The fifth list of the Calan-Tololo Survey is presented. It contains information for 200 new southern quasars. Most objects have a B magnitude in the range 17 ≤ B < 19; 14 objects are brighter than 17th and 24 fainter than 19th. The redshift z of most quasars satisfies the inequality: 1.8 ≤ z ≤ 3.4; only 36 quasars have redshifts lower than 1.8. The typical quasar has B ≡ 18.3 and z ≡ 2.1. These quasars were found at Cerro Calan, searching objective prism plates taken at Cerro Tololo using the Curtis-Schmidt telescope, the thin UV prism and Eastman Kodak IIIa-J plates. The authors present identification charts, equatorial coordinates, an estimated blue magnitude and a preliminary redshift for every object. All quasars in this list have been confirmed using slit spectroscopy at the CTIO 4-m telescope or at the Las Campanas Observatory 2.5-m du Pont telescope. The spectroscopic data shall be presented elsewhere (Maza and Ruiz 1993).
