base ; ventrals not widely separated. Coloration extremely brilliant ; 

 dark olivaceous above, tessellated with dark ; sides with about 7 broad 

 transverse bars extending from below the lateral line on one side, across 

 the back, and down the other side; these bars are wider than the eye 

 and are connected along the lateral line by a faint black stripe ; in the 

 female these bars are black and the intervening spaces yellowish ; in the 

 male the bars are of a dark rich blue green, with metallic luster ; the 

 connecting longitudinal line greenish bronze; just above this line is a 

 luminous yellowish streak, and above, in each of the interspaces between 

 the bars, is a bright blotch of bronze-red; blackish green streaks down- 

 ward and forward from eye ; cheeks orange red, the color of iron rust ; 

 dorsal fin orange colored, with a bright bronze edge, a blackish spot on 

 the last rays ; second dorsal and caudal pale orange ; two bright yellow- 

 ish spots at base of caudal; anal bronze, with a blue-black shading; 

 ventral fins dark blue-black ; pectorals faintly orange. Males with the 

 rays of the ventral and anal fins covered with small corneous tubercles, 

 much as in some Cyprinidce. Female and alcoholic specimens show little 

 of the bright colors, although the same pattern is preserved. The spinous 

 dorsal has a dusky spot on its posterior rays, and the fins are destitute of 

 the dark bars found in related species. Length 2 to 3 inches. Indiana, 

 in the Wabash and Maumee basins, west to central Iowa and south- 

 ward in Arkansas, Kentucky, and Tennessee in the larger, clear streams; 

 especially abundant in the French Broad, the Wabash and in the Ozark 

 region ; not found east of the Alleghanies. There is considerable varia- 

 tion in coloration and in size of scales, those from the Tennessee Basin 

 especially having larger scales (52 to 65). One of the most brilliant of 

 all fishes, (evetdfa, comely.)

Head 4 to 4 ; depth 5 to 6 ; eye 4 to 4i in head, scarcely equal to snout ; 

 snout bluntish, 3i in head. D. XIII-13 or 14; A. 11,9; scales 7-68 to 

 70-17, pores 64 to 71. Body robust, rather compressed behind. Head 

 rather short. Mouth small, the lower jaw included; maxillary not 

 reaching the eye by about the width of the pupil ; preopercle more or 

 less distinctly serrate, especially in the young and in southern speci- 

 mens. Gill membranes broadly connected. Lateral line straight, com- 

 plete, not prolonged forward to the eye. Opercle covered with rather 

 large scales; cheeks with slightly smaller ones ; a triangular area on the 

 breast, in front of the ventral fins, with embedded scales; breast other- 

 wise almost naked ; throat naked ; scales persistent, those on middle line 

 of belly little enlarged and not caducous, except a few of the anterior 

 ones, 1 enlarged plate being present between the ventral fins ; body 

 otherwise covered with rather small ctenoid scales. Fins all very large ;
