The study here reported has benefited from coUections made by 

 the Honolulu division of the U.S. Fish and Wildlife Service and 

 from the assistance given to the author by the Division of Marine 

 Invertebrates of the Smithsonian Institution, especiaUy by Drs. 

 Bo^^^an, Mannmg, and Cressey, whose assistance with the syn- 

 onymies is deeply appreciated. The author is also grateful to the 

 officers and crew of the U.S. Coast Guard vessel Buttonwood and to 

 Lester Zukeran and Samuel Kaolulo for the collection of both host 

 and copepod material. 



Methods.— The external surface, gill cavities, buccal cavity, and 

 nasal cavities of the teleost hosts were examined for parasitic copepods. 

 Copepods coUected were kiUed in either 95 percent ethyl alcohol or 

 10 percent formalin and later transferred to 95 percent ethyl alcohol. 

 Specunens to be dra^^^l or dissected were placed m 85 percent lactic 

 acid to clear and soften them, stamed with Chlorazol Black E dis- 

 solved m 85 percent lactic acid, and then placed in benzyl alcohol tor 

 final clearing and for dissection and drawing. 



Drawmo-s of the enthe anhnal were made from specnnens placed 

 in benzyl ''alcohol and covered with a cover shp, supported so that 

 the shape of the organism was not distorted. Both a camera lucida 

 and a Bausch and Lomb Tri-Smiplex Micro-Projector were used m 

 makmg the drawings. The appendages and processes were drawn_ m 

 situ or were removed and mounted m either Hoyer's mountmg 

 medium or a 1:1 mixture of Turtox's CMC-10 and CMC-S. Meas- 

 urements were made with an ocular micrometer on specunens softened 

 m lactic acid and held loosely in place by a cover shp supported 



by spacers. , i + i„ 



In the following figures the 9 and c^ signs are used separately 

 under each drawing to mdicate a difference between the appendage 

 or body part of the female and that of the male. The symbols are 

 used together (9 cT) to mdicate the shnilarity of the appendage or 

 body part in both sexes. In the latter case the sex of the specimen 

 from which the drawing is made is indicated by a fine under the 

 appropriate symbol. If only one sex is represented in the coUection, 

 the symbols are not used. ■ j- 4. 



Terminology.— The term "cephalothorax" is used to mdicate a 

 condition m which one or more of the thoracic segments are fused with 

 the cephalon. The maxfiliped-bearmg segment is considered as the 

 first thoracic segment. The term "pedigerous segment" is used to 

 indicate a leg-bearing thoracic segment, while the terms "free thoracic
