We present spectroscopic observations of 33 emission line stars from the Sanduleak & Stephenson's (1973) list. This work is part of a program to investigate emission-line objects in the southern hemisphere whose nature is not well established in the literature. The objects were observed at two different spectral regions providing full coverage in the 3100–8700 Å interval. In this paper we describe the main spectroscopic features and discuss the nature of the objects. It is proposed that 16 of them are Be stars, 5 are peculiar Be stars, 4 are T Tauri stars, 7 are M-type stars with emission-lines and 1 is a Herbig object.
Key words: stars: emission-line, Be / stars: general / stars: pre-main sequence / stars: late-type
