Hi all. Just found this gastropod in a box for my collection and realized that the tag with all the info is gone. Sad to say. I found this along the Vanduzen River about 20 miles from where it empty's into the Eel river. I cant even recall the Formation. I think its one of the Wildcat group Formations? I do remember that I dontated one to a fella who worked for the Natural History Museum of LA. Any help would be appreciated. Thank you
