Pterodroma externa 
One bird of this species was seen on the 19^* It was not 
assigned to race* 
Pterodroma sp. 
Three birds were identified only to this genus. One bird seen 
on the 26^ was a small P. hypoleuca- sized bird. The underwings were 
white with little or no black boarders. Thebreast and belly were white. 
It appeared uniformly gray on the top of the head, back, and tail. The 
only bird I am familiar with these markings is the Black-winged Petrel, 
but it has the dark bordering the white on the underwings* 
Storm Petrel (White-rumped) 
Thirty-three storm petrels were recorded. Since no collecting was 
specific identification is not definite. Most birds appeared to be 
Leaches Storm ^etrels. One bird seen on 22 ^pril had a brilliant white 
rump patch. This bird could have been a Harcourt*s Storm Petrel.
