Sowerby III, 1919 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] The thin shell is globosely pyriform, with a perforate axis.

The aperture is oblong, produced anteriorly into a wide subrecurved siphonal canal.

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The foot is small, short, obtuse and rounded behind, with a thin, expanded, disk-like lobe in front, and the siphon is obsolete.
