The observations were made using mainly the Kiso Schmidt telescope, and partly using the CTIO Curtis Schmidt telescope. Our surveys extends the limiting magnitude to V=17.5 over an area of 150 square degrees, and the total number of detected H-alpha emission stars were 1157. The celestial coordinates and the V magnitudes were measured along with an eye estimation of the H-alpha intensities. The identification from the previous observations were also made. The brightness distribution, which is peaked around V=15, suggests that they are probable candidates of T Tauri-type stars.
