Is it not less confusing to standardize on PA1-6/7?
I believe there are problems with the def of BA1 (PA3) below:
* It says "first pharyngeal/branchial" - to be internally consistent it should say "first branchial/3rd pharyngeal"
Does the mandibular and maxillary process really derive from this arch (and VP3) in frogs? Maybe this is a cut and paste error arising from confusion over the numbering system?

XAO uses the number system BA1=PA3
