COPEPODS GATHERED BY THE UNITED STATES 
FISHERIES STEAMER “ALBATROSS” FROM 1887 
TO 1909, CHIEFLY IN THE PACIFIC OCEAN 
By Cartes Brancnw WILSON 
INTRODUCTION 
The United States Fisheries steamer Albatross made her first voy- 
age in 1883. The vessel was designed chiefly for the investigation of 
fisheries and fishing grounds, and in connection with this work it did 
a great deal of dredging and tow-netting. Thus large collections 
of the oceanic fauna and flora were gradually accumulated, some of 
which were submitted to various specialists for identification and 
report, while others were stored for future study. The latter was 
the fate of the copepods, which remained unidentified except for the 
few Atlantic species that were studied by Richard Rathbun, who gave 
special attention to their colors when alive. These Atlantic forms, 
together with Rathbun’s valuable notes upon them, were incorporated 
in the present author’s report upon the copepods of the Woods Hole 
region, published in 1932 as Bulletin 158 of the United States National 
Museum. 
The present paper contains the remainder of the copepods which 
were gathered chiefly during the following voyages of the A/batross: 
(1) A voyage around South America and up the eastern Pacific, 
1887 to 1888; (2) voyages across the tropical Pacific to Japan and 
Kamchatka, 1899 to 1901; (8) a cruise among the Hawaiian Islands 
in 1902; (4) collecting from California southward in the eastern 
Pacific in 1904; (5) investigations in connection with the Alaskan 
salmon fisheries in 1908 and again in 1905; (6) a voyage through 
the northwestern Pacific in 1906; and (7) a 3-year cruise among the 
Philippine Islands, 1907 to 1910, which yielded the greatest number 
of specimens. 
No effort was made to deal with the copepods during these two 
decades, and by 1911 the numbers had reached formidable proportions. 
Most of those taken in the first six of the above voyages and a very 
few from the seventh were then sent to Dr. Georg Ossian Sars in 
Norway for identification and report. He isolated and labeled about 
two-fifths of the collection, listed the stations at which the species
