31. Notropis jejunus, Forbes. 
(Bul. II, 60; Episema jejuna: Synop., 194; Minnilus jejunus.) 
A species of the larger rivers, occurring in our collections only 
from the Ohio, Illinois, Wabash and Mississippi, or at short dis- 
sances from these streams, in lakes and tributaries immediately con- 
aected with them. Not taken in Northern Illinois. 
32. Notropis megalops, Raf.—Suiner, Rep-rin, Dacn. 
(Bul. II, 57; Luzilus cornutus: Synop., 186; Minnilus cornutus.) 
An extremely abundant fish, perhaps the commonest of the 
syprinoids; most common in rivers and creeks and to the north- 
ward, but also found in Southern Illinois, and occasionally in lakes 
and ponds. 
88. Notropis whipplet, Grd.—SIL7ER-FIN. 
(Bul. II, 57; Photogenis analostanus: Synop., 178 and 179; 
Cliola whipplei, Cliola analostana, etc.: M. V., 294; Luatlus 
analostanus.) . 
- Most abundant in the northern part of Illinois, occurring princi- 
pally in rivers and larger creeks, but likewise rather common south- 
ward. It is not unknown from the Jakes, but we have found it al- 
most strictly confined to running water. 
84. Notropis lutrensis, B. & G. 
(Bul. IE, 57: Cyprinella forbesi: Synop., 174 and 175; Chola 
forbesi, Gliola lutrensis, etc.: M. V., 406; Cyprinella forbest.) 
This active little fish delights in the rocky ripples of swift, small 
streams. It is essentially a southern species, and is much the most 
abundant to the southward in this State. Along the Mississippi, 
however, its range extends to extreme Northern Illinpis.. We found 
it in great numbers in some creeks in western Hancock county: 
The small, swift streams running down from the bluffs of the Mis- 
sissippi River are its favorite haunts. A few specimens have been 
taken in the Illinois, but it is not known from the lakes, from the 
Wabash region, or from the small interior streams. 
85. Notropis hudsonius, Clinton,—SpawN-EATER. 
(Bul. II., 56; Alburnops hudsonius, Alburnops storerianus: Synop., 
171; Cliola hudsonius: M. V., 290; Hybobsis hudsonius.) 
Common everywhere to the northward, especially in Lake Michi- 
gan and the smaller lakes of Northern Illinois. Collected to our 
extreme southern limits, but not abundant south of the central part 
of the State. Next to the lakes we have found it most abundant in the 
‘Illinois River, and it has occurred likewise in smaller streams from 
the Calumet River, in Chicago, to the larger creeks of Union county.
