Auriculastra gassiesi is a species of air-breathing land snail, a terrestrial gastropod mollusc in the family Ellobiidae, the salt marsh snails.[1]

Description

The length of the shell attains 5.5 mm, its diameter 2.5 mm.

(Original description in Latin) The shell is small, imperforate (lacking an opening at the base), and spindle-shaped; it is relatively solid, smooth, shiny, and yellow-brown in color with a single chestnut-colored band. The spire is mammillated with a fine, sharp point at the apex and is somewhat brownish. It consists of seven nearly flat whorls joined by a linear suture; the body whorl slightly exceeds the spire in height and is rounded at its base. The aperture is vertical and shaped like a narrow, pointed oval; inside, it is generally a chestnut-brown and features three folds. Two of these are parietal folds—the upper one is quite small and barely visible, while the other is horizontal and strong; the third is a smaller columellar fold, which in most specimens extends all the way to the margin. The peristome (the lip of the aperture) is blunt, thick, and blackish-chestnut, with the right margin being slightly wavy.[2]

Distribution

This species occurs at the coast of Madagascar and the Comores.
