>Dear Oliver,

I believe I see there a spiral sculpture of single stronger chords
alternating with few finer ones (say 3 to 5 or six finer every
stronger one) May be I don't see well. If I'm right the species is
one of the Mangelia unifasciata group, probably a pool of species. If
the sculpture is made of finer equal chords only, your determination
is correct.
All the best
enzo
