can you id this shell,is there a name for this?

I believe this is in Turridae (which is already 2 strikes against finding a name for it) :-)  I read about someone who found more than 150 species of Turridae in a cup of beach drift, and about half of them were probably unnamed.  Anyway, this looks close to some species of Eucyclostoma.  What is the size of this shell?  Do the lines on the ruler indicate millimeters?  If so, it's in the right size range for that genus.
