Auriculastra duplicata is a species of air-breathing land snail, a terrestrial gastropod mollusc in the family Ellobiidae, the salt marsh snails.
Description (Original description in Latin) The shell is imperforate, oblong, and solid, and is arcuately striated; beneath the deciduous epidermis it is greenish-tawny to white. The spire is short, conical, and somewhat blunt; the suture is obsolete (indistinct). The 5 - 6 whorls are contiguous; the body whorl forms the greater part of the length, is inflated above the middle, and is slightly attenuated at the base. The aperture is vertical and semi-elliptical, and is canaliculated at the base. The apertural wall is furnished with a nodiform callus and, below it, with a transverse, lamella-like fold. The columella shows two oblique, parallel folds. The peristome is simple, with the right margin slightly arched and somewhat callous within.Pfeiffer, L. (1854-1860). Novitates Conchologicae.
