Corinnaeturris leucomata is a species of sea snail, a marine gastropod mollusk in the family Clathurellidae.

The protoconch is thin, very minute, inflated, clear transparent brown and shows a shining surface.

On the body whorl (about six on the middle and nine on the anterior third) in advance of the peripheral nodules are about fifteen sharply raised threads, with interspaces up to 0.5 mm in width.

Other revolving sculpture consistis of microscopic striae covering the shell, which in favorable localities in crossing the lines of growth (as, for instance, on the notch-band) occasionally give rise to microscopic shagreening, invisible except in a good light and under a good lens.

[2] This species occurs in the Atlantic Ocean off the Cape Verdes and in the Gulf of Mexico.
