Copepod Crustaceans Parasitic 
on Fishes of Eniwetok Atoll ’ 
By Alan G. Lewis ? 
Copepod parasites of fishes of Eniwetok Atoll, one of the Marshall 
Islands, have not been previously studied. The only reference dealing 
with parasitic copepods from this general region of the Pacific is that 
of Heegaard (1943) concerning some caligids from the Gilbert Islands. 
Both Heegaard (1940, 1962) and Kabata (1964, et al.), however, 
have described copepods from fishes from the neighboring Australian 
region, some of which are also found on fishes from Eniwetok Atoll, 
and Hewitt (1963, et al.) and Thomson (1889) have described copepods 
from fishes of New Zealand. These studies, as well as those of Lewis 
(1964a, et al.) concerning copepods from Hawaiian fishes, cover most 
of the named species although some of them have previously been 
described from other areas, primarily the western Pacific and the 
Indian Ocean. 
The study herein reported is based on two collections made by the 
author during the summers of 1959 and 1961. He is indebted to the 
U.S. Atomic Energy Commission for the use of the facilities at the 
Eniwetok Marine Biological Laboratory. He is also grateful for the
