No, it's an Indo-Pacific ovulid, one of the ones with an oval shell, a trace of an orange ring, and a few spots on the shell, although I can't tell how many through the semi-transparent mantle. All the Cyphoma species are somewhat cylindrical with a swollen area in the middle of the shell, and truncated ends. This one doesn't share those characteristics. I'll try to give you a closer ID when I get home from work.
Cheers,
Don
