Kentucky Fishes 
55 
have been recognized for more than 20 years and their distributions are 
accurately known. 
I have not departed from the 1970 list of names even though recent 
studies (some unpublished) reveal that the names of some Kentucky 
fishes are affected. Fundulus notti will probably be accepted for F. dispar 
(Wiley 1977); Menidia audens will probably be changed to M. beryllina. 
Although several studies indicate that Notropis chrysocephalus 
intergrades or hybridizes extensively with N. cornutus in various parts of 
its range, I have followed Gilbert (1961) in using the name N. 
chrysocephalus for the Kentucky populations. The Kentucky population 
hitherto known as Percina uranidea should now be called P. ouachitae 
(Williams and Etnier 1977). 
I divided Kentucky into 11 subunits, which correspond to river 
systems, or fish faunal blocks (Fig. 1). For each species, letters denoting 
the Kentucky subunits in which it is known to occur follow directly after 
the common name, which is followed by a concise statement regarding 
the species’ current or former distribution in the state. For species re- 
stricted to the large bordering Ohio and Mississippi rivers, designation of 
subunits is not applicable. My use of the terms “generally distributed,” 
“occasional,” or “sporadic” follow the definitions of Smith (1965). 
Distribution is sometimes expressed in terms of sections of the state, 
such as eastern two-thirds or western half. In many instances, it is ex- 
pressed in terms of specific drainage systems or waters such as Mis- 
sissippi River, lower Ohio River, and Big Sandy River drainage. For 
species known in Kentucky from only one or a few records, the name of 
the stream or major drainage basin and the county involved usually are 
given, as well as the acronym of the museum or university that contains 
specimens. The counties of Kentucky are depicted in Figure 2. In a few 
cases I cited recent references to uncommon species, especially if the 
papers pointed out more detailed information on their Kentucky ranges. 
A list of a few problematical species is included in this report. The 
annotations for these species, all hypothetical in the Kentucky fauna, are 
self-explanatory. Also included in the problematical list are species that 
were included in earlier lists of Kentucky fishes, but with the present state 
of our knowledge can now be deleted from the Kentucky list. 
ANNOTATED LIST OF SPECIES 
The 229 species in the following list represent 69 genera and 27 
families. Twelve species (Alosa alabamae, Clinostomus elongatus, 
Hemitremia flammea, Hybopsis x-punctata, Notropis amnis, Lagochila 
lacera, Lota lota, Ammocrypta asprella, A. clara, A. vivax, Etheostoma 
microperca, Percina burtoni) have not been recently encountered and 
their current status in Kentucky is discussed.
