Round notice (8)
I believe the answer is:
circular
I believe this is a double definition.
'round' is the first definition.
('circular' can be a synonym of 'round')
'notice' is the second definition.
(thesaurus)
(Other definitions for circular that I've seen before include "Letter or notice copied to a number of people" , "plug, perhaps" , "Leaflet for mass distribution" , "Shaped like a ring" , "that's passed through a rectangular slot?" .)
