NO. 3570 PANDARIDAE — CRESSET 9 



single plumose seta and stout spine borne on genital segment near 

 origin of abdomen (see also fig. 16). 



Color in life whitish yellow and generally devoid of darker pigment. 



Discussion. ^ — Pandarus satyrus is a widely distributed copepod 

 nearly always found associated with Prionace glauca. Reports in 

 the literature of this copepod from other hosts are probably the result 

 of misidentification of the copepod or even of the host shark. It is 

 closely related to Pandarus cranchii Leach and was placed in synonymy 

 with it by Shiino (1954) . I have examined a gi-eat number of specimens 

 of both of these species and conclude that both are valid species. The 

 principal differences between them are discussed imder the description 

 of Pandarus cranchii. 



This copepod is parastic on the body surface of the host and is often 

 found in large clusters near the posterior edge of the fins. Generally 

 the number of females far exceeds the number of males.
