  An AAT/2dF Spectrograph Survey of low Galactic latitudes targeting the
putative Canis Major dwarf galaxy, and the (possibly) associated tidal debris
of stars known as the Monoceros Ring, covering Galactic coordinates
231.5$^{\circ}< ${\it l} $<$ 247.5$^{\circ}$ and -11.8$^{\circ}<${\it
b}$<-3.8^{\circ}$, has revealed the presence of the Monoceros Ring in the
background of the Canis Major dwarf galaxy. This detection resides at a
galactocentric distance of $\sim18.9\pm$0.3\kpc (13.5$\pm$0.3\kpc
heliocentric), exhibiting a velocity of $\sim132.8\pm$1.3 $\kms$ with a
dispersion of $\sim22.7\pm1.7\kms$; both of these comparable with previous
measurements of the Monoceros Ring in nearby fields. This detection highlights
the increasing complexity of structure being revealed in recent surveys of the
Milky Way thick disk and Halo.
