Etrema mirabilis
Etrema mirabilis is an extinct species of sea snail, a marine gastropod mollusc, in the family Pseudomelatomidae. Fossils of the species date to late Miocene strata of the Gippsland Basin of Victoria, Australia.
Description
In the original description, Powell described the species as follows:
The holotype of the species measures in length and has a diameter of. It can be distinguished from E. gippslandensis due to the slight angulation on the last whorl of the shell.
Taxonomy
The species was first described by A. W. B. Powell in 1944 as Pseudoinquisitor trinervis. The holotype was collected by farmer Christopher Ritchie, likely from the Mississippi Creek near Lakes Entrance in Victoria, Australia at an unknown date prior to 1937. A part of the Finlay Collection held by the Auckland [War Memorial Museum], H. J. Finlay had stolen the specimen from the National Museum of Victoria's Dennant Collection, which had been on loan to F. A. Singleton.
Distribution
This extinct marine species occurs in late Miocene strata of the Gippsland Basin of Victoria, Australia, including the Jemmys Point Formation.
