tinged with green and the belly pure white. In the yellow water 
of the reed-beds the back and sides are much darker, sometimes 
almost black. A few silvery scales are always present on the 
back and some adult males have the fins reddish, and dull red 
specks scattered on the dorsal surface.

There are great differences in appearance, proportions and 
lepidosis between young and adults of this species, the chief 
being that the young are more slender, more silvery, have very 
much larger dorsal and caudal fins and eyes, and more imperfectly 
developed scales. In specimens between 56 and 66 mm. long we 
can detect no scales at all, while in those from 91 to 95 long they 
are much smaller in proportion than in the adult and are devoid 
of circular striae. 
In specimens up to 123 mm. long the caudal fin occupies 
about 1 of the total length, while in the adult it occupies only 
from :to.1. In specimens up to 93 mm. long the dorsal fin is 
considerably deeper than the body; in one 123 mm. long it 
is almost as deep, but in the adult it is distinctly less deep. The
