Maxillary reaching front of orbit. Eye large, considevablj' longer than snout, 3 iu head, 
greater than iuterorbital. Origin of dorsal over ventrals, equidistant from tip of snout and 
from base of upper caudal rays; longest ray scarcely extending beyond tip of last when 
depressed. Anal low, the longest ray not extending past tip of last ray when the tin is 
depressed, equal to snout and eye. Ventrals reaching vent, slightly longer than the highest 
anal ray. Pectorals little longer than head less opercle. Scales closely imbricated, the exposed 
edges considerably deeper than long in the largest specimens. Lateral line decurved, com- 
plete. Breast uahe<l (scaled iu N. topeka). A dark streak from anal to caudal, lower parts 
otherwise plain. A dark vertebral line, a plumbeous band along the sides, a faint spot at 
the base of the caudal .about as large as the pupil. A series of spots along each side of the 
lateral line. Upper parts of sides .and the back jirofiisely spotted, the edges of the scales black, 
giving the whole part a reticulated appearance. The specimens from Qu’Appelle are darker 
than those from Brandon. 
20. Notropi.? deliciosus (Girard). Three specimens of this species were taken at Winnipeg. 
21. Notropis megalops (Eatinesque). A number of specimens of this species were obtained at 
Brandon. None were seen elsewhere. 
22. Notropis scopiferus Eigenmann & Eigenmaun. This species is evidently closely related to W. 
Inciodits, from which it differs iu the scaling and in having a conspicuous jet-black spot about 
as large as the pupil at the base of the caudal lin. Numerous specimens were obtained at 
Winnipeg, Brandon, Fort Qu’Appelle, and Medicine Hat. The species is most abundant at 
Fort Qu’Appelle, where the largest specimens (112 mm. ) were obtained. Head, 4-41- (longest in 
young); depth, 4^; D. 9-1; A. 104 (the first two rays minute, uusegmented, and uubr.auched) ; 
scales, 6-36 to 42-4; 14 to 18 scales in front of the dorsal; teeth, 2, 4-4, 2; grinding surface 
very narrow, on two teeth. Compres.sed fusiform, the dorsal and ventral outlines about 
equ.ally .arched; highest point of back at lirst dorsal ray. Head heavy, compressed, fiat 
above; snout blunt, much decurved. 4Iouth sm.all, little oblique; the premaxillary below 
the level of the lower margin of the pupil; maxillary extending to anterior margin of eye. 
Eye large, longer than snout, 3 in head, little less than interorbital width. Origin of dorsal 
about equidistant from tip of snout .and base of caud.al; the highest ray extending much 
beyond tip of last when the fin is depressed, equal to the length of the head; caudal deeply 
forked, the lobes equal, longer than head. Anal similar to dorsal, but much lower, the 
highest ray about equal to the head less the suout; ventrals below the dorsal, reaching veiit; 
pectorals about equal to the highest anal ray. Scales closely imbricated, but not notably 
deeper than long. Lateral line complete, and each scale with a well-developed tube. The 
line evenly and gently decurved to above origin of anal. All specimens, from the smallest 
(.about 25 mm. long) to the largest, have a conspicuous black spot at the base of the middle 
caudal rays, a silvery lateral band, its dorsal margiu distinct, its lower margin not distinct. 
Color otherwise variable; those from muddy water (Red River at Winuipeg) are bright 
silvery with very little dusky, the chromatophores being not less numerous, but contracted. 
The other extreme is found iu the clear water of the Qii’A^rpelle. In these specimens there 
is a conspicuous vertebr.al baud, and all the scales above the lateral line are most profusely 
dotted with black, the ilots being largest at the margins of the sc.ales. Top of head and upper 
parts of its sides similarly dotted. Dorsal, c.audal, and upper parts of pectorals dusky. Speci- 
mens from Little Traverse Bay, Lake iMichigan, seem to represent a variety of the species 
above described; the snout is more slender, the eye iierceptibly smaller, and the c.audal 
peduncle more slender. The difference is more marked in young examples, the form being 
]uuch more slender than iu scopiferus and the caudal spot notably smaller. 
23. Notropis jejunus (Forbes). This species was found to be abundant at Winnipeg, Brandon, and 
Medicine Hat. The teeth are quite variable, being in different specimens 4—4; 1, 4-4, 2; and 
2, 4-4, 2; otherwise there is little or no variation. It is not unlikely that some of the species 
described as having teeth 4-4, or 1, 4-4, 2 are identical with this species. 
24. Notropis atherinoides (Eafinesque). Winnipeg, iMediciue Hat, Poplar. The specimens from 
Winnipeg are slightly deeper than those from other localities, and all of the northern speci- 
mens have slightly larger eyes and correspondingly shorter snou.' *'
