''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''.〔Bieler, R.; Rosenberg, G. (2015). Thylacodes Guettard, 1770. In: MolluscaBase (2015). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=598651 on 2015-07-17〕 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. ==Species== Species within the genus ''Thylacodes'' include: * ''Thylacodes adamsii'' (Mörch, 1859) * ''Thylacodes aotearoicus'' (J.
