''Patera clarki nantahala'', the noonday globe, is a subspecies of ''Patera clarki'', a land snail in the family Polygyridae. It is endemic to North Carolina in the United States. The name ''nantahala'' is a Cherokee word which means noonday. This subspecies was given this name because the snail lives in a deep gorge where the sunshine does not reach the ground until the middle of the day.〔U.S. Fish and Wildlife Service. July 3 1978.
