>Does anyone know of any sinistral Buccinum undatum occurring in North America, or are most from the North Sea?
>Anyone heard of a sinistral specimen of any OTHER species of Buccinum?

I have a shower curtain that depicts a sinistral buccinid; however, as it also depicts a "Strombus" gigas with dextral body and sinistral aperture, I do not think it is too reliable a source of evidence.  It's also obvious that there was a mix-up between the folks who got the names and pictures out of a shell book and the ones assembling them into the curtain pattern.
