From Mr. Gifford’s notes it appears that Dark-rumped 
Petrels were first met with by the Expedition on July 31, 1905, 
in latitude 14° N., longitude 110° W. Early in the morning 
the vessel sailed by a large flock of birds, composed chiefly of 
these petrels, Wedge-tailed Shearwaters, and Noddies. At 
midday a similar flock was encountered. On August 1, lati- 
tude 13° 28’ N., longitude 108° 52’ W., three males and three 
females were taken. During the cruise south of latitude 14° 
N. Dark-rumped Petrels were prominent in the bird life of the 
sea, occurring from the vicinity of Clipperton Island, east- 
ward to within a few miles of the Ecuador coast, and south- 
ward to latitude 4° 25’ S., longitude 93° 30’ W., the most 
southerly position attained by the Expedition. On the voyage 
north the last Dark-rumped Petrel was seen September 29, 
1906, in latitude 9° 22’ N., longitude 98° 25’ W. 
Whether the great stretch of ocean between Clipperton 
Island and the Hawaiian Archipelago is frequented by these 
petrels is not definitely known. It may be that the Hawaiian 
birds are isolated at all seasons from the birds occurring off the 
American coast. 
Mr. Gifford’s Galapagos notes are condensed in the follow- 
ing paragraphs: 
Dark-rumped Petrels were present during the entire year in 
the archipelago. They were inclined to shun the quiet bays 
and coves and frequent the open sea. At times they were very 
common. The largest gatherings were seen off Iguana Cove, 
Albemarle Island, in April and off Indefatigable Island in July. 
They breed on Indefatigable Island in the humid uplands—a 
foggy zone of forests and dense undergrowth. Similar situa- 
tions on James and Albemarle islands are probably inhabited 
by breeding colonies. Protracted rainy weather, dense vegeta- 
tion requiring the constant use of the machete, and lack of 
time prevented a thorough exploration of their breeding haunts. 
Nevertheless, Mr. Beck succeeded in securing a male and a 
fresh egg on July 22, 1906, from a burrow in the forest on the 
northwestern side of Indefatigable Island at an elevation of
