Inodrillia pharcida is a species of sea snail, a marine gastropod mollusc in the family Horaiclavidae.
(Original description) The slender, thin shell is yellowish-white, with a dull surface, except for the glassy and translucent protoconch.
The protoconch is thin, inflated, the (nuclear) first two whorls) polished, smooth, and free from sculpture, passing abruptly into the dull and lustreless surface of the adult shell.
For the remainder, the transverse sculpture consists of subequal rils, largest on the periphery, smaller toward the sutures, which they reach above and below, the track of the notch not being marked by a flattened band, as is generally the case.
The completion of the adult aperture is marked by a particularly large rib or swelling of the margin, which becomes more conspicuous in case the shell continues to grow.
