Drillia winchesterae Pilsbry, 1922 Carinodrillia winchesterae is an extinct species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.

(Original description) This species is very similar to Carinodrillia elocata, but it is more slender with a longer anterior canal and a deeper posterior sinus.

On the face of the body whorl there are 18 narrow, high spiral ridges, a smaller cord above the upper one and a strong, acute cord below the suture.

The anal sinus is deep, rounded posteriorly and contracted a little anteriorly.

[2] Fossils of this marine species were found in Tertiary strata of the Dominican Republic.
