I was wanting to know if there are any different ID markings between <i>H. major</i>, <i>H. davidis</i> and <i>H. articularis</i>. I have looked through countless field guides & without written descrïptions, I can't distinguish between them. Only the listed names give away the species.
What should I look for in case I receive an unknown <i>Harpa</i> that looks most like either of these three species? <img src="images/smiley/confused.gif" alt="" border="0" />
This page maybe helps:

Are those the columellar side of <i>Harpas</i> in the diagrams?
Yes, !
Okay thanks! I think this will help a lot! Can I save this pic for future reference?
Just last week there was a discussion on this topic on Conch-L.  If you would like to review this discussion, which includes an offer of a recent article by the author, go to <a href="" target="_blank"><!-- m --><a class="postlink" href=""></a><!-- m --></a>  and select July 2010, week 2. There you will find several references to the topic "Those Beautiful Harps", with a dozen or so total messages.  <span class="petit">--Last edited by Paul Monfils on 2010-07-17 03:13:59 --</span>
