Etheostoma duryi, nov. sps. Five specimens, 3 male and 2 

 female; length from 2 to 3 inches. Body stout, rather elongate, 

 somewhat compressed ; back arched ; profile regularly curved ; snout 

 obtuse; mouth small, horizontal, subterminal, maxillary, just reach- 

 ing orbit. Caudal peduncle curving slightly upward ; caudal fin 

 emarginate. Lateral line almost complete, following curve of dorsal 

 outline. Gill membranes broadly united. Fins large; dorsal fins 

 high, and scarcely connected; first dorsal with longer base than sec- 

 ond, but fin not so high; longest dorsal spine 1% times in head. 

 Cheeks, nape and opercles scaly. Eye, high up, as long as snout, and 

 contained 3^ times in head. 14 scales between dorsal and head, 

 crowded anteriorly. Premaxillary not protractile. 



Coloration in alcohol : 8 or 9 quadrate blotches along dorsum ; a 

 dark, broad band along the lateral line, on which are ten well-defined 

 quadrate blotches. Between the dark coloration of the dorsal and 

 lateral lines is a lighter area of orange (probably) in life. Belly orange. 

 A dark bar below the eye. The darker coloration is probably blue in 

 life. First dorsal fin dark along the base, with horizontal or diagonal 

 blotches, apparently orange in color, running up to top of fin, between 

 the rays ; second dorsal and anal with vertical orange stripes between 

 the rays ; pectoral and ventral fins plainer. 



Head 4^; depth 4^. Scales, 5-52-8. D. XL, n. A. II., 6. 



Etheostoma Formosa, nov. sps. One example, 2^ inches long 

 Body fusiform ; back regularly curved, not elevated ; head conical ; 

 mouth terminal, slightly oblique, moderate, maxillary reaching a little 

 beyond front of orbit. Lateral line nearly complete, following curve 

 of back. Gill membranes slightly connected ; premaxillary not pro- 

 tractile ; teeth on vomer ; jaws well armed with teeth. Eye as long 

 as snout, 4 in head. Dorsal fins separate, moderate ; base of first 

 dorsal longer than second, but fin not so high ; longest spine of dorsal 

 twice in head. Opercles and nape scaly ; cheeks and breast naked. 



Color in alcohol : 10 dark (blue?) bars or rings from dorsum to 

 belly, those on latter half of body completely encircling it; lighter, or 

 orange, interspaces ; cheeks and throat light, probably orange in life ; 

 opercles darker. First dorsal with upper half dark (blue?), lower half 

 lighter (orange?); second dorsal and anal fins mottled, probably blue 

 and orange; pectoral and caudal plain ; ventrals dark. 



Head3><; depth 4. Scales, 4-43-8. D. X., 13. A. II., 8. 



Cottus richardsoni Agassiz. One example, 3 inches long. Body 

 stout, tapering rapidly to caudal fin. Profile curved; vertex slightly
