Head 3i to 4^ ; depth 4J to 5. Snout short, as long as eye, 4 in head. 

 D. VIII to XI-9 to 12; A. II, 7 or 8; scales 6-48 to 60-12. Body rather 

 robust, the back not elevated, the sides somewhat compressed, the caudal 

 peduncle stout. Head rather short, the snout rather blunt, the anterior 

 profile somewhat decurved. Premaxillary not protractile. Mouth small, 

 oblique, the lower jaw somewhat included ; the maxillary extending to 

 front of eye, 3^ in head. Teeth rather large, close set. Preopercle entire. 

 Gill membranes rather broadly united. Opercular spine well developed. 

 Nape, cheek, opercles, and breast covered with small scales; these parts 

 rarely naked; body with moderate, ctenoid scales, those on belly simi- 

 lar; lateral line straight, its pores wanting only on the last 4 or 5 

 scales. Fins all low ; dorsal spines subequal, the longest about 3i in 

 head; soft dorsal well separated from spinous dorsal, its longest rays not 

 quite equaling head ; caudal fin rather large, If in head ; anal small, the 

 longest rays If in head, the spines small; pectorals 1^ in head ; ventrals 

 1|. Color in life dusky olive, with about 10 rather diffuse blackish cross 

 bands, most distinct just below lateral line, along which is a longitudinal 

 pinkish streak ; scales above with many dark punctulations, but with no 

 distinct spots; a dark bar below eye, and a horizontal dark streak 

 through it ; both dorsals and caudal barred with black in fine pattern, as 

 in E. flahellare, but less distinctly ; lower fins pale; no red or blue mark- 

 ings anywhere. This species varies excessively in squamation of head 

 and in size of fins ; nape, breast, and cheeks sometimes naked. Lower 

 Wabash Valley, Indiana, through western Kentucky and Tennessee to 

 Georgia and western Florida; abundant in sandy streams southward. 

 Specimens from Alabama (var. parvipinnis) are smaller, with lower fins 

 and fewer fin rays. D. XI-10; A. II, 7; scales 6-48-13. They seem to vary 

 perfectly into the typical form, {squama, scale; -ceps, head.)
