  We have previously conducted a search for X-ray sources coincident with white
dwarfs using the white dwarf catalog compiled by McCook & Sion (1999} and the
ROSAT sources in the WGACAT (Paper I). To include the white dwarfs discovered
since 1999 and to include the X-ray sources detected in ROSAT Position
Sensitive Proportional Counter (PSPC) observations made with a boron filter, we
have carried out another search using an updated list of white dwarfs and the
final catalogs of the ROSAT PSPC observations with and without a boron filter.
Forty-seven new X-ray sources convincingly coincident with white dwarfs are
found and reported in this paper. Among these, only 5 show hard X-ray emission:
three possess confirmed or suggested late-type companions, one is apparently
single, and the other is likely a misclassified BL Lac object. The apparently
single white dwarf with hard X-ray emission, KPD 0005+5106, was discussed
extensively in Paper I. Photospheric origin for the hard X-ray emission from
hot DO and DQZO white dwarfs remains a tantalizing possibility, but
high-quality near IR spectroscopic observations and monitoring of the H-alpha
emission line are needed to rule out the existence of a faint dMe companion.
