Oreohelix carinifera, common name keeled mountainsnail, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Oreohelicidae.

Pilsbry's original text (the type description) reads as follows: OREOHELIX CARINIFERA, n. sp.

Subsequent whorls are strongly convex around the upper (inner) part, becoming concave near the outer edge; the striation is rougher, and some weak traces of spiral striae appear in places.

The last whorl is noticeably concave above and below the peripheral keel; it descends very slightly or not at all in front, and on the base there are very inconspicuous, well spaced spirals composed of granules.

A very similar small form was taken with O. haydeni in the Wasatch Mountains many years ago by the Wheeler Expedition, but I think it will prove to be distinct.
