Second-epoch ROSAT PSPC observations of the nearby barred spiral galaxy NGC 1313 show that the extended X-ray emission surrounding the bright ``nuclear'' source can be mostly attributed to at least three individual sources, each with L_{X(0.1–2.4keV)} ~ 10^38–39 ergs.s^–1 and lying within ∼2.6 kpc from the central source. One of these three sources shows up only as an extension of the nuclear source in the east-west direction but becomes more apparent after subtracting out the main source. We find no evidence for X-ray emission from hot, interstellar gas and show that if such emission is present, it has a surface brightness ≤5x10³⁶ ergs.s^–1.arcmin^–2 and an integrated X-ray luminosity less than ∼5x10³⁸ ergs.s^–1. We find that of the 10 point sources detected, four of them show definite signs of variability between the two epochs of PSPC data. We also discuss an attempted revision of the description of the point-spread function of the PSPC.
