Hybopsis dissimilis (Kirtland). Streamline chub. D,F,G,H,J,L. Oc- 
casional in the high gradient parts of the Cumberland, Green, Barren, 
Rolling Fork, Kentucky and Big Sandy River systems. I am unaware of 
confirmed records from the Licking River drainage although the species 
probably occurs there. 
Hybopsis gelida (Girard). Sturgeon chub. Presently known from one 
locality, near the mouth of the Ohio River (Pflieger 1975). Numerous at- 
tempts to collect this species farther south in the Kentucky part of the 
Mississippi River have been unsuccessful. It is clearly part of the Ken- 
tucky fauna since it also occurs as far south in the Mississippi River as 
Mississippi. 
Hybopsis gracilis (Richardson). Flathead chub. Known from only 
two localities, both in the main channel of the Mississippi River, where it 
is uncommon. 
Hybopsis insignis Hubbs and Crowe. Blotched chub. C,H. Unknown 
from region C since its original description by Hubbs and Crowe (1956) 
and the subsequent impoundment of the lower Tennessee River. Rare in 
the upper Cumberland River where it has been taken at four localities. 
Hybopsis meeki Jordan and Evermann. Sicklefin chub. Presently 
known from only one locality, at the confluence of the Ohio River with 
the Mississippi River (Pflieger 1975, Smith 1979). It has been taken 
farther south in the Mississippi River (Bailey and Allum 1962), so is 
clearly part of the Kentucky fauna. 
Hybopsis storeriana (Kirtland). Silver chub. C,D,E,F,G,H,J,K,L. 
Generally distributed in large and medium-size rivers throughout the 
state, including the main channels of the Ohio and Mississippi rivers 
where it is the most common Hybopsis. 
Hybopsis x-punctata Hubbs and Crowe. Gravel chub. Known from 
only three localities in the Ohio River in Campbell, Greenup and Boyd 
counties (Trautman 1957); needs substantiation. 
Nocomis biguttatus (Kirtland). Hornyhead chub. J. Known from 
three localities in Franklin County (UMMZ, UL, CU). Lachner and 
Jenkins (1971) suspected that the isolated Kentucky River population of 
this species was perhaps the result of a bait or stocking introduction. 
Nocomis effusus Lachner and Jenkins. Redtail chub. D,F,H. 
Occasional in the Cumberland River between Cumberland Falls and the 
Little River system. Rare in the upper Green River drainage where it is 
known from two localities. Extensive collecting in the lower Green River 
has not revealed the presence of this species, despite the suggestion by 
Lachner and Jenkins (1967) that it might occur there. 
Nocomis micropogon (Cope). River chub. H,J,K,L. Common in the 
upper Cumberland, upper Kentucky and Licking River systems. 
Occasional in region L. 
Notemigonus crysoleucas (Mitchill). Golden shiner. A,B,C,D,E, 
F,G,H,J. Generally distributed in the western two-thirds of the state. A
