What are these dishes called???

[meandrick2]

My grandmother gave me some plates with teacups back in the early 1970's.  They are clear green and the plates have a rim in them that the teat cup sits in.  I am assuming that they were used in the parlour during teas/luncheons.  I am trying to research them but am not getting very far on the internet since I do not know what they were actually called.  Any help would be appreciated.

These are snack or sandwich trays. You would place your snack in the larger section and you have the small round area to hold your tea or coffee cup.
