Extinct genus of molluscs
Latouchella is an extinct genus of marine invertebrate animal, that is considered to be a mollusk and which may be a sea snail, a gastropod. It is a helcionellid from the Tommotian epoch of what is now Siberia. Its tightly coiled, spiral shell contains a number of low "walls" running up the front surface of the interior; these would have directed water currents within its shell. Between these walls are a series of furrows, parallel to the shell's aperture, giving casts of the internal structure the appearance of a railway line, with sleepers (created by furrows) tying together paired rails that run towards the apex of the shell.
It was named by Edgar Sterling Cobbold in 1921 for the Rev. William Martin Digues La Touche of Wistanstow, Shropshire, England, in whose collection it was found.
Description.
This genus had a curved, segmented shell, and it is often reconstructed as a snail-like creature.

Paleozoic molluscs of uncertain systematic position.
"Latouchella" was a type genus in the family Latouchellidae Golikov &amp; Starobogatov, 1989, however Latouchellidae is a synonym of Coreospiridae.
