Thanks, Robert, for telling me about the picture in Florida's Fabulous
Seashells.  The shape in the book sure looks like what I found but the color
of the ones I found yesterday were chocolate brown and the animal of the one
live-taken was dark, not cream-colored.  The apertures are almost the color
of the Knobbed Whelk on the next page.

The one I have from the 80's is pure orange over the entire shell except for
the white stripe.

Why is it that I can't find any reference to this species in any of my books?
 The only place I found the name was in Rice's price book.

Thanks for the info everyone!
