81. Notropis jejumis, Forbes. 



(Bui. II, 60; Episema jejuna: Synop., 194; Minnilus jejunus.) 



A' species of the larger rivers, occurring in our collections only 

 from the Ohio, Iflinois, Wabash, and Mississippi, or at short dis- 

 tances from these streams, in lakes and tributaries immediately 

 connected with them. Not taken in Northern Illinois. 



82. Notropis megalops, Eaf . — Shiner ; Eed-fin ; Dace. 



(Bui II. 57; Luxilus cornutus: Synop., 186; Minnilus cornutus.) 



An extremely abundant fish, perhaps the commonest of the 

 cyprinoids ; most common in rivers and creeks and to the north- 

 ward, but also found in Southern Illinois, and occasionally in lakes 

 and ponds. 



83. Notrojyis whipplei, Grd. — Silver-fin. 



(Bui. II, 57; Photogenis analostanus: Synop., 178 and 179; 

 Cliola whipplei, Cliola analostana, etc.: M. V., 294; Luxilus 

 analostanus.) 



Most abundant in the northern part of Illinois, occurring princi- 

 pally in rivers and large creeks, but likewise rather common south- 

 ward. It is not unknown from the lakes, but we have found it al- 

 most strictly confined to running water. 



84. Notropis lutrensis, B. & G. 



(Bui. II, 57 ; Cyprinella forhesi: Synop., 174 and 175 ; Cliola 

 forbesi, Cliola lutrensis, etc. : M. V., 406 ; Cyprinella forhesi.) 



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 of this State. Along the Mississippi, 

 however, its range extends to extreme Northern Illmois. 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 Kiver 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. 



(Bui. II, 56 ; Alburnops Jmdsonius, Alhurnops storerianus: Synop., ^ 

 171; Cliola liudsonius: M. V., 290; Hybohsis 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 Eiver, and it has occurred likewise in in smaller streams from 

 the Calumet River, in Chicago, to the larger creeks in Union county.
