REMARKS ON THE SPECIES OF THE PACIFIC

AND THE GALAPAGOS ISLANDS

MaTERIAL.—This part of the paper is based primarily upon 
the results of the Expedition of the California Academy of 
Sciences to the Galapagos Islands during 1905 and 1906 in 
the schooner Academy. The Expedition was planned and 
organized by myself in my official capacity as Director of the 
Museum of the California Academy of Sciences. Mr. Rollo 
Howard Beck was placed in command of the Expedition and 
its marked success was due chiefly to his sound judgment, 
strength of character, great physical endurance, and skill as a 
collector and preparator. In the preparation of the bird skins 
he was assisted by Mr. Edward Winslow Gifford and Mr. J. S. 
Hunter. Mr. Gifford kept the ornithological diary, and the 
portions relating to the albatrosses and petrels are incorporated 
in substance in the following pages. His observations were 
recorded with great attention to detail and add much to our 
knowledge. The Expedition sailed from San Francisco on 
June 28, 1905, and returned November 29, 1906. On the 
outward voyage stops were made at various islands along the 
west-coast of Lower California and at San Benedicto, Socorro, 
Clipperton, and Cocos islands. A year and a day were spent 
at the Galapagos Islands and in the immediate vicinity. No 
stops were made during the homeward voyage. Owing to 
calms and unfavorable winds, it consumed sixty-five days. 
The ornithologists availed themselves of every opportunity to 
collect albatrosses and petrels at sea. During calms Mr. Beck 
was continually out in a skiff, and secured numerous speci- 
mens that are rare in collections. 
The Galapagos Expedition material has been supplemented 
by specimens and notes taken by Mr. Beck off Point Pinos, 
California, at intervals between March 1, 1903, and July 13, 
1910, while employed as chief field assistant of the California 
Academy of Sciences.
