We present data on six Southern sky sources -IM Lup, SAO 206462 (HD 135344b), HD 142527, AS 209, AS 205, and V4046 Sgr- which complement the six sources in the Taurus star-forming region reported previously. CO 2-1 and HCO^+^ 3-2 emission are detected and resolved in all disks and show velocity patterns consistent with Keplerian rotation. Where detected, the emission from DCO^+^ 3-2, N_2_H^+^ 3-2, H_2_CO 3_0 3_-2_0 2_ and 4_1 4_-3_1 3_, HCN 3-2, and CN 2_3 3/4/2_-1_2 2/3/1_ are also generally spatially resolved. The detection rates are highest toward the M and K stars, while the F star SAO 206462 has only weak CN and HCN emission, and H2CO alone is detected toward HD 142527.2011ApJ...734...98Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/734/98CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/73 : Emission-Line Stars of the Orion Population (Herbig+ 1988)J/ApJ/720/480 : DISCS.
