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.[1]

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:

Synonyms
  • Thylacodes angulatus (Rousseau in Chenu, 1844) = Eualetes tulipa (Rousseau in Chenu, 1843)
  • Thylacodes caperatus (Tate & May, 1900) = Petaloconchus caperatus (Tate & May, 1900)
  • Thylacodes dentiferus (Mörch, 1859) = Thylacodes longifilis (Mörch, 1862)
  • Thylacodes effusus (Valenciennes in Chenu, 1844) = Eualetes tulipa (Rousseau in Chenu, 1843)
  • Thylacodes oryzata (Mörch, 1862) = Thylacodes oryzatus (Mörch, 1862)
