Odostomia umbilicaris is a species of sea snail, a marine gastropod mollusc in the family Pyramidellidae, the pyrams and their allies.

[2][3] The white shell is thin, transparent, and very glossy.

The five to six whorls of the teleoconch have deep sutures.

The columellar tooth is small, but prominent.

Owing to the transparency of the whorls, the periphery of each appears like a narrow band round the top of the succeeding one.
