A biscuit is similar to a cookie but we have loads of different ones plain ones sweet ones like shortbread some have cream in them like aeros I think that is what you call them? but they are alway crisp. One of the most popular are choclate digestive which is a wheat crisp biscuit with milk or plain choclate on top. Thre are literally abut 30 or forty different flavours type makes.
Biscuits in England are normally served with a cup of tea in some resturants you get coffee with a little sacket of crisp biscuit in it you probabably get that in the states as well as I have seen this in Europe as well with coffee.

That sounds somewhat like our (imported recipe, produced here) biscotti that is sold in coffee shops and grocery stores.
It sounds like your biscuits are in a category we don't have a specie name for, but, rather, individual product names, such as creme-filed wafer cookies we have (waffled) that I used to love when I still ate products with sugar. I can't remember their names any more but they are very common.
You're right about our biscuits being like your scones. Our biscuits are usually lighter, fluffier and less dense than what I remember of scones. Yummm for both.
