The shell on the right in the first picture doesn't look like Olividae.  It looks like Mitridae.  I think it may be a beachworn Mitra tristis.  The second picture appears to be Imbricaria conularis, Mitridae.  It is not native to the Sea of Cortez.  <span class="petit">--Last edited by Paul Monfils on 2010-04-24 04:35:26 --</span>

Thank you Paul Again!

Could you confirm the id, mitra Tristis, I send you a photo of a young specimen, because is to small, I saw on a web page that is from 1.5 cm.

Thank you!

Sorry about the imbricaria I was made a mistake about the photo and the place.
