Casual observer here, but here's the numbers previously listed

"BCI:Taxonomic data: Daudin 1803; fewer than 253 ventral scales; mid-body scale count 55-79 (Colombians have been found to have 80-84); 21 or more dorsal blotches (to vent)

BCS:Taxonomic data: Barbour 1906; scale count 65-67 dorsal rows; 214-247 ventrals; 49-70 subcaudals."

BCI-states FEWER than 253 ventrals-BCS 214-247... that is FEWER than 253
BCI-states scale count 55-79-BCS 65-67 again, that falls within this range
Would need the dorsal blotches and subcaudal counts to compare the other 2 stated ranges, but as a casual observer, these counts wouldn't differentiate the two. Simply because the BCI range is wide enough that from what I see, the BCS falls within those ranges. I'd also like to know how many animals were used to average out these numbers if I were to get seriously involved. If you have a sample size of 100 animals of one group and 10 from the other, it's hardly a definite range from which to make a definite ID. Basically, I mean the scale count range could increase if more animals had been counted from the BCS group since 65-67 is a pretty small window. Toss out some more details, I'm enjoying reading this stuff, though I have no intentions of getting into this "market" at all.
