Acrilla lamberti is an extinct species of sea snail, a marine gastropod mollusk in the family Epitoniidae, the wentletraps.

(Original description in French) The shell is turrilicate, narrow and very pointed at the top.

Its very long spire is made up of thirteen convex whorls on which seventeen simple, straight, fairly narrow longitudinal ribs rise.

The body whorl is short, its base occupied by a large disc whose edge reaches the circumference.

The oval aperture is small, with continuous edges, but having the anterior portion of the peristome in a straight line, ending in an angle obtuse at each end, a biangulate arrangement due to the shape of the disc.
