Anostoma carinatum is a species of terrestrial gastropod in the family Tomogeridae.
Description
Original description (translated from Latin): The shell is deeply chinked, conoid-lenticular (shaped like a cone and a lens), and somewhat solid, with a sharp keel. It is pale, with a narrow chestnut band above the keel and at the suture. The spire is a short cone. There are 5 rather flat whorls, the upper ones slightly striated. The body whorl is irregularly and wavy-ribbed and striated, with a convex base marked with chestnut spots, and is pitted anteriorly. The aperture continues the periphery of the spire and is semicircular, constricted by 6 strong, wavy lamellae. The peristome is white, widely expanded, and reflected, with a large, oblong hole on the right margin at the insertion point.
The length of the shell attains 13 mm, its maximum diameter 24.5 mm.
Distribution This species occurs in Brazil. (with English abstract)
