NO. 3653 COPEPODS—CRESSEY 3 
As in P. satyrus, this copepod has been redescribed recently (Cressey 
1967a), and no further description will be given here. 
Remarks.—The copepods of this species from the Atlantic were 
found in the mouth of the host. The single female representing the 
Indian Ocean collection from this host was on the body surface. 
Like P. satyrus, this copepod is a common parasite on the body sur- 
face of sharks, primarily carcharinids. Also, as in P. satyrus, those 
specimens from inside the buccal area of the host are not pigmented as 
heavily as individuals of the same species occurring on the body 
surface of other sharks.

America, R. V. Anton Bruun, Cruise 14, Stations 567, 568, 569, 
and 571. 
Remarks.—Pandarus katoi has been reported previously from the 
body surface of carcharinid sharks in the eastern Pacific (Cressey, 
1967a). The collections recorded above from J. oxyrinchus were 
removed from the mouths and gill arches of the hosts. The specimens 
in collections of this species from the body surface of other sharks 
are not pigmented as heavily as most other species of the genus 
Pandarus; nevertheless, the P. katoi from the mouths of makos are 
pigmented still less than those on the body surface of other sharks, 
consistant with the situation with P. satyrus and P. smithw reported 
above. The change in habitat for these three species is discussed at 
the end of this paper.

MarTErRIAL.—One collection off the west coast of South America, 
R.V. Anton Bruun, Cruise 14, Station 552 (1 9 specimen only). 
RemMArkKS.—The single specimen from the 32 sharks examined 
indicates a low incidence of this parasite. This copepod is more common 
on Prionace glauca and, since these two sharks often are found in the 
same waters, this may be a reflection of that association.
