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
