in natural history, the name of a very singular American fish. It is broad, flat, and rounded; not very thick, and usually of about five or six inches long, and more than four broad. It has six fins, one large and long, one on the back, and another on the belly behind the anus; each of these reaches to the tail, and has toward the end a long string or cord, made of a single filament, that on the back-fin being longer than that on the belly; behind the gills it has also two fins of two fingers breadth long and one broad; and two others on the belly, which are very narrow; its head is small, and its mouth elevated and small, and furnished with small teeth; its scales are of a moderate size, and are half black and half yellow, so that the fish appears of a black colour, variegated with yellow half moons; its gills, and the beginning of its fins, are also yellow; and it has, on each side near the head, a yellow spot; it is eatable.
