30. Hybopsis kentuckieiisis ( Rafiuesque). Chub. A ft)\v specimens from the Elkhoru at Fremont. 
31. Hybop,sis storerianu.s ( Kirtland). This species was found to he common in tlie Elkhorii at 
Fremont, Nebr., and scarce in Floyd River at Sioux City, Iowa. No specimens were taken 
from other localities. 
32. Hybopsis hyostomus Giliiert. Found in Platte and Elkhorn rivers at Fremont, and Bine River 
at Crete. Appareutlj" scarce in all of these places. 
33. Platygobio gracilis (Richardson ). Flat-headed Minnoir. A few small s])ecimens were found in 
Platte River at Fremont. 
34. Semotilus atromaculatus (Mitchill). Creek Chub. Floyd River at Sionx City, scarce; more 
common in College Creek at Ames. 
35. Notemigonus chrysoleucus (ilitchill). Itreani. Platte River near Fremont, Floyd River at 
Sionx City, College Creek at Ames, and Storm and Spirit lakes, in all of which waters this 
species is common. 
36. Hiodoii alosoides (Ralinesipie). Moon-eye. A few taken in Platte River at Fremont and Floyd 
River at Sionx City. 
37. Dorosonia cepediamim (Le Sueur). Hickory Shad. A common species in the Elkhorn River in 
suitable places at Fremont, hnt less so in the Floyd River at Sioux City. 
38. Percopsisguttatus Agassiz. TroutPerch. Fonndhy us only in Floyd River at Lemars and in East 
Okohoji Lake, from which latter place four specimens were obtained November 2, 1892, from a 
niinnott box at one of the summer hotels. Mr. H. C. Owen, proprietor of the Lake Park 
House at Spirit Lake, says that this curious fish is abundant in the lakes in that vicinity and 
that it is used extensively for live bait. Professor Meek, in .Tune, 1890, made special investi- 
gation in East Okobpji Lake for this species, but was unable to find it. The specimens 
obtained by mo vary in length I'rom to 5 inches. In Mill Creek, .a small tributary of the 
Little Sioux River, which is the outlet of the Spirit Lake group. Professor Meek found 
Percopsis yidtatus to be the most abundant species. In these specimens the serrations of the 
preoperclo are much more pronounced than in specimens from the I.ittle Miami River, Ohio, 
with which I have compared them. (Evermanu.) 
39. Fundulus zebriiius .Jordan & Gilbert. Common in Storm and East Okoboji lakes. It wdll 
doubtless be found to occur in all the lakes of Iowa and southern Minnesota. 
40. Zygonecte.s sciadicris (Cope). Specinieus were obtained from the Platte and Elkhorn rivers at 
Fremont, and 2 young individuals from Floyd River at Lemars. It seems to be very scarce at 
each of these places. This species and Z. macdomddi Meek very closely resemble each other, 
although the specimens so far collected show constant, but slight dilfereuces. In Z. sciadicns 
the teeth in the upper jaw are in a broad band with the outer ones but little enlarged, and 
their tips but slightly hooked. Dorsal raj?s, 10; anal, 11. Z. macdonaldi has the teeth of the 
upper jaw in a narrower band with the outer ones considerably enlarged and decidedly 
hooked. Dorsal rays, 11 or 12; anal, 13. 
41. Luciuslucius (Linuajus). Pike ; Xorthern Pickerel. Found in Floyd River at Lemars and Sioux 
City, where it was common ; in Storm Lake, where it is the most abundant and most important 
food and game lish; also in East and West Okoboji and Spirit lakes, in each of which it is 
abundant, being second in importance only to the wall-eyed pike {Stizostedion vitreum). 
42. Pomoxis sparoides (Lacepede). Calico Bass. Specimens of the calico bass were identified 
at East Okoboji Lake, in which it is said to be a common species. 
43. Ambloplites rupestri.'s (Rafines(pie). Goggle-eye. A few specimens were obtained at Sioux City 
in Floyd River. 
44. Lepomi.s cyanellus (Radnesque). Green Sinitish. Common in the ponds of the Nebraska State 
dsh-hatchory at South Bend; also in Platte and Elkhoru rivers at Fremont, Floyd River at 
Lemars, and in Storm Lake. 
15. Lepomis humilis (Girard). Common at South Bend, Nebr., in tlic i>ouds of the State dsh- 
hatchery ; also in Platte and Elkhorn rivers at Fremont, Salt Creek near Lincoln, Floyd 
River at Lemars and Sioux City, Blue River at Crete, and in Storm Lake. 
46. Lepomis pallidus (Mitchill). Bine Snnjish. Found in Spirit Lake, and doubtless occurring in 
the other lakes of that group. 
17. Lepomis gibbosus (Liuu;eus). Common Snnjish. Specimens obtained from Spirit Lake, where 
it does not aq>pear to be at all common.
