We report the discovery of a new radio galaxy within the location error boxof the gamma-ray source 3EG J1735-1500. The galaxy is a double-sided jet sourceforming a large angle with the line of sight. Optical observations reveal a V ~18 magnitude galaxy at the position of the radio core. Although the associationwith the EGRET source is not confirmed at the present stage, because there is acompeting, alternative gamma-ray candidate within the location error contourswhich is also studied here, the case deserves further attention. The new radiogalaxy can be used to test the recently proposed possibility of gamma-rayemitting radio galaxies beyond the already known case of Centaurus A.Comment: 12 pages, 3 figures.
