_The Perch._—With two members of this family alone are we personally acquainted, viz. the yellow perch and the white perch. The first is a beautiful fish, and found in nearly all the waters of the Northern and Middle States, and probably as well known throughout the world as any of the finny tribes. Its predominating color is yellow; it has an elegant form, is a bold biter, varies in weight from four ounces to a pound (although occasionally found in New England weighing two pounds); has a dry and sweet flesh, but ill adapted to satisfy the cravings of a hungry man on account of its bones, which are particularly numerous, hard, and pointed. They generally swim about in _schools_, and yet at the same time are not at all distinguished for their intelligence, being invariably allured to destruction by the most bungling anglers, and the more common kinds of bait. They spawn in the autumn, and recover, so as to be in fine condition, early in the spring. They delight in clear rivers or lakes, with pebbly bottoms, though sometimes found on sandy or clayey soils. They love a moderately deep water, and frequent holes at the mouth of small streams or the hollows under the banks. With regard to the white perch we have only to say that it is well described by its name, is a migratory fish, found in nearly all the rivers of the Atlantic coast, from Boston to Norfolk; and they weigh from six ounces to one pound, are in season during the spring and summer, are capital as an article of food, and afford the entire brotherhood of anglers an abundance of sport. As touching the name of the fish now before us, we desire to chronicle our opinion respecting an important instance in which it has been misapplied. Many years ago, while reading the remarkable and intensely interesting work of Audubon on the birds of America, we chanced upon the description of a fish, found in the Ohio, to which he gave the name of white perch. Subsequently to that period, while sojourning in the city of Cincinnati, we happened to remember Mr. Audubon’s description, and one morning visited the market for the purpose of examining the fish. We found them very abundant, and were informed that they commanded a high price. On examining the fish, however, in view of certain doubts that we had previously entertained (for we knew that the white perch of the book was a native of salt water), we found it to be not a legitimate white perch, but simply the fish known on Lake Erie as the fresh water sheepshead. But this misapplication of the term perch is not peculiar to the residents on the Ohio, for we know that, throughout the Southern States where the black basse is found, it is universally called the black perch; and that in the vicinity of Boston and Nahant the miserable little fish called the conner is there designated as a black perch. That there are several varieties of the real perch besides those which we have mentioned we do
