Auriculastra gassiesi

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]

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