Hi John,

Thanks for your feedback. I tried to have a look at the shells at the 
top-right of the first photo, but these all seem right-handed to me. 
Perhaps I'm looking at the wrong shell(s)?

By the way. The second photo definitely has mirror-images: please have a 
look at the Columbella specimens f, g, h, i and j. Assuming that these 
all depict the same shell once from the back and once from the front per 
shell, the shells on the back are depicted right-handed (I rotated the 
shells in my head. :-) ), but the photo's with the apertures towards the 
viewer are depicted left-handed. This cannot both be true (if e.g. the 
shell(s) depicted under f represent the same shell).

As I dared to state before: I've seen many specimens of Columbella 
rustica and I wish there would have been a sinistral one in my sights, 
but alas.

Sincerely, Erick
