Dear Wes;-
    A wonderful approach to juvenile shells, a topic most of us wouldn't
approach with a ten foot microscope.
    Among the Epitoniidae, of course, the difference between most Juvies
and adults is---the adult is bigger. They just keep winding around
repeating the same pattern. Among Juvies, it is often impossible to tell
one species from another until they have completed a few whorls. In that
case, the best one can do is specify the genera or sub-genera.
