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 were taken from the Cheyenne River. One 
specimen from Valley City measured 34 inches long. Six from Lisbon 
measured as follows:

Moorhead, 1 specimen; Red Lake River at Crookston, 6. Color, light olive, 
with nine or ten very distinct dark bands around the sides.

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, 54 mm.; head, 13.5 mm.; depth, 
85 mm.; D. rx-14; A. 11-10; lateral line, 52. 
34. Etheostoma iowe 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). JWall-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 itis taken with 
hook and line, principally from below the dam. I see no reason why the 
multitude of fine 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. Perea flavescens (Mitchill). Yellow Perch; Ringed Perch. Forest River at 
Minot, common; Red Lake River at Crookston, common; Maple 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. Aplodinotus grunniens (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 (Linn:eus). Lawyer; 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 common.
