and I would love to have the reference if you can find it and the time to look. It does propose an interesting question to the evolutionary biology of snakes, since it is assumed that the vestigial left lung (or lost thereof) is related to the body morphology of snakes (i.e. slim, cylindrical, legless build). I would suspect that it would be presumed that these four speies would all be not only related (and I don't recall that they are all that close) but as you said, primitive types, which would then suggest that members of the genus Crotalus were sister taxa to Agkistrodon or perhaps not close at all.
Thanks for the enlightenment,
Later, KW
