Olividae from Western Indian Ocean

[conchylinet]

Hello again,
I cannot clearly identify tropical Olividae species.
What specie(s) could be that one ?
It is from Mauritius and sizes 24mm.

Thank you.

Never seen one like that before but judging by the size of the protoconch and thin-ness of the lip I would say it was a juvenile, probably ponderosa. It could even be some strange annulata form.
