† Turris conspicua May, 1922 Zemacies conspicua is an extinct species of sea snail, a marine gastropod mollusk in the family Borsoniidae.

(Original description) The very large shell is fusiform.

The sculpture indicates a fairly deep sinus immediately below the suture.

The upper whorls are faintly coronate at the angle, and ridged by lines of growth and are concentrically finely lirate all over.
