Fenimorea janetae, common name Janet's turrid, is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.
The interior of the aperture is bluish white with the dark band shining partly through this, and the callus on the columellar area is porcelaneous.
These have their strongest development anterior to the sinus at the summit and become attenuated posteriorly in crossing the base, where they extend to the basal fasciole.
Anterior to the depressed area the threads are replaced by pitted impressed lines, which also cover the base.
[2] This species occurs in the benthic zone of the Caribbean Sea, the Gulf of Mexico and Puerto Rico; in the Atlantic Ocean between Florida and Brazil.
