They don't look like English biscuits to me. Entirely too fancy.
English biscuits are things like Digestives, Rich Tea, Bourbon, Custard Cream, Nice.
They are circular or oblong. They usually do not have inclusions (well, except Garibaldis, but I've never liked Garibaldis). They are almost always good for dunking in tea.
