It is suggested that a group of a southern T-Tauri stars presented by V 4046 Sgr (HDE 319139), Co-2711363, AS 218, and TW Hya, located relatively far from any known dark or molecular clouds, were formed in very small clouds leaving almost no residuals, instead of having escaped from a cloud as suggested in the past of a similar isolated T-Tauri type star (FK Ser). Star V 4046 Sgr is the only group that is double and that presents a large far infrared residual measured from IRAS. Simultaneous observations of V 4046 Sgr in the UV obtained with the IUE and in the optical range by ground based observations are presented.
