For those who think that all taxonomists do all day is debate Genus
placement of half the species in cetain families,  "it ain't
nessessarily so"!!  The generic and sub-generic levels of taxonomy are
possibly the most "artificial" of  the lot, and certainly the most
"unstable"!  The subfamily Trophoninae and the Polinices/Lunatia crowd
are two of the most problematic, for some reason (any theories??).  The
most stable taxonomic level is probably that of Family- few species are
kicked out of molluscan families into another one, but genera often play
musical chairs till the cows are at home and long asleep!
         The level of "Superfamily" is of major usefulness with mollusca also,
although i do not know why, in  technical  terms- could someone perhaps
shine some light on this subject?
