Gibbus lyonetianus (Pallas)

Purple Gibbus Snail (Gibbus lyonetianus

This species was described in 1780.  

The Purple Gibbus Snail was endemic to the island of Mauritius, it had a conspicuous, strangely compressed shell and probably was a predatory species.  


It appears to have been a quite colorful species.:  

The sole of the foot in this species is yellow; the anterior part of the upper surface varies from reddish claret to purple, and the posterior is yellow, dotted with minute purplish spots; the tentacles are dull purple.” [1]
