Thylacodes is a genus of sea snails, marine gastropod mollusks in the family Vermetidae, the worm snails or worm shells. The species in this genus were previously placed in the genus Serpulorbis.[2]
Unlike some other vermetids, the species in this genus have no operculum.
Like other vermetids, the species in this genus do not have regular shell coiling like that of a typical gastropod shell, instead they have shells which are irregular. They are usually cemented onto a hard surface. Because of all this, the shells resemble the calcareous tubes of worms in the polychaete family Serpulidae.
