Odostomia (Odetta) felix Dall & Bartsch, 1906 (basionym) Menestho felix is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.

They are marked by strong, equally developed, spiral keels which are separated by subequal, deep, rounded sulci.

The penultimate whorl has four keels, the posterior one of which marks the summit and is a little wider than the rest and somewhat flattened.

These keels, as well as the sulci, gradually diminish in breadth from the periphery to the umbilical region.

The columella is rather heavy, somewhat curved, backed up by the attenuated base and provided with a strong oblique fold at its insertion.
