Naesiotus jervisensis (Dall)

Jervis Island Snail (Naesiotus jervisensis)

The Jervis Island Snail was described in 1917, it was apparently already extinct at that time, since only dead shells were found.:

A few dead specimens were collected on Jervis Island [Isla Rábida] at an elevation of 900 to 1000 feet.
One or two of these were fresh enough to admit of the hope that living specimens may be secured by some future collector.
