Sorry about the bad picture - all I have at the moment.Â
I think this must be a turrid with the prominent anal notch, but I can find it...  It's about 47mm, and pretty definitely from the Philippines. Â
Any help appreciated - please excuse me if it's a dumb question...Â

Thanks - The second one from conchology.be looks like the one.  I checked gastropods.com (my favorite) thoroughly but couldn't find it, so I guess I'm at least glad it wasn't something obvious...
