There are three other types of local authorities: municipal councils (18), urban councils (13) and pradeshiya sabha, also called pradesha sabhai (256). Local authorities were originally based on feudal counties named ''korale'' and ''rata'', and were formerly known as "D.R.O. divisions" after the divisional revenue officer. Later the D.R.O.s became "assistant government agents," and the divisions were known as "A.G.A. divisions". These divisional secretariats are currently administered by a divisional secretary.
