MEASUREMENTS.—Males, 21-43 mm.; females, 20-121 mm.; juvs., 
9-20 mm. 
Remarks.—In many specimens the red marks on the carapace are 
indistinct or unrecognizable because they have faded after prolonged 
preservation. In such cases the species can be recognized by frontal 
teeth (figs. 12a, b) that are more equal in size and more evenly spaced 
than in P. pelagicus and by the merus of the third maxilliped, which 
is hairy as opposed to the smoothness in P. pelagicus. 
Possibly P. madagascariensis (Hoffmann) is a synonym and based 
upon a faded specimen (see Crosnier, 1962, p. 47).? 
DistriputTion.—Kast Africa to Hawaii, including Japan and 
Australia and also from the Adriatic.
