For the last ten years faint ionized gas detection has been carried out for elliptical galaxies with success. The kinematics is essential to understand galaxy gas origin and fate. Here we present a sample of 11 elliptical and lenticular galaxies observed with the "Cigale" scanning Perot-Fabry instrument. For each galaxy monochromatic and velocity map of ionized gas is presented. Geometrical properties such as viewing angles and axis ratios are also derived from observations. Double gaseous components are found in 3 galaxies of our sample, implying an external origin for at least part of the observed gas.
