Identification of shells found in Caloosahatchee River

[dhcox57]

I greatly appreciate the id help. Indeed, I should have said, meant to say, something like "found in Southern Florida, Fort Myers area, in the Caloosahatchee river several miles upstream from the Gulf." An uncharacteristic lapse, I have been seeking id help on the net for years (mostly for flowers) and know the proper protocol. I felt that Marlo's comment was a mild reprimand, well-deserved, and will insure that in the future I include the basic location info (and more organized, better-sized photos). I am not a sheller myself, my dad has been combing Captiva Island (off the gulf coast of Florida) for years and can identify most of the shells he finds but he was not sure about the Pomacea and Planorbella. On an unrelated note, to see my other photos of my Florida trip, see: <a href="http://www.cig.usa.canon.com/p?p=EnLvffPhMDG" target="_blank"><!-- w --><a class="postlink" href="http://www.cig.usa.canon.com/p?p=EnLvffPhMDG">www.cig.usa.canon.com/p?p=EnLvffPhMDG</a><!-- w --></a>

Thanks again for the help and the pointer to the jaxshells site!
