The last of the old batch of "Italian" variables lists, here is a modest
revision with improved positions and IDs for 99 variables found in Cygnus by
Margoni & Stagni. Five of the stars were misidentified in my original
revision (IBVS 4431), two because the M&S charts appear to have the wrong
star marked. The changes are < 30" in all cases.
MSX and NSV and recent name-list IDs have been added, and many of the
notes made more specific.
