are similar to those of P. sedentaria but have well-developed antennae II 

 (although much smaller than antennae I) and a much shorter anterior 

 distal tooth on the 5th segment of pereopods V; the 6th segment of pere- 

 opods V is also relatively shorter than in P. sedentaria or P. atlantica, 

 in which it projects beyond the anterior margin of the 5th segment by 

 more than 1/3 its length. 



Distribution: Atlantic Ocean, particularly its eastern part; western 

 part of the Mediterranean Sea, Indian Ocean, western and southern parts 

 of the Pacific Ocean. In temperate and high latitudes it does not cross 

 beyond the limits of the Subtropical Convergences.
