Procymbuliidae, 1913


}}Peraclidae is a family of pelagic sea snails or "sea butterflies", marine gastropod mollusks 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.

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.

Peracle bispinosa is not synonyms of Peracle diversa. It is quite a different species!
