804 AMERICAN GAME. 
ly made out as permanent varieties; and that the 
variations of color from dark, green and greenish 
brown, to bright yellow, silvery, and something nearly 
approaching to orange, are merely local, casual, and 
individual differences, and not general, permanent, 
specific distinctions. 
The following luminous description of this game and 
excellent fish is borrowed from Dr. Richardson’s Tawra- 
boreali-Americana, or natural history of the Northern 
Regions of America, including parts of the United 
States, and the British Provinces as far north as to the 
Arctic Ocean. The specimen from which it was com- 
piled was caught at Penetanguishine, on the great 
Georgian bay of Lake Huron, but will answer for fish of 
this genus taken in any part of America which they 
may chance to frequent; so small is their variation in 
any respect but that of*color, which appears to vary in 
obedience to no fixed law of locality or latitude, except 
that it appears to me that of the fishes taken in estuaries 
and at the mouths of tidal rivers, the color is deeper and 
the tints fade from cerulean black along the dorsal out- 
line to olive green on the flanks, with a silver belly; 
while in clear lakes.and fresh streams, they change from 
olive-green on the back to bright golden yellow on the. 
sides and belly.
