  The discovery of coherent pulsations with ASCA from an X-ray source, AX
J0049.5-7323, is reported. The barycentric period was determined to be 755.5
+/- 0.6 s, which is the longest among X-ray pulsators in the SMC. The X-ray
spectrum has been found to be unchanged through ASCA observations, with a
photon index of ~0.8 and a luminosity of ~5e35 erg s^-1 (0.7-10 keV). Archival
data of the Einstein and the ROSAT satellites indicate that the flux has been <
1e-12 erg s^-1 cm^-2 (< 5e35 erg s^-1) for over 20 years and exhibits a
variability with a factor of >10. We argue that AX J0049.5-7323 is an X-ray
pulsar with a Be star companion.
