Abstract

We discuss the kinematics and the morphology of NGC 4442, a SB0 galaxy where the complex bar+lens appears in the images as a thick, boxy structure, but oblique with respect to the disc. This characteristic allows one to recognize the object as a barred galaxy and distinguish it from a boxy-bulged galaxy. The analysis of the morphology and kinematics of this galaxy shows that its properties are similar to those of the boxy and peanut bulges, supporting the hypothesis that these kind ofstructures are connected with edge-on bars. A comparison of our data (image, rotation curves and velocity dispersion profiles) with a modelof thick bar presented in the literature shows a very good agreement.
