Well they aren't, as far as I've eaten them. My ex MIL made exactly the same batter. Maybe it's different because her roots were Scottish?
Anyway I guess we can only compare recipes to be sure?
I use a ratio of 500 ml of milk to 300 g of flour, and 2 medium eggs.
Ratio: 300ml milk, 100g plain flour, 2 large eggs. I think that is fairly standard having looked at a few BBC recipes. Your ratio has considerably more flour to liquid, hence the thicker result. Mine look more like crepes. Maybe it is a Scottish thing (although traditional 'Scotch pancakes' are much thicker). I'm sure they are delicious.
