34 THE CYPRINODONTS. 
rently the description of L. cypris was drawn from small, and that of L. mento 
from larger individuals. Heckel says the belly of Z. 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 Z. cypris from Bagdad and the Jordan.
