Famelica monoceros is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.

The thin, ivory-white, high, narrow shell is drawn out, with fine spiral threads, a very oblique impressed suture, rounded whorls, and a contracted base produced into a longish snout.

Spirals—with the exception of the sinus-area, the whole surface is covered by fine, rounded, unequal, and irregularly interrupted spiral threads with rather broader intervals.

The body whorl is rounded, with a conical, protracted, but very lop-sided base running out into a longish straight columella and triangular snout.

The aperture is pear-shaped, scarcely pointed above, and protracted into a gradually narrowing siphonal canal below.
