This is a very home-made-looking cheesy biscuit. Round cheesy biscuits with a slightly mounded shape, just as you would get if you cooked them yourself. M&S seems to like Cornish Cruncher cheddar which is, I suppose, why they chose it for these little biscuits.
And they are really tasty, very cheesy and with a nice soft crunch (such as a home-made biscuit would have). Pretty fabulous in fact.
