Illinois, it occupies a subordinate place amonf? our cyprinoids. It is common- 

 est in the extremes of the State, occurring but rarely throughout the central 

 prairie region. 



81. Notropis jejunus, Forbes. 



(Bui. 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 distances from these 

 streams, iu lakes and tributaries immediately connected with them. Not 

 taken in Northern Illinois. 



82. Notropis megalops, Raf.— Shiner; Redfin; Dace. 



(Bui. 11,57; 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 northward, but also found in 

 Southern Illinois, and occasionally in lakes and ponds. 



83. Notropis 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 principally in 

 rivers and large creeks, but likewise rather common southward. It is not 

 unknown from the lakes, but we have found it almost strictly confined to 

 running water, 



84. Notropsis lutrenis, B. & G. 



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



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



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 Illinois. We found it in great numbers in some creeks 

 in western Hancock county. The small, swift streams running down from 

 the bluffs of the Mississippi 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 Jmdsonius, Clinton. — Spawn-eater. 



(Bui. II, 56; Albiirnops hudsonius, Alburnops storerianits: Synop., 171; 

 Cliola hudsonius: M. V., 290; Hybobsis hudsonius.) 



Common everywhere to the northward, especially in Lake Michigan 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 occur- 

 red likewise in smaller streams from the Calumet River, in Chicago, to the 

 larger creeks in Union county. 



86. Notropis phenacobius, Forbes. 



Very rare, at Peoria; not seen elsewhere. 



87. Notropis slramineus, Cope. — Straw-colored Minnow. 



(Bui. II, 57; Alburnops slramineus: Synop., 167; Cliola stramineus: M. 

 v., 291; Hybopsis stramineus.) 



This species is rare in our collections, and has occurred only in rivers and 

 small streams in Central and Northern Illinois.
