We wish to emphasize here that some sources listed in this catalogue are still uncertain. They need to be regarded with caution in view of many further work necessary to be done. Some sources are tentatively classfied as massive X-ray binaries due to their X-ray transience and hard X-ray spectra. No counterpart at other bands has been found or no pulse period has been detected, or both. Also, the compact object in some weak or soft X-ray sources may be a white dwarf instead of a neutron star. If this is the case, they should be excluded from this catalogue.

Finally, we would like to make some remarks on several individual sources. We can't make sure whether these sources belong to HMXBs or not. The following three sources are listed in our catalogue, although some doubt has been reported in the literature on the nature of the high-mass X-ray binary.

1WGA J 0648.0-4419: The weak X-ray source with a pulsation of 13 s was discovered by Israel et al. (1997) from ROSAT PSPC data. They believed that the system contained a hydrogen-depleted subdwarf O6 star and most likely a neutron star. But Bisscheroux et al. (1997) suggested the compact companion is a white dwarf star instead of a neutron star, mainly due to the ultrasoft spectrum of the X-ray source and the very close resemblance of the X-ray spectrum and luminosity with that of the soft intermediate polars.

1E 1024.0-5732: The source was discovered with Einstein Observatory. Caraveo et al. (1989) suggested that a highly reddened O5 star was the most likely optical counterpart, and therefore proposed the system was a HMXB. The source was listed in the previous catalogue. New optical and X-ray data, however, favour that the system contains a Wolf-Rayet star and an O-type star (Mereghetti et al. 1994; Reig 1999). The origin of the X-rays from this source is explained by the colliding wind binary model (Reig 1999).

1E 1048.1-5937: Although the source was listed in van Paradijs's catalogue, the system can not be confirmed to be a HMXB or a LMXB. The compact star belongs to the "anomalous" X-ray pulsars, which are thought now to be related to the magnetars. Mereghetti et al. (1998) argued that if it has a companion this star must be either a white dwarf or a helium burning star instead of a main-sequence companion.

The following two sources are not listed in our catalogue, although some authors argued that the sources are Be/X-ray binaries. GRS 1915+105: The source was listed in van Paradijs' catalogue of low-mass X-ray binaries (LMXBs). Its compact is well accepted as a black hole candidate. Mirabel et al. (1997) argued the system was a Be/X-ray binary according to its K-band infrared spectra. On the other hand, most characteristics are consistent with a LMXB. Therefore, we prefer to consider the source to be a LMXB as before.

1WGA J 1958.2+3232: Israel et al. (1998) discovered $\sim$ 12 min X-ray pulsations in this source. Further spectral observations of the optical counterpart made Israel et al. (1999b) conclude that the X-ray source is a likely new accreting neutron star in a Be/X binary system. Negueruela et al. (2000), however, found the optical spectrum is dominated by emission lines from an accretion disk and argued that the observed X-ray and the optical characteristics are consistent with the object being an intermediate polar.

PSR B1259-63/SS 2883 is also not listed in our catalogue. The source was discovered by Johnston et al. (1992a) to be a radio pulsar in a highly eccentric orbit around the massive star SS 2883 (Johnston et al. 1992b), with an eccentricity of 0.869. The pulsar rotation period is 47.76 ms and the orbital period is 1236.79 days. X-ray observations with ROSAT, ASCA and CGRO (Cominsky et al. 1994; Greiner et al. 1995; Kaspi et al. 1995; Grove et al. 1995; Tavani et al. 1996) showed X-ray luminosity of 10³³-10³⁴, assuming a distance of 2 kpc. No X-ray pulsation was detected. Optical observations of SS 2883 exhibited strong H-Balmer emissions and the star is of spectral type of about B2e, indicating its mass to be 10 ${M}_\odot$ and its radius 6 ${R}_\odot$ (Johnston et al. 1994). The system is the only known binary where a radio pulsar is observed to interact with gaseous material from a Be star. It may be the evolutionary missing link connecting the radio pulsars to the X-ray emitting Be binaries (for recent simple review, see Tavani & Arons 1997).

Note added in proof: While the paper was under referee, Haberl F. and Sasaki M. (2000, A&A 359, 573) reported that there are more than 20 new Be/X-ray binary candidates in the SMC, which are not listed in our catalogue.
