`Yeah, well sometimes it's not a matter of can't be bothered...sometimes our brain cells fade as we get older and we just can't keep relearning things we learned 30 years ago..'
Ok, there are legitimate reasons, too.
`I am one of the ones that still uses Chondro and Lampropeltis getulus, and just recently started using Nerodia instead of Natrix.'
Personally, I'm going to keep on using Chondropython, but that's just because I think Kluge's full of it if he thinks they ought to be Morelia. 
`All kidding aside..it's tough to keep up with proposed changes, accepted changes, etc. unless you are a Taxonomist. The thing is, even if you use Elaphe guttata guttata 5 years from now, people wil still know precisely which species you are referring to. That is the purpose of scientific names anyway.'
I agree. But, then, Natrix sipedon would get you some blank stares.
`What bugs me is when you hear people trying to pronounce the names and butchering them. I have heard people pronounce "piscivorous" as "piss-ka-VOR-us", rossalleni as "rose-a-LEAN-ie", "goini" as "go-EYE-nee" or"go-EYE-nye", "getulus" as "JET-you-lus", "Crotalus" as "crow-TAIL-us", "conanti" as "ko-NAN-tee". '
OTOH, I find `mispronunciations' of systematic names pretty understandable--so far as I can tell there simply isn't a consistent and widely used system of pronunciation for Latin in a scientific context, so unless you happen to've heard the `correct' pronunciation (and had some way of knowing it was the correct pronunciation), it's just a matter of guessing. And with `Elaphe', I don't think I've ever seen a consensus on how you're supposed to pronounce that one. I've seen people argue in favor of `eh-LAFF', `eh-LAFF-ee', `eh-LAFE' and maybe another one or two I'm not thinking of. I've always thought the misspelling of `Spilotes' as `Spiloties', which I assume is based of the accepted pronunciation of the last `e' as a long vowel, was pretty amusing, though...
