Attention all Columbellidae Experts!
I have about 30 tiny Anachis shells, and I am pretty sure they are either
A. avara or A. lafresnayi. However, I can't tell the two species apart! The
pictures in the books I am using are to small to help very much, and the
descriptions they provide are very vague. Are there any "secrets" to tell
them apart?
Many Thanks in advance,
Patrick
