In a search for obscured active galactic nuclei, 144 X-ray/IR emitting galaxies were selected. Optical spectroscopy of this sample is presented. A classification according to the nuclear activity shows that 28 are AGN, 39 are transition-type objects, and 44 are H II region-like galaxies. Three of the 28 AGN are Seyfert 1 galaxies and the others are of Type 2. It is suggested that the objects identified as narrow line AGN are obscured Seyfert 1. Most of the observed galaxies are seen edge-on, indicating that dust may have a flattened distribution coplanar to the disk of the parent galaxy. With the inclusion of the newly identified AGN, the sample of the X-ray emitting Seyfert 2 galaxies is fairly complete above a flux limit of log F(Hx) = -10.8.
