:I just looked at Klauber, who gives quite different scale counts for males and females, and with overlap between sexes (see post on venomous forum) - do your counts apply to a particular population, or are they a summary of variation in the species as a whole? Just curious.
The counts I gave are from the work I was involved with, with Nebraskas C.horridus. so far they've also held good for other near-by populations of C.horridus and even the Iowa population of C.viridis. Due to the overlap you mention, we still probe for any mid count snakes. We have so far had only one snake that had a count that led to a wrong guess about sex and that's with a C.horridus that doesn't probe right either (a wildlife rescue animal that probes female, counts is 24 but combats every C.horridus male I put in with him......go figure)
