Peraclidae is a family of pelagic sea snails or "sea butterflies", marine gastropod molluscs in the superfamily Cymbulioidea.

This family has no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

This family was originally called Procymbuliidae Tesch, 1913 and then called Peraclididae by Wenz in 1938. The name Peraclidae takes precedence.

Peracle is the type genus of the family Peraclidae.

"Peraclis" Pelseener, 1888 is a unjustied modification (Giovine, F. 1988)

Description

The left-coiled shell resembles the shell of most snails. The columella is somewhat elongated into a curved rostrum. There is an operculum and a gill.
