On any application to bring land under this Act by a description different from that in the muniments of title, the Registrar may grant the application as to the land in the occupation of the applicant if the discrepancy between the land as occupied and as described in the muniments appears to be due to the inaccuracy of any survey or plan or description on the sale of the land by the Government of Uganda or controlling authority or on any subsequent dealing therewith, or to any discrepancy between the actual measurements or bearings at any time made or marked on the ground and those represented or mentioned in any plan or description.
