The star MWC 84 (CI Cam) was first discovered to be an emission line object classified Bep (Merrill & Burwell, 1933), then classified as a symbiotic star and finally identified as the possible optical counterpart of the X-ray transient XTE J0421+560

We present and discuss the observations of 14 Ae and A type shell stars in the visual, the Hα region and the near infrared. At least 57% of these stars are spectrum variables. The Paschen lines are formed in a region which has the characterics of gi
