ties of fat and refuse are thrown over the side. Hab., Bering Sea, 

 Arctic Ocean north to Point Barrow. 



91. Puffinus creatopus. Pink-footed Shearwater. 



A great flight of Pink-footed Shearwaters was observed May 

 26th about fifteen miles off Cape Flattery. They were passing to 

 the north in a continuous stream. I watched from the deck of our 

 vessel for over an hour, during which time many hundreds passed, 

 frequently flying quite near us. Their large size, white breasts and 

 wheeling flight were unmistakable. Our vessel interrupted their 

 line of flight, but they simply divided, part of the stream going by 

 on one side, and part on the other. Never for a moment did they 

 stop the steady flow to the north. The Pink-footed Shearwaters 

 were not met with again during our entire trip. Hab., Eastern 

 Pacific Ocean, Cape Flattery to Chili. 



95. Puffinus griseus. Dark-bodied Shearwater. 



A few Dark-bodied Shearwaters were observed May 26th off 

 Cape Flattery. They were flying north in company with the Puf- 

 finus creatopus. Dark-bodied Shearwaters were again observed 

 June 22d in longitude 164° 55' W., latitude 52° 9' N., about sixty 

 miles south of the Aleutian Islands. At this point we encountered 

 and for several hours sailed parallel to a great flight of these birds. 

 During this time thousands of individuals passed us in Bteady flight, 

 all going to the westward. 



Oceanodroma (?). Petrels. 



Concerning Petrels I have the following entry in my note book : 

 June 16th, longitude 159° 58' W„ latitude 51° 56' N. For the 

 past two or three nights there has been a number of small bat-like 

 birds flying about our vessel keeping up an almost constant sound 

 of low musical notes. The sailors call them " Mother Carey's 

 Chickens." I was not able to secure a specimen for identification. 

 They may have been 0. furcata. 



Birds well answering the description of 0. furcata were observed 

 May 28th. They were flying about in the wake of our vessel, 

 skimming gracefully over the waves and occasionally dashing 

 through the spray as if they enjoyed the rough sea.
