rently the description of L. ci/pris was drawn from small, and that of L. nimto 

 from larger individuals. Heckel says the belly of L. mento is yellowish white, 

 the back brown ; the males are darker and have black fins with white dots ; 

 the females lighter with uniform white or yellowish white fins. Giinther 

 identifies the species L. ci/jyris from Bagdad and the Jordan.
