HAWAIIAN ACANTHURID CALIGOIDS — LEWIS 195 



Because of the variety of characteristics that are exhibited by members 

 of this genus, Shiino (1954) has aptly termed it a "waste-basket for 

 such species that can not be located in Lepeophtheirus." With the 

 description of more species in the genus, a series of characteristics may 

 be worked out to delimit the genus more distinctly, or else the charac- 

 teristics of related genera may be expanded to include the species now 

 placed in the genus.

Material. — Ovigerous female (holotype, USNM 105098) collected 

 by author from dorsal fin of specimen of Naso hexacanthus (Bleeker) 

 taken in fish trap between Diamond Head and Koko Head, Oahu, 

 Hawaii, by Samuel Kaolulo. Adult male (allotype, USNM 105099) col- 

 lected by author from dorsal fin of specimen of Naso hexacanthus (Blee- 

 ker) taken in fish trap between Diamond Head and Koko Head, Oahu, 

 Hawaii, by Samuel Kaolulo. Three adult females and three adult 

 males (paratypes, USNM 105101) taken by author from dorsal fin 

 of single specimen of Naso hexacanthus (Bleeker) collected in fish trap 

 between Diamond Head and Koko Head, Oahu, Hawaii, by Samuel 

 Kaolulo. Adult ovigerous female (paratype, USNM 105100) taken 

 by author from side of specimen of Naso unicornis (Forskal) speared 

 by author at Bird Island, Oahu, Hawaii. 



These specimens were taken from a collection of over 100 specimens 

 and represent the Hawaiian population of the copepod.
