Quoting John and Nhung <nhungjohn@eastlink.ca>:
> I have never had a problem separating red-bellies from ringnecks.
> Redbellies have the three yellow spots around the neck in various sorts of
> fusions, and have a series of longitudinal stripes dorsally. Ringnecks have
> a pale yellow ring around the neck and a solid bluish gray colour dorsally.
> Yup, then there's the scale contrast (keeled versus smooth).
* but Redbellies can be a great variety of colours, from black to
copper red, so for the ones that are charcoal grey, you need to see
the spots-rather-than-ring, keeled scales, and reddish-pink rather
than orange underbelly.
> Difficult snakes to confuse, if you've seen both.
* but if you've only seen one, and that briefly, confusion is possible.

"[The] two fundamental steps of scientific thought - the conjecture
and refutation of Popper - have little place in the usual conception
of intelligence. If something is to be dismissed as inadequate, it is
surely not Darwin [, whose] works manifest the activity of a mind
seeking for wisdom, a value which conventional philosophy has largely
abandoned." Ghiselen, 1969. Triumph of the Darwinian Method, p 237.
