INVESTIGATIONS IN MINNESOTA AND NORTH DAKOTA. 357 
sides, belly, and jaws dashed with carmine red, through which a silvery 
pigment shows. This is one of the most abundant species found in the 
boxes of the fish-ladder, and collected about the opening or foot of it. The 
one specimen taken at Ortonville differs somewhat from the other specimens. 
The head was more sharply pointed; back not elevated; belly decurved; 
lateral line parallel with belly; vertebral stripe narrow but distinct; lat- 
eral stripe wide and of a deep metallic blue; sides below lateral line washed 
with red. Scales in lateral lines, 40; scales before dorsal, 14. 
Notropis megalops(Rafinesque). Common Shiner; Silversides. Minnesota River 
at Ortonville, common; Minnesota River at Montevideo, abundant; Wheat- 
stone Creek at Millbank, abundant; Pomme de Terre River at Appleton, 
common; Chippewa River at Montevideo, common. ‘This species is widely 
distributed and was very abundant at every station visited. 
. Notropis heterodon (Cope). Pomme de Terre River at Appleton, common; 
Wheatstone Creek at Millbank, 19 specimens. 
. Notropis scopifer Eigenmann & Eigenmann. Pomme de Terre River at 
Appleton, 1 specimen. 
. Rhinichthys cataractz dulcis (Girard). Dace. Pomme de Terre River at 
Appleton, 2 specimens. Length, 24 inches. Color, very dark. 
Hybopsis kentuckiensis (Rafinesque). Taken at every station in the Minne- 
sota Valley, but the individuals were neither large in size nor abundant in 
numbers. There are some external differences in the specimens from 
various stations. Those from the Minnesota River at Ortonville were all - 
young and light in color; those from the more stagnant waters of Wheat- 
stone Creek are larger and quite dark; while the sides and bellies of many 
of the specimens from the Pomme de Terre are marked with large, dark spots. 
Semotilus atromaculatus (Mitchill). Horned Dace; Creek Chub. Minnesota 
River at Ortonville, 4 specimens; Wheatstone Creek at Millbank, 4; Pomme 
de Terre at Appleton, abundant; Chippewa River at Montevideo, 12 speci- 
mens. This species, while far from being as abundant here as in the Middle 
and Southern States, was more plentiful than the last-named species. 
Notemigonus chrysoleucus (Mitchill). Golden Shiner. Minnesota River at 
Ortonville, 1 specimen; Wheatstone Creek at Millbank,5. A rare species, 
but the specimens are large and in fine color. 
Percopsis guttatus (Agassiz). Trout Perch. Minnesota River at Montevideo, 
3 specimens. Specimens from this locality are not so hardy as those taken 
from the lake. 
Fundulus diaphanus (Le Sueur). Mud Minnow; Top Minnow. Minnesota 
River at Ortonville, 2 specimens; Wheatstone Creek at Millbank,5; Pomme 
de Terre River at Appleton, common; Chippewa River at Montevideo, 7; 
Minnesota River at Montevideo, common. This species prefers the more 
quiet waters, and was not taken from ripples or swift currents. 
Lucius lucius (Linneus). Pike; Northern Pickerel. Minnesota River at Orton- 
ville, 10 specimens; Wheatstone Creek at Millbank, common; Pomme de Terre 
at Appleton, 6; Chippewa Riverat Montevideo, 15; Minnesota River at Mon- 
tevideo,4. While this species prefers the lakes, it is by no means confined to 
these waters, but is common in streams and very abundant in the Chippewa 
River and Wheatstone Creek. It ascends the latter stream from Big Stone 
Lake, since the water connection during high water is almost direct. 
Eucalia inconstans (Kirtland). Brook Stickleback. Minnesota River at Orton- 
ville, specimens very small and poorly colored. 
Ambloplites rupestris (Rafinesque). Rock bass; Goggle-eye; Red-eye. Minne- 
sota River at Ortonville, 3 specimens; Pomme de Terre River at Appleton, 
10; Chippewa River at Montevideo, 7; Minnesota River at Montevideo, 2. 
An excellent food-fish, thriving well in the lakes, but not taken in quantities 
from the streams.
