Description

Like all species in the family Clausiliidae, Cochlodina laminata has a clausilium or "door". The second image shows the shape of the clausilium in this species.

The shell is brown to cherry red, nearly smooth and shiny. The parietalis is small, the columellaris is more prominent, the palatal callus is weak, the subcolumellaris is visible in an oblique view. .[3]

The weight of the adult live snail is about 138±5 mg.[4]
