Thanks everybody for answering.
Dave, if you are interesting to buy some specimens, you can find it on my website <a href="http://www.khanshells.com." target="_blank"><!-- w --><a class="postlink" href="http://www.khanshells.com">www.khanshells.com</a><!-- w -->.</a>
I am really not sure this can be a form of C. ochroglottis.
This is pictures of aperture from 2 specimens, maybe to confirm Conchylinet's remark.
