Identify shells

[kalilikane]

Does anyone know what kind of shells these are? They are 4 to 5 inches in size. Thank you for your help.

A 4 to 5 inch species shouldn't be hard to identify.  I suspect the reason you have received no response is that others, like myself, cannot see any image here.

I still cannot see your images, but someone else who can see them was kind enough to forward them to me.  These are Cymbiola nobilis, the "noble volute", common in the area from Thailand to Singapore, where they are harvested as a source of food.  Also found less often from Taiwan to the Philippines.
