Leptoconchus is a genus of medium-sized sea snails, marine gastropod mollusks in the family Muricidae, subfamily Coralliophilinae, the coral snails or coral shells. ^[1]

Description

The thin shell is globosely pyriform, with a perforate axis. The umbilicus is partly concealed by the reflected inner lip. The spire is obtuse. The aperture is oblong, produced anteriorly into a wide subrecurved siphonal canal.

The mantle-margin is greatly thickened and fleshy. The tentacles are small, broad, and united at their bases. The eyes are small and black, on the outer side of the tentacles, near their tips. The foot is small, short, obtuse and rounded behind, with a thin, expanded, disk-like lobe in front, and the siphon is obsolete.

There is no operculum. ^[2]
