F,G,J,K. Occasional to common in the lower Licking, Kentucky, Salt 
and Green River systems. Uncommon in the Cumberland River below 
Lake Cumberland. Usually replaces F. olivaceus in lowland swamps and 
ditches of region A. 
Fundulus notti (Agassiz). Starhead topminnow. A. Known from two 
localities in extreme western Kentucky: Open Pond, Fulton County (Sisk 
1973), and Murpheys Pond, Hickman County (Branson 1972). 
Fundulus olivaceus (Storer). Blackspotted topminnow. A,B,C,D,E. 
Abundant from the Tradewater River westward. Sporadic in the lower 
Green River where the few specimens available are somewhat inter- 
mediate in appearance between F. notatus and F. olivaceus. Specimens of 
this species reported from Martin’s Fork, Harlan County (Clay 1975) 
could not be located. 
Poeciliidae — livebearers 
Gambusia affinis (Baird and Girard). Mosquitofish. A,B,C,D,E,F, 
G,H,J,K. Abundant and ubiquitous in the Coastal Plain, the lower 
Green River and its tributaries, and the Salt River and other tributaries 
along the Ohio River, where it is presumed to be native. Probably in- 
troduced into the Kentucky, Licking and upper Cumberland Rivers for 
mosquito control. Several records are now available from the presumed 
areas of introduction.

southwestern Fulton County, where the species was first reported from 
Kentucky by Sisk (1973). 
Cottidae — sculpins 
Cottus bairdi Girard. Mottled sculpin. J,K,L. Unevenly distributed 
in the upper Kentucky and upper Licking rivers and region L. A record 
from Clear Creek, Rockcastle County (Branson and Batch 1972) needs 
verification. 
Cottus carolinae (Gill). Banded sculpin. D,E,F,G,H,J. Generally dis- 
tributed from the lower Cumberland River system eastward to and in- 
cluding the Kentucky river system, avoiding lowland areas in Region E.
