Well, for those that asked...
 
I'm a PhD student at the University of Alabama, and I'm working on doing
a phylogenetic revision of the freshwater snail genus Lithasia.  I did
my masters work under Ross Gundersen (same one on this list) working on
the marine snail Puperita.
 
So, if anyone can provide me with fresh Lithasia, lemme know!
 
I brought up Liguus because someone mentioned it earlier, same with the
species concept idea stuff.
