sleuder. Head moderately acute, the snout a little decurved, its length 

 rather less than eye. Mouth small, nearly horizontal, the lower jaw 

 included, the maxillary reaching to opposite front of eye, its length 4 in 

 head. Teeth rather small. Opercular spine strong. Gill membranes 

 scarcely connected. No black humeral scale. Cheeks, opercles, and nape 

 more or less closely scaled ; breast naked ; top of head without scales ; 

 scales smaller than in E. jessiw; lateral line straight, ceasing near the 

 middle of the body. Fins all low, the spines slender. Dorsal fins well 

 separated, caudal subtruncate ; pectorals 1^ to IJ in head. Fin rays 

 unusually variable. Color in life: Light green, finely blotched with darker; 

 dark-green blotches on opercle ; a dark stripe below eye ; sides with 10 or 

 11 reddish spots interspersed among darker bands ; spinous dorsal with a 

 narrow dark margin, below this a darker band and then a red one; soft 

 dorsal, caudal, and pectorals irregularly barred with yellow and with 

 greenish specks. Length about 2 inches. Upper Mississippi Valley from 

 Iowa and Nebraska, north to Assiniboia ; common northwestward, many 

 specimens having been taken by Dr. Eigenmann from Swift Current River in 

 the Saskatchewan Basin, and from Fort Qu' Appelle in the basin of the 

 Red River of the North, this last being the most northern point at which 

 any species of darter has yet been found. Dr. Meek records it as abun- 

 dant in Storm and Spirit lakes in Iowa, and in the State Fish Commis- 

 sion ponds at South Bend, Nebraska. It is the most common darter in 

 Nebraska and South Dakota (Evermann & Cox), its range extending as 

 far west as Valentine, Nebraska (longitude 100° 30'' W. ), the most westerly 

 point at which any member of the family has yet been found in the Mis- 

 souri Basin.

Head 4 ; depth 4f to 5. D. X to XII-12 to 14; A. II, 7 or 9; scales 6-47 

 to 55-8, lateral line usually but not always incomplete, pores developed 

 on about 35 to 38 scales. Body fusiform, rather deep and compressed; 

 head rather large and moderately pointed; mouth rather large, terminal, 



* This nominal species was described as follows: 



Head 3% to 4; depth 5 to b]4\ dorsal IX-9 or 10 ; anal II, 7, scales 3-53-10; pores 19. Eye 

 very large, much longer than snout, 3^4 in head; jawssubequal. Premaxillaries not protractile; 

 gill membranes scarcely connected; cheeks and opercles with a few scales; ventral line with the 

 median scales not enlarged; lateral line straight; palate without teeth; anal fin considerably 

 smaller than soft dorsal; humeral region without black scale; cheeks with a few scales just 

 below and behind eye; opercle with a few scales on its upper angle. Pectorals l}.^ in head; 

 caudal rounded. Color pale olive, with a lateral series of ill-defined large darker spots; in life 

 with about 8 dark-blue bars on side; alternating with rusty bars; dorsal and caudal fins barred. 

 Qu' Appelle River, a tributary of Assiniboine River, at Qu' Appelle, Assiniboia; one specimen 

 known, 44 mm. long. (Eigenmann; Boulenger). This is the northernmost point from which 

 Darters have been obtained. This species is veiy close to Etheostoma ioiDie and may not be differ- 

 ent, (qu' appelle, what calls? ; name of a river tributary to the Assiniboine.)
