Colour, uniform pale-yellowish or olivaceous, no spots anywhere. Length 18 inches or less; weight, 3 to 5 pounds. There is a fourth species of this genus in American waters— I. meridionalis, known only from the Rio Usumacinta, in southern Mexico, but nothing is known of its game or food qualities, nor is it certain that the species is nae like Am- elurus dugest, a fork-tailed Amezurus. GENUS -AMEIURUS RAFINESQUE The Bullheads Body rather stout, the caudal peduncle much compressed ; head large and wide; mouth large, the upper jaw usually the longer; teeth in broad bands on the premaxillaries and dentaries; band on upper jaw convex in front, of uniform width, and without backward prolongation at angle; anal fin of varying length, with 15 to 35 rays; caudal fin truncate in most species, forked in some. Species several, swarming in every pond and sluggish stream in the Eastern United States and the Mississippi Valley; one or more species introduced on our Pacific Coast, where they are now abundant; one species occurring in China. The species are very variable and not easy to identify. The lack of connection between the supraoccipital and the interspinal buckler is the only charac- teristic by which this genus can be separated from /ctalurus. Most of the species are small, but they all possess a certain food value and some reach a large size. The species may be distinguished by means of the following key : a.
