line slightly curved, complete, with about 38 to 41 scales. The two speci- 
mens from the lake were somewhat darker and richer in color, with body and 
caudal peduncle more slender. These specimens are of the form described 
recently by Eigenmann & Eigenmann as Notropis scopifer. 
Hybopsis kentuckiensis (Rafinesque). iver Chub. Little Minnesota River 
at Browns Valley, 2 specimens, both small. This species apparently does 
not thrive in these waters as it does farther south. 
Percopsis guttatus Agassiz. Trout Perch. Little Minnesota River at Browns 
Valley, rare; Big Stone Lake at Creager’s farm, 20 specimens. This is 
apparently the most common species of small fish at the last-named place, 
where it is highly prized for bait by the local fishermen. It was taken near 
shore in about 4 feet of water and usually from over a sandy bottom. 
Fundulus diaphanus (Le Sueur). Mud Minnow; Top Minnow. Big Stone Lake 
at Creager’s farm, 7 specimens; Big Stone Lake at Ortonville, 12, taken in 
shallow water near the shore. Ovaries of females filled with eggs, some of 
which were ripe, while others were very small: The intestinal canal was 
filled with a peculiar pin-shaped parasite about a quarter of an inch long. 
Lucius lucius (Linnzeus). Northern Pickerel; Pike. Little Minnesota River at 
Browns Valley, 8 large specimens; Big Stone Lake at Ortonville, 3; Big 
Stone Lake at Creager’s farm, 12. Thisis the most abundant food fish of this — 
region. 
Bucalia inconstans (Kirtland). Brook Stickleback. Big Stone Lake at Orton 
ville. This species does not inhabit the lake to any extent. 
Pomoxis annularis Rafinesque. Red-eye; Straw Bass; Calico Bass. Big Stone 
Lake at Creager’s farm, common. An excelient food-fish, thriving in these 
waters. 
Lepomis pallidus (Mitchill). Big Stone Lake at Ortonville,common. Great 
numbers are taken with hook and line; worms or insects are used for bait. 
Lepomis megalotis (Rafinesque). Blue-gill. Taken only at Ortonville. Num- 
bers and habits about the same as those of L. pallidus. Several young speci- 
mens taken with the seine. 
Micropterus dolomieu (Lacépéde). Small-mouth Black Bass. Little Minnesota 
River at Browns Valley, 3 specimens ; Big Stone Lake at Creager’s farm, 5. 
This species was not abundant and only very small specimens were taken. 
Micropterus salmoides (Lacépéde). Large-mouth Black Bass. Little Minnesota 
River at Browns Valley, common; Big Stone Lake at Creager’s farm, 12 
specimens ; Big Stone Lake at Ortonville, common. One of the most abun- 
dant game fishes and one to which the lake seems particularly well adapted. 
Etheostoma aspro (Cope & Jordan). Black-sided Darter. Little Minnesota 
River at Browns Valley, 5 large specimens. Head 4 ; depth 54 ; dorsal 1x or 
x-11 or 12 ; anal 11,7. 
Etheostoma nigrum Rafinesque. Little Minnesota River at Browns Valley, 2 
specimens; Big Stone Lake at Creager’s farm, 15; Big Stone Lake at Orton- 
ville, common. Color dark. Head and shoulders heavy, tapering to the 
long caudal peduncle; cheeks and opercles covered with scales; lateral line 
with 40 to 52 scales. A specimen from the outlet of Big Stone Lake is some- 
what peculiar and may be described as follows: Head, 34 (without flap, 34); 
depth, 52; eye, 44 (4 without flap), equaling snout. D. vim-12; A. 1, 8; 
scales 4-49-5. Body slender, resembling Ltheostoma olmstedi in general form, 
head moderate, caudal peduncle long and slender; mouth large, nearly hori- 
zontal; premaxillaries protractile; maxillary reaching vertical of pupil; 
gill-membranes scarcely connected. Cheeks naked or nearly so; opercles, 
nape, and breast scaled, belly with ordinary scales; lateral line complete, 
slightly arched in an anterior portion. Dorsal fin high, longest spine about 
12 in head, soft portion a little higher; anal rays about 2 in head, anal fin 
smaller than soft dorsal; its base 13 in that of soft dorsal; pectoral long, as_
