We report observations of 
emission from molecular clouds
in a complex extending 
2 kpc south of 30 Dor in the Large Magellanic
Cloud. The observations were taken on the Swedish-ESO
Submillimetre Telescope (SEST) as part of the Key Programme: CO in
the Magellanic Clouds. This paper presents observations of the
emission from the Central and Southern parts of that complex. In
both parts, the strongest emission has 
. This is a factor
of 
to 5 weaker than we would expect for Milky Way GMCs observed
at a distance of 50 kpc. In the Central region, the emission is
dominated by a 600 pc long, slightly curved feature, which is
clearly seen in peak and integrated intensity maps. When we look at this
emission in 5 km s
velocity ranges, it breaks into 22 clouds whose
sizes and line profiles look like that from Milky Way molecular
clouds. The Southern region is clearly separated from the Central
region, and its emission can be broken into 5 clouds.
