Yeah, that seems to have been lost at some point. From memory they used a picture of what Americans might call a soft dinner roll.
To me it would be more a roll than a bap or a barm, but they're almost synonyms. The weird one for me was when a mate insisted it was a teacake, and I suggested that would only apply if it had raisins in it. What I was describing, he insisted, was a fruit teacake, and without fruit it became a teacake. This is contrary to what the rest of the country believes outside of North Manchester, but has become a running joke for many years between us.
My wife was from Orkney and we spent a few months in the US. So we had US biscuits which are not the same as UK biscuits, US cookies which are not Orcadian cookies, West Country English buns which are definitely not US buns.
Your (Yorkshire?) teacakes are almost but not exactly like my buns.
You can imagine the confusion when the children asked for a cookie, a bun, or a biscuit while in the US.
When I asked for a bag of scraps in the chippy tonight the lady asked if I wanted "any breadcakes luv" showing me they were an 'outsider' (from about 30 miles away I reckon).
Also, no-one has called me 'duck' in the last week; which just feels wrong.
no bread is pictured
