Rotation curves and velocity dispersion profiles are presented for both thestellar and gaseous components along five different position angles (P.A.=5,50, 95, 125 and 155 degrees) of the nearby barred spiral NGC 6221. The observedkinematics extends out to about 80" from the nucleus. Narrow and broad-bandimaging is also presented. The radial profiles of the fluxes ratio [NII]/Halphareveal the presence of a ring-like structure of ionized gas, with a radius ofabout 9" and a deprojected circular velocity of about 280 km/s. The analysis ofthe dynamics of the bar indicates this ring is related to the presence of aninner Lindblad resonance (ILR) at 1.3 kpc. NGC6221 is found to exhibitintermediate properties between those of the early-type barred galaxies: thepresence of a gaseous ring at an ILR, the bar edge located between the ILR'sand the corotation radius beyond the steep rising portion of the rotationcurve, the dust-lane pattern, and those of the late-type galaxies: an almostexponential surface brightness profile, the presence of Halpha regions alongall the bar, the spiral-arm pattern. It is consistent with scenarios ofbar-induced evolution from later to earlier-type galaxies.Comment: 1 File ds7406.tar.gz which contains: one latex file (ds7406.tex), and  10 encsulated postscript figures (ds7406f**.eps).
