Abstract
THE confusion caused by the rather indefinite and entirely irrational delimitation of boundaries between constellations has now been successfully attacked by the International Astronomical Union's commission on notation. No reform could be reasonably expected to ignore entirely the old traditional boundaries, or to transfer important stars into adjacent constellations, and this point has been fully recognised by the commission. The suggested scheme defines boundaries everywhere as portions either of hour circles or parallels of declination, but in such a way as to follow approximately the old boundaries. Nearly all stars with Bayer or Flamsteed designations, and all variables discovered before July 1929, remain in the constellation to which they were previously assigned.
