Is a very valuable river-fish; the characters of which are these. It has a long body; its head is short and round, its nose blunt at the end: its tail is very broad; its mouth large, and each jaw furnished with one row of sharp teeth. In its palate there are three parcels of teeth, each of an oblong figure, in the congeries, and all meeting in an angle near the end of the nose; the tongue has also six, eight, or ten teeth on it. It is very beautifully variegated on the sides with red spots. The colour of the Trout, and of its spots, varies greatly in different waters and different seasons; yet you may reduce each to one species.

In Llyndivi (a lake in South Wales), there are Trouts called Coch y Dail, marked with red and black spots about the size of a sixpence; others, not spotted, and of a reddish hue, which sometimes weigh from eight to ten pounds: they are very ill tasted. In Lough Neagh, in Ireland, there are Trouts called Buddagh, many of which weigh thirty pounds; others are taken of a much superior size, in Hulse Water (a lake in Cumberland), the same as those Trouts in the lakes of Geneva.

The stomachs of the common Trouts are very thick and muscular, as they feed on the shell fish of lakes and rivers as well as the small fish; and take gravel or stones into their stomachs to assist in comminuting the testaceous parts of their food. The Trouts of certain lakes in Ireland are remarkable for the great thickness of their stomachs, which, from some resemblance to the digesting organs in birds, are called Gizzards; and the species which have them, are called Gizzard Trouts. These stomachs are frequently served up to the table in Ireland, under the nomination of Gizzards.

Trouts are a very voracious fish, affording the angler great amusement. The under jaw of the Trout is subject to the same curvature as that of the Salmon. There is likewise a species of Trout, which migrates out of the sea into the river Esk in Cumberland, from July to September, and called, from its colour, the Whiting. Its taste is delicious. When they first make their appearance from the salt water, they have a Salmon Louse adhering to them. They have milt and spawn; but no fry has been yet observed. It goes under the appellation of Phinocs, among the Scotch. They are never more than a foot in length; the upper jaw is somewhat longer than the lower; the upper contains two rows of teeth, and the lower one: on the tongue there are six teeth. Its form is truly elegant; the colour dusky, mingled with silver. First dorsal fin spotted with black; the tail quite black, and forked; the first dorsal fin has eleven rays; the pectoral thirteen; the ventral nine; the anal nine.
