摘要：
We present spectroscopic observations of 25 emission-line stars in the Canis Majoris region of Schwartz, Persson, & Hamann. This work is part of a program to investigate emission-line objects in the southern hemisphere. The objects were observed in three different spectral regions providing full coverage in the interval 3100-7500 Angstrom. In this paper, we describe some of the main spectroscopic features and . discuss the nature of the objects. It is proposed that 16 of them are Be stars and seven are T Tauri stars. Two objects failed to show emission lines.
