Inquisitor spicata is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae.

Sculpture :—Except where interrupted by the spirals, the shell is overrun by very close microscopic radial lamellae, a series of which rise along the suture and curl into arched scales.

On the body whorl, anterior to the fasciole, run about sixteen rather flat-topped spiral lyrae, about twice their own breadth apart, between which one or two-minute interstitial threads may occur.

Behind the aperture is a varical swelling, followed by a narrow pocket groove, beyond which again the outer lip is turned inwards, giving rise to a short free edge.

The callus on the columella is a thick sheet, the anterior edge of which is free from the preceding whorl.
