We report on further detections of new high energy sources from the Swift
Burst Alert Telescope (BAT) hard X-ray survey, and subsequent follow-up
observations with the X-ray Telescope (XRT). For previously reported
sources and an explanation of the BAT survey observing campaign are given
by Tueller et al. (ATEL #668, ATEL #669).
In the table below, the sources are identified by their Swift/BAT name and XRT
localized position, followed by their likely identification and
classification, where appropriate. A full Swift/XRT name is given in the case
where no previously identified source is consistent with the XRT position. The original BAT-only positions are
accurate to within ~3 arcmin (90%). The XRT 90% containment error radius
for each localization is given in arc seconds in the "ER" column
below. These positions are calculated using the latest XRT boresight
correction (e.g. Moretti et al., 2005).

(1) - Identification is the best candidate, but large (3.6') distance from BAT position
makes this uncertain.
(2) - Error circle consistent with B=17.0 optical source in the USNO catalogue
(3) - Reported emission up to 150 keV from BeppoSAX observations (Elvis et al., 2000)
