Vorticifex solida (Dall)

Solid Ramshorn (Vorticifex solida)

The Solid Ramshorn was apparently described based on fossil- or subfossil shells, however, it appears to have survived until recently at least at one site: Lake Tahoe which is situated on the state line between California and Nevada, USA.

The status of the taxon appears to be completely unknown, it might be extinct or it might still be alive; it might furthermore be identical with another species, the Artemesian Ramshorn (Vorticifex effusa (I. Lea)) anyway.
