PELATES Cuvier & Valenciennes. 



Pdates Cuvier & Valenciennes, Hist. Nat. Poiss., iii, 1829, p. l-io {quadrilineatus). 



This genus is well differentiated from Thercvpon by having the gill-membranes 

 imited to the isthmus. The teeth are flattened, and arranged in three rows on the 

 upper jaw and in t^o on the loM'er.

P. sexlineatus is very similar to P. quadrilineatus Bloch in all structural details, 

 but appears to differ constantly in lacking the dark shoulder-mark and the black 

 blotch on the dorsal fin which is characteristic of that species. It is so far known only 

 from Eastern Australia. Specimens are in the Australian Museum from near Sydney, 

 and Queensland.
