ed,

Convex is the opposite of concave.

I have illustrated swamped ribs, right here, for decades for you. Maybe it would be easier if you just remembered a swamped rib has a ramp going down, at the breech, and a ramp going up at the muzzles. You should not make claims as to what rib a gun has if you are unsure of that.
