Gradually passing from Indiana westward into the slight variety 



1477a. ETHEOSTOMA CCERULEUM SPECTABILE (Agaasiz). 



Head 4; depth 4*. D. X-12; A. II, 7; scales 5-40-7 ; lateral line ou 

 20-25 scales. Very similar to ccvruJeum, but more elongate and rather 

 more compressed ; the colors similar, but the upper portion of the sides 

 with distinct blackish stripes along the rows of the scales, and the 

 ground color of the back and sides having a peculiar whitish or bleached 

 appearance. The two dorsal fins usually well separated. Scales usually 

 present below and behind eye. Length 2 to 3 inches. Mississippi Valley ; 

 rather less abundant than the other and ascending small or even muddy 

 streams ; not always to be distinguished with certainty from the pre- 

 ceding. Both occur in Indiana and Illinois, but the form called .spectaUle 

 is the only one seen in streams of Missouri. (spectaMlis, conspicuous.) 



PtKcilichlhi/s spectabilis, Agassiz, Amer. Journ. Sci. and Arte, 1854,304, Osage River, Missouri, 

 (Coll. Geo. Stolley); Jordan & Gilbert, Synopsis, 518, 1883. 



1478. ETHEOSTOMA LEPIDUM (Baird & Girard). 



Head 4i ; depth 4f . D. IX-11 to 13 ; A. II, 6 to 8 ; scales 6-48 to 54-8, 

 pores 27 to 36. Body rather stout, compressed, tapering backward. 

 Head subcorneal. Mouth moderate, with equal jaws ; maxillary reaching 

 front of orbit. Eyes large. First dorsal rather low ; dorsal fins some- 

 what connected. Head, as well as throat and neck, entirely scalelese. 

 Color olivaceous, with some dark-blue bars; scales dusky at base, some- 

 times a slight trace of a humeral spot ; dorsals and caudal mottled or 

 barred. Length 2i inches. Streams of Arkansas, Texas, and Chihuahua • 

 common ; apparently gradually passing into Ethcostoma caruleum, from 

 which only the naked head separates it. Gilbert regards it as a sub- 

 species of cawuleum. (lepidus, j)retty.)
