GAMMARIDEAN AMPHIPODA 89 



male gnathopod 2 of P. jerox has a long distally expanding hand 

 with transverse palm and quadrate palmar process. 



Pleonexes lessoniae Hurley (1954a) is undoubtedly in the correct 

 genus in view of its telson and pereopods but it differs from P. aptos 

 by the slender, almost simple gnathopod 1, with small transverse 

 palm and a greatly overlapped dactyl which is similar to those species 

 of Ampithoe such as A. lindbergi and A. humeralis. The palms of the 

 pereopods differ from those of P. aptos in their shape and spination. 

 The lower lip of P. lessoniae is quite different from those of the other 

 two pleonexids, the outer lobes being very broad distally, truncate, 

 and scarcely incised.
