Helicarion mastersi is a species of air-breathing land snail, also referred to as a semi-slug because of its small shell. It is a terrestrial pulmonate gastropod mollusc in the family Helicarionidae.

The specific name mastersi is in honor of the Australian malacologist George Masters (1837-1912),[2] who collected the type specimen.[1]


Subspecies include:

  • Helicarion mastersi callidus Iredale, 1941[3][4]
