If in head; caudal slightly emarginate ; pectorals short, not reaching tips 

 of ventrals, the two about equal in length, e([ua]ing head behind nostrils. 

 Body covered -with large, rough scales, everywhere spinous, but with a 

 tendency to smoothness on the breast ; ventral region completely and 

 uniformly scaled, without median series of enlarged plates, two or three 

 of which only are visible between the ventrals. Colors in life : Above 

 and on sides greenish, made very dark by fine, close-set, punctulations ; 

 two pairs of light streaks along sides, narrower than interspaces, becom- 

 ing yellowish in spirits; the upper pair from the nape ruuniDg along each 

 side of dorsal, inclosing between them a dusky streak occupying median 

 line of back ; the lower pair from above opercles running in a wavy course 

 above lateral line to upper caudal lobe; below this and bounded by it, 

 occupying the middle of the sides, is a broad dusky moniliform band ; 

 lower part of sides and ventral region light olive, dusted sparsely with 

 rather coarse black specks ; a small jet-black spot at base of caudal ; a 

 broad black bar (sometimes obscure) on head from snout through eye 

 across upper part of cheeks to opercular spine; sometimes a series of 

 small black cross blotches on median dorsal line ; fins translucent, barred 

 with dark lines. Length 4 or 5 inches. Western Kentucky and southern 

 Missouri, in clear, cold streams; not very common; one of the most 

 beautiful species. {Kv/ua, wave ; raivia, ribbon or stripe.)

Head 3i ; depth .5f to 6. D, XI or XII-13 or 14 ; A. II, 11 or 12 ; scales 

 11-74-16. Body elongate, terete, the sides somewhat compressed, becom- 

 ing more so posteriorly ; back elevated, the profile descending gently in an 

 unbroken line from front of dorsal to tip of snout. Head very long and 

 slender, much as in H. vmcrocephalns and H. phoxocepludus] the snout com- 

 paratively deep and narrow, abruptly rounded vertically at tip. Mouth 

 large, the cleft wide and slightly oblique, the maxillary reaching beyond 

 front of orbit, its length equaling distance from snout to front of pupil, 

 3i in head (the latter measured in this description to end of opercular 

 spine). Outer series of premaxillary teeth somewhat enlarged, the 

 bands all broad. Eye slightly less than snout, 5^ in head to end of oper- 

 cular spine; interorbital space convex transversely, its width about 5 

 diameter of eye. Cheeks perfectly smooth, with a few scattered, embed- 

 ded cycloid scales ; opercles and breast strictly naked ; nape and ventral 

 region closely scaled. Preopercular margin entire. Gill membranes 

 scarcely joined across the isthmus. Spinous dorsal short and high, the 

 first spine much shorter than the second, the seventh and eighth about 

 equal, the longest 2J in head; soft dorsal high, its base li in that of 

 spinous dorsal, the longest ray li in head ; anal similar to second dorsal, 

 but smaller; first anal spine short, the second but little longer, its length
