Pachnodus velutinus
Species of gastropod
Pachnodus velutinus was a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Cerastidae. This species was endemic to the Seychelles. It is now extinct.
Hybridisation with Pachnodus niger caused the extinction.[1] Hybrids Pachnodus niger × velutinus still exist.
