Distribution 



P. mcmi was found primarily at Indian 

 and Pacific Ocean localities distributed in a 

 zonal band lying roughly between lat. 20 °N 

 and 20° S (Figure 12). Occurrences at higher 

 latitudes are few and mostly in the vicinity of 

 western boundary currents; e.g., in the Kuroshio 

 Current region just east of Japan and east of 

 southern Africa in the region of the Mozam- 

 bique and Agulhas Currents. In the eastern
