John R. Holsinger and David C. Culver 
described from Burnet Cave in Barren County, Ky., and has since been 
identified from Bristol Caverns in east Tennessee by Hubricht (in litt.). 
Helicodiscus inermis, recorded from two caves in west-central Virginia, 
is also reported from caves in Alabama, Georgia, and Tennessee, and 
from surface localities elsewhere in the eastern and southern United 
States (see Hubricht 1964, 1985; Holsinger and Peck 1971). 
In the Polygyridae, Mesodon appressus is recorded from Flannery 
Cave in Scott County, and this species, in its broadest sense, is also 
reported from caves in Kentucky and Tennessee by Barr (1961, 1967a) 
and Hubricht (1964). Glyphyalinia specus (Zonitidae), a white, apparently 
blind species unknown outside caves and possibly a troglobite, is 
recorded from Bristol Caverns in Sullivan County and also from caves 
in Alabama, Georgia, Kentucky, middle Tennessee, and possibly West 
Virginia (see Hubricht 1965, 1985; Barr 1967a; Holsinger and Peck 
1971; Holsinger et al. 1976). Another zonitid, Zonitoides arboreus, 
probably a troglophile, is recorded from one cave in the study area and 
from many other caves in the east-central and southeastern United 
States (see Hubricht 1964, Holsinger and Peck 1971, Peck and Lewis 
1978).
