This looks a lot like Zachrysia provisoria (Pfeiffer, 1858), a Cuban
snail that was introduced into Florida, and has gradually spread to
other areas. I recently saw it on a list of introduced pests found in
Arizona. Could it have reached Kentucky? But, I'm no land snail
specialist. Maybe there is a local species in your area that looks
similar. I await the opinion of the terrestrial experts.
