The GovernmentTown of Caltowie, slightly to the south of the hundred's centre, which was named for the hundred, was surveyed a few months after the hundred proclamation in November 1871. Adjacent localities of Caltowie West and Caltowie North were officially named as such, based on the long associated names, with reference to their position within the hundred. The only other bounded locality within the hundred is the western flank of Jamestown on the eastern side of the hundred.
