Low-resolution objective-prism spectra (1360{AA}/mm at H{gamma}) of 184 late-type stars in the Galactic antirotation direction have been obtained with the Curtis Schmidt telescope at Cerro Tololo Inter-American Observatory. The stars have been classified into three groups: F6-G2, G3-K0, and K1-M8. Subsequent observations on the BV and DDO systems have been obtained. The correlation between the thin-prism classes and the DDO classes is as expected, with no significant systematic differences of note. A comparison of Guide Star Catalog magnitudes, corrected to V, is also made, with favorable results. The stars in this list are expected to be useful for studying the structure and star formation history of the Milky Way.
