looks to me like at least one defintely sinistral (near top right) of the first image.

Hello Allen,

I personally collected Columbella rustica at several places in the Mediterranean (it's locally very common over here) and I can assure you that all the thousands of the specimens I collected (or have scanned in the strandline) were 100% right-handed.

I suspect another mirror-image photo is the cause of the depiction in the article.

mvg, Erick Staal

Note that the Columbella rustica beads pictured are 50% sinistral.  Is this common Mediterranean species often found with sinistral specimens, or was the collector choosing the odd shells because they are rare and therefore more valuable?
