Thanks Gary,

Am I correct in assuming the upper photo - on black background - is taken through the glass so we are seeing a ventral [underside] view, while the lower photo is a view of the upper surface? I need to confirm this so we know if the ribbon is a clockwise or anticlockwise spiral.

Also has the ribbon been lifted off the glass in the lower photo? I would assume all the egg ribbon is stuck down but in this photo the outer whorl doesn't seem to be attached. Is this an optical illusion?

Best wishes,
Bill Rudman
