Sorry for posting that personal message to Mark - the finger is quicker
than the eye!

I have been wondering about all those 50 "valid" named varieties of
Liguus fasciatus (Muller): do they breed true?  Also, do some of them
have very limited ranges, and on any given hummock in the Everglades,
how many varieties is one likely to find?

Much better today! (almost 8 C ..)
