The constituency consisted of the historic county of Devon, excluding the city of Exeter which had the status of a county in itself after 1537. (Although Devon contained a number of other parliamentary boroughs, each of which elected two MPs in its own right for part of the period when Devon was a constituency, these were not excluded from the county constituency, and owning property within the borough could confer a vote at the county election. This was not the case, though, for Exeter.)
