differ also in the presence of two marginal, hairlike setules on the 

 protopodite of the fourth thoracic leg of C. kalumai, which are absent 

 on C. punctatus. In addition, the second segment of the exopodite 

 of C. punctatus, as shown by Shiino (1955), appears much longer 

 than the first segment while it is only sUghtly longer than the first 

 segment in C. kalumai. Other characteristics serve to differentiate 

 these two species, but it appears that these two, in addition to C. 

 oviceps, are morphologically similar. 



The name "kalumai" is derived from two Hawaiian words. The 

 first word, "kalmnu," means "to swell." The second, "ma'i," is the 

 term for genitals. The combination of the two terms is used to in- 

 dicate the condition of the genital segment in the holotype female 

 specimen. 



Genus Lepeophtheirus Nordmann, 1832 



Diagnosis. — Abdomen of one or two segments, usually distinct from 

 genital segment. Lunules absent. Postoral process simple or 

 bifurcate; sternal furca present. First three thoracic legs biramous 

 though endopodite of first rudimentary; fourth leg uniramous, 

 typically with four segments. 



Remarks. — Nordmann does not give a synopsis of the characters 

 of the genus in his 1832 publication. The characteristics given 

 above were taken primarily from Wilson (1932) and were modified 

 from descriptions of members of the genus Lepeophtheirus given by 

 other authors and from the personal experience of the present author.
