We present the first analysis of the extended source CXOU J163802.6--471358,which was discovered serendipitously during the {\em Chandra} X-ray survey ofthe Norma region of the Galactic spiral arms. The X-ray source exhibits acometary appearance with a point source and an extended tail region. Thecomplete source spectrum is fitted well with an absorbed power law model andjointly fitting the {\em Chandra} spectrum of the full source with one obtainedfrom an archived {\em XMM-Newton} observation results in best fit parameters$N_{\rm H}$ $=1.5^{+0.7}_{-0.5}\times10^{23} \text{cm}{^{-2}}$ and$\Gamma=1.1^{+0.7}_{-0.6}$ (90$%$ confidence uncertainties). The unabsorbedluminosity of the full source is then $L_X\sim 4.8\times10^{33}d_{10}^2$ergss$^{-1}$ with $d_{10}=d/10$kpc, where a distance of 10 kpc is a lower boundinferred from the large column density. The radio counterpart found for thesource using data from the Molonglo Galactic Plane Survey epoch-2 (MGPS-2)shows an elongated tail offset from the X-ray emission. No infrared counterpartwas found. The results are consistent with the source being a previouslyunknown pulsar driving a bow shock through the ambient medium.
