According to a news item in American Paleontologist (v. 7, no. 1, p. 14; Feb. 1999), Frank Wesselingh and Edmund Gittenberger recently discovered a Miocene land snail from the Amazon region of Colombia. They reported specimens up to 25.6 cm long (about 10 inches). Unfortunately, they were not able to collect complete specimens. The full report is in Veliger (v. 42, p. 67; 1999), a journal that, unlike Doug Shelton's Malacological Expositor, does exist, although not in any of the local libraries. That's a pretty big snail, and I have to wonder how large its radula was. Here's a question for the gastropodologists: Is there any relationship between the size of a snail's shell and the size of its radula? Andrew K.
