Mirus stalix is a species of air-breathing land snails, a terrestrial pulmonate gastropod in the subfamily Eninae of the family Enidae.

They were first described in 1863 by British malacologist William Henry Benson.

Description

The length of the shell attains 20 mm (0.79 in), its diameter 7 mm (0.28 in).

(Original description in Latin) The shell is narrowly perforate, oblong-conic, somewhat solid, with obliquely irregularly folded striations and a very densely spirally striated epidermis. It is chestnut-coloured, marked with oblique streaks, while the suture, base, and apex are whitish.

The spire is elongate-conic, with a somewhat blunt apex and a slightly impressed suture, sometimes margined. There are seven slightly convex whorls, the body whorl slightly compressed at the base and barely ascending anteriorly.

The aperture is somewhat oblique, narrowly pear-shaped, chestnut-coloured inside, with a slightly expanded, faintly reflexed, whitish peristome. The margins are distant and not converging, with the columellar margin broad and joined above by an oblique chestnut-coloured callus.
