Abstract
We present results from the third portion of the Methanol Multibeam Galactic plane survey of masers at 6668 MHz. It covers the longitude range 330°-345°, yielding 198 masers, of which more than 40per cent are new discoveries. The maser population in this longitude range is the densest anywhere in the Galaxy, with many sources delineating a large portion of the Norma spiral arm close to its tangent point, and a cluster defining the southern tangent point of the 3-kpc ring. Two sources lie outside the solar circle, on the far side of the Galaxy, more than 15kpc away.
