A study of pulse profile variations from the Be/x--ray transient EXO 2030+375 is presented. This transient exhibited luminosity--dependent variations in its pulse profile during initial observations by EXOSAT in 1985 (Parmar et al. 1989, ApJ, 338, 359; Parmar, White, and Stella, 1989, ApJ, 338, 373). The Large Area Detectors (LADs) of the Burst and Transient Source Experiment (BATSE) on board the Compton Gamma--Ray Observatory (CGRO) have been used to view EXO 2030+375 on sixteen occasions. The study presented here is based on these BATSE observations.
