INVESTIGATIONS IN MINNESOTA AND NORTH DAKOTA. 373 



from a gravelly ripple where the water was not over 2 inches deep. The 

 largest and finest specimens Avere taken from the Cheyenne River. One 

 specimen from Valley City measnred 3;^ inches long. Six from Lisbon 

 measured as follows : 



33. Etheostoma guntheri Eigenmann & Eigeumann. Red River of the North at 

 Moorhead, 1 specimen; Red Lake River at Crookston, 6. Color, light olive, 

 with nine or ten very distinct dark bands around the sides. 

 Measurements of 5 specimens from the Red Lake River are as follows: 



The large specimen from the Red River of the North differs very mate- 

 rially from the smaller in color, agreeing, however, in the marking on the 

 anterior dorsal. The rays differ somewhat, and the scaling of the cheeks is 

 not the same in that the specimen from the Red River of the North has 

 cheeks covered with large scales. Length, 51 mm, ; head, 13.5 mm. ; depth, 

 85 mm.; D. ix-14 ; A. ii-lO; lateral line, 52. 



34. Etheostoma iowae Jordan & Meek. Cheyenne River at Valley City, 1 speci- 



men; Cheyenne River at Lisbon, common; Red Lake River at Crookston, 5; 

 Park River at Grafton, 6. 



35. Stizostedion vitreum (Mitchill). Wall-eye; Pike Perch. Otter Tail River at 



Breckenridge, 1 specimen; Cheyenne River at Valley City, 6; Red River of 

 the North at Grand Forks, rare; Red Lake River at Grand Forks, rare; Red 

 Lake River at Crookston, 8. The last-named place is the only locality 

 visited where the local fishermen report this species plentiful enough to 

 furnish any considerable amount of food. From this stream it is taken with 

 hook and line, })rincipally from below the dam. I see no reason why the 

 multitude of line lakes throughout the State of Minnesota should not be 

 stocked with this fine food-fish, since it could be done at comparatively small 

 cost. 



36. Perca flavescens (Mitchill), Yellow Perch; Pinged Perch. Forest River at 



Minot, common; Red Lake River at Crookston, common; Majile Creek at 

 Mapleton, 5 specimens. Not frequently taken in the streams, but said to be 

 found in nearly all the lakes of the State. 



37. Aplodinotusgrunniens (Rafinesque). Fresh-water Drum; Grunter; Sheepshead. 



Red Lake River at Crookston, 2 specimens. Not common; the fishermen 

 seem to have but little knowledge of it. 



38. Lota lota maculosa (Linna'us). I^awyer; Ling. Red River of the North at 



Moorhead, 1 specimen ; Red Lake River at Crookston, 3. The one specimen 

 from Moorhead was large, about 18 inches long, while those from Crookston 

 were small. Occasionally taken on a "trot line" from the Red River, but 

 not commou.
