‘THE PERCH. 
Tux Yellow Perch ; Perca flavescens. . 
This fine fish, which belongs to the family Percoida, 
of the division Acanthopterygiz, or thorny-finned, is the 
common perch of the waters of the United States; 
ranging from the extreme east‘to the extreme west of 
the continent; from the streams and pools of Nova 
Scotia and New Brunswick, to the feeders of Lake Supe- 
rior and the northern tributaries of the Canadian lakes. 
To the northward, it is not found in the rivers flowing 
into the Arctic Ocean or Hudson’s Bay, and its southern 
limit is ill-defined, and can scarcely be ascertained, ex- 
cept by personal inspection; since the denizens of the 
southern waters have been disfigured by appellations, 
local, provincial, and most unscientifical, so barbarous 
as to defy the most intelligent inquirer. 
The title of the division Acanthopterygii, or thorny- 
Jinned, is founded on the principle that every genus and 
sub-genus thereof has one or more of the fins supported
