Peraclidae is a family of pelagic sea snails or "sea butterflies", marine gastropod molluscs in the superfamily Cymbulioidea. ^[2]

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. ^[2] 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.
