abundant; Maple River at Mapleton, 6; Buffalo River at Hawley, abundant; 

 Goose River at llillsboro, abundant; Mouse River at Minot, plentiful; Eng- 

 lish Cooley at (Jrand 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 tlu^ boards 

 of the dam, whore they Avonld rcmiiin ibr several hours. 



8. Moxostoma macrolepidotum dnquesnii (T.e Sueur). Iledhorse; 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. 



9. Notropis megalops (Rafmesque). Common Shine)-. Otter Tail River at Brecken- 



ridge, abundant; Red River of 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 Cyprinid:e, and thrives equally well 

 in all parts of the great range over which it is distributed. 



10. Notropis delicio.sus (Girard). Otter Tail River at Breckeuridge, 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. 



11. 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. 



12. Notropis atherinoides Rafmesque. Pembina River at Neche, 1 specimen ; Red 



Lake River at Crookston, 25. Specimens from Crookston average 2i inches 

 in length. This species was taken in abundance by Dr. Eigenmann farther 

 north. 



13. Notropis whipplii (Girard). Cheyenne Kiver 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 1+ 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
