Splendrillia woodsi is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.

[2] The thick and strong shell is elongately turreted, with a spire about 2½ times the length of the aperture, and consisting of a smooth convex translucent protoconch of about 1½ whorls, succeeded by about seven, gradually increasing nodose whorls.

The whorls are very slightly convex, with a well-marked suture, and a broad flat or very slightly convex area below the suture occupying a little less than half the breadth of the whorls.

The aperture is narrow-ovate, with a broad shallow sinus fully occupying the flat area below the suture.

The breadth of the sinus is somewhat detracted from by the presence of a large and prominent tubercle on the columellar side.
