in Ichthyology, is a fish of the mustela kind, commonly called the fossile myzela, or fossile-fish. This fish is generally found as long as an ordinary man's hand is broad, and as thick as the finger; but it sometimes grows much longer: the back is of gray, with a number of spots and transverse streaks, partly black and partly blue; the belly is yellow, and spotted with red, white, and black; the white are the larger, the others look as if they were made with the point of a needle; and there is on each of the sides a longitudinal black and white line. There are some fleshy excrescences at the mouth, which are expanded in swimming; and when out of the water, they are contracted. These fishes run into caverns of the earth, in the sides of rivers, in marshy places, and penetrate a great way, and are often dug up at a distance from waters. Often, when the waters of brooks and rivers swell beyond their banks, and again cover them, they make their way out of the earth into the water; and when it deserts them, they are often left in vast numbers upon the ground, and become a prey to swine. It is thought to be much of the same kind with the figum fish; and it is indeed possible that the pacilia of Schonefeldt is the same.
