The results of an objective prism survey for H-alpha emission-line stars in the 5 deg x 5 deg region around NGC 1333 are presented. 25 stars are identified as having the H-alpha line in emission, 11 of which had been discovered in the Lick H-alpha survey. The limiting magnitude of the present survey is about 16.7 mag. in blue. These are suspected to be mainly T Tauri stars. Based on multiexposure plates, it is found that the domain of H-alpha emission line stars is fairly well delineated and separated from other stars. Some interesting features in their space distribution are also discussed briefly, which reflect the dynamic effects and environmental conditions of star formation.
