This shell seems unusual to me, anybody recognizes it?
I don't remember where I found the shell.

I posted the pictures at

Hi Dannie, it is the Clear Sundial Shell, <i>Architeconica perspectiva</i>(Linne. 1758) and comes from the Indo-Pacific region.

Thank you very much. I must have gotten it in Australia.
