THE TURBOT. The Turbot resembles a lozenge in general form. Its under jaw is more advanced than the upper one, and is furnished with many rows of small teeth. One side is marbled brown and yellow, and the other is white with brownish spots and points; the long rows of soft fins are yellow with brown spots. The true Turbot has always been the special delight of the epicure, and fabulous sums are said to have been paid at different times, in order to secure a fine specimen. THE FLOUNDERS AND PLAICE. The Flounders and Plaice inhabit the northern seas of Europe. They are also found along our coasts; the Flounders are fresh water Fishes of small size, abundant in the Thames and many other rivers; and they are desirable for food, although not so delicately flavored as the Turbot. The Common Plaice attains the length of ten or twelve inches. It is brown, spotted with red or orange. On the eye-side of the head are some bony tubercles, but the rest of the body is smooth. THE HALIBUT AND THE DAB. The Dab is distinguished from the other flat Fish by having very hard scales on its body, and the Halibut has the distinction of being the largest of this class of flat Fish. It is occasionally caught in the seas of Northern Europe and Greenland, measuring seven feet, and weighing from three to four hundred pounds. The body of the Halibut is more elongated than that of the Plaice or Flounder, and its jaws are armed with strong and pointed teeth. The natives of Greenland fish for the Halibut with an implement which they call gangnaed. It is composed of a hempen cord five or six hundred yards in length, to which are attached about thirty smaller cords, each furnished with a barbed hook at the end. The larger cord is attached to floating planks, which act as trimmers, indicating the place of this destructive contrivance. At the end of twenty-four hours these lines are drawn from the water, and it is not unusual to find five or six large Halibut caught on the hooks. Another mode of catching this and other flat Fish is to spear them on their sandy beds. No rule is laid down for this method of fishing; in some places it is carried on successfully by means of a common pitchfork. In other places a fine spear is used for the purpose—very long and with sharp prongs. THE THIRD GROUP OF SOFT-FINNED FISHES.
