Volume 121 19(37 Number 3574 COPEPOD CRUSTACEANS PARASITIC ON TELEOST FISHES OF THE HAWAIIAN ISLANDS ' By Alan G. Lewis ^ Introduction This is the third and last of a series of papers covering the copepod parasites of Hawaiian fishes. The first (Lewis, 1964a) deals vnth the caligoid copepod parasites of Hawaiian acanthurid fishes, the second (Lewis, 1966) covers the copepod crustaceans parasitic on elasmo-branch fishes, and the present paper deals with copepod crustaceans parasitic on teleost fishes. An additional paper (Lewis, 1964b), deal-ing vnth the caligoid genus Dentigryps, includes descriptions of two spe-cies found on Hawaiian fishes. Other than the papers mentioned above, the references to copepods taken from Hawaiian teleosts are those of Nordmann (1864), de-scribmg Norion expansus and Peniculus calamus from unknown hosts, and Edmondson (1946), who figures a species of Lernaeenicus from dolphins. Bonnet (1948) lists some Hawaiian copepods taken primarily from pelagic fishes, and Shimo (1963) describes Midias lobodes, Caligus coryphaenae, and BracUella thynni from fishes ex-ammed in t he Honolulu Fish Market.
