The Banbury Springs lanx, or Banbury Springs limpet, is a rare species of freshwater snail, an aquatic gastropod mollusk in the family Lymnaeidae. First discovered in 1988, the species has not yet been officially described, and therefore it does not yet have a formal scientific name.
This freshwater limpet is endemic to the US State of Idaho, where it is known from a 10-kilometer stretch of the Snake River. In 1992 it was federally listed as an endangered species of the United States.[1]
It is found in four complexes of springs along the Snake River in south-central Idaho: Thousand Springs, Box Canyon Springs, Banbury Springs, and Briggs Springs.[2]
This snail is cinnamon red in color. The shell is conical in shape. It is up to 7.1 millimeters long by 6 wide and up to 4.3 millimeters tall.
This snail is similar in its morphology to species in the genus Lanx, but genetic analysis reveals that it is genetically more similar to the genus Fisherola.[2]
