A Finding List of Stars of Spectral Type A7 and Earlier in Regions at High Galactic Latitudes. III. 4 HLF 4 An objective prism survey has been made of stars of spectral type A7 andearlier in a 45 square degree region in the 4 HLF 4 area (l^II =180°, b^II = -45°) as part of an investigation of galacticstructure perpendicular to the galactic plane. The survey reported herewas made with the 4° prism on the Michigan Curtis Schmidt telescopeat Cerro Tololo. A finding list containing positions and spectral typesfor 88 stars is presented with finding charts for the stars too faint tobe included in the Bonner Durchmusterung.
