An objective-prism survey of the Small Magellanic Cloud has been made on IIIaJ plates taken with the 1 m ESO Schmidt telescope and has resulted in the detection of nearly 200 late K and M supergiant stars. Most of these are new probable members of the SMC which do not appear in previous catalogues. The mean visual absolute magnitude of -6.0 agrees with the visual absolute magnitude of lab-lb galactic supergiants of spectral types M0 to M4. The fraction of known variable stars found in this catalogue is barely 10 percent; this is 2.5 times less than the value found for the corresponding stars in the LMC. The catalogue provides accurate 1975 coordinates, finding charts, spectral types, V magnitudes, indications concerning radial velocities when available and designations of the stars in other catalogues.
