Thirteen species are known, chiefly distributed in the 

 warmer parts of the temperate zones, and more scantily repre- 

 sented between the tropics. Several species (P. vulgaris, 

 P. avriga, P. hocagii) occur in the Mediterranean and the 

 neighbouring parts of the Atlantic ; one (P. argyrops) is well
