Fenimorea moseri is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.

The transverse sculpture consists of about eleven strong wave-like ribs with wider interspaces, the crests rounded.

These extend from the suture to the base, and are narrowed and curved like the top of an interrogation point when they pass over the fasciole.

[3] This species occurs in the demersal zone of the Gulf of Mexico; in the Atlantic Ocean off the Bahamas, North Carolina, the Florida Keys and Brazil.

This species was also found as a fossil in the strata of the Caloosahatchee Formation, Quaternary of Florida at North St Petersburg.
