Banbury Springs limpet (Lanx sp.)

General Information
The Banbury Springs lanx (Lanx n sp.) (undescribed) was first discovered in 1988 by Terrence Frest. Its conical, pyramid-shaped shell is red-cinnamon in color, ranges from .09 to .28 inch long, and IS only .03 to .17- inch tall. Because specialized respiratory organs are lacking, this species is particularly sensitive to dissolved oxygen fluctuations. It requires cold, clear and well-oxygenated water with swift currents. Lanx are found on smooth basalt, boulders, or cobble-sized grounds ranging from 2 to 20 inches deep, but they avoid areas with green algae. Currently, this species only exists at four cold-spring locations that are isolated from each other: Thousand Springs, Box Canyon Springs, Briggs Springs and Banbury Springs. Primary factors affecting the lanx in its four remaining coldwater spring complexes and tributaries are effects of habitat modification, spring flow reduction, groundwater quality, the invasive New Zealand mudsnail and inadequate regulatory mechanisms. In 1992, the Service listed the species as Endangered under the Endangered Species Act. The threats indicated at the time of listing in 1992 still remain today, rendering the Banbury Springs lanx in danger of extinction in a significant portion of its range. The Service therefore recommended in its 5-year Review of the species that no change in the listing classification for the species, and that it remain as endangered under the Act.
