abundant; Maple River at Mapleton, 6; Buffalo River at Hawley, abundant; 
Goose River at Hillsboro, abundant; Mouse River at Minot, plentiful; Eng- 
lish Cooley at Grand Forks, common; Pembina River at Neche, rare; Park 
‘River at Grafton, 7. This species was taken from almost every tributary of 
the Red River of the North, but was not found in the main stream. I was 
told by the miller at Hawley that great numbers of the young of this species 
would come almost every day and fasten (suck) themselves onto the boards 
of the dam, where they would remain for several hours. 
8. Moxostoma macrolepidotum duquesnii (Le Sueur). MLedhorse; White Sucker. 
Red River of the North at Moorhead, abundant; Cheyenne River at Lisbon, 
common; Cheyenne River at Valley City, abundant; Buffalo River at Haw- 
ley, 10 specimens; Red River of the North at Grand Forks, rare; Red Lake 
River at Grand Forks, common; Park River at Grafton, rare; Red Lake River 
at Crookston, abundant. This species prefers clear water. It is rare in the 
Red River of the North, but common in Red Lake River; even near its 
mouth, at Crookston, it is very abundant, the seine landing 8 or 10 large 
specimens at a haul.

ridge, abundant; Red Riverof the North at Moorhead, rare; Cheyenne River 
at Lisbon, plentiful; Cheyenne River at Valley City, common; Maple River 
at Mapleton, abundant; Buffalo River at Hawley, abundant; Goose River at 
Hillsboro, plentiful; English Cooley at Grand Forks, not abundant; Pem- 
bina River at Neche, common; Forest River at Minot, common; Red Lake 
River at Crookston, abundant. This species appears to adapt itself to all 
conditions of temperature, water, food supply, etc., since it is one of the 
most widely distributed species of the Cyprinide, and thrives equally well 
in all parts of the great range over which it is distributed. 
Notropis deliciosus (Girard). Otter Tail River at Breckenridge, 28 specimens; 
Cheyenne River at Valley City, common; Mouse River at Minot, 15; Pem- 
bina River at Neche, abundant; Forest River at Lisbon, common; Red Lake 
River at Crookston, common. These specimens, when compared with others 
from the Mississippi Valley, show no very marked modifications, except 
possibly the bodies are somewhat stouter. Largest specimens average 2 
inches long. . 
Notropis dilectus (Girard). Otter Tail River at Breckenridge, 1 specimen; 
Cheyenne River at Lisbon and Valley City, common; Buffalo River at Haw- 
ley, rare; Red River of the North at Grand Forks, rare; Red Lake River at 
Crookston, 2. Specimens from Red Lake River were in the best color, and 
hence more like individuals of this species found in the Mississippi Valley. 
Those from the Red River of the North were very light, almost translucent. 
Specimens from the Cheyenne were in good color, the head, sides below 
lateral line, dorsal, caudal, and pectoral washed with red. 
Notropis atherinoides Rafinesque. Pembina River at Neche, 1specimen; Red 
Lake River at Crookston, 25. Specimens from Crookston average 24 inches 
in length. This species was taken in abundance by Dr. Eigenmann farther 
north. 
Notropis whipplii (Girard). Cheyenne River at Lisbon, common. Although 
home of this species is much farther south, it varies as little in color and 
markings as any other fish of this region, remaining almost true to the type. 
14. Notropis cayuga Meek. Buftalo River at Hawley, rare; Maple River at 
Mapleton, 8 specimens; Cheyenne River at Lisbon, 5; Cheyenne River at 
Valley City, 6. Specimens in this valley average only about 14 inches long. 
The colors are good, the lateral line quite black, just wide enough to cover 
one row of scales, and quite distinct over opercle and around snout; no 
vertebral stripe; scales in lateral line 36; these have a peculiar notched
