Snail

[wolfi]

Hi Pierre,
yes, it´s a terrestrial snail, obviously familiy Streptaxidae. Should be genus Gonaxis, subgenus Macrogonaxis. Might be Gonaxis quadrilateralis (Preston, 1910), a carnivor species introduced from Africa (Kenya) to several islands in the indo-pacific area in the attempt to control the population increase of Achatina fulica, just like Euglandina rosea. The results were disastrous, concerning the effects on the local malacofauna.
Kind regards: wolf
